DESCRIPTION
       The QPushButton widget provides a command button.

       The push button, or command button, is perhaps the most commonly used
       widget in any graphical user interface. Push (click) a button to
       command the computer to perform some action, or to answer a question.
       Typical buttons are OK, Apply, Cancel, Close, Yes, No and Help.

       A command button is rectangular and typically displays a text label
       describing its action. An underlined character in the label (signified
       by preceding it with an ampersand in the text) indicates an accelerator
       key, e.g.

	       QPushButton *pb = new QPushButton( "&Download", this );
       In this example the accelerator is Alt+D, and the label text will be
       displayed as <u>D</u>ownload.

       Push buttons can display a textual label or a pixmap, and optionally a
       small icon. These can be set using the constructors and changed later
       using setText(), setPixmap() and setIconSet(). If the button is
       disabled the appearance of the text or pixmap and iconset will be
       manipulated with respect to the GUI style to make the button look
       "disabled".

       A push button emits the signal clicked() when it is activated by the
       mouse, the Spacebar or by a keyboard accelerator. Connect to this
       signal to perform the button's action. Push buttons also provide less
       commonly used signals, for example, pressed() and released().

       Command buttons in dialogs are by default auto-default buttons, i.e.
       they become the default push button automatically when they receive the
       keyboard input focus. A default button is a push button that is
       activated when the user presses the Enter or Return key in a dialog.
       You can change this with setAutoDefault(). Note that auto-default
       buttons reserve a little extra space which is necessary to draw a
       default-button indicator. If you do not want this space around your
       buttons, call setAutoDefault(FALSE).

       Being so central, the button widget has grown to accommodate a great
       many variations in the past decade. The Microsoft style guide now shows
       about ten different states of Windows push buttons and the text implies
       that there are dozens more when all the combinations of features are
       taken into consideration.

       The most important modes or states are:

       Available or not (grayed out, disabled).

       Standard push button, toggling push button or menu button.

       On or off (only for toggling push buttons).

       Default or normal. The default button in a dialog can generally be
       "clicked" using the Enter or Return key.

       Auto-repeat or not.

       Pressed down or not.

       As a general rule, use a push button when the application or dialog
       window performs an action when the user clicks on it (such as Apply,
       Cancel, Close and Help) and when the widget is supposed to have a wide,
       rectangular shape with a text label. Small, typically square buttons
       that change the state of the window rather than performing an action
       (such as the buttons in the top-right corner of the QFileDialog) are
       not command buttons, but tool buttons. Qt provides a special class
       (QToolButton) for these buttons.

       If you need toggle behavior (see setToggleButton()) or a button that
       auto-repeats the activation signal when being pushed down like the
       arrows in a scroll bar (see setAutoRepeat()), a command button is
       probably not what you want. When in doubt, use a tool button.

       A variation of a command button is a menu button. These provide not
       just one command, but several, since when they are clicked they pop up
       a menu of options. Use the method setPopup() to associate a popup menu
       with a push button.

       Other classes of buttons are option buttons (see QRadioButton) and
       check boxes (see QCheckBox).

       In Qt, the QButton abstract base class provides most of the modes and
       other API, and QPushButton provides GUI logic. See QButton for more
       information about the API.

       Push Button, and Basic Widgets.

MEMBER FUNCTION DOCUMENTATION
QPushButton::QPushButton ( QWidget * parent, const char * name = 0 )
       Constructs a push button with no text.

       The parent and name arguments are sent on to the QWidget constructor.

QPushButton::QPushButton ( const QString & text, QWidget * parent, const char
       * name = 0 )
       Constructs a push button called name with the parent parent and the
       text text.

QPushButton::QPushButton ( const QIconSet & icon, const QString & text,
       QWidget * parent, const char * name = 0 )
       Constructs a push button with an icon and a text.

       Note that you can also pass a QPixmap object as an icon (thanks to the
       implicit type conversion provided by C++).

       The parent and name arguments are sent to the QWidget constructor.

QPushButton::~QPushButton ()
       Destroys the push button.

QKeySequence QButton::accel () const
       Returns the accelerator associated with the button. See the "accel"
       property for details.

bool QPushButton::autoDefault () const
       Returns TRUE if the push button is the auto default button; otherwise
       returns FALSE. See the "autoDefault" property for details.

bool QButton::autoRepeat () const
       Returns TRUE if autoRepeat is enabled; otherwise returns FALSE. See the
       "autoRepeat" property for details.

void QButton::clicked () [signal]
       This signal is emitted when the button is activated (i.e. first pressed
       down and then released when the mouse cursor is inside the button),
       when the accelerator key is typed or when animateClick() is called.
       This signal is not emitted if you call setDown().

