Question on opening a new toplevel window

[ceeeed]

Hi,
I am opening a new window, which contains a treegrid on the left and a set of tabs on the right organized in a HLayout. When a leaf tree node is selected on the left, some html text is displayed in a new tab within the TabSet. I am having two problems. I cannot close the root node in the treegrid on the left, and I cannot switch between tabs or close tabs on the right... here is a code snippet of how I open a new window and create the various components. Any help is appreciated.

thanks,



Here is the code that opens the HLayout

HLayout resultsPanel = new HLayout();
        resultsPanel.setWidth100();
        resultsPanel.setHeight100();
        resultsPanel.setShowEdges(true);
        resultsPanel.setMembersMargin(5);
        resultsPanel.setLayoutMargin(20);

Here is the tree grid:

/* Now create a TreeGrid object */
		TreeGrid treeGrid = new TreeGrid();
		/*treeGrid.setWidth(300); treeGrid.setHeight(400);*/
		TreeGridField field = new TreeGridField("Name", "Paths");  
		field.setCanSort(true); 
		//field.setCanFilter(true);
		treeGrid.setFields(field);  
		treeGrid.setData(tree);
		treeGrid.setShowAllRecords(true);
        treeGrid.setLoadDataOnDemand(false);
        treeGrid.setWidth("10%");
        treeGrid.setShowResizeBar(true);
        resultsPanel.addMember(treeGrid);

Here is the code that creates the TabSet.

/* make the main tabs where the results are displayed */
        final TabSet pathTabs = new TabSet();
        pathTabs.setTabBarPosition(Side.TOP);
        pathTabs.setTabBarAlign(Side.LEFT);
        pathTabs.setHeight100();
        resultsPanel.addMember(pathTabs);

and finally here is the code that opens a new window.

                               final Window win = new Window();
		
		/* make it modal, disable minimize and close buttons */
		win.setShowMinimizeButton(true);
		win.setShowCloseButton(true);
		win.setAutoSize(true);
		win.setAutoCenter(true);
		win.setCanDragReposition(true);
		win.setCanDragResize(true);

           win.setWidth(1200); win.setHeight(800);
        win.setTitle("Paths");
        win.addChild(resultsPanel);

        win.show();
