Since the feature is not documented anywhere it might also be a good idea to wrap this into a try...except. See this little code snippet: ############################################# from Tkinter import * import tkFileDialog as tkfd root = Tk() try: # call a dummy dialog with an impossible option to initialize the file # dialog without really getting a dialog window; this will throw a # TclError, so we need a try...except : try: root.tk.call('tk_getOpenFile', '-foobarbaz') except TclError: pass # now set the magic variables accordingly root.tk.call('set', '::tk::dialog::file::showHiddenBtn', '1') root.tk.call('set', '::tk::dialog::file::showHiddenVar', '0') except: pass # a simple callback for testing: def openfile(event): fname = tkfd.askopenfilename() print(fname) root.bind('<Control-o>', openfile) root.mainloop() ############################################# Best regards Michael _______________________________________________ Tkinter-discuss mailing list Tkinter-discuss@python.org https://mail.python.org/mailman/listinfo/tkinter-discuss ------- End of Forwarded Message _______________________________________________ Tkinter-discuss mailing list Tkinter-discuss@python.org https://mail.python.org/mailman/listinfo/tkinter-discuss
