eclipse - how to show up the perspective button without click? -

I have two approaches, but to see the other perspective, as you know that on the 'Open Perspective' button Is there a way to click that the second perspective button is automatically visible when the app starts?

It looks like you have the default size of the perspective switcher (times with perspective button) ) To do this, maybe you can use an example of ActionBarAdvisor class; You probably also need a workbenchwindow adware class.

I do not see any way to directly reach the switcher object, so I think you have to look at the component tree to find it.

It seems that there should be an easy way, but I do not see one.
