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 387 of file qwaylandglcontext.cpp.

◆ createTemporaryOffscreenSurface()

EGLSurface QtWaylandClient::QWaylandGLContext::createTemporaryOffscreenSurface ( )
overrideprotectedvirtual

Reimplemented from QEGLPlatformContext.

Definition at line 282 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 513 of file qwaylandglcontext.cpp.

◆ destroyTemporaryOffscreenSurface()

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

Reimplemented from QEGLPlatformContext.

Definition at line 295 of file qwaylandglcontext.cpp.

◆ doneCurrent()

void QtWaylandClient::QWaylandGLContext::doneCurrent ( )
overridevirtual

Reimplemented from QEGLPlatformContext.

Definition at line 465 of file qwaylandglcontext.cpp.

◆ eglSurfaceForPlatformSurface()

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

Implements QEGLPlatformContext.

Definition at line 521 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 396 of file qwaylandglcontext.cpp.

◆ initialize()

void QtWaylandClient::QWaylandGLContext::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 QEGLPlatformContext.

Definition at line 338 of file qwaylandglcontext.cpp.

◆ makeCurrent()

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

Reimplemented from QEGLPlatformContext.

Definition at line 412 of file qwaylandglcontext.cpp.

◆ runGLChecks()

void QtWaylandClient::QWaylandGLContext::runGLChecks ( )
overrideprotectedvirtual

Reimplemented from QEGLPlatformContext.

Definition at line 304 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.
