Tkinter how to bind to shift+tab
The following code (in python 2.7.6) should make it clear:I hope this reference works for you
from Tkinter import *def key(event=None): print 'You pressed Ctrl+Shift+Tab'root = Tk()frame = Frame(root, width=100, height=100)frame.focus_set()frame.bind('<Control-Shift-KeyPress-Tab>', key)frame.pack()root.mainloop()
EDIT: The above works well for Windows and Mac. For Linux, use
'<Control-ISO_Left_Tab>'.
Not a direct answer and too long for a comment.
You can solve your question by yourself with a simple trick, bind <Key>
to a function, and print the key event argument passed to the bind
function where you can see which key is pressed or not. Try multiple combinations of keys to see what is the state
and what is their keysym
or keycode
.
import tkinter as tkdef key_press(evt): print(evt)root = tk.Tk()root.bind("<Key>", key_press)root.mainloop()
It will output the following for pressing SHIFT + TAB combo on macOS.
<KeyPress event state=Shift keysym=Tab keycode=3145753 char='\x19' x=-5 y=-50>
Where,
state=Shift
means a key event's state is on SHIFT.keysym=Tab
means tab key is pressed. If we just press SHIFT, thekeysym
will be Shift_L or Shift_R (shows Shift_L for both shift keys on mac).keycode
is an unique code for each key even for different key combos for example keycode for Left Shift is131330
and keycode for TAB is3145737
but when SHIFT + TAB is pressed the code is not the same to either, it is3145753
. (I'm not sure if these are the same code for every os but one can figure it out by printing them to the console)Also, see all the event attributes.
Though bind '<Shift-Tab>'
key combination works well on Mac, it can also be used like so...
def key_press(evt): if evt.keycode==3145753: print('Shift+Tab is pressed')
