Detailed Description

CEGUI::RenderTarget that targets a window, or a part of a window.

Member Function Documentation

bool CEGUI::IrrlichtWindowTarget::isImageryCache ( ) const

virtual

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.
