Tkinter：将相同的键绑定到不同的小部件

Question

Is there a way to bind the same key to two different widgets in Tkinter?

Answer 1

Sure there is. Just bind it to two different widgets.

import Tkinter
root = Tkinter.Tk()

def keypress1(event):
    print event.keysym, " key pressed in root"

def keypress2(event):
    print event.keysym, " key pressed in text"

text = Tkinter.Text(root, width=20, height=20)
root.bind("<Return>", keypress1)
text.bind("<Return>", keypress2)
text.pack()

root.mainloop()

Of course, the event has to actually occur in both widgets. I'm not sure whether there's a way to propagate an event captured by one widget to another that didn't capture it. But there are probably better ways to solve your problem than propagating events that way; you can always catch the event in root and do whatever you want there.
