Detailed Description
Direct3D9 RenderTarget that represents a screen viewport.
Constructor & Destructor Documentation
| CEGUI::Direct3D9ViewportTarget::Direct3D9ViewportTarget | ( | Direct3D9Renderer & | owner, |
| const Rect & | area | ||
| ) |
Construct a Direct3D9ViewportTarget that uses the specified Rect as it's initial area.
- Parameters
-
area Rect object describing the initial viewport area that should be used for the RenderTarget.

Return whether the RenderTarget is an implementation that caches actual rendered imagery.
Typically it is expected that texture based RenderTargets would return true in response to this call. Other types of RenderTarget, like view port based targets, will more likely return false.
- Returns
- true if the RenderTarget does cache rendered imagery.
- false if the RenderTarget does not cache rendered imagery.
Implements CEGUI::RenderTarget.
