Quoting http://tcl.tk/man/tcl8.6/TkCmd/button.htm#M16 """ pathName flash Flash the button. This is accomplished by redisplaying the button several times, alternating between the configured activebackground and background colors. At the end of the flash the button is left in the same normal/active state as when the command was invoked. This command is ignored if the button's state is disabled. """ So to see something you have to ensure that the two background colors actually differ. Complete example: import tkinter as tk root = tk.Tk() button = tk.Button(root, text="Hello") button.pack() button["activebackground"] = "red" button["background"] = "silver" root.after(1000, button.flash) root.mainloop() -- https://mail.python.org/mailman/listinfo/python-list
