RE: getSelectedNode from within configureContextMenu could return null

[Roger L. Whitcomb]

Hi Josh,
        Yes, this is by design.  The right-click doesn't "select" a node, so 
the right way to figure out what node was clicked on is to use the 
"getNodeAt(y)".

        Thanks for the code example and for using Pivot!

Subject: getSelectedNode from within configureContextMenu could return null

Hi,

I've added a context-menu to my TreeView. Now, if I just
hover(position) the mouse over a tree-node and right click on that node(without 
selecting that node with a left-click) then
TreeView.getSelectedNode() returns null. But I can certainly get the node by 
using Tree.get(). So just wanted to check if this is as designed. Anyways, just 
wanted to share my test-case so that other beginners like myself can save some 
time.


here's my existing code(Note: In this particular code-path I'm going to stop 
using getSelectedNode and just use Tree.get):

my_tree.setMenuHandler(new MenuHandler.Adapter() {

public boolean configureContextMenu( Component component, Menu menu, int x, int 
y ) {

Path nodePath = my_tree.getNodeAt(y);

Object obj = my_tree.getSelectedNode();

if (obj == null) {
   obj = Tree.get(my_tree.getTreeData(), nodePath);
   if (obj == null)
     return true;
}

// use obj ...
return false;
}

thanks
