[wxPython-users] Re: problem getting correct treeCtrl item id

[Jeff Peck]

Jeff,
  Just a shot in the dark, but in the code to OnMenuItem you are calling 
GetItemSelection() - shouldn't that be GetSelection()?

>> hello, I am using the below code to add items to a treeCtrl. I have teh user create a new folder to which they can add items. If they right click on the folder a popup menu appears with an option to add a new item to the folder they just created. so it all works ok except that the tree item id that I saved (self.new_item) isn't the same as the one I get when I select the item using GetSelection(). Shouldn't they be the same? thanks.
