[news.eclipse.platform] Drop Down Menu in own View

[Werner Janjic <werner.janjic@xxxxxxxxxxxxxxxxxxxxxxxxxx>]

Hello!

I'm looking for a solution on how to implement a drop-down button in my 
own view that works like the run button on the workbench toolbar (attached).

I have the following for a menu and actions:

-- schnipp --

	/**
	 * Create menu.
	 */
	private void createMenu() {
		IMenuManager mgr = getViewSite().getActionBars().getMenuManager();
		mgr.add(aAction);
		mgr.add(bAction);
		mgr.add(cAction);
		mgr.add(dAction);
	}

	/**
	 * Create toolbar.
	 */
	private void createToolbar() {
		IToolBarManager mgr = getViewSite().getActionBars().getToolBarManager();
		mgr.add(aAction);
		mgr.add(bAction);
		mgr.add(cAction);
		mgr.add(dAction);
	}

-- schnapp --

But I'd like to create a drop down button which lets the user choose 
from different options. From the API docu I got no clue.

Thanks in advance

Werner
