Expand ContentPanel in AccordionLayoutContainer

Question

In my project I using gwt 2.5.1 + gxt 3.0.1 + gwtp (plugin for eclipse), and MVP - pattern. I use AccordionLayoutContainer with 3 ContentPanel. When the application loads all panels collapsed. How to make that one panel was expanded, depending on which parameter is specified in the link?

Answer 1

With:

navigator = new AccordionLayoutContainer();
navigator.setExpandMode(ExpandMode.SINGLE_FILL);

tells GXT to have only one panel open at one time.

And with navigator.setActivePanel(widget); you can set the active widget.
