| | 110 | The "V" in wxVListBox stands for both "virtual" because it can have an |
| | 111 | unlimited number of items since it doesn't store them itself, and |
| | 112 | "variable" since items can vary in height. It has much the same |
| | 113 | interface as wxListBox and also emits the same events so you can use |
| | 114 | the same EVT_LISTBOX function to connect a handler. |
| | 115 | <p> |
| | 116 | |
| | 117 | The wx.HtmlListBox derives from wx.VListBox, but draws each item itself |
| | 118 | as a wx.HtmlCell. This means that you just need to provide a snippet |
| | 119 | of HTML for each item when requested. |
