Hi all, I'm puzzled by the 'command' option in menu and Button of Tkinter. With the following lines,
menu.add_command(label="Open Viewer", command=os.system("Open my viewer &")) Button(toolbar, text='Open Viewer', command=os.system("Open my viewer &")).pack(side=LEFT) I wanted to open a graphical viewer from the prompt (that is why I used os.system("Open viewer &")) once the user selects the option from the menu, or clicks the button, but this gets implements whenever the GUI is launched instead. Why is this? And how can I make it work? Many thanks, Joe ________________________________________________ Get your own "800" number Voicemail, fax, email, and a lot more http://www.ureach.com/reg/tag _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
