Introduction and Concepts
       QTextEdit is an advanced WYSIWYG viewer/editor supporting rich text
       formatting using HTML-style tags. It is optimized to handle large
       documents and to respond quickly to user input.

       QTextEdit has four modes of operation: <center>.nf

       </center>

       <sup>1.</sup><small>A more complete API that supports setting margins,
       images, etc., is planned for a later Qt release.</small>

       QTextEdit can be used as a syntax highlighting editor when used in
       conjunction with QSyntaxHighlighter.

       We recommend that you always call setTextFormat() to set the mode you
       want to use. If you use AutoText then setText() and append() will try
       to determine whether the text they are given is plain text or rich
       text. If you use RichText then setText() and append() will assume that
       the text they are given is rich text. insert() simply inserts the text
       it is given.

       QTextEdit works on paragraphs and characters. A paragraph is a
       formatted string which is word-wrapped to fit into the width of the
       widget. By default when reading plain text, one newline signify a
       paragraph. A document consists of zero or more paragraphs, indexed from
       0. Characters are indexed on a per-paragraph basis, also indexed from
       0. The words in the paragraph are aligned in accordance with the
       paragraph's alignment(). Paragraphs are separated by hard line breaks.
       Each character within a paragraph has its own attributes, for example,
       font and color.

       The text edit documentation uses the following concepts:

       current format -- this is the format at the current cursor position,
       and it is the format of the selected text if any.

       current paragraph -- the paragraph which contains the cursor.

       QTextEdit can display images (using QMimeSourceFactory), lists and
       tables. If the text is too large to view within the text edit's
       viewport, scrollbars will appear. The text edit can load both plain
       text and HTML files (a subset of HTML 3.2 and 4). The rendering style
       and the set of valid tags are defined by a styleSheet(). Custom tags
       can be created and placed in a custom style sheet. Change the style
       sheet with setStyleSheet(); see QStyleSheet for details. The images
       identified by image tags are displayed if they can be interpreted using
       the text edit's QMimeSourceFactory; see setMimeSourceFactory().

       If you want a text browser with more navigation use QTextBrowser. If
       you just need to display a small piece of rich text use QLabel or
       QSimpleRichText.

       If you create a new QTextEdit, and want to allow the user to edit rich
       text, call setTextFormat(Qt::RichText) to ensure that the text is
       treated as rich text. (Rich text uses HTML tags to set text formatting
       attributes. See QStyleSheet for information on the HTML tags that are
       supported.). If you don't call setTextFormat() explicitly the text edit
       will guess from the text itself whether it is rich text or plain text.
       This means that if the text looks like HTML or XML it will probably be
       interpreted as rich text, so you should call
       setTextFormat(Qt::PlainText) to preserve such text.

       Note that we do not intend to add a full-featured web browser widget to
       Qt (because that would easily double Qt's size and only a few
       applications would benefit from it). The rich text support in Qt is
       designed to provide a fast, portable and efficient way to add
       reasonable online help facilities to applications, and to provide a
       basis for rich text editors.

Using QTextEdit as a Display Widget
       QTextEdit can display a large HTML subset, including tables and images.

       The text is set or replaced using setText() which deletes any existing
       text and replaces it with the text passed in the setText() call. If you
       call setText() with legacy HTML (with setTextFormat(RichText) in
       force), and then call text(), the text that is returned may have
       different markup, but will render the same. Text can be inserted with
       insert(), paste(), pasteSubType() and append(). Text that is appended
       does not go into the undo history; this makes append() faster and
       consumes less memory. Text can also be cut(). The entire text is
       deleted with clear() and the selected text is deleted with
       removeSelectedText(). Selected (marked) text can also be deleted with
       del() (which will delete the character to the right of the cursor if no
       text is selected).

       Loading and saving text is achieved using setText() and text(), for
       example:

	   QFile file( fileName ); // Read the text from a file
	   if ( file.open( IO_ReadOnly ) ) {
	       QTextStream stream( &file );
	       textEdit->setText( stream.read() );
	   }
	   QFile file( fileName ); // Write the text to a file
	   if ( file.open( IO_WriteOnly ) ) {
	       QTextStream stream( &file );
	       stream << textEdit->text();
	       textEdit->setModified( FALSE );
	   }

       By default the text edit wraps words at whitespace to fit within the
       text edit widget. The setWordWrap() function is used to specify the
       kind of word wrap you want, or NoWrap if you don't want any wrapping.
       Call setWordWrap() to set a fixed pixel width FixedPixelWidth, or
       character column (e.g. 80 column) FixedColumnWidth with the pixels or
       columns specified with setWrapColumnOrWidth(). If you use word wrap to
       the widget's width WidgetWidth, you can specify whether to break on
       whitespace or anywhere with setWrapPolicy().

       The background color is set differently than other widgets, using
       setPaper(). You specify a brush style which could be a plain color or a
       complex pixmap.

       Hypertext links are automatically underlined; this can be changed with
       setLinkUnderline(). The tab stop width is set with setTabStopWidth().

       The zoomIn() and zoomOut() functions can be used to resize the text by
       increasing (decreasing for zoomOut()) the point size used. Images are
       not affected by the zoom functions.

       The lines() function returns the number of lines in the text and
       paragraphs() returns the number of paragraphs. The number of lines
       within a particular paragraph is returned by linesOfParagraph(). The
       length of the entire text in characters is returned by length().

       You can scroll to an anchor in the text, e.g. <a name="anchor"> with
       scrollToAnchor(). The find() function can be used to find and select a
       given string within the text.

       A read-only QTextEdit provides the same functionality as the (obsolete)
       QTextView. (QTextView is still supplied for compatibility with old
       code.)

       <h4> Read-only key bindings </h4>

       When QTextEdit is used read-only the key-bindings are limited to
       navigation, and text may only be selected with the mouse: <center>.nf

       </center>

       The text edit may be able to provide some meta-information. For
       example, the documentTitle() function will return the text from within
       HTML <title> tags.

