From 17a59f661398bf56aeaba4187f55d07eea09c578 Mon Sep 17 00:00:00 2001 From: Thomas Senyk Date: Wed, 14 Dec 2022 08:20:36 +0100 Subject: Add QEGLContext::invalidateContext QEGLContext::invalidateContext will mark that egl context is invalide and trigger SceneGraph to destroy it, create a new one and re-create and re-upload all resources (e.g. textures) associated with the current state of the SceneGraph In addition this change also improves QEglFSWindow::invalidateSurface() and QEglFSContext::eglSurfaceForPlatformSurface(..) Where QEglFSWindow::invalidateSurface() will now destroy the corresponding EGLSurface via eglDestroySurface, including "unbinding" it from the current thread via eglMakeCurrent and un-setting the screen's EGLSurface in case it's the same resource. QEglFSContext::eglSurfaceForPlatformSurface(..) will now call QEglFSWindow::resetSurface() in case of getting a EGL_NO_SURFACE from the QEglFSWindow (which happens if above invalidateSurface() was called before) - therefor re-creating the resource if it was destoyed via QEglFSWindow::invalidateSurface() Pick-to: 6.5 Change-Id: I37badd1fc11e993c395fb1502e9bd27ebe18b821 Reviewed-by: Laszlo Agocs --- src/gui/platform/unix/qunixnativeinterface.cpp | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'src/gui/platform/unix/qunixnativeinterface.cpp') diff --git a/src/gui/platform/unix/qunixnativeinterface.cpp b/src/gui/platform/unix/qunixnativeinterface.cpp index 1cca97b34c8..1f891de0f50 100644 --- a/src/gui/platform/unix/qunixnativeinterface.cpp +++ b/src/gui/platform/unix/qunixnativeinterface.cpp @@ -123,6 +123,22 @@ QOpenGLContext *QNativeInterface::QGLXContext::fromNative(GLXContext visualBased \return the EGLDisplay associated with the underlying EGLContext. */ + +/*! + \fn void QNativeInterface::QEGLContext::invalidateContext() + \since 6.5 + \brief 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. + + \sa QOpenGLContext::isValid(), QPlatformWindow::invalidateSurface() +*/ + QT_DEFINE_NATIVE_INTERFACE(QEGLContext); QT_DEFINE_PRIVATE_NATIVE_INTERFACE(QEGLIntegration); -- cgit v1.2.3
