Hi,
I have this Job that needs to be executed. The Job reads content from a
smartcard and then does a webservice call, so it can take a while until
it is finished.
The user should be able to execute this from the menu, a shortcut and a
button on some view.
By defining an actionSet i've got a menu-item linked to an
IWorkbenchActionDelegate, so I guess i can schedule the Job in the run
method there.
I've added a org.eclipse.ui.commands extension and via the definitionId
in Action i now have a shortcute that executes the action.
The problem is when I want to use the button.
I've added a SelectionListener to the button and in the
widgetSelected(..) method I've created a new actionDelegate Object and
passed 'new Action(){}' to its run method.
The execution of this action works as long as I don't access
IWorkbenchWindow reference in my actionDelegate implementation. this
ofcourse is a null reference here because the init-method wasn't called.
Is there a way I can access the object that's already initiated so I can
easily provide the window as a parent shell for a message dialog? Or
should I get a reference to the current IWorkbenchWindow in some other way?
Thanks,
kristof.

1. you can use org.eclipse.ui.actionSets to add it to the main toolbar,
or org.eclipse.ui.viewActions to add it to the view toolbar.
2. If you've bound your action to a command using the definitionId, you
can call that command from the handler service ... no need to
instantiate another action:
IHandlerService service = (IHandlerService)
getSite().getService(IHandlerService.class);
service.executeCommand(definitionId, null);
You could put that in your widgetSelected(*) method.
3. you could give up on your action, and write it in a handler instead.
Then your keybinding and command work the same way. The only
difference is you would put that service.executeCommand(*) code in your
IActionDelevate#run(*) method.
