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="tqcombotableitem.html">TQComboTableItem</a>s using their Run Time Type Identification
(rtti) value.

<hr><h2>Member Function Documentation</h2>
<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> <p>See also <a href="qtableitem.html#rtti">TQTableItem::rtti</a>().
<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.
<p> <p>See also <a href="#isChecked">isChecked</a>().
