Attributes

Remarks

Sets r to the coordinates of the non-clipped area of this view relative to the top left corner of the view.

If the view is clipped on the left or top, the left and top coordinates are offset from 0 by the clipped amount. For example, if the view is off screen 50px on the left and 30px at the top, the left and top coordinates are 50 and 30 respectively.

If the view is clipped on the right or bottom, the right and bottom coordinates are reduced by the clipped amount. For example, if the view is off screen 40px on the right and 20px at the bottom, the right coordinate is the view width - 40, and the bottom coordinate is the view height - 20.
