window style but this function also allows to do it by passing @NULL
pointer as @a menu.
+ 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.
+
This function is currently not available under OS X.
