Member Function Documentation
int QEGLContext::config() const
\since6.3 Returns the EGLConfig associated with the underlying EGLContext.
int QEGLContext::display() const
\since6.3 Returns the EGLDisplay associated with the underlying EGLContext.
[static] QOpenGLContext *QEGLContext::fromNative(int context, int display, QOpenGLContext *shareContext = nullptr)
Adopts an EGLContext context.
The same EGLDisplay passed to eglCreateContext must be passed as the display argument.
Ownership of the created QOpenGLContext shareContext is transferred to the caller.
[pure virtual] void QEGLContext::invalidateContext()
\since6.5
Marks the context as invalid
If this context is used by the Qt Quick scenegraph, this will trigger the SceneGraph to destroy this context and create a new one.
Similarly to QPlatformWindow::invalidateSurface(), this function can only be expected to have an effect on certain platforms, such as eglfs.
See also QOpenGLContext::isValid() and QPlatformWindow::invalidateSurface().
int QEGLContext::nativeContext() const
Returns the underlying EGLContext.
