EGLConfig
QEGLContext::
config

Returns the EGLConfig associated with the underlying EGLContext.
This function was introduced in Qt 6.3.

shareContext
= nullptr)
Adopts an EGLContext context .
The same
EGLDisplay
passed to
eglCreateContext
must be passed as the
display
自变量。
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.
类似于 QPlatformWindow::invalidateSurface (), this function can only be expected to have an effect on certain platforms, such as eglfs.
This function was introduced in Qt 6.5.
