If I run application with call
QtWebEngine::initialize();
It generate this message in console:
QtWebEngine::initialize() called with QCoreApplication object already created and should be call before. This is depreciated and may fail in the future. Attribute Qt::AA_ShareOpenGLContexts must be set before QCoreApplication is created.
I can reproduce it on WebView Example from Qt, so it can be used as minimal code for reproducing.
Looks like WebView plugin instance init call QtWebEngine::initialize() method, but it has check in his body:
void initialize()
{
QCoreApplication *app = QCoreApplication::instance();
if (app) {
qWarning("QtWebEngine::initialize() called with QCoreApplication object already created and should be call before. "\
"This is depreciated and may fail in the future.");
QtWebEngineCore::initialize();
return;
}
// call initialize the same way as widgets do
qAddPreRoutine(QtWebEngineCore::initialize);
}
So we have inconsistency: QtWebView::initialize() must be called after application instance creation, but QtWebEngine::initialize() must be called before.
