The TQCheckTableItem class provides checkboxes in TQTables.
< p >
< p > A TQCheckTableItem is a table item which looks and behaves like a
checkbox. The advantage of using TQCheckTableItems rather than real
checkboxes is that a TQCheckTableItem uses far less resources than
a real checkbox would in a < a href = "ntqtable.html" > TQTable< / a > . 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 < em > looks< / em > like a
checkbox. Pixmaps may not be used in TQCheckTableItems.
< p > TQCheckTableItem items have the edit type < a href = "qtableitem.html#EditType-enum" > WhenCurrent< / a > (see
< a href = "qtableitem.html#EditType-enum" > EditType< / a > ).
< p > To change the checkbox's label use < a href = "qtableitem.html#setText" > setText< / a > (). The checkbox can be
checked and unchecked with < a href = "#setChecked" > setChecked< / a > () and its state retrieved
using < a href = "#isChecked" > isChecked< / a > ().
< p > To populate a table cell with a TQCheckTableItem use
< a href = "ntqtable.html#setItem" > TQTable::setItem< / a > ().
< p > TQCheckTableItems can be distinguished from < a href = "qtableitem.html" > TQTableItem< / a > s and
< a href = "qcombotableitem.html" > TQComboTableItem< / a > s using their Run Time Type Identification
(rtti) value.

< h3 class = fn > < a name = "TQCheckTableItem" > < / a > TQCheckTableItem::TQCheckTableItem ( < a href = "ntqtable.html" > TQTable< / a > * table, const < a href = "tqstring.html" > TQString< / a > & txt )
< / h3 >
Creates a TQCheckTableItem with an < a href = "qtableitem.html#EditType-enum" > EditType< / a > of < a href = "qtableitem.html#EditType-enum" > WhenCurrent< / a >
as a child of < em > table< / em > . The checkbox is initially unchecked and
its label is set to the string < em > txt< / em > .
< h3 class = fn > bool < a name = "isChecked" > < / a > TQCheckTableItem::isChecked () const
< / h3 >
Returns TRUE if the checkbox table item is checked; otherwise
returns FALSE.
< p > < p > See also < a href = "#setChecked" > setChecked< / a > ().
< h3 class = fn > int < a name = "rtti" > < / a > TQCheckTableItem::rtti () const< tt > [virtual]< / tt >
< / h3 >
< p > Returns 2.
< p > Make your derived classes return their own values for < a href = "#rtti" > rtti< / a > ()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.

< p > Reimplemented from < a href = "qtableitem.html#rtti" > TQTableItem< / a > .
< h3 class = fn > void < a name = "setChecked" > < / a > TQCheckTableItem::setChecked ( bool b )< tt > [virtual]< / tt >
< / h3 >
If < em > b< / em > is TRUE the checkbox is checked; if < em > b< / em > is FALSE the
checkbox is unchecked.
