Cristian, You have to bind your Alt key presses separately. The underline= only underlines the letter - it does not bind to an event handler.
Here's a snippet that may give you some ideas. Disclaimer: I'm not sure if its best practice or not. Malcolm """ Treat Alt+I as a shortcut keystroke for the Insert button """ import Tkinter as tk import ttk def onClick( event=None ): if event: print event.keysym, event.keysym_num, event.state # event.state == 131104 regardless of left or right alt key if event.keysym == 'i' and event.state == 131104: pass else: return button1.focus_set() entry1.delete( 0, 'end' ) entry1.insert( 'end', '<Open clicked>' ) root = tk.Tk() style = dict( padx=24, pady=24 ) entry1 = tk.Entry( root ) entry1.pack( **style ) entry2 = tk.Entry( root ) entry2.pack( **style ) button1 = ttk.Button( root, text='Insert text', underline=0, command=onClick ) button1.pack( **style ) # bind shortcut keystrokes at the outermost container root.bind( '<Key>', onClick ) root.mainloop() _______________________________________________ Tkinter-discuss mailing list Tkinter-discuss@python.org http://mail.python.org/mailman/listinfo/tkinter-discuss
