close dialog together with application

Message 1 in thread

Hello!

I have an application that opens a modeless dialog at start up (a 
logging window). After exiting the application the dialog window is 
still open but I want it closed together with the application.
The parent is set to the QMainWindow.
Any suggestions welcome.

Thanks,
Michael

Hi Michael,

I suggest calling QApplication.quit(). That shuts down the event loop 
and closes all windows. It also means that you can add custom 
application shutdown logic after QApplication.exec();

best regards,
Gunnar

public class Dialog {

     public static void main(String args[]) {
         QApplication.initialize(args);

         QMainWindow window = new QMainWindow() {
             protected void closeEvent(QCloseEvent e) {
                 QApplication.quit();
             }
         };

         QWidget dialog = new QWidget(window);

         window.show();
         dialog.show();

         QApplication.exec();

         // Custom application shutdown code...
     }

}
