112The "V" in wxVListBox stands for both "virtual" because it can have an
113unlimited number of items since it doesn't store them itself, and
114"variable" since items can vary in height. It has much the same
115interface as wxListBox and also emits the same events so you can use
116the same EVT_LISTBOX function to connect a handler.

119The wx.HtmlListBox derives from wx.VListBox, but draws each item itself
120as a wx.HtmlCell. This means that you just need to provide a snippet
3628e088
RD
121of HTML for each item when requested.
