Member Function Documentation

HDC glfPBuffer_WGL::CreateDeviceContext	(	int	width,
		int	height,
		int	pixelFormat
	)

protectedvirtual

Implements BIAS::glfRenderingContext_WGL.

Definition at line 42 of file glfPBuffer_WGL.cpp.

void glfRenderingContext_WGL::Destroy ( )

virtualinherited

Uninitializes the rendering context.

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

Implements BIAS::glfRenderingContext.

Definition at line 146 of file glfRenderingContext_WGL.cpp.

void glfPBuffer_WGL::DestroyDeviceContext ( )

protectedvirtual

Implements BIAS::glfRenderingContext_WGL.

Definition at line 69 of file glfPBuffer_WGL.cpp.

void glfRenderingContext_WGL::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 165 of file glfRenderingContext_WGL.cpp.

void glfRenderingContext_WGL::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
