[Pythoncard-users] TreeControl

[Ade <sk...@bl...>]

Thanks for the info, Jussi. From your text i went through the wx
documentation for TreeControl (i hadn't even thought of thw wx stuff)

I found that the thing I was looking in my blinkered way after some
trial and error was the tree.SetPyDataItem and tree.GetPyDataItem.

This means that each node in the tree can be associated with an element
in, say, a list which is the real data I want to get returned.

I like your way by kind of recursing back to the root getting all the
text of all the branches between the node selected and the root.

Thank you very much :)

  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):

  code <snip>

  I think this is near enough the thing you wanted, isn't it?
