Inputs:
(continued)
MBF_NO_DRAWTOP
Setup the menu-draw structure and return a handle to it
but do not draw the menu (caller must call
MenuOn
to
draw it).
NOTE:
If both MAX_MENU_WIDTH and MBF_HMENU are set, the first
parameter after
Flags
is the maximum menu width and the
second parameter is the handle to a dynamic menu.
Outputs:
HANDLE of the newly created menu-draw structure. (Note that this handle
is passed to menu routines like
MenuCheck
,
MenuKey
,
MenuOn
,
MenuTopStat
.) It is separate from the handle returned by
MenuNew
for
dynamic menus. H_NULL is returned if there is not enough memory to
create the new structure.
Assumptions:
None
Side Effects:
May cause heap compression.
