Members| Member | Description |
|---|---|
| NSViewLayerContentsRedrawNever | Leave the layer's contents alone. Never mark the layer as needing display, or draw the view's contents to the layer. This is how developer created layers (layer-hosting views) are treated. Available in Mac OS X v10.6 and later. |
| NSViewLayerContentsRedrawOnSetNeedsDisplay | Any of the setNeedsDisplay... methods sent to the view will cause the view redraw the affected layer parts by invoking the view's drawRect:, but neither the layer or the view are marked as needing display when the view's size changes. Available in Mac OS X v10.6 and later. |
| NSViewLayerContentsRedrawDuringViewResize | Resize the view’s backing-layer and redraw the view to the layer when the view's size changes. If the resize is animated, AppKit will drive the resize animation itself and will do this resize and redraw at each step of the animation. Affected parts of the layer will also be redrawn when the view is marked as needing display. This mode is a superset of NSViewLayerContentsRedrawOnSetNeedsDisplay. This is the way that layer-backed views are currently treated. Available in Mac OS X v10.6 and later. |
| NSViewLayerContentsRedrawBeforeViewResize | Resize the layer and redraw the view to the layer when the view's size changes. This will be done just once at the beginning of a resize animation, not at each frame of the animation. Affected parts of the layer will also be redrawn when the view is marked as needing display. This mode is a superset of NSViewLayerContentsRedrawOnSetNeedsDisplay. Available in Mac OS X v10.6 and later. |
