Use
The syntax of this call will return a windows visible state.
Notes
“Visible area” gives the window in screen co-ordinates. “Scroll offset” gives the top-left hand corner of the window in user co-ordinates. It is only an offset when the top-left corner of the extent is (0,0) in user co-ordinates.
Another syntax form of this call can be used to cause information relating to a specific window and its parent window to be returned. This, however, requires a Window Manager with nested window capability.
