It is possible, but only for a widget base. Look at the IDL help for
WIDGET_CONTROL and the keyword MAP.

Basically, you can call WIDGET_CONTROL, id, MAP=0 for any widget, but
all widgets in the same base will be unmapped. Just create a new base
which only contains the widgets you want to be able to map and un-map.
