Detailed Description

wxSimpleHtmlListBox is an implementation of wxHtmlListBox which shows HTML content in the listbox rows.

Unlike wxHtmlListBox, this is not an abstract class and thus it has the advantage that you can use it without deriving your own class from it. However, it also has the disadvantage that this is not a virtual control and thus it's not well-suited for those cases where you need to show a huge number of items: every time you add/insert a string, it will be stored internally and thus will take memory.

The interface exposed by wxSimpleHtmlListBox fully implements the wxControlWithItems interface, thus you should refer to wxControlWithItems's documentation for the API reference for adding/removing/retrieving items in the listbox. Also note that the wxVListBox::SetItemCount function is protected in wxSimpleHtmlListBox's context so that you cannot call it directly, wxSimpleHtmlListBox will do it for you.

Note: in case you need to append a lot of items to the control at once, make sure to use the Append(const wxArrayString&) function.

Thus the only difference between a wxListBox and a wxSimpleHtmlListBox is that the latter stores strings which can contain HTML fragments (see the list of tags supported by wxHTML).

Note that the HTML strings you fetch to wxSimpleHtmlListBox should not contain the <html> or <body> tags.

Styles

This class supports the following styles:

wxHLB_DEFAULT_STYLE:
The default style: wxBORDER_SUNKEN
wxHLB_MULTIPLE:
Multiple-selection list: the user can toggle multiple items on and off.

A wxSimpleHtmlListBox emits the same events used by wxListBox and by wxHtmlListBox.

Events emitted by this class

EVT_HTML_CELL_CLICKED(id, func):
A wxHtmlCell was clicked. See wxHtmlCellEvent.
EVT_HTML_CELL_HOVER(id, func):
