This is probably a pretty newbie question, but can anyone point me towards creating some code to right click on a tree item and add a pop-up menu so I can prompt for some input and create a new child of that node?

I figured out how to change the contents of the tree in UITheme exampleBasicControls by creating a Dictionary with some child Dictionaries containing some objects, but now I seem to have a few challenges:

1. The items are not being highlighted when I click on them (they aren't in the example either).

I have the same problem, so if you find how to make it works i'm listening ^^

2. I need a nudge in the right direction to capture the right click.

Maybe you should rewrite the mouseDown: method and add a test like event yellowButtonPressed (or the button you want) ifTrue: [ "popup a menu" ]

3. If I do that and successfully add a new child to a node, I don't know how to tell the tree to refresh itself...

Send the message updateList to your MorphTreeMorph. If you have correctly build your tree it works great ( but the highlighting doesn't work :s ) Good luck Benjamin
