32 class ControlRenderer;
36 * ControlRenderer provides renderer for rendering the controls. A control may have multiple ControlRenders.
37 * ControlRenderers reuses geometry, shader etc. across controls and manages the renderer and material to exist only when control is on-stage.
38 * It also responds to actor size and color change, and provides the clipping at the renderer level.
39 * Note: The control renderer responds to the the Actor::COLOR by blending it with the 'Multiply' operator.

46 * @brief Create an empty ControlRenderer Handle
53 * This is non-virtual since derived Handle types must not contain data or virtual methods.
58 * @brief This copy constructor is required for (smart) pointer semantics.
60 * @param[in] handle A reference to the copied handle.

81 * The contents of the renderer will not be visible outside this rectangular.
83 * @param [in] clipRect The clipping rectangular.

88 * Reposition this renderer with a 2D offset.
90 * @param[in] offset The offset to reposition the renderer.

95 * Set the depth index of this renderer.
96 * Depth-index controls draw-order for overlapping renderers.
97 * Renderer with higher depth indices are rendered in front of other renderer with smaller values
99 * @param[in] depthIndex The depth index of this renderer.

104 * Renderer only exists when control is on stage.
105 * This function should be called when the control put on stage.
107 * @param[in] actor The actor applying this renderer.
109 void SetOnStage( Actor& actor );
112 * Renderer is destroyed when control is off stage.
113 * This function should be called when the control removes from stage
115 * @param[in] actor The actor applying this renderer.
