<hr><a name="details"></a><h2>Detailed Description</h2>
The QCheckListItem class provides checkable list view items.
<p> QCheckListItems are used in <a href="qlistview.html">QListView</a>s to provide
<a href="qlistviewitem.html">QListViewItem</a>s that are checkboxes, radio buttons or
controllers.
<p> Checkbox and controller check list items may be inserted at any
level in a list view. Radio button check list items must be children
of a controller check list item.
<p> The item can be checked or unchecked with <a href="#setOn">setOn</a>(). Its type can be
retrieved with <a href="#type">type</a>() and its text retrieved with <a href="#text">text</a>().

<hr><h2>Member Type Documentation</h2>
<h3 class=fn><a name="Type-enum"></a>QCheckListItem::Type</h3>
<p> This enum type specifies a QCheckListItem's type:
<ul>
<li><tt>QCheckListItem::RadioButton</tt>
<li><tt>QCheckListItem::CheckBox</tt>
<li><tt>QCheckListItem::Controller</tt>
</ul>
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QCheckListItem"></a>QCheckListItem::QCheckListItem ( <a href="qchecklistitem.html">QCheckListItem</a> * parent, const <a href="qstring.html">QString</a> & text, <a href="qchecklistitem.html#Type-enum">Type</a> tt = Controller )
</h3>
Constructs a checkable item with parent <em>parent</em>, text <em>text</em> and type
<em>tt</em>. Note that a RadioButton must be the child of a Controller,
otherwise it will not toggle.
<h3 class=fn><a name="QCheckListItem-2"></a>QCheckListItem::QCheckListItem ( <a href="qlistviewitem.html">QListViewItem</a> * parent, const <a href="qstring.html">QString</a> & text, <a href="qchecklistitem.html#Type-enum">Type</a> tt = Controller )
</h3>
Constructs a checkable item with parent <em>parent</em>, text <em>text</em> and type
<em>tt</em>. Note that this item must <em>not</em> be a RadioButton. Radio
buttons must be children of a Controller.
<h3 class=fn><a name="QCheckListItem-3"></a>QCheckListItem::QCheckListItem ( <a href="qlistview.html">QListView</a> * parent, const <a href="qstring.html">QString</a> & text, <a href="qchecklistitem.html#Type-enum">Type</a> tt = Controller )
</h3>
Constructs a checkable item with parent <em>parent</em>, text <em>text</em> and type
<em>tt</em>. Note that <em>tt</em> must <em>not</em> be RadioButton. Radio
buttons must be children of a Controller.
<p>
<h3 class=fn><a name="QCheckListItem-4"></a>QCheckListItem::QCheckListItem ( <a href="qlistviewitem.html">QListViewItem</a> * parent, const <a href="qstring.html">QString</a> & text, const <a href="qpixmap.html">QPixmap</a> & p )
</h3>
Constructs a Controller item with parent <em>parent</em>, text <em>text</em> and pixmap
<em>p</em>.
<h3 class=fn><a name="QCheckListItem-5"></a>QCheckListItem::QCheckListItem ( <a href="qlistview.html">QListView</a> * parent, const <a href="qstring.html">QString</a> & text, const <a href="qpixmap.html">QPixmap</a> & p )
</h3>
Constructs a Controller item with parent <em>parent</em>, text <em>text</em> and pixmap
<em>p</em>.
<h3 class=fn><a name="~QCheckListItem"></a>QCheckListItem::~QCheckListItem ()
</h3> Destroys the item, deleting all its children, freeing up all
allocated resources.
<h3 class=fn>void <a name="activate"></a>QCheckListItem::activate ()<tt> [virtual protected]</tt>
</h3>
Toggle check box or set radio button to on.
<p>Reimplemented from <a href="qlistviewitem.html#activate">QListViewItem</a>.
<h3 class=fn>bool <a name="isOn"></a>QCheckListItem::isOn () const
</h3>
Returns TRUE if the item is toggled on; otherwise returns FALSE.
<h3 class=fn>void <a name="paintCell"></a>QCheckListItem::paintCell ( <a href="qpainter.html">QPainter</a> * p, const <a href="qcolorgroup.html">QColorGroup</a> & cg, int column, int width, int align )<tt> [virtual]</tt>
</h3> Paints the item using the painter <em>p</em> and the color group <em>cg</em>.
The item is in column <em>column</em>, has width <em>width</em> and is aligned
<em>align</em>. (See Qt::AlignmentFlags for valid alignments.)
<p>Reimplemented from <a href="qlistviewitem.html#paintCell">QListViewItem</a>.
<h3 class=fn>void <a name="paintFocus"></a>QCheckListItem::paintFocus ( <a href="qpainter.html">QPainter</a> * p, const <a href="qcolorgroup.html">QColorGroup</a> & cg, const <a href="qrect.html">QRect</a> & r )<tt> [virtual]</tt>
</h3> Draws the focus rectangle <em>r</em> using the color group <em>cg</em> on
the painter <em>p</em>.
<p>Reimplemented from <a href="qlistviewitem.html#paintFocus">QListViewItem</a>.
<h3 class=fn>int <a name="rtti"></a>QCheckListItem::rtti () const<tt> [virtual]</tt>
</h3>
<p> Returns 1.
<p> Make your derived classes return their own values for <a href="#rtti">rtti</a>(), and
you can distinguish between listview items. 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="qlistviewitem.html#rtti">QListViewItem</a>.
<h3 class=fn>void <a name="setOn"></a>QCheckListItem::setOn ( bool b )<tt> [virtual]</tt>
</h3>
Sets the button on if <em>b</em> is TRUE, otherwise sets it off. Maintains
radio button exclusivity.
<h3 class=fn>void <a name="stateChange"></a>QCheckListItem::stateChange ( bool )<tt> [virtual protected]</tt>
</h3>
This virtual function is called when the item changes its on/off state.
<h3 class=fn><a href="qstring.html">QString</a> <a name="text"></a>QCheckListItem::text () const
</h3>
<p> Returns the text of the item.
<h3 class=fn>void <a name="turnOffChild"></a>QCheckListItem::turnOffChild ()<tt> [protected]</tt>
</h3>
If this is a Controller that has RadioButton children, turn off the
child that is on.
<h3 class=fn><a href="qchecklistitem.html#Type-enum">Type</a> <a name="type"></a>QCheckListItem::type () const
