+ The menu may include the items with the following standard identifiers
+ (but may use arbitrary text and help strings and bitmaps for them):
+ - @c wxID_MDI_WINDOW_CASCADE
+ - @c wxID_MDI_WINDOW_TILE_HORZ
+ - @c wxID_MDI_WINDOW_TILE_VERT
+ - @c wxID_MDI_WINDOW_ARRANGE_ICONS
+ - @c wxID_MDI_WINDOW_PREV
+ - @c wxID_MDI_WINDOW_NEXT
+ All of which are handled by wxMDIParentFrame itself. If any other
+ commands are used in the menu, the derived frame should handle them.
