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


Code:
HLayout resultsPanel = new HLayout();
resultsPanel.setWidth100();
resultsPanel.setHeight100();
resultsPanel.setShowEdges(true);
resultsPanel.setMembersMargin(5);
resultsPanel.setLayoutMargin(20);
Here is the tree grid:

Code:
/* 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.


Code:
/* 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.



Code:
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();