       The QButtonGroup::clicked() signal does the same job, if you want to
       connect several buttons to the same slot.

       Warning: Don't launch a model dialog in response to this signal for a
       button that has autoRepeat turned on.

       See also pressed(), released(), toggled(), autoRepeat, and down.

       Examples:

QButtonGroup * QButton::group () const
       Returns the group that this button belongs to.

       If the button is not a member of any QButtonGroup, this function
       returns 0.

       See also QButtonGroup.

QIconSet * QPushButton::iconSet () const
       Returns the icon set on the push button. See the "iconSet" property for
       details.

bool QPushButton::isDefault () const
       Returns TRUE if the push button is the default button; otherwise
       returns FALSE. See the "default" property for details.

bool QButton::isDown () const
       Returns TRUE if the button is pressed; otherwise returns FALSE. See the
       "down" property for details.

bool QButton::isExclusiveToggle () const
       Returns TRUE if the button is an exclusive toggle; otherwise returns
       FALSE. See the "exclusiveToggle" property for details.

bool QPushButton::isFlat () const
       Returns TRUE if the border is disabled; otherwise returns FALSE. See
       the "flat" property for details.

bool QPushButton::isMenuButton () const
       Returns TRUE if the push button has a menu button on it; otherwise
       returns FALSE. See the "menuButton" property for details.

bool QButton::isOn () const
       Returns TRUE if the button is toggled; otherwise returns FALSE. See the
       "on" property for details.

bool QButton::isToggleButton () const
       Returns TRUE if the button is a toggle button; otherwise returns FALSE.
       See the "toggleButton" property for details.

const QPixmap * QButton::pixmap () const
       Returns the pixmap shown on the button. See the "pixmap" property for
       details.

QPopupMenu * QPushButton::popup () const
       Returns the button's associated popup menu or 0 if no popup menu has
       been set.

       See also setPopup().

void QButton::pressed () [signal]
       This signal is emitted when the button is pressed down.

       See also released() and clicked().

       Examples:

void QButton::released () [signal]
       This signal is emitted when the button is released.

       See also pressed(), clicked(), and toggled().

void QButton::setAccel ( const QKeySequence & ) [virtual]
       Sets the accelerator associated with the button. See the "accel"
       property for details.

void QPushButton::setAutoDefault ( bool autoDef ) [virtual]
       Sets whether the push button is the auto default button to autoDef. See
       the "autoDefault" property for details.

void QButton::setAutoRepeat ( bool ) [virtual]
       Sets whether autoRepeat is enabled. See the "autoRepeat" property for
       details.

void QPushButton::setDefault ( bool def ) [virtual]
       Sets whether the push button is the default button to def. See the
       "default" property for details.

void QButton::setDown ( bool ) [virtual]
       Sets whether the button is pressed. See the "down" property for
       details.

void QPushButton::setFlat ( bool )
       Sets whether the border is disabled. See the "flat" property for
       details.

void QPushButton::setIconSet ( const QIconSet & )
       Sets the icon set on the push button. See the "iconSet" property for
       details.

void QPushButton::setIsMenuButton ( bool enable ) [virtual]
       This function is obsolete. It is provided to keep old source working.
       We strongly advise against using it in new code.

void QPushButton::setOn ( bool ) [virtual slot]
       Sets whether the push button is toggled. See the "on" property for
       details.

void QButton::setPixmap ( const QPixmap & ) [virtual]
       Sets the pixmap shown on the button. See the "pixmap" property for
       details.

void QPushButton::setPopup ( QPopupMenu * popup )
       Associates the popup menu popup with this push button. This turns the
       button into a menu button.

       Ownership of the popup menu is not transferred to the push button.

       See also popup().

       Examples:

void QButton::setText ( const QString & ) [virtual]
       Sets the text shown on the button. See the "text" property for details.

void QPushButton::setToggleButton ( bool )
       Sets whether the button is a toggle button. See the "toggleButton"
       property for details.

ToggleState QButton::state () const
       Returns the state of the toggle button. See the "toggleState" property
       for details.

void QButton::stateChanged ( int state ) [signal]
       This signal is emitted whenever a toggle button changes state. state is
       On if the button is on, NoChange if it is in the" no change" state or
       Off if the button is off.

       This may be the result of a user action, toggle() slot activation,
       setState(), or because setOn() was called.

