Instance Method

gState

Returns the identifier for the view’s graphics state object, or 0 if the view doesn’t have a graphics state object.

Declaration

- (NSInteger)gState;

Discussion

A view object’s graphics state object is recreated from scratch whenever the view is focused, unless the allocateGState method has been invoked. So if the view hasn’t been focused or hasn’t received the allocateGState message, this method returns 0.

Although applications rarely need to use the value returned by gState, it can be passed to the few methods that take an object identifier as a parameter.
