1.10.5 Temporarily Freezing a Widget

At times, it is desirable to block a widget from being redisplayed for a short period of time. For example, during the process of inserting 100 items into a listbox, one usually don't want the list box be refreshed 100 times, but rather, be updated only once after the last item has been inserted. The EZ widget library provides a pair of routines to temporarily block a widget from being redisplayed.

void EZ_FreezeWidget(EZ_Widget *widget)

This function freeze a widget. A freezed widget will handle no events, including the Expose event.

void EZ_UnFreezeWidget(EZ_Widget *widget)

This function un-freeze a freezed widget. It has no effects if widget is not currently freezed.
