The same in OO manner:
<lang python>
class ClickCounter(tk.Frame):
def click(self):▼
def
self.label['text'] = 'Number of clicks: %d' % self.count▼
tk.Pack.config(self)
▲ self.label = Label(self, text='here have been no clicks yet')
self.label.pack()
self.button = tk.Button(self,
text='click me',
command=self.click)
self.button.pack()
▲ Frame.__init__(self, master)
self.createWidgets()▼
self.count = 0
▲ def click(self):
▲if __name__=="__main__":
▲ ClickCounter().mainloop()</lang>
if __name__ == "__main__":
ClickCounter().mainloop()
</lang>
