Access handler reference [message #336063]

Hi,
Would anyone know how to access the instance of a handler, given the
command ID? I know the handler is instantiated by the workbench, and I
need call a method on it - i'd rather not instantiate it again.

Cheers!

You can't get to a handler, at least not from the framework.

You could have your handler post itself to your plugin Activator, so you
can retrieve it from there once it is created.

ex: class MyHandler {....
public MyHandler() {
Activator.getDefault().setHandler(this);
}....}

Then you can use it Activator.getDefault().getHandler()!=null etc
