Member Function Documentation

defaultFramebufferObject()

GLuint QWasmOpenGLContext::defaultFramebufferObject ( QPlatformSurface * surface ) const

overridevirtual

Reimplement in subclass if your platform uses framebuffer objects for surfaces.

The default implementation returns 0.

Reimplemented from QPlatformOpenGLContext.

Here is the caller graph for this function:

doneCurrent()

void QWasmOpenGLContext::doneCurrent ( )

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 173 of file qwasmopenglcontext.cpp.

format()

QSurfaceFormat QWasmOpenGLContext::format ( ) const

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 126 of file qwasmopenglcontext.cpp.

getProcAddress()

QFunctionPointer QWasmOpenGLContext::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 208 of file qwasmopenglcontext.cpp.

isSharing()

bool QWasmOpenGLContext::isSharing ( ) const

overridevirtual

Reimplemented from QPlatformOpenGLContext.

Definition at line 178 of file qwasmopenglcontext.cpp.

isValid()

bool QWasmOpenGLContext::isValid ( ) const

overridevirtual

Reimplemented from QPlatformOpenGLContext.

Definition at line 186 of file qwasmopenglcontext.cpp.

makeCurrent()

bool QWasmOpenGLContext::makeCurrent ( QPlatformSurface * surface )

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 136 of file qwasmopenglcontext.cpp.

swapBuffers()

void QWasmOpenGLContext::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.
