Hi folks.
I'm working with a multiple-selection wxTreeCtrl and I want to
programmatically change the label for individual items from time to time. I
call wxTreeCtrl::SetItemText(treeItemId, String) passing in the treeItemId
of the one tree item currently selected. I get an AssertionError saying
this method is only available with single selection wxTreeCtrl's. So how
can I change the label text programmatically in a multi-select wxTreeCtrl?
Thanks.

Platform, version and sample code?
If you are using MSW it looks like that error is actually coming from GetSelection which is called in SetItemText when there is an active edit control to see if needs to change the text in the control too. Please enter a bug report about this and perhaps it can be fixed to not assert in this situation.
One way to work around it is to ensure that the edit control is dismissed before you call SetItemText. Another would be to catch and ignore the exception in this case, the item's text has already been changed so it should be okay.

Robin,
Thanks for replying.
I'm using Win2K with Python 2.2.2 and wxPython 2.4.0.2u.
To provide some sample code, I went to the wxTreeCtrl.py that comes with the
wxPython demo and modified the tree to make it a multi-select. Then I added
a line in the OnSelChanged() method to just set the item text on whatever
tree item is selected. When I ran it, I was unable to duplicate the problem
exactly as I had been seeing it when running my code. I did, however, get
the AssertionError when I right-clicked on a tree item (putting me into the
edit mode), then exited the edit mode by clicking either mouse button. No
exception when I exit edit mode by pressing the <Enter> key, only when I
exit edit mode by clicking either mouse button. File attached.
In your reply, you referred to dismissing an edit control. How do I do
that...by calling wxTreeCtrl::EndEditLabel()? Thanks for your help.

OK, will enter the bug.
Regarding wxTreeCtrl::EndEditLabel(), the docs for wxPython 2.4.0.2u say
that it only works with MSW. Is that still true? If so, it could be a
problem, because some of my users are using Linux. Thanks.

OK, I give up...how do I enter a bug? I clicked on "Report a bug" link on
the wxPython page, and it takes me to SourceForge. I log into SourceForge,
then I'm lost. Or I don't log into SourceForge...I'm still lost. Thanks.

Yes, but there was some discussion over the weekend about giving it an implementation for the other platforms.
