| <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 wx.HtmlListBox derives from wx.VListBox, but draws each item itself
 | |
| as a wx.HtmlCell.  This means that you just need to provide a snippet
 | |
| of HTML for each item when requested.
