Python TkinterTreectrl drag items
Ignoring the fact that this question is not the newest one - is there a specific reason why you use self.t.bind instead of self.t.notify_bind?
For me this looks pretty like the point where the Interface to tktreecrtl from Michael is not using the wrapper functionality but attempting to directly bind <Drag-begin> to a Treectrl instance which is based on tkinter.Widget
- Source Extract:
class Treectrl(tkinter.Widget):
tkinter.Widget has no possibility to find a '' event as this is generated inside tktreectrl libraries. So you get the
bad event type or keysym "Drag"
Changing to self.t.notify_bind should solve your problem.
