I have a custom tree item renderer that is working out great except one
little small problem. In my item renderer I have some actions for adding /
removing / renaming directories. The only time I don't want the remove or
rename context menu items is when its the home directory. I know that I can
hack it and hard code it here because the data object is passed to each
function.
What I am trying to do though is going back to the main part of the
applicaiton (or pass in) the baseDirectory so I can account for change. Has
anyone got data in/or out of a renderer before? If it was just another class
it would be easy to put in the constructor but there is no constructor when
you add it to the tree.
