Detailed Description

Provides window system independent access to GL contexts.

All OpenGL operation occurs within a current GL Context. The GL contexts used by an application are allocated and managed by the window system interface layer, i.e. Qt, GLUT, GLX, etc.

This class provides a way for lower-level OpenGL framework code to get useful information about the GL contexts in use by the application.

This mechanism depends on the application code registering callbacks to provide access to its GL contexts.

Member Function Documentation

virtual bool _IsEqual ( const GlfGLContextSharedPtr & rhs ) const

protectedpure virtual

Returns true if this context is equal to rhs.

Implemented in GlfTestGLContext.

virtual bool _IsSharing ( const GlfGLContextSharedPtr & rhs ) const

protectedpure virtual

Returns true if this context is sharing with rhs.

Implemented in GlfTestGLContext.

virtual void _MakeCurrent ( )

protectedpure virtual

Makes this context current.

Implemented in GlfTestGLContext.

static GLF_API bool AreSharing	(	GlfGLContextSharedPtr const &	context1,
		GlfGLContextSharedPtr const &	context2
	)

static

Returns true if context1 and context2 are sharing.

virtual GlfGLContextSharedPtr CreateSharingContext ( )

inlinevirtual

Creates a new GlfContext that shares GL resources with this context.

The purpose of this function is to be able to create a new GL context on a second thread that shares with the context on the main-thread. If the GlfContext implementation does not support sharing contexts null is returned. Example usage: Main-thread: RegisterGLContextCallbacks(); GlfGLContext::MakeCurrent(...); Second-thread: s = GetCurrentGLContext(); c = s->CreateSharingContext();

static GLF_API void DoneCurrent ( )

static

Makes no context current.

static GLF_API GlfGLContextSharedPtr GetCurrentGLContext ( )

static

Returns an instance for the current GL context.

static GLF_API GlfGLContextSharedPtr GetSharedGLContext ( )

static

Returns an instance for the shared GL context.

GLF_API bool IsCurrent ( ) const

Returns true if this context is current.

static GLF_API bool IsInitialized ( )

static

Returns whether this interface has been initialized.

GLF_API bool IsSharing ( GlfGLContextSharedPtr const & otherContext )

Returns true if this context is sharing with otherContext.

virtual bool IsValid ( ) const

pure virtual

Returns true if this context is valid.

Implemented in GlfTestGLContext.

static GLF_API void MakeCurrent ( const GlfGLContextSharedPtr & context )

static

Makes context current if valid, otherwise makes no context current.
