Member Function Documentation

doneCurrent()

void QGLXContext::doneCurrent ( )

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 533 of file qglxintegration.cpp.

format()

QSurfaceFormat QGLXContext::format ( ) const

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 566 of file qglxintegration.cpp.

getProcAddress()

QFunctionPointer QGLXContext::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 561 of file qglxintegration.cpp.

glxConfig()

GLXFBConfig QGLXContext::glxConfig ( ) const

inline

Definition at line 40 of file qglxintegration.h.

glxContext()

GLXContext QGLXContext::glxContext ( ) const

inline

Definition at line 39 of file qglxintegration.h.

isSharing()

bool QGLXContext::isSharing ( ) const

overridevirtual

Reimplemented from QPlatformOpenGLContext.

Definition at line 571 of file qglxintegration.cpp.

isValid()

bool QGLXContext::isValid ( ) const

overridevirtual

Reimplemented from QPlatformOpenGLContext.

Definition at line 576 of file qglxintegration.cpp.

makeCurrent()

bool QGLXContext::makeCurrent ( QPlatformSurface * surface )

overridevirtual

Implements QPlatformOpenGLContext.

Definition at line 472 of file qglxintegration.cpp.

supportsThreading()

bool QGLXContext::supportsThreading ( )

static

Definition at line 715 of file qglxintegration.cpp.

swapBuffers()

void QGLXContext::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.
