<hr><a name="details"></a><h2>Detailed Description</h2>
The TQListBoxItem class is the base class of all list box items.
<p> This class is an abstract base class used for all list box items.
If you need to insert customized items into a <a href="ntqlistbox.html">TQListBox</a> you must
inherit this class and reimplement <a href="#paint">paint</a>(), <a href="#height">height</a>() and <a href="#width">width</a>().
<p> <p>See also <a href="ntqlistbox.html">TQListBox</a>.
<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="TQListBoxItem"></a>TQListBoxItem::TQListBoxItem ( <a href="ntqlistbox.html">TQListBox</a> * listbox = 0 )
</h3>
Constructs an empty list box item in the list box <em>listbox</em>.
<h3 class=fn><a name="TQListBoxItem-2"></a>TQListBoxItem::TQListBoxItem ( <a href="ntqlistbox.html">TQListBox</a> * listbox, <a href="qlistboxitem.html">TQListBoxItem</a> * after )
</h3>
Constructs an empty list box item in the list box <em>listbox</em> and
inserts it after the item <em>after</em> or at the beginning if <em>after</em>
is 0.
<h3 class=fn><a name="~TQListBoxItem"></a>TQListBoxItem::~TQListBoxItem ()<tt> [virtual]</tt>
</h3>
Destroys the list box item.
<h3 class=fn>bool <a name="current"></a>TQListBoxItem::current () const
</h3>
<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p>
<h3 class=fn>int <a name="height"></a>TQListBoxItem::height ( const <a href="ntqlistbox.html">TQListBox</a> * lb ) const<tt> [virtual]</tt>
</h3>
<p> Implement this function to return the height of your item. The <em>lb</em> parameter is the same as <a href="#listBox">listBox</a>() and is provided for
convenience and compatibility.
<p> The default implementation returns
<a href="ntqapplication.html#globalStrut">TQApplication::globalStrut</a>()'s height.
<p> <p>See also <a href="#paint">paint</a>() and <a href="#width">width</a>().
<p>Reimplemented in <a href="qlistboxtext.html#height">TQListBoxText</a> and <a href="qlistboxpixmap.html#height">TQListBoxPixmap</a>.
<h3 class=fn>bool <a name="isCurrent"></a>TQListBoxItem::isCurrent () const
</h3>
Returns TRUE if the item is the current item; otherwise returns
FALSE.
<p> <p>See also <a href="ntqlistbox.html#currentItem-prop">TQListBox::currentItem</a>, <a href="ntqlistbox.html#item">TQListBox::item</a>(), and <a href="#isSelected">isSelected</a>().
<h3 class=fn>bool <a name="isSelectable"></a>TQListBoxItem::isSelectable () const
</h3>
Returns TRUE if this item is selectable (the default); otherwise
returns FALSE.
<p> <p>See also <a href="#setSelectable">setSelectable</a>().
<h3 class=fn>bool <a name="isSelected"></a>TQListBoxItem::isSelected () const
</h3>
<p> Returns TRUE if the item is selected; otherwise returns FALSE.
<p> <p>See also <a href="ntqlistbox.html#isSelected">TQListBox::isSelected</a>() and <a href="#isCurrent">isCurrent</a>().
<p>Example: <a href="listboxcombo-example.html#x1409">listboxcombo/listboxcombo.cpp</a>.
<h3 class=fn><a href="ntqlistbox.html">TQListBox</a> * <a name="listBox"></a>TQListBoxItem::listBox () const
</h3>
Returns a pointer to the list box containing this item.
<h3 class=fn><a href="qlistboxitem.html">TQListBoxItem</a> * <a name="next"></a>TQListBoxItem::next () const
</h3>
Returns the item that comes after this in the list box. If this is
the last item, 0 is returned.
<p> <p>See also <a href="#prev">prev</a>().
<h3 class=fn>void <a name="paint"></a>TQListBoxItem::paint ( <a href="tqpainter.html">TQPainter</a> * p )<tt> [pure virtual protected]</tt>
</h3>
<p> Implement this function to draw your item. The painter, <em>p</em>, is
already open for painting.
