49The QCheckTableItem class provides checkboxes in QTables.
50
51<p>
52
53<p> A QCheckTableItem is a table item which looks and behaves like a
54checkbox. The advantage of using QCheckTableItems rather than real
55checkboxes is that a QCheckTableItem uses far less resources than
56a real checkbox would in a <a href="qtable.html">QTable</a>. When the cell has the focus
57it displays a real checkbox which the user can interact with. When
58the cell does not have the focus the cell <em>looks</em> like a
59checkbox. Pixmaps may not be used in QCheckTableItems.
60<p> QCheckTableItem items have the edit type <a href="qtableitem.html#EditType-enum">WhenCurrent</a> (see
61<a href="qtableitem.html#EditType-enum">EditType</a>).
62<p> To change the checkbox's label use <a href="qtableitem.html#setText">setText</a>(). The checkbox can be
63checked and unchecked with <a href="#setChecked">setChecked</a>() and its state retrieved
64using <a href="#isChecked">isChecked</a>().
65<p> To populate a table cell with a QCheckTableItem use
66<a href="qtable.html#setItem">QTable::setItem</a>().
67<p> QCheckTableItems can be distinguished from <a href="qtableitem.html">QTableItem</a>s and
68<a href="qcombotableitem.html">QComboTableItem</a>s using their Run Time Type Identification
69(rtti) value.

75</h3>
76Creates a QCheckTableItem with an <a href="qtableitem.html#EditType-enum">EditType</a> of <a href="qtableitem.html#EditType-enum">WhenCurrent</a>
77as a child of <em>table</em>. The checkbox is initially unchecked and
78its label is set to the string <em>txt</em>.
79
80<h3 class=fn>bool <a name="isChecked"></a>QCheckTableItem::isChecked () const
81</h3>
82Returns TRUE if the checkbox table item is checked; otherwise
83returns FALSE.
84<p> <p>See also <a href="#setChecked">setChecked</a>().

86<h3 class=fn>int <a name="rtti"></a>QCheckTableItem::rtti () const<tt> [virtual]</tt>
87</h3>
88
89<p> Returns 2.
90<p> Make your derived classes return their own values for <a href="#rtti">rtti</a>()to
91distinguish between different table item subclasses. You should
92use values greater than 1000, preferably a large random number, to
93allow for extensions to this class.
