<hr><a name="details"></a><h2>Detailed Description</h2>



<p> The QListBoxItem 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="qlistbox.html">QListBox</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="qlistbox.html">QListBox</a> and <a href="advanced.html">Advanced Widgets</a>.

<hr><h2>Member Function Documentation</h2>
<h3 class=fn><a name="QListBoxItem"></a>QListBoxItem::QListBoxItem ( <a href="qlistbox.html">QListBox</a>&nbsp;*&nbsp;listbox = 0 )
</h3>
Constructs an empty list box item in the list box <em>listbox</em>.

<h3 class=fn><a name="QListBoxItem-2"></a>QListBoxItem::QListBoxItem ( <a href="qlistbox.html">QListBox</a>&nbsp;*&nbsp;listbox, <a href="qlistboxitem.html">QListBoxItem</a>&nbsp;*&nbsp;after )
</h3>
Constructs an empty list box item in the list box <em>listbox</em> and
inserts it after the item <em>after</em>. If <em>after</em> is 0, the item
is inserted at the beginning.

<h3 class=fn><a name="~QListBoxItem"></a>QListBoxItem::~QListBoxItem ()<tt> [virtual]</tt>
</h3>
Destroys the list box item.

<h3 class=fn>bool <a name="current"></a>QListBoxItem::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This function is obsolete.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>QListBoxItem::height ( const&nbsp;<a href="qlistbox.html">QListBox</a>&nbsp;*&nbsp;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> <p>See also <a href="#paint">paint</a>() and <a href="#width">width</a>().

<p>Reimplemented in <a href="qlistboxtext.html#height">QListBoxText</a> and <a href="qlistboxpixmap.html#height">QListBoxPixmap</a>.
<h3 class=fn>bool <a name="isCurrent"></a>QListBoxItem::isCurrent () const
</h3>
Returns TRUE if the item is the current item; otherwise returns FALSE.
<p> <p>See also <a href="qlistbox.html#currentItem-prop">QListBox::currentItem</a>, <a href="qlistbox.html#item">QListBox::item</a>() and <a href="#isSelected">isSelected</a>().

<h3 class=fn>bool <a name="isSelectable"></a>QListBoxItem::isSelectable () const
</h3>
Returns TRUE if this item is selectable; otherwise returns FALSE.
<p> <p>See also <a href="#setSelectable">setSelectable</a>().

<h3 class=fn>bool <a name="isSelected"></a>QListBoxItem::isSelected () const
</h3> 
Returns TRUE if the item is selected; otherwise returns FALSE.
<p> <p>See also <a href="qlistbox.html#isSelected">QListBox::isSelected</a>() and <a href="#isCurrent">isCurrent</a>().

<p>Example: <a href="listboxcombo-example.html#x1249">listboxcombo/listboxcombo.cpp</a>.
<h3 class=fn><a href="qlistbox.html">QListBox</a>&nbsp;* <a name="listBox"></a>QListBoxItem::listBox () const
</h3> Returns a pointer to the list box containing this item.

<h3 class=fn><a href="qlistboxitem.html">QListBoxItem</a>&nbsp;* <a name="next"></a>QListBoxItem::next () const
</h3>  Returns the item that comes after this in the list box. If this is
the last item, a null pointer is returned.
<p> <p>See also <a href="#prev">prev</a>().

<h3 class=fn>void <a name="paint"></a>QListBoxItem::paint ( <a href="qpainter.html">QPainter</a>&nbsp;*&nbsp;p )<tt> [pure virtual protected]</tt>
</h3>

<p> Implement this function to draw your item.  You will
need to pass the <a href="qpainter.html">QPainter</a> that will draw the item in <em>p</em>.
<p> <p>See also <a href="#height">height</a>() and <a href="#width">width</a>().

<p>Example: <a href="listboxcombo-example.html#x1250">listboxcombo/listboxcombo.cpp</a>.
<p>Reimplemented in <a href="qlistboxtext.html#paint">QListBoxText</a> and <a href="qlistboxpixmap.html#paint">QListBoxPixmap</a>.
<h3 class=fn>const&nbsp;<a href="qpixmap.html">QPixmap</a>&nbsp;* <a name="pixmap"></a>QListBoxItem::pixmap () const<tt> [virtual]</tt>
</h3>
Returns the pixmap associated with the item, if any.
<p> The default implementation returns a null pointer.

<p>Example: <a href="listboxcombo-example.html#x1251">listboxcombo/listboxcombo.cpp</a>.
<p>Reimplemented in <a href="qlistboxpixmap.html#pixmap">QListBoxPixmap</a>.
<h3 class=fn><a href="qlistboxitem.html">QListBoxItem</a>&nbsp;* <a name="prev"></a>QListBoxItem::prev () const
</h3>  Returns the item which comes before this in the list box. If this is
the first item, a null pointer is returned.
<p> <p>See also <a href="#next">next</a>().

<h3 class=fn>int <a name="rtti"></a>QListBoxItem::rtti () const<tt> [virtual]</tt>
</h3> Returns 0.
<p> Although often frowned upon by purists, Run Time Type Identification
is very useful in this case, as it allows a <a href="qlistbox.html">QListBox</a> to be an
efficient indexed storage mechanism.
<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>QListBoxItem::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>QListBoxItem::setCustomHighlighting ( bool&nbsp;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>QListBoxItem::setSelectable ( bool&nbsp;b )
</h3>
If <em>b</em> is TRUE 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>QListBoxItem::setText ( const&nbsp;<a href="qstring.html">QString</a>&nbsp;&amp;&nbsp;text )<tt> [virtual protected]</tt>
</h3>

<p> Sets the text of the QListBoxItem 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="qstring.html">QString</a> <a name="text"></a>QListBoxItem::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#x1252">listboxcombo/listboxcombo.cpp</a>.
<h3 class=fn>int <a name="width"></a>QListBoxItem::width ( const&nbsp;<a href="qlistbox.html">QListBox</a>&nbsp;*&nbsp;lb ) const<tt> [virtual]</tt>
</h3>

<p> Implement 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> <p>See also <a href="#paint">paint</a>() and <a href="#height">height</a>().

<p>Reimplemented in <a href="qlistboxtext.html#width">QListBoxText</a> and <a href="qlistboxpixmap.html#width">QListBoxPixmap</a>.
