void glfRenderingContext_GLX::Destroy ( )

Uninitializes the rendering context.

This method must be called before the application quits and after all Open GL resources (textures etc.) have been deleted.

void glfRenderingContext_GLX::DoneCurrent ( )

virtualinherited

Removes the current state of this context.

Must be called before MakeCurrent is called from another thread.

Reimplemented from BIAS::glfRenderingContext.

Definition at line 168 of file glfRenderingContext_GLX.cpp.

void glfRenderingContext_GLX::GetConfig ( glfRenderingContextConfig & config )

virtualinherited

Gets the currently used config of the rendering context.

The rendering context must have been successfully initialized before this method may be called.

Parameters

config The config structure to be filled
