Thread: JTree Selection Order Icons

Hi,

When a user selects a leaf, I want to display an icon(number picture) displaying the order in which this leaf is selected. i.e, if node has three leaves, if I click on the first, second and third, I want to display 1,2,3 with the node text. It the user deselects second node, I should automatically renumber the other selected nodes 1 and 2.

I can use the TreeCellRenderer and set the icone for the selected leaf, but, at the same time how do I refresh the icons on the other leafs ?

public Component getTreeCellRendererComponent(	JTree tr, 
Object value, 
boolean sel, 
boolean expanded, 
boolean leaf, 
int row, 
boolean focus) 
{
super.getTreeCellRendererComponent(tree, value, sel, expanded, leaf, row, focus); 
/*if (sel) {
this.setFont(getFont().deriveFont(Font.BOLD + Font.ITALIC));	
}
else { 
this.setFont(getFont().deriveFont(Font.PLAIN));
} 
*/
if ((value != null) && (value instanceof DefaultMutableTreeNode)) 
{ 
String sSpecial = ((NBTreeNode) value).sSpecial;
boolean bSelected = ((NBTreeNode) value).bSelected;
if(sSpecial != null)
{ 
if (Integer.parseInt(sSpecial) >= 0 && bSelected == true)
this.setIcon(Icons[Integer.parseInt(sSpecial)]);
else
this.setIcon(null);
} 
 
}
 
 
 
return this; 
}

Any help is greatly appreciated.

Thank you
