Detailed Description
The QCheckTableItem class provides checkboxes in QTables.
A QCheckTableItem is a table item which looks and behaves like a
checkbox. The advantage of using QCheckTableItems rather than real
checkboxes is that a QCheckTableItem uses far less resources than
a real checkbox would in a QTable. When the cell has the focus
it displays a real checkbox which the user can interact with. When
the cell does not have the focus the cell looks like a
checkbox. Pixmaps may not be used in QCheckTableItems.
QCheckTableItem items have the edit type WhenCurrent (see
EditType).
To change the checkbox's label use setText(). The checkbox can be
checked and unchecked with setChecked() and its state retrieved
using isChecked().
To populate a table cell with a QCheckTableItem use
QTable::setItem().
QCheckTableItems can be distinguished from QTableItems and
QComboTableItems using their Run Time Type Identification
(rtti) value.
See also rtti(), EditType, QComboTableItem, QTableItem, QCheckBox, and Advanced Widgets.
Member Function Documentation
QCheckTableItem::QCheckTableItem ( QTable * table, const QString & txt )
Creates a QCheckTableItem with an EditType of WhenCurrent
as a child of table. The checkbox is initially unchecked and
its label is set to the string txt.
bool QCheckTableItem::isChecked () const
Returns TRUE if the checkbox table item is checked; otherwise
returns FALSE.
See also setChecked().
int QCheckTableItem::rtti () const [virtual]
Returns 2.
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 QCheckTableItem::setChecked ( bool b ) [virtual]
If b is TRUE the checkbox is checked; if b is FALSE the
checkbox is unchecked.
See also isChecked().
