I've added a command that toggles a two state view preference in my app. I created a HandledMenuItem for this command and set the type to Check. I also added this to a menu and added a Handler for the command and a keybinding.

The menuitem shows up in the menu with a checkbox and the state of the check is remembered correctly. Also, my handler is called when I activate the menuitem or via the keybinding. So far so good.

Here's the problem: I need to know what the state of the check is both in my handler and in my view code that consumes this preference. But I can't figure out how to access the check state either in the handler or elsewhere.

What's the correct way to get at this info?

I found an answer and it's easy of course. Just inject handler with (MMenuItem item) and call item.isSelected().

Unfortunately, the answer I found is incomplete.

While it works when the handler is activated by the menuitem, it fails when it's activated by a keybinding. In the case of a keybinding activation, the MMenuItem will be not be resolved. How is the handler supposed to get at the state which the menuitem holds in this situation?

I suppose the situation gets even worse if there are multiple menuitems bound to the same handler, and with different types.

If it is a preference why don't you set one? You can get preferences
injected using @Preference("myprefvalue") in the @Execute and in views
using @Inject @Preference("myprefvalue")

I got that one working to synchronize from the HandledMenuItem to the Code! But how could I initialize the state of the HandledMenuItem at start given the Preference?

Or more generally, how can I set the state of a HandledMenuItem given by the state of the code at all?

Thanks!