       The text displayed in a text edit has a context. The context is a path
       which the text edit's QMimeSourceFactory uses to resolve the locations
       of files and images. It is passed to the mimeSourceFactory() when
       quering data. (See QTextEdit() and context().)

       <h4> Using QTextEdit in LogText Mode </h4>

       Setting the text format to LogText puts the widget in a special mode
       which is optimized for very large texts. Editing, word wrap, and rich
       text support are disabled in this mode (the widget is explicitly made
       read-only). This allows the text to be stored in a different, more
       memory efficient manner. However, a certain degree of text formatting
       is supported through the use of formatting tags. A tag is delimited by
       < and >. The characters <, > and & are escaped by using <, > and
       &. A tag pair consists of a left and a right tag (or open/close
       tags). Left-tags mark the starting point for formatting, while right-
       tags mark the ending point. A right-tag always start with a / before
       the tag keyword. For example <b> and </b> are a tag pair. Tags can be
       nested, but they have to be closed in the same order as they are
       opened. For example, <b><u></u></b> is valid, while <b><u></b></u> will
       output an error message.

       By using tags it is possible to change the color, bold, italic and
       underline settings for a piece of text. A color can be specified by
       using the HTML font tag <font color=colorname>. The color name can be
       one of the color names from the X11 color database, or a RGB hex value
       (e.g #00ff00). Example of valid color tags: <font color=red>, <font
       color="light blue">, <font color="#223344">. Bold, italic and underline
       settings can be specified by the tags <b>, <i> and <u>. Note that a tag
       does not necessarily have to be closed. A valid example:

	   This is <font color=red>red</font> while <b>this</b> is <font color=blue>blue</font>.
	   <font color=green><font color=yellow>Yellow,</font> and <u>green</u>.

       Stylesheets can also be used in LogText mode. To create and use a
       custom tag, you could do the following:

	   QTextEdit * log = new QTextEdit( this );
	   log->setTextFormat( Qt::LogText );
	   QStyleSheetItem * item = new QStyleSheetItem( log->styleSheet(), "mytag" );
	   item->setColor( "red" );
	   item->setFontWeight( QFont::Bold );
	   item->setFontUnderline( TRUE );
	   log->append( "This is a <mytag>custom tag</mytag>!" );
       Note that only the color, bold, underline and italic attributes of a
       QStyleSheetItem is used in LogText mode.

       Note that you can use setMaxLogLines() to limit the number of lines the
       widget can hold in LogText mode.

       There are a few things that you need to be aware of when the widget is
       in this mode:

       Functions that deal with rich text formatting and cursor movement will
       not work or return anything valid.

       Lines are equivalent to paragraphs.

Using QTextEdit as an Editor
       All the information about using QTextEdit as a display widget also
       applies here.

       The current format's attributes are set with setItalic(), setBold(),
       setUnderline(), setFamily() (font family), setPointSize(), setColor()
       and setCurrentFont(). The current paragraph's alignment is set with
       setAlignment().

       Use setSelection() to select text. The setSelectionAttributes()
       function is used to indicate how selected text should be displayed. Use
       hasSelectedText() to find out if any text is selected. The currently
       selected text's position is available using getSelection() and the
       selected text itself is returned by selectedText(). The selection can
       be copied to the clipboard with copy(), or cut to the clipboard with
       cut(). It can be deleted with removeSelectedText(). The entire text can
       be selected (or unselected) using selectAll(). QTextEdit supports
       multiple selections. Most of the selection functions operate on the
       default selection, selection 0. If the user presses a non-selecting
       key, e.g. a cursor key without also holding down Shift, all selections
       are cleared.

       Set and get the position of the cursor with setCursorPosition() and
       getCursorPosition() respectively. When the cursor is moved, the signals
       currentFontChanged(), currentColorChanged() and
       currentAlignmentChanged() are emitted to reflect the font, color and
       alignment at the new cursor position.

       If the text changes, the textChanged() signal is emitted, and if the
       user inserts a new line by pressing Return or Enter, returnPressed() is
       emitted. The isModified() function will return TRUE if the text has
       been modified.

       QTextEdit provides command-based undo and redo. To set the depth of the
       command history use setUndoDepth() which defaults to 100 steps. To undo
       or redo the last operation call undo() or redo(). The signals
       undoAvailable() and redoAvailable() indicate whether the undo and redo
       operations can be executed.

       The indent() function is used to reindent a paragraph. It is useful for
       code editors, for example in Qt Designer's code editor Ctrl+I invokes
       the indent() function.

       <h4> Editing key bindings </h4>

       The list of key-bindings which are implemented for editing: <center>.nf

       </center>

       To select (mark) text hold down the Shift key whilst pressing one of
       the movement keystrokes, for example, Shift+Right Arrow will select the
       character to the right, and Shift+Ctrl+Right Arrow will select the word
       to the right, etc.

       By default the text edit widget operates in insert mode so all text
       that the user enters is inserted into the text edit and any text to the
       right of the cursor is moved out of the way. The mode can be changed to
       overwrite, where new text overwrites any text to the right of the
       cursor, using setOverwriteMode().

       QTextEdit::ActionReturn - Split the paragraph at the cursor position.

       QTextEdit::ActionKill - If the cursor is not at the end of the
       paragraph, delete the text from the cursor position until the end of
       the paragraph. If the cursor is at the end of the paragraph, delete the
       hard line break at the end of the paragraph: this will cause this
       paragraph to be joined with the following paragraph.

       QTextEdit::ActionWordBackspace - Delete the word to the left of the
       cursor position.

       QTextEdit::ActionWordDelete - Delete the word to the right of the
       cursor position

QTextEdit::VerticalAlignment
       This enum is used to set the vertical alignment of the text.

