This is for Ade to answer the question on Sep 11, 2006
No-one has answered your question. I don't know if it is because they
thought you should be able to figure out yourself. After investigating
your problem, I at least think so because it took me under a hour from
the problem to the solution and I've never used the treecontrol nor
looked at its demos nor the souce code nor the documentation. Here's
what I did and what I think you should have done also:
1. I looked at the Pythoncard treecontrol demo and its source code. The
events handled by PythonCard are listed at the beginning of the
minimaltree code
2. I looked at the wxPython demo finding the treecontrol demo, running
it and browsing its source code. I found out that the event generated by
clicking the item text is OnSelChanged.
3. But your original headache was how to find the path to the root. Well
I had the third and last help item left: wxWidgets documentation. There
I browsed the wxTreeCtrl documentation looking for something with Parent
in it. Found GetParent with a note to use GetItemParent instead.
4. Copied the minimaltree example to my own directory and started
modifying and debuggin it to get what I/you wanted. Copied the
on_tree_itemExpanding method and modified it to become (after 3-4
iterations):
def on_tree_selectionChanged(self, event):
tree = self.components.tree
item=event.item
#obj = int(tree.getItemText(item))
#print 'selChanged', obj
if item != self.root:
listToRoot = []
while item:
listToRoot.append(tree.getItemText(item))
item = tree.GetItemParent(item)
#print item
listToRoot.reverse()
print '_'.join(listToRoot)
event.skip()
I think this is near enough the thing you wanted, isn't it?
