To set tool tip only for the leaf nodes

[Archana Venu Aradhyula]

Hi all

I use a JTee where the elements are loaded dynamically. I want to set the tool tip only for the leaf elements. But it is setting to the entire tree.

  
 
 public Component getTreeCellRendererComponent(JTree tree,Object value, boolean sel,
boolean expanded,boolean leaf, int row, boolean hasFocus) 
{                
                Component component = super.getTreeCellRendererComponent(tree, value, sel, expanded, 
                leaf, row, hasFocus);
                this.setForeground(Color.black);
this.setBackground(new Color(107,194,206));
this.backgroundNonSelectionColor = new Color(255,255,255);
           
if (value instanceof VPDTreeViewerNode) 
                {
                    Node node = ((VPDTreeViewerNode)value).getXmlNode();
                    NodeList nodelist = node.getChildNodes();
                    for(int i = 0 ; i< nodelist.getLength() ; i++)
                    {
                    if(node.getLastChild().toString().equalsIgnoreCase("name"))
                    {
                    System.out.println("name");
                    this.setToolTipText("tooltip");
                    }
                    else
                    {
                    this.setToolTipText(null);
                    }
                    }
                   
                }   
                
                return component;                
            }
        };
 

  

How can i achieve this?

Thanks

It's hard to say without knowing more details, but two things to try are

call setToolTipText(null) even when !(value instanceof VPDTreeViewerNode)

set the tool tip on component, not on this

seems to work OK like this

    
JTree tree = new JTree();
ToolTipManager.sharedInstance().registerComponent(tree);
tree.setCellRenderer(new DefaultTreeCellRenderer(){
  public Component getTreeCellRendererComponent(JTree tree,Object value, boolean sel,
                            boolean expanded,boolean leaf, int row, boolean hasFocus){
    JLabel component = (JLabel)super.getTreeCellRendererComponent(tree, value, sel, expanded,leaf, row, hasFocus);
    component.setToolTipText(leaf? value.toString():null);
    return component;
  }
});

But still it is not working. It is considering the tooltip that i set at the last that is null.