       QTextEdit::AlignNormal - Normal alignment

       QTextEdit::AlignSuperScript - Superscript

       QTextEdit::AlignSubScript - Subscript

QTextEdit::WordWrap
       This enum defines the QTextEdit's word wrap modes.

       QTextEdit::NoWrap - Do not wrap the text.

       QTextEdit::WidgetWidth - Wrap the text at the current width of the
       widget (this is the default). Wrapping is at whitespace by default;
       this can be changed with setWrapPolicy().

       QTextEdit::FixedPixelWidth - Wrap the text at a fixed number of pixels
       from the widget's left side. The number of pixels is set with
       wrapColumnOrWidth().

       QTextEdit::FixedColumnWidth - Wrap the text at a fixed number of
       character columns from the widget's left side. The number of characters
       is set with wrapColumnOrWidth(). This is useful if you need formatted
       text that can also be displayed gracefully on devices with monospaced
       fonts, for example a standard VT100 terminal, where you might set
       wrapColumnOrWidth() to 80.

       See also wordWrap and wordWrap.

QTextEdit::WrapPolicy
       This enum defines where text can be wrapped in word wrap mode.

       QTextEdit::AtWhiteSpace - Don't use this deprecated value (it is a
       synonym for AtWordBoundary which you should use instead).

       QTextEdit::Anywhere - Break anywhere, including within words.

       QTextEdit::AtWordBoundary - Break lines at word boundaries, e.g. spaces
       or newlines

       QTextEdit::AtWordOrDocumentBoundary - Break lines at whitespace, e.g.
       spaces or newlines if possible. Break it anywhere otherwise.

       See also wrapPolicy.

MEMBER FUNCTION DOCUMENTATION
QTextEdit::QTextEdit ( const QString & text, const QString & context =
       QString::null, QWidget * parent = 0, const char * name = 0 )
       Constructs a QTextEdit called name, with parent parent. The text edit
       will display the text text using context context.

       The context is a path which the text edit's QMimeSourceFactory uses to
       resolve the locations of files and images. It is passed to the
       mimeSourceFactory() when quering data.

       For example if the text contains an image tag, <img src="image.png">,
       and the context is "path/to/look/in", the QMimeSourceFactory will try
       to load the image from" path/to/look/in/image.png". If the tag was <img
       src="/image.png">, the context will not be used (because
       QMimeSourceFactory recognizes that we have used an absolute path) and
       will try to load "/image.png". The context is applied in exactly the
       same way to hrefs, for example, <a href="target.html">Target</a>, would
       resolve to" path/to/look/in/target.html".

QTextEdit::QTextEdit ( QWidget * parent = 0, const char * name = 0 )
       Constructs an empty QTextEdit called name, with parent parent.

int QTextEdit::alignment () const
       Returns the alignment of the current paragraph.

       See also setAlignment().

QString QTextEdit::anchorAt ( const QPoint & pos, AnchorAttribute attr )
       If there is an anchor at position pos (in contents coordinates), the
       text for attribute attr is returned, otherwise QString::null is
       returned.

QString QTextEdit::anchorAt ( const QPoint & pos )
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       If there is an anchor at position pos (in contents coordinates), its
       href is returned, otherwise QString::null is returned.

void QTextEdit::append ( const QString & text ) [virtual slot]
       Appends a new paragraph with text to the end of the text edit. Note
       that the undo/redo history is cleared by this function, and no undo
       history is kept for appends which makes them faster than insert()s. If
       you want to append text which is added to the undo/redo history as
       well, use insertParagraph().

       Examples:

uint QTextEdit::autoFormatting () const
       Returns the enabled set of auto formatting features. See the
       "autoFormatting" property for details.

bool QTextEdit::bold () const
       Returns TRUE if the current format is bold; otherwise returns FALSE.

       See also setBold().

int QTextEdit::charAt ( const QPoint & pos, int * para ) const
       Returns the index of the character (relative to its paragraph) at
       position pos (in contents coordinates). If para is not 0, *para is set
       to the character's paragraph.

void QTextEdit::clear () [virtual slot]
       Deletes all the text in the text edit.

       See also cut(), removeSelectedText(), and text.

void QTextEdit::clearParagraphBackground ( int para ) [virtual slot]
       Clears the background color of the paragraph para, so that the default
       color is used again.

void QTextEdit::clicked ( int para, int pos ) [signal]
       This signal is emitted when the mouse is clicked on the paragraph para
       at character position pos.

       See also doubleClicked().

QColor QTextEdit::color () const
       Returns the color of the current format.

       See also setColor() and paper.

QString QTextEdit::context () const
       Returns the context of the text edit. The context is a path which the
       text edit's QMimeSourceFactory uses to resolve the locations of files
       and images.

       See also text.

       Examples:

void QTextEdit::copy () [virtual slot]
       Copies any selected text (from selection 0) to the clipboard.

       See also hasSelectedText and copyAvailable().

void QTextEdit::copyAvailable ( bool yes ) [signal]
       This signal is emitted when text is selected or de-selected in the text
       edit.

       When text is selected this signal will be emitted with yes set to TRUE.
       If no text has been selected or if the selected text is de-selected
       this signal is emitted with yes set to FALSE.

       If yes is TRUE then copy() can be used to copy the selection to the
       clipboard. If yes is FALSE then copy() does nothing.

       See also selectionChanged().

QPopupMenu * QTextEdit::createPopupMenu ( const QPoint & pos ) [virtual
       protected]
       This function is called to create a right mouse button popup menu at
       the document position pos. If you want to create a custom popup menu,
       reimplement this function and return the created popup menu. Ownership
       of the popup menu is transferred to the caller.

       Warning: The QPopupMenu ID values 0-7 are reserved, and they map to the
       standard operations. When inserting items into your custom popup menu,
       be sure to specify ID values larger than 7.

