I want to get a subwindow where I can see more information while the main scene continues to be displayed. This subwindow must be able to be moved outside the main scene.
I tried using Viewports and Cameras but since only one camera can be activated, it doesn't show all information (main scene and other window).

Is it possible to get window class as the same way to get it Godot 4? If not possible, is there a way to get something similar?

    Aarongp I tried using Viewports and Cameras but since only one camera can be activated, it doesn't show all information (main scene and other window).

    You can have multiple cameras.

    Put the information you want to show in the separate scene that the subviewport camera sees.

      kuligs2 but the view of Camera3D_Top do not exist as a subwindow.
      The information is superimposed in the main scene. I want to get a subwindow that can be dragged off the main scene.

        kuligs2 The link is about Godot 4 and I am using Godot 3. I already mentioned this at the beginning

        The usage is that when you click a button, a new window is created separate from the window where the main scene is and in this new window you could see other scene different.

        I need something like window class in Godot 4 to create other different windows.

          Aarongp sorry, didnt see that its about gd3.. good luck

          No luck. Godot 3 is single window only. Per process. The only way to get a second window would be to run a second instance of Godot and then send the data from the main instance to the secondary one somehow. Sounds pretty involved. Probably not worth the trouble.

            Zini if that so, then you could write up multiplayer thingie, like that second window instance is like a new peer that connects to the main window via multiplayer api
