How can I wait for a QWidget to close using QTestLib? [Qt5]


I am writing a QTest based test case for a class that derives from QWidget.

After showing the widget, I want the test to end as soon as the widget is closed.

My first attempt was to use QSignalSpy, only to find out that QWidget really does not send out a signal on close().

So what is the "right way" to do this using QTest primitives?


Solution

  • What if you specify Qt::WA_DeleteOnClose attribute for the widget and wait on its destroyed() signal?

    pMyTestWidget->setAttribute(Qt::WA_DeleteOnClose);
    pMyTestWidget->show();
    
    // test thread...
    QSignalSpy watchDog(pMyTestWidget, SIGNAL(destroyed(QObject*)));
    watchDog.wait();
