<hr>

|
|
|
The "V" in wxVListBox stands for both "virtual" because it can have an
|
|
unlimited number of items since it doesn't store them itself, and
|
|
"variable" since items can vary in height. It has much the same
|
|
interface as wxListBox and also emits the same events so you can use
|
|
the same EVT_LISTBOX function to connect a handler.
|
|
<p>
|
|
|
|
The wxHtmlListBox derives from wxVListBox, but draws each item itself
|
|
as a wxHtmlCell. This means that you just need to provide a snippet
|
|
of HTML for each item when requested.
