GXT4.0 BorderLayoutContainer布局

T字型布局。

	  @Override
	  public void onModuleLoad() {

		   BorderLayoutContainer con = new BorderLayoutContainer();

		    ContentPanel cp = new ContentPanel();
		    cp.setHeading("North");
		    cp.add(new Label("North Content"));
		    BorderLayoutData d = new BorderLayoutData(.20);
		    d.setMargins(new Margins(5));
		    d.setCollapsible(true);
		    d.setSplit(true);
		    con.setNorthWidget(cp, d);

		    cp = new ContentPanel();
		    cp.setHeading("West");
		    cp.add(new Label("West Content"));
		    d = new BorderLayoutData(.20);
		    d.setMargins(new Margins(0, 5, 5, 5));
		    d.setCollapsible(true);
		    d.setSplit(true);
		    d.setCollapseMini(true);
		    con.setWestWidget(cp, d);

		    cp = new ContentPanel();
		    cp.setHeading("Center");
		    cp.add(new Label("Center Content"));
		    d = new BorderLayoutData();
		    d.setMargins(new Margins(0, 5, 5, 0));
		    con.setCenterWidget(cp, d);

		    Viewport v = new Viewport();
		    v.add(con);
		    RootPanel.get().add(v);
		    
	  }
