Multiple Windows Inside Your App - PyQt5 GUI Thursdays #36

In this video we'll add multiple windows inside our PyQT5 app with the QMDIArea Widget!

In this video we'll create a button that adds a new window into our app every time we click it.

You can use this technique to add as many windows as you want, or a limited number of specific windows.

Love your videos. The whole PyQt5 series has been really helpful tbh. Is it possible to put a tab widget in the subwindow? It's easy to do on the Designer but when I'm running the code, the tab widget is not in the subwindow. Any advice?

[RezaBesharat-ix]

I wonder if the subwindow could be an external application which is getting called? (For example NotePad)
Thanks for the well-described video.

Can we design sub forms in designer and incorporate them into MDI designed by designer???

[albertomorenogil]

While Initializing the App "UIWindow = UI()" I get "UI is not defined" why? If I have created previously class UI(QMainWindow)? Thank you.
