I've created a menubar in Python 3, and I'm wondering how to add keyboard shortcuts and accelerators to it. Like hitting "F" for File Menu and whatnot.
Through some digging around I found the "underline=" attribute, but it doesn't seem to work in Python 3. It didn't work when I tried it, and the only documentation I found for it was for earlier versions of Python.
menubar = Menu(master)
filemenu = Menu(menubar, tearoff=0)
menubar.add_cascade(label="File", underline=0, menu=filemenu)
consider reading (http://effbot.org/tkinterbook/tkinter-events-and-bindings.htm)
you have to bind your widget to an event to your function:
Keyboard events are sent to the widget that currently owns the keyboard focus. You can use the focus_set method to move focus to a widget:
Capturing keyboard events
from Tkinter import * root = Tk() def key(event): print "pressed", repr(event.char) def callback(event): frame.focus_set() print "clicked at", event.x, event.y frame = Frame(root, width=100, height=100) frame.bind("<Key>", key) frame.bind("<Button-1>", callback) frame.pack() root.mainloop()
If you run this script, you’ll find that you have to click in the frame before it starts receiving any keyboard events.
I followed this guide to implement a ctrl+f binding to one of my functions a while ago:
toolmenu.add_command(label="Search Ctrl+f", command=self.cntrlf) root.bind('<Control-f>', self.searchbox) def cntrlf(self, event): self.searchbox()
for your file menu, you might want to consider implementing accelerators:
menubar.add_cascade(label="File", menu=fileMenu) fileMenu.add_command(label="Exit", command=quit, accelerator="Ctrl+Q") config(menu=menubar)
for Menu options remember to use ALT followed by the first letter of the OptionName
file Menu = ALT followed by f Tool Menu = ALT followed by t and so on
hope this provides usefull
