ModifyProp

Modify the current parameters of a proportional gadget.

Modifies the parameters of the specified proportional gadget. The gadget's internal state is then recalculated and the imagery is redisplayed in the window or requester that contains the gadget.

The requester variable can point to a requester structure. If the gadget has the GTYP_REQGADGET flag set, the gadget is in a requester and the window pointer must point to the window of the requester. If this is not the gadget of a requester, the requester argument may be NULL.

NOTE:

this function causes all gadgets from the proportional

gadget to the end of the gadget list to be refreshed, for reasons of compatibility. For more refined display updating, use NewModifyProp().

New for V36: ModifyProp() refreshing consists of redrawing gadgets completely. NewModifyProp() has changed this behavior (see NewModifyProp()).