QPopupMenu * QTextEdit::createPopupMenu () [virtual protected]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

       This function is called to create a right mouse button popup menu. If
       you want to create a custom popup menu, reimplement this function and
       return the created popup menu. Ownership of the popup menu is
       transferred to the caller.

       This function is only called if createPopupMenu( const QPoint & )
       returns 0.

void QTextEdit::currentAlignmentChanged ( int a ) [signal]
       This signal is emitted if the alignment of the current paragraph has
       changed.

       The new alignment is a.

       See also setAlignment().

void QTextEdit::currentColorChanged ( const QColor & c ) [signal]
       This signal is emitted if the color of the current format has changed.

       The new color is c.

       See also setColor().

QFont QTextEdit::currentFont () const
       Returns the font of the current format.

       See also setCurrentFont(), setFamily(), and setPointSize().

void QTextEdit::currentFontChanged ( const QFont & f ) [signal]
       This signal is emitted if the font of the current format has changed.

       The new font is f.

       See also setCurrentFont().

void QTextEdit::currentVerticalAlignmentChanged ( VerticalAlignment a )
       [signal]
       This signal is emitted if the vertical alignment of the current format
       has changed.

       The new vertical alignment is a.

       See also setVerticalAlignment().

void QTextEdit::cursorPositionChanged ( int para, int pos ) [signal]
       This signal is emitted if the position of the cursor has changed. para
       contains the paragraph index and pos contains the character position
       within the paragraph.

       See also setCursorPosition().

void QTextEdit::cut () [virtual slot]
       Copies the selected text (from selection 0) to the clipboard and
       deletes it from the text edit.

       If there is no selected text (in selection 0) nothing happens.

       See also QTextEdit::copy(), paste(), and pasteSubType().

void QTextEdit::del () [virtual slot]
       If there is some selected text (in selection 0) it is deleted. If there
       is no selected text (in selection 0) the character to the right of the
       text cursor is deleted.

       See also removeSelectedText() and cut().

void QTextEdit::doKeyboardAction ( KeyboardAction action ) [virtual slot]
       Executes keyboard action action. This is normally called by a key event
       handler.

QString QTextEdit::documentTitle () const
       Returns the title of the document parsed from the text. See the
       "documentTitle" property for details.

void QTextEdit::doubleClicked ( int para, int pos ) [signal]
       This signal is emitted when the mouse is double-clicked on the
       paragraph para at character position pos.

       See also clicked().

void QTextEdit::ensureCursorVisible () [virtual slot]
       Ensures that the cursor is visible by scrolling the text edit if
       necessary.

       See also setCursorPosition().

QString QTextEdit::family () const
       Returns the font family of the current format.

       See also setFamily(), setCurrentFont(), and setPointSize().

bool QTextEdit::find ( const QString & expr, bool cs, bool wo, bool forward =
       TRUE, int * para = 0, int * index = 0 ) [virtual]
       Finds the next occurrence of the string, expr. Returns TRUE if expr was
       found; otherwise returns FALSE.

       If para and index are both 0 the search begins from the current cursor
       position. If para and index are both not 0, the search begins from the
       *index character position in the *para paragraph.

       If cs is TRUE the search is case sensitive, otherwise it is case
       insensitive. If wo is TRUE the search looks for whole word matches
       only; otherwise it searches for any matching text. If forward is TRUE
       (the default) the search works forward from the starting position to
       the end of the text, otherwise it works backwards to the beginning of
       the text.

       If expr is found the function returns TRUE. If index and para are not
       0, the number of the paragraph in which the first character of the
       match was found is put into *para, and the index position of that
       character within the paragraph is put into *index.

       If expr is not found the function returns FALSE. If index and para are
       not 0 and expr is not found, *index and *para are undefined.

       Please note that this function will make the next occurrence of the
       string (if found) the current selection, and will thus modify the
       cursor position.

       Using the para and index parameters will not work correctly in case the
       document contains tables.

bool QTextEdit::focusNextPrevChild ( bool n ) [virtual protected]
       Reimplemented to allow tabbing through links. If n is TRUE the tab
       moves the focus to the next child; if n is FALSE the tab moves the
       focus to the previous child. Returns TRUE if the focus was moved;
       otherwise returns FALSE.

QFont QTextEdit::font () const
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

       Returns QScrollView::font()

       Warning: In previous versions this function returned the font of the
       current format. This lead to confusion. Please use currentFont()
       instead.

       Example: qwerty/qwerty.cpp.

void QTextEdit::getCursorPosition ( int * para, int * index ) const
       This function sets the *para and *index parameters to the current
       cursor position. para and index must not be 0.

       See also setCursorPosition().

void QTextEdit::getSelection ( int * paraFrom, int * indexFrom, int * paraTo,
       int * indexTo, int selNum = 0 ) const
       If there is a selection, *paraFrom is set to the number of the
       paragraph in which the selection begins and *paraTo is set to the
       number of the paragraph in which the selection ends. (They could be the
       same.) *indexFrom is set to the index at which the selection begins
       within *paraFrom, and *indexTo is set to the index at which the
       selection ends within *paraTo.

       If there is no selection, *paraFrom, *indexFrom, *paraTo and *indexTo
       are all set to -1.

       If paraFrom, indexFrom, paraTo or indexTo is 0 this function does
       nothing.

       The selNum is the number of the selection (multiple selections are
       supported). It defaults to 0 (the default selection).

       See also setSelection() and selectedText.

bool QTextEdit::hasSelectedText () const
       Returns TRUE if some text is selected in selection 0; otherwise returns
       FALSE. See the "hasSelectedText" property for details.

int QTextEdit::heightForWidth ( int w ) const [virtual]
       Returns how many pixels high the text edit needs to be to display all
       the text if the text edit is w pixels wide.

