Hi all , I got 2 questions for you guys.
The fist question: I wrote small Tkinter app while laerning about the Radiobutton widget, and I added a "Quit" button, like this: bb=Button(root, text="Quit", fg="BLUE", command=root.quit).pack() When I pressed the button the app crashed and I got an error message ( program is not responding ) from windows. I tried to add a frame to the program and then exit the frame, like this: bb=Button(f, text="Quit", fg="BLUE", command=f.quit).pack() But the result is the same...
Here is the full source code of the app: from Tkinter import * import sys root=Tk() f=Frame(root) text=Label(root, text="how old are you?").pack() v = IntVar(root) Radiobutton(f, text="less than 13", variable=v, value=1).pack(side=LEFT) Radiobutton(f, text="13-20", variable=v, value=2).pack(side=LEFT) Radiobutton(f, text="20-40", variable=v, value=3).pack(side=LEFT) Radiobutton(f, text="40+", variable=v, value=4).pack(side=LEFT) bb=Button(f, text="Quit", fg="BLUE", command=f.quit).pack() f.pack() root.mainloop()
This program works fine for me on Win2K. How are you running the program?
The second question: I dont understand how to get the input fron the radio buttons... It doesnt returns any value, so how can the app know what the user chose?
Read the value from the variable associated with the buttons - v. For example if you define def quit(): print 'You chose button', v.get() f.quit()
and change the command on bb to command=quit, the program will print the selection value on exit. (You have to define quit before bb or you will get a NameError.)
