问题 I have a big rectangle with a button centered. I would like that my rectangle is transparent to mouse events except for the button, which must be clickable. I mean, I would like to be able to select code under my rectangle with the mouse, exactly as if no Rectangle was displayed. I have added a MouseArea for all the big Rect, trying to ignore mouse events, but it does not work. I read that 'Qt::WA_TransparentForMouseEvents' is used for that purpose, but in Qt windows as fasr as I know, not

问题 I'd like to use an ApplicationWindow as a main file and be able to switch to other QML files from C++ with QQuickView::setSource(const QUrl & url) . Basically it would do this: start-up => loads main.qml ( ApplicationWindow ) => click on help button => C++ loads help.qml file => etc. int main(int argc, char *argv[]) { QApplication app{argc, argv}; CustomQQuickView view; view.setSource(QUrl{"qrc:/main.qml"}); view->show(); return app.exec(); } main.qml ApplicationWindow { visible: true width:

Both of the .qml requires me to include some Cpp models inside hence, I'm using QQmlApplicationEngine to register the Cpp models. I found out that using QWidget::createWindowContainer() I'm able to display multiple Window s for a single project. This works perfectly fine for the first QML file. The code snippets looks like this: QQmlApplicationEngine* engine = new

Memory management issue with deleting QQuickView in Qt5.3(mingw32)

问题 We are developing an application with Qt/Qml (Qml is embedded in the QWidget). When deleting a QWidget that contains a QQuickView (embedded), the allocated memory won't be freed entirely. By adding a QWidget to application, about 30MB of memory will be allocated but when the widget deletes, only about 20MB of memory will be freed. In the destructor of QWidget, I have deleted the QQuickView instance and there are no other big objects. Also, I am pretty sure that the QQuickView doesn't release

In the destructor of QWidget, I have deleted the QQuickView instance and there are no other big objects. Also, I am pretty sure that the QQuickView doesn't release memory properly. How can I free entire memory allocated by QQuickView? NOTE: The code is really big