       Reimplemented from QWidget.

void QTextEdit::insert ( const QString & text, uint insertionFlags =
       CheckNewLines | RemoveSelected ) [slot]
       Inserts text at the current cursor position.

       The insertionFlags define how the text is inserted. If RedoIndentation
       is set, the paragraph is re-indented. If CheckNewLines is set, newline
       characters in text result in hard line breaks (i.e. new paragraphs). If
       checkNewLine is not set, the behaviour of the editor is undefined if
       the text contains newlines. (It is not possible to change QTextEdit's
       newline handling behavior, but you can use QString::replace() to
       preprocess text before inserting it.) If RemoveSelected is set, any
       selected text (in selection 0) is removed before the text is inserted.

       The default flags are CheckNewLines | RemoveSelected.

       If the widget is in LogText mode this function will do nothing.

       See also paste() and pasteSubType().

void QTextEdit::insert ( const QString & text, bool indent, bool checkNewLine
       = TRUE, bool removeSelected = TRUE ) [virtual slot]
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void QTextEdit::insertAt ( const QString & text, int para, int index )
       [virtual slot]
       Inserts text in the paragraph para at position index.

void QTextEdit::insertParagraph ( const QString & text, int para ) [virtual
       slot]
       Inserts text as a new paragraph at position para. If para is -1, the
       text is appended. Use append() if the append operation is performance
       critical.

bool QTextEdit::isModified () const
       Returns TRUE if the document has been modified by the user; otherwise
       returns FALSE. See the "modified" property for details.

bool QTextEdit::isOverwriteMode () const
       Returns the text edit's overwrite mode. See the "overwriteMode"
       property for details.

bool QTextEdit::isReadOnly () const
       Returns TRUE if the text edit is read-only; otherwise returns FALSE.
       See the "readOnly" property for details.

bool QTextEdit::isRedoAvailable () const
       Returns TRUE if redo is available; otherwise returns FALSE.

bool QTextEdit::isUndoAvailable () const
       Returns TRUE if undo is available; otherwise returns FALSE.

bool QTextEdit::isUndoRedoEnabled () const
       Returns TRUE if undo/redo is enabled; otherwise returns FALSE. See the
       "undoRedoEnabled" property for details.

bool QTextEdit::italic () const
       Returns TRUE if the current format is italic; otherwise returns FALSE.

       See also setItalic().

void QTextEdit::keyPressEvent ( QKeyEvent * e ) [virtual protected]
       Processes the key event, e. By default key events are used to provide
       keyboard navigation and text editing.

       Reimplemented from QWidget.

       Reimplemented in QTextBrowser.

int QTextEdit::length () const
       Returns the number of characters in the text. See the "length" property
       for details.

int QTextEdit::lineOfChar ( int para, int index )
       Returns the line number of the line in paragraph para in which the
       character at position index appears. The index position is relative to
       the beginning of the paragraph. If there is no such paragraph or no
       such character at the index position (e.g. the index is out of range)
       -1 is returned.

int QTextEdit::lines () const
       Returns the number of lines in the text edit; this could be 0.

       Warning: This function may be slow. Lines change all the time during
       word wrapping, so this function has to iterate over all the paragraphs
       and get the number of lines from each one individually.

int QTextEdit::linesOfParagraph ( int para ) const
       Returns the number of lines in paragraph para, or -1 if there is no
       paragraph with index para.

bool QTextEdit::linkUnderline () const
       Returns TRUE if hypertext links will be underlined; otherwise returns
       FALSE. See the "linkUnderline" property for details.

int QTextEdit::maxLogLines () [slot]
       Returns the maximum number of lines QTextEdit can hold in LogText mode.
       By default the number of lines is unlimited, which is signified by a
       value of -1.

QMimeSourceFactory * QTextEdit::mimeSourceFactory () const
       Returns the QMimeSourceFactory which is being used by this text edit.

       See also setMimeSourceFactory().

       Examples:

void QTextEdit::modificationChanged ( bool m ) [signal]
       This signal is emitted when the modification status of the document has
       changed. If m is TRUE, the document was modified, otherwise the
       modification state has been reset to unmodified.

       See also modified.

void QTextEdit::moveCursor ( CursorAction action, bool select ) [virtual slot]

       Moves the text cursor according to action. This is normally used by
       some key event handler. select specifies whether the text between the
       current cursor position and the new position should be selected.

QBrush QTextEdit::paper () const
       Returns the background (paper) brush. See the "paper" property for
       details.

int QTextEdit::paragraphAt ( const QPoint & pos ) const
       Returns the paragraph which is at position pos (in contents
       coordinates).

QColor QTextEdit::paragraphBackgroundColor ( int para ) const
       Returns the background color of the paragraph para or an invalid color
       if para is out of range or the paragraph has no background set

int QTextEdit::paragraphLength ( int para ) const
       Returns the length of the paragraph para (i.e. the number of
       characters), or -1 if there is no paragraph with index para.

       This function ignores newlines.

QRect QTextEdit::paragraphRect ( int para ) const
       Returns the rectangle of the paragraph para in contents coordinates, or
       an invalid rectangle if para is out of range.

int QTextEdit::paragraphs () const
       Returns the number of paragraphs in the text; an empty textedit is
       always considered to have one paragraph, so 1 is returned in this case.

void QTextEdit::paste () [virtual slot]
       Pastes the text from the clipboard into the text edit at the current
       cursor position. Only plain text is pasted.

       If there is no text in the clipboard nothing happens.

       See also pasteSubType(), cut(), and QTextEdit::copy().

void QTextEdit::pasteSubType ( const QCString & subtype ) [virtual slot]
       Pastes the text with format subtype from the clipboard into the text
       edit at the current cursor position. The subtype can be" plain" or
       "html".

       If there is no text with format subtype in the clipboard nothing
       happens.

