So you override Tkinter.Tk() ? If yes, it should be possible to override
mainloop() as well. In fact all widgets share the same mainloop() method
defined in Tkinter.Misc, which is very easy to override:
import Tkinter
class Tk(Tkinter.Tk):
def __init__(self, *args, **kw):
Tkinter.Tk.__init__(self, *args, **kw)
def mainloop(w, n=0):
# your code here...
print 'Running mainloop through widget', w._w
self.tk.mainloop(n)
Tkinter.Misc.mainloop = mainloop
root = Tk()
b = Tkinter.Button(root, text='quit', command=root.quit)
b.pack(padx=100, pady=100)
b.focus_set()
b.mainloop()
Regards
Michael
