Question: add a tooltip to menu item

I'm not aware to bind to a Menu Item.

The following class MenuTooltip use the Event <Motion> to find the Menu Item if the Pointer y-Position is inside a Menu Items .yposition.

• The Tkinter Menu Widget
• Tkinter.Menu.yposition-method

classMenuTooltip(tk.Menu):
    def__init__(self, parent):
        """
        :param parent: The parent of this Menu, either 'root' or 'Menubar'
         .tooltip == List of tuple (yposition, text)
         .tooltip_active == Index (0-based) of the active shown Tooltip
         Bind events <Leave>, <Motion>
        """super().__init__(parent, tearoff=0)
        self.tooltip = []
        self.tooltip_active = None

        self.bind('<Leave>', self.leave)
        self.bind('<Motion>', self.on_motion)

    defadd_command(self, *cnf, **kwargs):
        tooltip = kwargs.get('tooltip')
        if tooltip:
            del kwargs['tooltip']
        super().add_command(*cnf, **kwargs)
        self.add_tooltip(len(self.tooltip), tooltip)

    defadd_tooltip(self, index, tooltip):
        """
        :param index: Index (0-based) of the Menu Item 
        :param tooltip: Text to show as Tooltip
        :return: None
        """
        self.tooltip.append((self.yposition(index) + 2, tooltip))

    defon_motion(self, event):
        """
        Loop .tooltip to find matching Menu Item
        """for idx inrange(len(self.tooltip) - 1, -1, -1):
            if event.y >= self.tooltip[idx][0]:
                self.show_tooltip(idx)
                breakdefleave(self, event):
        """
        On leave, destroy the Tooltip and reset .tooltip_active to None
        """ifnot self.tooltip_active isNone:
            print('leave()'.format())
            # destroy(<tooltip_active>)
            self.tooltip_active = Nonedefshow_tooltip(self, idx):
        """
        Show the Tooltip if not already shown, destroy the active Tooltip
        :param idx: Index of the Tooltip to show
        :return: None 
        """if self.tooltip_active != idx:
            # destroy(<tooltip_active>)
            self.tooltip_active = idx
            print('{}'.format(self.tooltip[idx][1]))

Usage:

class App(tk.Tk):
    def __init__(self):
        super().__init__()

        menu = MenuTooltip(self)
        menu.add_command(label='Help 1', tooltip='\tToolTip.Help 1')
        menu.add_command(label='Help 2', tooltip='\tToolTip.Help 2')
        self.menubar.add_cascade(label="Help", menu=menu)

if __name__ == "__main__":
    App().mainloop()
