doneCurrent()

void QCocoaGLContext::doneCurrent ( )

overridevirtual

Implements QPlatformOpenGLContext.

Here is the call graph for this function:

format()

QSurfaceFormat QCocoaGLContext::format ( ) const

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 481 of file qcocoaglcontext.mm.

getProcAddress()

QFunctionPointer QCocoaGLContext::getProcAddress ( const char * procName )

overridevirtual

Reimplement in subclass to allow dynamic querying of OpenGL symbols.

As opposed to e.g. the wglGetProcAddress function on Windows, Qt expects this methods to be able to return valid function pointers even for standard OpenGL symbols.

Implements QPlatformOpenGLContext.

Definition at line 501 of file qcocoaglcontext.mm.

initialize()

void QCocoaGLContext::initialize ( )

overridevirtual

Called after a new instance is constructed.

The default implementation does nothing.

Subclasses can use this function to perform additional initialization that relies on virtual functions.

Reimplemented from QPlatformOpenGLContext.

Here is the call graph for this function:

isSharing()

bool QCocoaGLContext::isSharing ( ) const

overridevirtual

Reimplemented from QPlatformOpenGLContext.

isValid()

bool QCocoaGLContext::isValid ( ) const

overridevirtual

Reimplemented from QPlatformOpenGLContext.

Here is the caller graph for this function:

swapBuffers()

void QCocoaGLContext::swapBuffers ( QPlatformSurface * surface )

Reimplement in subclass to native swap buffers calls.

The implementation must support being called in a thread different than the gui-thread.
