Beta 1 - NorthSouthContainer behavior different from TopBottomComponent of DP5?

[Konstantin.Scheglov]

Adding container.forceLayout() does not help.

Sorry, you are correct. You are missing the center region completly, which is required to position it at the south. The layout method is not doing anything without a center widget defined.

public class ImageViewer implements EntryPoint {    public void onModuleLoad() {
      RootPanel rootPanel = RootPanel.get();
      {
        NorthSouthContainer container = new NorthSouthContainer();
        container.setBorders(true);
        rootPanel.add(container, 10, 10);
        container.setWidget(new HTML());
        container.setSize("250px", "200px");
        // "south" rendered on "north", not stretched horizontally
        container.setSouthWidget(new Button("SSSSSSSSSSSS"));
      }
    }
  }

1. Why I do this? Because I can. GXT 3 is about making things easier and safer, right? :-)

2. I've tried to add container after setting south widget. No difference.

You should not write your code in a way that forces two layoutchains, as this will always end in being slow. Before adding something to the rootpanel, first build it completly. The good thing is that GXT alraedy caches multiple layout chains.

However a NorthSouthContainer always requires the center region, please see the edited post.

I updated the code to update atleast the width if no center region is specified, this change is in SVN now. However the south part will always be displayed under the center region. If there is no, than its under the north region. If that is also missing than its the top part.

OK, thank you for help and fixes.

The change will be in the next beta release.
