Dialog popup on wrong screen when parent is ActiveX embedded

XMLWordPrintable

      I found an issue with dialog pop-ups from ActiveX embedded apps.

      When an application is embedded in another application using ActiveX (setControl on a AxWidget) it seems to have problems to show dialogs on the correct screen.

      If the application is started on screen != 0 the dialogs keep poping up on screen 0.

      I have attached a fairly simple example to demonstrate the issue. As I am using Visual Studio I am not sure if this QT based pro example compiles from start. I based the project files on the QT examples.

      The ActiveXWidget should be compiled and than the app should be registered (/regserver).

      The ActiveXApplication should be started and select the option embed application. From the new embedded application select the option to start a dialog.

      Small remark: programatically the ActiveXApplication start on screen 1 instead of 0! See mainWindow.setGeometry.
