|
|
|
|
|
|
The QCheckTableItem class provides checkboxes in QTables.
|
|
|
|
<p>
|
|
|
|
<p> 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 <a href="qtable.html">QTable</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 QCheckTableItems.
|
|
<p> QCheckTableItem 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 QCheckTableItem use
|
|
<a href="qtable.html#setItem">QTable::setItem</a>().
|
|
<p> QCheckTableItems can be distinguished from <a href="qtableitem.html">QTableItem</a>s and
|
|
<a href="qcombotableitem.html">QComboTableItem</a>s using their Run Time Type Identification
|
|
(rtti) value.

|
|
<h3 class=fn><a name="QCheckTableItem"></a>QCheckTableItem::QCheckTableItem ( <a href="qtable.html">QTable</a> * table, const <a href="qstring.html">QString</a> & txt )
|
|
</h3>
|
|
Creates a QCheckTableItem 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>QCheckTableItem::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>QCheckTableItem::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> <p>See also <a href="qtableitem.html#rtti">QTableItem::rtti</a>().
|
|
|
|
<p>Reimplemented from <a href="qtableitem.html#rtti">QTableItem</a>.
|
|
<h3 class=fn>void <a name="setChecked"></a>QCheckTableItem::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.
|
|
<p> <p>See also <a href="#isChecked">isChecked</a>().