       See also paste(), cut(), and QTextEdit::copy().

void QTextEdit::placeCursor ( const QPoint & pos, QTextCursor * c = 0 )
       [virtual slot]
       Places the cursor c at the character which is closest to position pos
       (in contents coordinates). If c is 0, the default text cursor is used.

       See also setCursorPosition().

int QTextEdit::pointSize () const
       Returns the point size of the font of the current format.

       See also setFamily(), setCurrentFont(), and setPointSize().

void QTextEdit::redo () [virtual slot]
       Redoes the last operation.

       If there is no operation to redo, i.e. there is no redo step in the
       undo/redo history, nothing happens.

       See also redoAvailable(), undo(), and undoDepth.

void QTextEdit::redoAvailable ( bool yes ) [signal]
       This signal is emitted when the availability of redo changes. If yes is
       TRUE, then redo() will work until redoAvailable( FALSE ) is next
       emitted.

       See also redo() and undoDepth.

void QTextEdit::removeParagraph ( int para ) [virtual slot]
       Removes the paragraph para.

void QTextEdit::removeSelectedText ( int selNum = 0 ) [virtual slot]
       Deletes the text of selection selNum (by default, the default
       selection, 0). If there is no selected text nothing happens.

       See also selectedText and removeSelection().

void QTextEdit::removeSelection ( int selNum = 0 ) [virtual slot]
       Removes the selection selNum (by default 0). This does not remove the
       selected text.

       See also removeSelectedText().

void QTextEdit::repaintChanged () [protected]
       Repaints any paragraphs that have changed.

       Although used extensively internally you shouldn't need to call this
       yourself.

void QTextEdit::returnPressed () [signal]
       This signal is emitted if the user pressed the Return or the Enter key.

void QTextEdit::scrollToAnchor ( const QString & name ) [virtual slot]
       Scrolls the text edit to make the text at the anchor called name
       visible, if it can be found in the document. If the anchor isn't found
       no scrolling will occur. An anchor is defined using the HTML anchor
       tag, e.g. <a name="target">.

void QTextEdit::scrollToBottom () [virtual slot]
       Scrolls to the bottom of the document and does formatting if required.

void QTextEdit::selectAll ( bool select = TRUE ) [virtual slot]
       If select is TRUE (the default), all the text is selected as selection
       0. If select is FALSE any selected text is unselected, i.e. the default
       selection (selection 0) is cleared.

       See also selectedText.

QString QTextEdit::selectedText () const
       Returns the selected text (from selection 0) or an empty string if
       there is no currently selected text (in selection 0). See the
       "selectedText" property for details.

void QTextEdit::selectionChanged () [signal]
       This signal is emitted whenever the selection changes.

       See also setSelection() and copyAvailable().

void QTextEdit::setAlignment ( int a ) [virtual slot]
       Sets the alignment of the current paragraph to a. Valid alignments are
       Qt::AlignLeft, Qt::AlignRight, Qt::AlignJustify and Qt::AlignCenter
       (which centers horizontally).

       Reimplemented in QMultiLineEdit.

void QTextEdit::setAutoFormatting ( uint features )
       Sets the enabled set of auto formatting features to features. See the
       "autoFormatting" property for details.

void QTextEdit::setBold ( bool b ) [virtual slot]

       current format to non-bold.

       See also bold().

void QTextEdit::setColor ( const QColor & c ) [virtual slot]
       Sets the color of the current format, i.e. of the text, to c.

       See also color() and paper.

void QTextEdit::setCurrentFont ( const QFont & f ) [virtual slot]
       Sets the font of the current format to f.

       If the widget is in LogText mode this function will do nothing. Use
       setFont() instead.

       See also currentFont(), setPointSize(), and setFamily().

void QTextEdit::setCursorPosition ( int para, int index ) [virtual slot]

       See also family() and setCurrentFont().

void QTextEdit::setItalic ( bool b ) [virtual slot]
       If b is TRUE sets the current format to italic; otherwise sets the
       current format to non-italic.

       See also italic().

void QTextEdit::setLinkUnderline ( bool ) [virtual slot]
       Sets whether hypertext links will be underlined. See the
       "linkUnderline" property for details.

void QTextEdit::setMaxLogLines ( int limit ) [slot]
       Sets the maximum number of lines a QTextEdit can hold in LogText mode
       to limit. If limit is -1 (the default), this signifies an unlimited
       number of lines.

       Warning: Never use formatting tags that span more than one line when
       the maximum log lines is set. When lines are removed from the top of
       the buffer it could result in an unbalanced tag pair, i.e. the left
       formatting tag is removed before the right one.

void QTextEdit::setMimeSourceFactory ( QMimeSourceFactory * factory ) [virtual
       slot]
       Sets the text edit's mimesource factory to factory. See
       QMimeSourceFactory for further details.

       See also mimeSourceFactory().

       [virtual slot]
       Sets the background color of the paragraph para to bg.

void QTextEdit::setPointSize ( int s ) [virtual slot]
       Sets the point size of the current format to s.

       Note that if s is zero or negative, the behaviour of this function is
       not defined.

       See also pointSize(), setCurrentFont(), and setFamily().

void QTextEdit::setReadOnly ( bool b ) [virtual slot]
       Sets whether the text edit is read-only to b. See the "readOnly"
       property for details.

void QTextEdit::setSelection ( int paraFrom, int indexFrom, int paraTo, int
       indexTo, int selNum = 0 ) [virtual slot]
       Sets a selection which starts at position indexFrom in paragraph
       paraFrom and ends at position indexTo in paragraph paraTo.

       Any existing selections which have a different id (selNum) are left
       alone, but if an existing selection has the same id as selNum it is
       removed and replaced by this selection.

       Uses the selection settings of selection selNum. If selNum is 0, this
       is the default selection.

       The cursor is moved to the end of the selection if selNum is 0,
       otherwise the cursor position remains unchanged.