       See also clicked() and QButton::ToggleState.

QString QButton::text () const
       Returns the text shown on the button. See the "text" property for
       details.

void QButton::toggle () [slot]
       Toggles the state of a toggle button.

       See also on, on, toggled(), and toggleButton.

void QButton::toggled ( bool on ) [signal]
       This signal is emitted whenever a toggle button changes status. on is
       TRUE if the button is on, or FALSE if the button is off.

       This may be the result of a user action, toggle() slot activation, or
       because setOn() was called.

       See also clicked().

       Example: listbox/listbox.cpp.

   Property Documentation
QKeySequence accel
       This property holds the accelerator associated with the button.

       This property is 0 if there is no accelerator set. If you set this
       property to 0 then any current accelerator is removed.

       Set this property's value with setAccel() and get this property's value
       with accel().

bool autoDefault
       This property holds whether the push button is the auto default button.

       If this property is set to TRUE then the push button is the auto
       default button in a dialog.

       In some GUI styles a default button is drawn with an extra frame around
       it, up to 3 pixels or more. Qt automatically keeps this space free
       around auto-default buttons, i.e. auto-default buttons may have a
       slightly larger size hint.

       This property's default is TRUE for buttons that have a QDialog parent;
       otherwise it defaults to FALSE.

       See the default property for details of how default and auto-default
       interact.

       Set this property's value with setAutoDefault() and get this property's
       value with autoDefault().

bool autoMask
       This property holds whether the button is automatically masked.

       See also QWidget::autoMask.

bool autoRepeat
       This property holds whether autoRepeat is enabled.

       If autoRepeat is enabled then the clicked() signal is emitted at
       regular intervals if the button is down. This property has no effect on
       toggle buttons. autoRepeat is off by default.

       Set this property's value with setAutoRepeat() and get this property's
       value with autoRepeat().

bool default
       This property holds whether the push button is the default button.

       If this property is set to TRUE then the push button will be pressed if
       the user presses the Enter (or Return) key in a dialog.

       Regardless of focus, if the user presses Enter: If there is a default
       button the default button is pressed; otherwise, if there are one or
       more autoDefault buttons the first autoDefault button that is next in
       the tab order is pressed. If there are no default or autoDefault
       buttons only pressing Space on a button with focus, mouse clicking, or
       using an accelerator will press a button.

       In a dialog, only one push button at a time can be the default button.
       This button is then displayed with an additional frame (depending on
       the GUI style).

       The default button behavior is provided only in dialogs. Buttons can
       always be clicked from the keyboard by pressing Enter (or Return) or
       the Spacebar when the button has focus.

       This property's default is FALSE.

       Set this property's value with setDefault() and get this property's
       value with isDefault().

bool flat
       This property holds whether the border is disabled.

       This property's default is FALSE.

       Set this property's value with setFlat() and get this property's value
       with isFlat().

QIconSet iconSet
       This property holds the icon set on the push button.

       This property will return 0 if the push button has no iconset.

       Set this property's value with setIconSet() and get this property's
       value with iconSet().

bool menuButton
       This property holds whether the push button has a menu button on it.

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

       If this property is set to TRUE, then a down arrow is drawn on the push
       button to indicate that a menu will pop up if the user clicks on the
       arrow.

       Get this property's value with isMenuButton().

bool on
       This property holds whether the push button is toggled.

       This property should only be set for toggle push buttons. The default
       value is FALSE.

       See also on, toggle(), toggled(), and toggleButton.

       Set this property's value with setOn().

QPixmap pixmap
       This property holds the pixmap shown on the button.

       If the pixmap is monochrome (i.e. it is a QBitmap or its depth is 1)
       and it does not have a mask, this property will set the pixmap to be
       its own mask. The purpose of this is to draw transparent bitmaps which
       are important for toggle buttons, for example.

       pixmap() returns 0 if no pixmap was set.

       Set this property's value with setPixmap() and get this property's
       value with pixmap().

QString text
       This property holds the text shown on the button.

       This property will return a QString::null if the button has no text. If
       the text has an ampersand (&) in it, then an accelerator is
       automatically created for it using the character that follows the '&'
       as the accelerator key. Any previous accelerator will be overwritten,
       or cleared if no accelerator is defined by the text.

       There is no default text.

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

bool toggleButton
       This property holds whether the button is a toggle button.

       Toggle buttons have an on/off state similar to check boxes. A push
       button is initially not a toggle button.

       See also on, toggle(), toggleButton, and toggled().

       Set this property's value with setToggleButton().
