|
|
||
|
|
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="qlistbox.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="qlistbox.html">TQListBox</a>.
