import Tkinter
import tkMessageBox
def askyesno():
if tkMessageBox.askyesno("Testing Askyesno",
"Click on something!"):
print 'You clicked on Yes!';
rootWindow = Tkinter.Tk()
button1 = Tkinter.Button(rootWindow,
text="Askyesno",
command=askyesno)
button1.pack()
button2 = Tkinter.Button(rootWindow,
text="QUIT",
command=rootWindow.quit)
button2.pack()
rootWindow.mainloop()
I wrote a script similar to the one shown above. Here are my questions:
1) If I import my script above for the first time, my script runs fine.
However, after I quit my script and try to reload my script at the
Python interpreter by typing reload(myscriptname), I get the error
message: "TclError: Can't invoke "frame" command:". Actually, it is
quite a long-winded error message, I'm just giving the last line.
What's going on and how do I fix this?
2) I even tried including a frame in def askyesno(), like this:
frame1 = Tkinter.Frame(rootWindow)
if tkMessageBox.askyesno("Testing Askyesno",
"Click on something!"):
print 'You clicked on Yes!';
frame1.pack()
However, I still get the same problem. I'm using Tkinter for the first
time and this "Can't invoke "frame" command" error message has been
frustrating me tremendously whenever I try to use one of tkMessageBox's
standard dialogs. I must be doing something wrong, and I would
appreciate it if someone could give some pointers on how to use
tkMessageBox.
3) Also, how do you quit a Tkinter script? Whenever I try to close a Tk
window, I can't get back to the Python interpreter ">>>" prompt.
Instead, my Python shell hangs and I have to do a CTRL-ALT-DEL and
end-task. Surely, there are better ways of closing a Tk window.
I'm running Windows 95 on a Pentium class computer. My Python
interpreter is version 1.5.2 and my Tcl/Tk interpreter is the same one
that is installed automatically by the Python 1.5.2 installer.
Thanks in advance.
