Discussion

Use the CornerMask object to specify the corner radius for a component, and enable or disable the effect on a per-corner basis (topRight, topLeft, bottomRight, and bottomLeft). All corners are enabled by default. When you specify a border alongside a corner radius, the borders take into account the radius of the mask and are drawn within the unmasked area of the component.

You can use this object in ComponentStyle.
