  10     @class wxBitmapComboBox
  11
  12     A combobox that displays bitmap in front of the list items.
  13     It currently only allows using bitmaps of one size, and resizes itself
  14     so that a bitmap can be shown next to the text field.
  15
  16     @remarks
  17     While wxBitmapComboBox contains the wxComboBox API, but it might not actually
  18     be derived from that class. In fact, if the platform does not have a native
  19     implementation, wxBitmapComboBox will inherit from wxOwnerDrawnComboBox.
  20     You can determine if the implementation is generic by checking whether
  21     @c wxGENERIC_BITMAPCOMBOBOX is defined. Currently wxBitmapComboBox is
  22     implemented natively for MSW and GTK+.
  23
  24     @beginStyleTable
  25     @style{wxCB_READONLY}
  26            Creates a combobox without a text editor. On some platforms the
  27            control may appear very different when this style is used.
  28     @style{wxCB_SORT}
  29            Sorts the entries in the list alphabetically.
  30     @style{wxTE_PROCESS_ENTER}
  31            The control will generate the event wxEVT_COMMAND_TEXT_ENTER
  32            (otherwise pressing Enter key is either processed internally by the
  33            control or used for navigation between dialog controls).
  34            Windows only.
  35     @endStyleTable
  36
  37     @todo create wxCB_PROCESS_ENTER rather than reusing wxTE_PROCESS_ENTER!
  38
  39     @beginEventEmissionTable{wxCommandEvent}
  40     @event{EVT_COMBOBOX(id, func)}
  41            Process a @c wxEVT_COMMAND_COMBOBOX_SELECTED event, when an item on
  42            the list is selected.
  43     @event{EVT_TEXT(id, func)}
  44            Process a @c wxEVT_COMMAND_TEXT_UPDATED event, when the combobox text changes.
  45     @event{EVT_TEXT_ENTER(id, func)}
  46            Process a @c wxEVT_COMMAND_TEXT_ENTER event, when RETURN is pressed in
  47            the combobox.
