[news.eclipse.platform.rcp] Launch Command at startup

[roel.denijs@xxxxxx (Roel De Nijs)]

Hi all,

I have a toolbar with a command (style = toggle). snippet from plugin.xml

<menuContribution locationURI="toolbar:org.eclipse.ui.main.toolbar">
	<toolbar id="be.aclvb.demo.ui.toolbars.main">
		<command
		   commandId="org.eclipse.ui.file.toggle.navigation"
		   icon="icons/tree.gif"
		   label="SHOW NAVIGATION"
		   style="toggle">
		</command>
	</toolbar>
</menuContribution>

when user hits the button first time, a view has to be shown. when he hits 
it a second time, same view has to hide. 
So i created a handler that shows and hides the view, and also updates the 
label of the button in the toolbar with implementing the IElementUpdater. 
and when i click on the button (several times) everything works fine.

But at startup the view has to be shown, so i want to invoke the command 
at startup of my rcp application. how can i achieve this?

Thanks already!
Regards,
Roel
