DESCRIPTION
The QComboTableItem class provides a means of using comboboxes in
QTables.
A QComboTableItem is a table item which looks and behaves like a
combobox. The advantage of using QComboTableItems rather than real
comboboxes is that a QComboTableItem uses far less resources than real
comboboxes in QTables. When the cell has the focus it displays a real
combobox which the user can interact with. When the cell does not have
the focus the cell looks like a combobox. Only text items (i.e. no
pixmaps) may be used in QComboTableItems.
QComboTableItem items have the edit type WhenCurrent (see EditType).
The QComboTableItem's list of items is provided by a QStringList passed
to the constructor.
The list of items may be changed using setStringList(). The current
item can be set with setCurrentItem() and retrieved with currentItem().
The text of the current item can be obtained with currentText(), and
the text of a particular item can be retrieved with text().
If isEditable() is TRUE the QComboTableItem will permit the user to
either choose an existing list item, or create a new list item by
entering their own text; otherwise the user may only choose one of the
existing list items.
To populate a table cell with a QComboTableItem use QTable::setItem().
QComboTableItems may be deleted with QTable::clearCell().
QComboTableItems can be distinguished from QTableItems and
QCheckTableItems using their Run Time Type Identification number (see
rtti()).

MEMBER FUNCTION DOCUMENTATIONQComboTableItem::QComboTableItem ( QTable * table, const QStringList & list,
bool editable = FALSE )
Creates a combo table item for the table table. The combobox's list of
items is passed in the list argument. If editable is TRUE the user may
type in new list items; if editable is FALSE the user may only select
from the list of items provided.
By default QComboTableItems cannot be replaced by other table items
since isReplaceable() returns FALSE by default.
See also QTable::clearCell() and EditType.
QComboTableItem::~QComboTableItem ()
QComboTableItem destructor.
int QComboTableItem::count () const
Returns the total number of list items in the combo table item.
int QComboTableItem::currentItem () const
Returns the index of the combo table item's current list item.
See also setCurrentItem().
QString QComboTableItem::currentText () const
Returns the text of the combo table item's current list item.
See also currentItem() and text().
bool QComboTableItem::isEditable () const
Returns TRUE if the user can add their own list items to the combobox's
list of items; otherwise returns FALSE.
See also setEditable().
int QComboTableItem::rtti () const [virtual]
Returns 1.
Make your derived classes return their own values for rtti()to
distinguish between different table item subclasses. You should use
values greater than 1000, preferably a large random number, to allow
for extensions to this class.
See also QTableItem::rtti().
Reimplemented from QTableItem.
void QComboTableItem::setCurrentItem ( int i ) [virtual]
Sets the list item i to be the combo table item's current list item.
See also currentItem().
Example: table/small-table-demo/main.cpp.
void QComboTableItem::setCurrentItem ( const QString & s ) [virtual]
This is an overloaded member function, provided for convenience. It
behaves essentially like the above function.
Sets the list item whose text is s to be the combo table item's current
list item. Does nothing if no list item has the text s.
See also currentItem().
void QComboTableItem::setEditable ( bool b ) [virtual]
If b is TRUE the combo table item can be edited, i.e. the user may
enter a new text item themselves. If b is FALSE the user may may only
choose one of the existing items.
See also isEditable().
void QComboTableItem::setStringList ( const QStringList & l ) [virtual]
Sets the list items of this QComboTableItem to the strings in the
string list l.
QString QComboTableItem::text ( int i ) const
Returns the text of the combo's list item at index i.
See also currentText().
