You can retrieve the id of the motif_display by sending the motif_display_id? message to any of the motif widgets. You should use this value to set the id of a motif_display instance. Then you can use the motif_display instance to set/get XmDisplay resources.
As a class, motif can be a parent to any top level widget in a user interface. It also controls the processing of the event loop.
motif_display new: mdisplay
id = [ motif motif_display_id?]
