Member Function Documentation

◆ beginFrame()

void QCocoaGLContext::beginFrame ( )
overridevirtual

Called when the RHI begins rendering a new frame in the context.

Will always be paired with a call to \l endFrame().

Reimplemented from QPlatformOpenGLContext.

Definition at line 356 of file qcocoaglcontext.mm.

References update().

Here is the call graph for this function:

◆ doneCurrent()

void QCocoaGLContext::doneCurrent ( )
overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 536 of file qcocoaglcontext.mm.

◆ format()

QSurfaceFormat QCocoaGLContext::format ( ) const
overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 550 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 575 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.

Definition at line 42 of file qcocoaglcontext.mm.

◆ isSharing()

bool QCocoaGLContext::isSharing ( ) const
overridevirtual

Reimplemented from QPlatformOpenGLContext.

Definition at line 560 of file qcocoaglcontext.mm.

◆ isSoftwareContext()

bool QCocoaGLContext::isSoftwareContext ( ) const

Definition at line 565 of file qcocoaglcontext.mm.

Referenced by update().

Here is the caller graph for this function:

◆ isValid()

bool QCocoaGLContext::isValid ( ) const
overridevirtual

Reimplemented from QPlatformOpenGLContext.

Definition at line 555 of file qcocoaglcontext.mm.

◆ makeCurrent()

bool QCocoaGLContext::makeCurrent ( QPlatformSurface * surface)
overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 334 of file qcocoaglcontext.mm.

References update().

Here is the call graph for this function:

◆ nativeContext()

NSOpenGLContext * QCocoaGLContext::nativeContext ( ) const
override
Returns
the underlying NSOpenGLContext.

Definition at line 570 of file qcocoaglcontext.mm.

◆ swapBuffers()

void QCocoaGLContext::swapBuffers ( QPlatformSurface * surface)
overridevirtual

Reimplement in subclass to native swap buffers calls.

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

Implements QPlatformOpenGLContext.

Definition at line 503 of file qcocoaglcontext.mm.

◆ update()

void QCocoaGLContext::update ( )

Definition at line 462 of file qcocoaglcontext.mm.
