How to perform custom animation development？

[Grieey]

How to implement animations within a build-in widget? For example, I want to create an animation for the cursor movement in a TextInput.

Hi! I’m afraid that the text cursor cannot be animated. This would have to be implemented in Slint directly.

I think for such a use-case, it may suffice if the cursor's position (or rectangle) would be exposed and the cursor could be hidden. Then, any of the existing primitives can be used to implement a different appearance along with animation.

Excellent idea

There is already a callback cursor-position-changed in TextInput https://slint-ui.com/snapshots/master/docs/slint/src/builtins/elements.html#id19

What's missing is a way to hide the cursor. Maybe setting text-cursor-width would work.
