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

Implements CEGUI::RenderTarget.
