This method is used to add buttons to the top bar of the default ListStyles.  The EntreeActionItem is what is used to construct these buttons.

 

The following example will add a button to the bar and be rendered like the screen shot.

 

EntreeActionItem ai = new EntreeActionItem();

ai.ActionTitle = "Pages";

ai.Position = "left";

 

EntreeClickActionObject co = output.CreateClickAction();

co["screen"] = "pages";

co.SlideDirection = EntreeScreenSlideDirection.Back;

ai.SetClickAction(co);

output.AddAction(ai);
