BorderLayout Collapsible doesn't work?

[phoboshero]

I got a base class (MasterDetailDisplay.java) extends GPanel with following code:

masterLayoutData = new BorderLayoutData(Style.LayoutRegion.WEST);
masterLayoutData.setMargins(new Margins(0, 5, 0, 0));
master = new LayoutContainer(new FitLayout());
setLayout(new BorderLayout());
add(master, masterLayoutData);
...(add stuff in centre area)

somewhere in my display class:
masterDetailDisplay = new MasterDetailDisplay();
masterDetailDisplay.setCollapsible(true); ----- which will then call masterLayoutData.setCollapsible(true);

then I add a Grid into my master layout container. when its showing up on the screen, it doesn't appear a button or something I can collapse my master layout container.

what problem I got in my code?

Thanks,
Yu

you missed masterLayoutData.setCollapsible(true);

Hope this will work

That's because MasterDetailDisplay is a base class I would like to use in many places so didn't set collapsible to true at the very beginning. However, when I create a new instance of that, I set the collapsible to true at bottom. But it seems like its not working:(

You add your grid directly to your container with a borderlayout? That wont work with collapsible. You need to put the Grid into a ContentPanel and this contentpanel has to be put into the container with the borderlayout.

Yeah, after I change my master layout container to a content panel, its working now:)

Thank you!
