[Jython-users] JTree and custom objects problem

[Kevin M. <qk...@lm...>]

Thanks for all the help so far.

I am trying to use a tree in a splitpane. I am using the Java Swing
tutorial on trees as a reference
http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html

According to this, if I add a custom object to the tree I must implement
it's toString method. But it doesn't seem to work:


from pawt import swing

Node = swing.tree.DefaultMutableTreeNode

class CustomObject:
	def __init__(self, key, value):
		self.key = key
		self.value = value

	def toString(self):
		print "toString: ", self.key
		return self.key

top=Node("Test")
top.add(Node(CustomObject("key","value")))
tree=swing.JTree(top)

frame=swing.JFrame()
frame.getContentPane().add(tree)
frame.visible=1
