<h2>Detailed Description</h2>

<p>The Q3CheckTableItem class provides checkboxes in Q3Tables.</p>

<p>A Q3CheckTableItem is a table item which looks and behaves like a checkbox. The advantage of using Q3CheckTableItems rather than real checkboxes is that a Q3CheckTableItem uses far less resources than a real checkbox would in a <a href="q3table.html">Q3Table</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 <i>looks</i> like a checkbox. Pixmaps may not be used in Q3CheckTableItems.</p>

<p>Q3CheckTableItem items have the edit type <tt>WhenCurrent</tt> (see <a href="q3tableitem.html#EditType-enum">EditType</a>).</p>

<p>To change the checkbox's label use <a href="q3checktableitem.html#setText">setText</a>(). The checkbox can be checked and unchecked with <a href="q3checktableitem.html#setChecked">setChecked</a>() and its state retrieved using <a href="q3checktableitem.html#isChecked">isChecked</a>().</p>

<p>To populate a table cell with a Q3CheckTableItem use <a href="q3table.html#setItem">Q3Table::setItem</a>().</p>

<p>Q3CheckTableItems can be distinguished from <a href="q3tableitem.html">Q3TableItem</a>s and <a href="q3combotableitem.html">Q3ComboTableItem</a>s using their Run Time Type Identification (rtti) value.</p>

<h2>Member Function Documentation</h2>

<h3 class="fn"><a name="Q3CheckTableItem"></a>Q3CheckTableItem::Q3CheckTableItem ( <a href="q3table.html">Q3Table</a> * <i>table</i>, const <a href="qstring.html">QString</a> & <i>txt</i> )</h3>

<p>Creates a <a href="q3checktableitem.html">Q3CheckTableItem</a> with an <a href="q3tableitem.html#EditType-enum">EditType</a> of <tt>WhenCurrent</tt> as a child of <i>table</i>. The checkbox is initially unchecked and its label is set to the string <i>txt</i>.</p>

<h3 class="fn"><a name="isChecked"></a>bool Q3CheckTableItem::isChecked () const</h3>

<p>Returns true if the checkbox table item is checked; otherwise returns false.</p>

<p>See also <a href="q3checktableitem.html#setChecked">setChecked</a>().</p>

<h3 class="fn"><a name="rtti"></a>int Q3CheckTableItem::rtti () const  <tt> [virtual]</tt></h3>

<p>Returns 2.</p>

<p>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.</p>

<p>Reimplemented from <a href="q3tableitem.html#rtti">Q3TableItem</a>.</p>

<p>See also <a href="q3tableitem.html#rtti">Q3TableItem::rtti</a>().</p>

<h3 class="fn"><a name="setChecked"></a>void Q3CheckTableItem::setChecked ( bool <i>b</i> )  <tt> [virtual]</tt></h3>

<p>If <i>b</i> is true the checkbox is checked; if <i>b</i> is false the checkbox is unchecked.</p>

<p>See also <a href="q3checktableitem.html#isChecked">isChecked</a>().</p>
