abstract member GetChildVisibleRect : Android.Views.View * Android.Graphics.Rect * Android.Graphics.Point -> boolParameters
- child
- View
A child View, whose rectangular visible region we want to compute
- r
- Rect
The input rectangle, defined in the child coordinate system. Will be overwritten to contain the resulting visible rectangle, expressed in global (root) coordinates
- offset
- Point
The input coordinates of a point, defined in the child coordinate system.
As with the r parameter, this will be overwritten to contain the global (root)
coordinates of that point.
A null value is valid (in case you are not interested in this result)
Returns
true if the resulting rectangle is not empty, false otherwise
- Attributes
Remarks
Compute the visible part of a rectangular region defined in terms of a child view's coordinates.
Returns the clipped visible part of the rectangle r, defined in the child's local coordinate system. r is modified by this method to contain the result, expressed in the global (root) coordinate system.
The resulting rectangle is always axis aligned. If a rotation is applied to a node in the View hierarchy, the result is the axis-aligned bounding box of the visible rectangle.
