Wrap ListView and GridView in ScrolledWindow

[Rirusha]

The demo did not work correctly: when creating more than 200 widgets and scrolling down, widgets are not dynamically created. Each Gtk.ListView or Gtk.GridView should be placed in Gtk.ScrolledWindow without intermediaries (Scrolling from Adw.StatusPage will not work)

Thanks!

This needs a bit more work / attention to detail :)

I see 2 issues

The whole content shifting upwards when adding first new items:

Screencast.from.2024-03-13.23-41-30.mp4

The content width changing

Screencast.from.2024-03-13.23-44-42.mp4

If you revert unrelated changes - that probably fixes them
Please also double check that all properties on ScrolledWindow are necessary

Done. 🫡

I also wanted to ask, how welcome is changing the code of an existing demo? That is, I could add text output with "widget loaded/unloaded at position n" and add 500 instead 3 default widgets. One of the features of ListView/GridView is the display of a huge amount of content without hitting performance.

if it's an improvement go for it

That's an improvement 👍
