Getting widget from other app?



  • Hi,
    I have my app i.e. App1, where I have some QWidgets (as containers). In other app i.e App2 there are some other widgets like QLabel, QCheckBox and so on. That other app should have a possibility to show its widgets in my app.
    Any idea how can I do it?
    I tried to get WId of picked widget (by using winId() method) and create windowContainer for that widget, but there is many problems related to it.

    I can't do this by using QWidget::find(WId id) because this is in-process, and that two apps (App1 and App2) are two separetly processes.

    I don't know if I wrote it clearly, so if something is to explain I will try to do this.



  • Hi,
    why do you need to do that ?
    Thanks



  • I need it to display widgets from other apps in my app.
    The problem is that I never know what kind of widgets it would be. Only what I can get from that external app (not the same process as mine) is WId of widget that should be displayed.



  • Can you get by with just an image of what is displayed. That's easy enough to send to another app. Otherwise I would suggest you write your own serializer and deserializer of the widget you want to recreate. It would not be trivial to write such methods for widgets, I believe it would be much easier to do with QML.
