Description

Currently I have to use add(Action|Mouse)Listener if I want to register a action/mouse listener to a component. It would be great if Groovy support 'addAction' and 'addActions' methods that will cleverly register any kind of EventListener to a component without a need to call methods related to it (pre configured via Groovy DSL).

So this is what I basically do in my swing projects:

// Add addAction syntax to java.awt.Component
Component.metaClass."addAction" = { action ->
   if (action instanceof MouseListener)
	addMouseListener(action);
   else
	addActionListener(action);
}
		
// Add addActions syntax to java.awt.Component
Component.metaClass."addActions" = { actions ->
   for (def action: actions)
	addAction(action);
}
