Instance Property

visibleRect

The portion of the view that is not clipped by its superviews.

Declaration

@property(readonly) NSRect visibleRect;

Discussion

Visibility, as reflected by this property, does not account for whether other view or window objects overlap the current view or whether the current view is installed in a window at all. This value of this property is NSZeroRect if the current view is effectively hidden.

During a printing operation the visible rectangle is further clipped to the page being imaged.
