Text Edit: Add a property to handle scrolling automatically

[hunger]

This was added to #474:

hello, I advice that it is necessary to add an attribute to determine whether the scroll bar automatically scrolls the latest content when the content exceeds the current display area.

I extracted that so it does become more visible.

Is that really something we want as a property?
Maybe something like scroll-to-end() or some function like that.
It is currently even possible by using the foo.set-selection-offsets(foo.text.length, foo.text.length) (only that .length is not implemented in Slint, but you can get it with a native callback)

I wanted to capture the issue and it was going to get lost as a comment to some old issue:-)

I am not sure it warrants a property, maybe we should just add it as a recipe instead.

I'm working on creating a log viewer and am facing some difficulties. Every new line is added at the bottom of the scrollview, but I can't seem to find a way to control the scrolling or focus on the last item. Any suggestions would be greatly appreciated.

The behaviour I suggest we implement is that if the cursor as at the end of the TextEdit and text is appended, the cursor should remain visible - which implies scrolling. I think fixing this does not require adding new API - for the very common case. (IF the TextEdit is read-only then there's still a cursor, so the logic can remain the same).

@felipefdl - did you make any progress on this? I'm looking to do essentially the same thing: display text in a scrolling view, as it is added.

No, I migrated my app to tauri for that :/
