Using Buttons for triggering Actions [message #546569]

In my application, I'd like some Actions to be triggered not only by menu items or toolbar buttons, but by normal push buttons as well. Of course, these buttons need to be automatically disabled/enabled/etc. when actions are.

This role for menus and toolbars is played by ContributionManagers, but there doesn't seem to be one for buttons.

There is an obvious approach: create an Action subclass which takes a Button as a constructor parameter and overriding setEnabled/setDisabled/setText/... but is it actually needed or is there a simpler way?

You'd have to write your own subclass of ContributionManager. Something
like org.eclipse.jface.action.StatusLineManager manages
IContributionItems on a Composite, which is similar to what you want.
