[Jython-users] Right-click mouse on a JTree node

[<david_r_whiting@ya...>]

Hi, 

I have only spent a few hours with Jython but am
impressed with how quickly I have been able to develop
useful tools (impressed enough to have ordered Jython
Essentials).  I have no python experience and have
only dabbled a little with java, but have managed to
create a number of useful tools already.  I am now
trying to play with JTree objects and am having
trouble getting my head around working with events. 
For example, I would like to popup a menu of actions
when the user right-clicks on a node.  I have some
code (which I butchered from something I found in the
archives) which includes the following (i.e. there's
stuff before and after this, but I think this is the
relevant bit):


class myNode(swing.tree.DefaultMutableTreeNode):
    def __init__(self, ChildName):
       
swing.tree.DefaultMutableTreeNode.__init__(self,
mousePressed=self.pressed)
        self.userObject = ChildName

    def pressed(self, event):
        print "Argh! You got me!"

rootnode = myNode("Root")
child1 = myNode("Child-1")
child2 = myNode("Child-2")
child1_1 = myNode("Grandchild 1-1")


This does not print when I press the mouse on a node. 
I actually want a right-click anyway but thought I'd
have a go at that after getting some sort of response
from any kind of click.  I have not been able to find
examples searching on the, and will have to wait a
month before I'll be in the same location as the
Jython Essentials I have just ordered.  At the moment
that feels like a very long time :)

Can anyone post an example of how to popup a menu
after a right-click on a JTree node to get me going?

TIA.

Dave

I don't have one at hand - but it might help to google for JTree-examples i=
n=20
java - you'll find plenty of these, and translating them to jython is usual=
ly=20
easy going.
