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 273 of file qwaylandglcontext.cpp.

References QtWaylandClient::QWaylandWindow::beginFrame(), and Q_ASSERT.

+ Here is the call graph for this function:

◆ createTemporaryOffscreenSurface()

EGLSurface QtWaylandClient::QWaylandGLContext::createTemporaryOffscreenSurface ( )
overrideprotectedvirtual

Reimplemented from QEGLPlatformContext.

Definition at line 242 of file qwaylandglcontext.cpp.

References QtWaylandClient::QWaylandDisplay::createSurface(), QEGLPlatformContext::eglConfig(), QEGLPlatformContext::eglDisplay(), and EGLSurface().

+ Here is the call graph for this function:

◆ 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 380 of file qwaylandglcontext.cpp.

◆ destroyTemporaryOffscreenSurface()

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

Reimplemented from QEGLPlatformContext.

Definition at line 255 of file qwaylandglcontext.cpp.

References QEGLPlatformContext::eglDisplay().

+ Here is the call graph for this function:

◆ doneCurrent()

void QtWaylandClient::QWaylandGLContext::doneCurrent ( )
overridevirtual

Reimplemented from QEGLPlatformContext.

Definition at line 335 of file qwaylandglcontext.cpp.

References QEGLPlatformContext::eglDisplay().

+ Here is the call graph for this function:

◆ eglSurfaceForPlatformSurface()

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

Implements QEGLPlatformContext.

Definition at line 393 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 280 of file qwaylandglcontext.cpp.

References QtWaylandClient::QWaylandWindow::endFrame(), and Q_ASSERT.

+ Here is the call graph for this function:

◆ 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 385 of file qwaylandglcontext.cpp.

◆ makeCurrent()

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

Reimplemented from QEGLPlatformContext.

+ Here is the call graph for this function:

◆ 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.
