Class VisualBase

Definition

Namespace:

Tizen.NUI

Assembly:

Tizen.NUI.dll

Sets whether the actor should be focusable by keyboard navigation.
Visuals reuse geometry, shader etc. across controls. They ensure that the renderer and texture sets exist only when control is on window.
Each visual also responds to actor size and color change, and provides clipping at the renderer level.
