  11     @wxheader{bmpcbox.h}
  12
  13     A combobox that displays bitmap in front of the list items.
  14     It currently only allows using bitmaps of one size, and resizes itself
  15     so that a bitmap can be shown next to the text field.
  16
  17     @beginStyleTable
  18     @style{wxCB_READONLY}:
  19            Creates a combobox without a text editor. On some platforms the
  20            control may appear very different when this style is used.
  21     @style{wxCB_SORT}:
  22            Sorts the entries in the list alphabetically.
  23     @style{wxTE_PROCESS_ENTER}:
  24            The control will generate the event wxEVT_COMMAND_TEXT_ENTER
  25            (otherwise pressing Enter key is either processed internally by the
  26            control or used for navigation between dialog controls). Windows
  27            only.
  28     @endStyleTable
  29
  30     @beginEventTable
  31     @event{EVT_COMBOBOX(id\, func)}:
  32            Process a wxEVT_COMMAND_COMBOBOX_SELECTED event, when an item on
  33            the list is selected.
  34     @event{EVT_TEXT(id\, func)}:
  35            Process a wxEVT_COMMAND_TEXT_UPDATED event, when the combobox text
  36            changes.
  37     @event{EVT_TEXT_ENTER(id\, func)}:
  38            Process a wxEVT_COMMAND_TEXT_ENTER event, when RETURN is pressed in
  39            the combobox.
