RefreshGList -- Refresh (redraw) a chosen number of gadgets.
RefreshGList( Gadgets, Window, Requester, NumGad )
A0 A1 A2 D0
VOID RefreshGList( struct Gadget *, struct Window *,
struct Requester *, WORD );
Refreshes (redraws) gadgets in the gadget list starting
from the specified gadget. At most NumGad gadgets are redrawn.
If NumGad is -1, all gadgets until a terminating NULL value
in the NextGadget field is found will be refreshed, making this
routine a superset of RefreshGadgets().
The Requester parameter can point to a Requester structure. If
the first gadget in the list has the GTYP_REQGADGET flag set, the
gadget list refers to gadgets in a requester and the pointer
must necessarily point to a window. If these are not the gadgets
of a requester, the requester argument may be NULL.
Be sure to see the RefreshGadgets() function description, as this
function is simply an extension of that.
Gadgets = pointer to the first in the list of gadgets wanting
refreshment
Window = pointer to the window containing the gadget or its requester
Requester = pointer to a requester (ignored if Gadget is not attached
to a Requester).
NumGad = maximum number of gadgets to be refreshed. A value of -1
will cause all gadgets to be refreshed from gadget to the
end of the list. A value of -2 will also do this, but if 'Gadgets'
points to a Requester Gadget (GTYP_REQGADGET) ALL gadgets in the
requester will be refreshed (this is a mode compatible with v1.1
RefreshGadgets().)
None
