Can't Show Default TreeGrid Context Menu

[ccocco]

If I set up a default context menu for a TreeGrid using setContextMenu() and also set up a TreeNode context menu using addNodeContextClickHandler(), I cannot get the default context menu to display if there's a TreeNode selected, even if I right-mouse click on an area in the TreeGrid that isn't on the TreeNode itself (e.g. white space below the TreeGrid). Is there any way to get around this?

Here's a solution that will allow the proper display of a context menu based on whether the right mouse was clicked on a TreeNode or not within a TreeGrid canvas:

    public MyTreeGrid()
    {
        addRightMouseDownHandler(new RightMouseDownHandler()
        {
            public void onRightMouseDown(RightMouseDownEvent event)
            {
                if (MyTreeGrid.this.getEventRow() >= 0)
                {
                    if (event.getSource() instanceof MyTreeGrid)
                    {
                        MyTreeGrid treeGrid = (MyTreeGrid) event.getSource();
                        
                        ListGridRecord selectedRecord = treeGrid.getSelectedRecord();
                        
                        if (selectedRecord instanceof MyTreeNode)
                        {
                            displayContextMenu((MyTreeNode) selectedRecord);
                        }
                    }
                }
                else
                {
                    displayContextMenu(null);
                }
            }
        });
    }
    
    protected void displayContextMenu(MyTreeNode treeNode)
    {
        if (treeNode != null)
        {
            if (treeNode.isLeaf())
            {
                setContextMenu(MyContextMenu.getDefaultLeafMenu(this, treeNode));
            }
            else
            {
                setContextMenu(MyContextMenu.getDefaultFolderMenu(this, treeNode));
            }
        }
        else
        {
            setContextMenu(MyContextMenu.getDefaultRootMenu(this));
        }
    }
