EGLConfig
QEGLContext::
config
() const
Returns the EGLConfig associated with the underlying EGLContext.
該函數在 Qt 6.3 引入。

EGLDisplay
QEGLContext::
display
() const
Returns the EGLDisplay associated with the underlying EGLContext.
該函數在 Qt 6.3 引入。

QOpenGLContext
*QEGLContext::

采納 EGLContext context .
The same

passed to
eglCreateContext
must be passed as the
display
自變量。
Ownership of the created QOpenGLContext shareContext is transferred to the caller.
[pure virtual, since 6.5]
void
QEGLContext::
invalidateContext
()
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.
該函數在 Qt 6.5 引入。

EGLContext
QEGLContext::
nativeContext
() const
返迴底層 EGLContext。
