user interface - Enable mouse wheel in Spinbox Tk Python -

i wondering if there smart way of enabling mouse wheel in tk widget 'spinbox' in python.

the sensible solution found far derive new spinbox class wanted functionality:

class spinbox(tk.spinbox):     def __init__(self, *args, **kwargs):         tk.spinbox.__init__(self, *args, **kwargs)         self.bind('<mousewheel>', self.mousewheel)         self.bind('<button-4>', self.mousewheel)         self.bind('<button-5>', self.mousewheel)      def mousewheel(self, event):         if event.num == 5 or event.delta == -120:             self.invoke('buttondown')         elif event.num == 4 or event.delta == 120:             self.invoke('buttonup') 

but given expected behavior, suspecting there better solution.