<p> <p>See also <a href="#height">height</a>() and <a href="#width">width</a>().
<p>Example: <a href="listboxcombo-example.html#x1410">listboxcombo/listboxcombo.cpp</a>.
<p>Reimplemented in <a href="qlistboxtext.html#paint">TQListBoxText</a> and <a href="qlistboxpixmap.html#paint">TQListBoxPixmap</a>.
<h3 class=fn>const <a href="tqpixmap.html">TQPixmap</a> * <a name="pixmap"></a>TQListBoxItem::pixmap () const<tt> [virtual]</tt>
</h3>
Returns the pixmap associated with the item, or 0 if there isn't
one.
<p> The default implementation returns 0.
<p>Example: <a href="listboxcombo-example.html#x1411">listboxcombo/listboxcombo.cpp</a>.
<p>Reimplemented in <a href="qlistboxpixmap.html#pixmap">TQListBoxPixmap</a>.
<h3 class=fn><a href="qlistboxitem.html">TQListBoxItem</a> * <a name="prev"></a>TQListBoxItem::prev () const
</h3>
Returns the item which comes before this in the list box. If this
is the first item, 0 is returned.
<p> <p>See also <a href="#next">next</a>().
<h3 class=fn>int <a name="rtti"></a>TQListBoxItem::rtti () const<tt> [virtual]</tt>
</h3>
Returns 0.
<p> Make your derived classes return their own values for <a href="#rtti">rtti</a>(), and
you can distinguish between listbox items. You should use values
greater than 1000 preferably a large random number, to allow for
extensions to this class.
<h3 class=fn>bool <a name="selected"></a>TQListBoxItem::selected () const
</h3>
<b>This function is obsolete.</b> It is provided to keep old source working. We strongly advise against using it in new code.
<p>
<h3 class=fn>void <a name="setCustomHighlighting"></a>TQListBoxItem::setCustomHighlighting ( bool b )<tt> [protected]</tt>
</h3>
Defines whether the list box item is responsible for drawing
itself in a highlighted state when being selected.
<p> If <em>b</em> is FALSE (the default), the list box will draw some
default highlight indicator before calling <a href="#paint">paint</a>().
<p> <p>See also <a href="#selected">selected</a>() and <a href="#paint">paint</a>().
<h3 class=fn>void <a name="setSelectable"></a>TQListBoxItem::setSelectable ( bool b )
</h3>
If <em>b</em> is TRUE (the default) then this item can be selected by
the user; otherwise this item cannot be selected by the user.
<p> <p>See also <a href="#isSelectable">isSelectable</a>().
<h3 class=fn>void <a name="setText"></a>TQListBoxItem::setText ( const <a href="tqstring.html">TQString</a> & text )<tt> [virtual protected]</tt>
</h3>
<p> Sets the text of the TQListBoxItem to <em>text</em>. This <em>text</em> is also
used for sorting. The text is not shown unless explicitly drawn in
<a href="#paint">paint</a>().
<p> <p>See also <a href="#text">text</a>().
<h3 class=fn><a href="tqstring.html">TQString</a> <a name="text"></a>TQListBoxItem::text () const<tt> [virtual]</tt>
</h3>
Returns the text of the item. This text is also used for sorting.
<p> <p>See also <a href="#setText">setText</a>().
<p>Example: <a href="listboxcombo-example.html#x1412">listboxcombo/listboxcombo.cpp</a>.
<h3 class=fn>int <a name="width"></a>TQListBoxItem::width ( const <a href="ntqlistbox.html">TQListBox</a> * lb ) const<tt> [virtual]</tt>
</h3>
<p> Reimplement this function to return the width of your item. The <em>lb</em> parameter is the same as <a href="#listBox">listBox</a>() and is provided for
convenience and compatibility.
<p> The default implementation returns
<a href="ntqapplication.html#globalStrut">TQApplication::globalStrut</a>()'s width.
<p> <p>See also <a href="#paint">paint</a>() and <a href="#height">height</a>().
