Abstract
A method and system for framework clipping are disclosed. A user interface tree of widgets corresponding to widgets requiring clipping is traversed. For each encountered widget, layer allocation operations are performed which include selecting a current, previous, or next layer to which to allocate the widget and determining whether the selected layer can accommodate the widget, where a determination that the selected layer cannot accommodate the widget results in a bit from a stencil buffer being allocated to the selected layer. A value of the selected layer is incremented to account for the widget being allocated to the selected layer A stencil test mask is generated as a combination of value of the layers previous to a current layer. The stencil test mask is written to the stencil buffer, and the layer allocation operations are repeated for each remaining widget.
