Member Function Documentation

beginFrame()

void QtWaylandClient::QWaylandGLContext::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 302 of file qwaylandglcontext.cpp.

createTemporaryOffscreenSurface()

EGLSurface QtWaylandClient::QWaylandGLContext::createTemporaryOffscreenSurface ( )

overrideprotectedvirtual

Reimplemented from QEGLPlatformContext.

Definition at line 246 of file qwaylandglcontext.cpp.

defaultFramebufferObject()

GLuint QtWaylandClient::QWaylandGLContext::defaultFramebufferObject ( QPlatformSurface * surface ) const

overridevirtual

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

The default implementation returns 0.

Reimplemented from QPlatformOpenGLContext.

Definition at line 410 of file qwaylandglcontext.cpp.

destroyTemporaryOffscreenSurface()

void QtWaylandClient::QWaylandGLContext::destroyTemporaryOffscreenSurface ( EGLSurface surface )

overrideprotectedvirtual

Reimplemented from QEGLPlatformContext.

Definition at line 259 of file qwaylandglcontext.cpp.

doneCurrent()

void QtWaylandClient::QWaylandGLContext::doneCurrent ( )

overridevirtual

Reimplemented from QEGLPlatformContext.

Definition at line 367 of file qwaylandglcontext.cpp.

eglSurfaceForPlatformSurface()

EGLSurface QtWaylandClient::QWaylandGLContext::eglSurfaceForPlatformSurface ( QPlatformSurface * surface )

overrideprotectedvirtual

Implements QEGLPlatformContext.

Definition at line 423 of file qwaylandglcontext.cpp.

endFrame()

void QtWaylandClient::QWaylandGLContext::endFrame ( )

overridevirtual

Called when the RHI ends rendering a in the context.

Is always preceded by a call to \l beginFrame().

Reimplemented from QPlatformOpenGLContext.

Definition at line 309 of file qwaylandglcontext.cpp.

getProcAddress()

QFunctionPointer QtWaylandClient::QWaylandGLContext::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.

Reimplemented from QEGLPlatformContext.

Definition at line 415 of file qwaylandglcontext.cpp.

makeCurrent()

bool QtWaylandClient::QWaylandGLContext::makeCurrent ( QPlatformSurface * surface )

overridevirtual

Reimplemented from QEGLPlatformContext.

Definition at line 321 of file qwaylandglcontext.cpp.

runGLChecks()

void QtWaylandClient::QWaylandGLContext::runGLChecks ( )

overrideprotectedvirtual

Reimplemented from QEGLPlatformContext.

Definition at line 268 of file qwaylandglcontext.cpp.

swapBuffers()

void QtWaylandClient::QWaylandGLContext::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.

Reimplemented from QEGLPlatformContext.

Definition at line 372 of file qwaylandglcontext.cpp.