       See also getSelection() and selectedText.

void QTextEdit::setSelectionAttributes ( int selNum, const QColor & back, bool
       invertText ) [virtual slot]
       Sets the background color of selection number selNum to back and
       specifies whether the text of this selection should be inverted with
       invertText.

       This only works for selNum > 0. The default selection (selNum == 0)
       gets its attributes from the text edit's colorGroup().

void QTextEdit::setStyleSheet ( QStyleSheet * styleSheet ) [virtual slot]
       Sets the stylesheet to use with this text edit to styleSheet. Changes
       will only take effect for new text added with setText() or append().

       See also styleSheet().

void QTextEdit::setTabChangesFocus ( bool b ) [slot]
       Sets whether TAB changes focus or is accepted as input to b. See the
       "tabChangesFocus" property for details.

void QTextEdit::setTabStopWidth ( int ts ) [virtual slot]
       Sets the tab stop width in pixels to ts. See the "tabStopWidth"
       property for details.

void QTextEdit::setText ( const QString & txt ) [slot]
       Sets the text edit's text to txt. See the "text" property for details.

void QTextEdit::setText ( const QString & text, const QString & context )
       [virtual slot]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Changes the text of the text edit to the string text and the context to
       context. Any previous text is removed.

       text may be interpreted either as plain text or as rich text, depending
       on the textFormat(). The default setting is AutoText, i.e. the text
       edit auto-detects the format from text.

       For rich text the rendering style and available tags are defined by a
       styleSheet(); see QStyleSheet for details.

       The optional context is a path which the text edit's QMimeSourceFactory
       uses to resolve the locations of files and images. (See
       QTextEdit::QTextEdit().) It is passed to the text edit's
       QMimeSourceFactory when quering data.

       Note that the undo/redo history is cleared by this function.

       See also text and textFormat.

void QTextEdit::setTextFormat ( TextFormat f ) [virtual slot]
       Sets the text format: rich text, plain text, log text or auto text to
       f. See the "textFormat" property for details.

       details.

void QTextEdit::setWrapColumnOrWidth ( int ) [virtual slot]
       Sets the position (in pixels or columns depending on the wrap mode)
       where text will be wrapped. See the "wrapColumnOrWidth" property for
       details.

void QTextEdit::setWrapPolicy ( WrapPolicy policy ) [virtual slot]
       Sets the word wrap policy, at whitespace or anywhere to policy. See the
       "wrapPolicy" property for details.

QStyleSheet * QTextEdit::styleSheet () const
       Returns the QStyleSheet which is being used by this text edit.

       See also setStyleSheet().

       Examples:

void QTextEdit::sync () [virtual slot]
       QTextEdit is optimized for large amounts text. One of its optimizations
       is to format only the visible text, formatting the rest on demand, e.g.
       as the user scrolls, so you don't usually need to call this function.

       In some situations you may want to force the whole text to be
       formatted. For example, if after calling setText(), you wanted to know
       the height of the document (using contentsHeight()), you would call
       this function first.

QSyntaxHighlighter * QTextEdit::syntaxHighlighter () const
       Returns the QSyntaxHighlighter set on this QTextEdit. 0 is returned if
       no syntax highlighter is set.

bool QTextEdit::tabChangesFocus () const
       Returns TRUE if TAB changes focus or is accepted as input; otherwise
       returns FALSE. See the "tabChangesFocus" property for details.

       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Returns the text of paragraph para.

       If textFormat() is RichText the text will contain HTML formatting tags.

void QTextEdit::textChanged () [signal]
       This signal is emitted whenever the text in the text edit changes.

       See also text and append().

       Examples:

QTextCursor * QTextEdit::textCursor () const [protected]
       Returns the text edit's text cursor.

       Warning: QTextCursor is not in the public API, but in special
       circumstances you might wish to use it.

TextFormat QTextEdit::textFormat () const
       Returns the text format: rich text, plain text, log text or auto text.
       See the "textFormat" property for details.

bool QTextEdit::underline () const
       Returns TRUE if the current format is underlined; otherwise returns
       FALSE.

       See also setUnderline().

void QTextEdit::undo () [virtual slot]
       Undoes the last operation.

       If there is no operation to undo, i.e. there is no undo step in the
       undo/redo history, nothing happens.

       See also undoAvailable(), redo(), and undoDepth.

void QTextEdit::undoAvailable ( bool yes ) [signal]
       This signal is emitted when the availability of undo changes. If yes is
       TRUE, then undo() will work until undoAvailable( FALSE ) is next
       emitted.

       See also undo() and undoDepth.

       where text will be wrapped. See the "wrapColumnOrWidth" property for
       details.

WrapPolicy QTextEdit::wrapPolicy () const
       Returns the word wrap policy, at whitespace or anywhere. See the
       "wrapPolicy" property for details.

void QTextEdit::zoomIn ( int range ) [virtual slot]
       Zooms in on the text by making the base font size range points larger
       and recalculating all font sizes to be the new size. This does not
       change the size of any images.

       See also zoomOut().

       recalculating all font sizes to be the new size. This does not change
       the size of any images.

       See also zoomOut().

void QTextEdit::zoomOut ( int range ) [virtual slot]
       Zooms out on the text by making the base font size range points smaller
       and recalculating all font sizes to be the new size. This does not
       change the size of any images.

       See also zoomIn().

void QTextEdit::zoomOut () [virtual slot]
       This is an overloaded member function, provided for convenience. It
       behaves essentially like the above function.

       Zooms out on the text by making the base font size one point smaller
       and recalculating all font sizes to be the new size. This does not

       Zooms the text by making the base font size size points and
       recalculating all font sizes to be the new size. This does not change
       the size of any images.

   Property Documentation
AutoFormatting autoFormatting
       This property holds the enabled set of auto formatting features.

       The value can be any combination of the values in the AutoFormatting
       enum. The default is AutoAll. Choose AutoNone to disable all automatic
       formatting.

