Show all available bindings for given widget

[Larz60+]

I needed to know available bindings for a ttk Notebook widget, and had a hard time finding them
This class will show available bindings for any widget:

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19

class WidgetBindings:     def __init__(self, wobject):         instance = wobject()         self.process(instance)         instance.destroy()       @staticmethod     def process(instance):         bindings = set()         for bindtag in instance.bindtags():             bindings |= set(instance.bind_class(bindtag))         for item in bindings:             print(item)     if __name__ == '__main__':     import tkinter.ttk     print('ttk.Notebook bindings')     WidgetBindings(tkinter.ttk.Notebook)

Output:
ttk.Notebook bindings
<Destroy>
<Control-Shift-Key-Tab>
<Key-Right>
<Control-Key-Tab>
<Button-1>
<Key-Left>
<Destroy>
<Control-Shift-Key-Tab>
<Key-Right>
<Control-Key-Tab>
<Button-1>
<Key-Left>
<Destroy>
<Key-F10>
<<PrevWindow>>

<KeyRelease-Alt_L>
<Key-Alt_R>
<Button-1>
<Key-Left>

<Alt-KeyRelease>
<<NextWindow>>
<KeyRelease-Alt_R>
<Control-Shift-Key-Tab>
<Key-Right>
<Control-Key-Tab>
<Key-Alt_L>
