Class VisualBase

Definition

Namespace:: Tizen.NUI

Assembly:: Tizen.NUI.dll

API Level:: 3

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.

GetNaturalSize(Size2D)

Returns the natural size of the visual.
Deriving classes stipulate the natural size and by default a visual has a zero natural size.
A visual may not actually have a natural size until it has been placed on window and acquired all it's resources.