       Currently, the only automatic formatting feature provided is
       AutoBulletList; future versions of Qt may offer more.

       Set this property's value with setAutoFormatting() and get this
       property's value with autoFormatting().

QString documentTitle
       This property holds the title of the document parsed from the text.

       For PlainText the title will be an empty string. For RichText the title
       will be the text between the <title> tags, if present, otherwise an
       empty string.

       Get this property's value with documentTitle().

bool hasSelectedText
       This property holds whether some text is selected in selection 0.

       Get this property's value with hasSelectedText().

int length
       This property holds the number of characters in the text.

       Get this property's value with length().

bool linkUnderline
       This property holds whether hypertext links will be underlined.

       If TRUE (the default) hypertext links will be displayed underlined. If
       FALSE links will not be displayed underlined.

       Set this property's value with setLinkUnderline() and get this
       property's value with linkUnderline().

bool modified
       This property holds whether the document has been modified by the user.

       Set this property's value with setModified() and get this property's
       value with isModified().

bool overwriteMode
       This property holds the text edit's overwrite mode.

       If FALSE (the default) characters entered by the user are inserted with
       any characters to the right being moved out of the way. If TRUE, the
       editor is in overwrite mode, i.e. characters entered by the user
       overwrite any characters to the right of the cursor position.

       Set this property's value with setOverwriteMode() and get this
       property's value with isOverwriteMode().

QBrush paper
       This property holds the background (paper) brush.

       The brush that is currently used to draw the background of the text
       edit. The initial setting is an empty brush.

       Set this property's value with setPaper() and get this property's value
       with paper().

bool readOnly
       This property holds whether the text edit is read-only.

       In a read-only text edit the user can only navigate through the text
       and select text; modifying the text is not possible.

       This property's default is FALSE.

       Set this property's value with setReadOnly() and get this property's
       value with isReadOnly().

QString selectedText
       This property holds the selected text (from selection 0) or an empty
       string if there is no currently selected text (in selection 0).

       The text is always returned as PlainText if the textFormat() is
       PlainText or AutoText, otherwise it is returned as HTML.

       See also hasSelectedText.

       Get this property's value with selectedText().

bool tabChangesFocus
       This property holds whether TAB changes focus or is accepted as input.

       In some occasions text edits should not allow the user to input
       tabulators or change indentation using the TAB key, as this breaks the
       focus chain. The default is FALSE.

       Set this property's value with setTabChangesFocus() and get this
       property's value with tabChangesFocus().

int tabStopWidth
       This property holds the tab stop width in pixels.

       Set this property's value with setTabStopWidth() and get this
       property's value with tabStopWidth().

QString text
       This property holds the text edit's text.

       There is no default text.

       On setting, any previous text is deleted.

       The text may be interpreted either as plain text or as rich text,
       depending on the textFormat(). The default setting is AutoText, i.e.
       the text edit auto-detects the format of the text.

       For richtext, calling text() on an editable QTextEdit will cause the
       text to be regenerated from the textedit. This may mean that the
       QString returned may not be exactly the same as the one that was set.

       See also textFormat.

       Set this property's value with setText() and get this property's value
       with text().

TextFormat textFormat
       This property holds the text format: rich text, plain text, log text or
       auto text.

       The text format is one of the following:

       PlainText - all characters, except newlines, are displayed verbatim,
       including spaces. Whenever a newline appears in the text the text edit
       inserts a hard line break and begins a new paragraph.

       RichText - rich text rendering. The available styles are defined in the
       default stylesheet QStyleSheet::defaultSheet().

       LogText - optimized mode for very large texts. Supports a very limited
       set of formatting tags (color, bold, underline and italic settings).

       AutoText - this is the default. The text edit autodetects which
       rendering style is best, PlainText or RichText. This is done by using
       the QStyleSheet::mightBeRichText() function.

       Set this property's value with setTextFormat() and get this property's
       value with textFormat().

int undoDepth
       This property holds the depth of the undo history.

       The maximum number of steps in the undo/redo history. The default is
       100.

       See also undo() and redo().

       Set this property's value with setUndoDepth() and get this property's
       value with undoDepth().

bool undoRedoEnabled
       This property holds whether undo/redo is enabled.

       When changing this property, the undo/redo history is cleared.

       The default is TRUE.

       Set this property's value with setUndoRedoEnabled() and get this
       property's value with isUndoRedoEnabled().

WordWrap wordWrap
       This property holds the word wrap mode.

       The default mode is WidgetWidth which causes words to be wrapped at the
       right edge of the text edit. Wrapping occurs at whitespace, keeping
       whole words intact. If you want wrapping to occur within words use
       setWrapPolicy(). If you set a wrap mode of FixedPixelWidth or
       FixedColumnWidth you should also call setWrapColumnOrWidth() with the
       width you want.

       See also WordWrap, wrapColumnOrWidth, and wrapPolicy.

       Set this property's value with setWordWrap() and get this property's
       value with wordWrap().

int wrapColumnOrWidth
       This property holds the position (in pixels or columns depending on the
       wrap mode) where text will be wrapped.

       If the wrap mode is FixedPixelWidth, the value is the number of pixels
       from the left edge of the text edit at which text should be wrapped. If
       the wrap mode is FixedColumnWidth, the value is the column number (in
       character columns) from the left edge of the text edit at which text
       should be wrapped.

       See also wordWrap.

       Set this property's value with setWrapColumnOrWidth() and get this
       property's value with wrapColumnOrWidth().

WrapPolicy wrapPolicy
       This property holds the word wrap policy, at whitespace or anywhere.

       Defines where text can be wrapped when word wrap mode is not NoWrap.
       The choices are AtWordBoundary (the default), Anywhere and
       AtWordOrDocumentBoundary

       See also wordWrap.

       Set this property's value with setWrapPolicy() and get this property's
       value with wrapPolicy().
