Specify preferred method for state-sharing between controls

[Revertron]

For example, I have 2 Comboboxes.
I need to enable/disable second Combobox based on choises in the first Combobox.

Or change some text on a Button in some Comboboxs on_selected() method.

How can I do this?

You can't directly do that in the callback, with the current API. I would recommend having an external state which stores the enabled/disabled state of each combobox and an external update function which uses that external state.

We are looking into a different API for 0.4, however, which might enable this for you.
