[Tkinter-discuss] pack equivalent of grid_remove(), eg. pack_remove() ?

Hi,

Thus spoketh python at bdurham.com 
unto us on Thu, 09 Dec 2010 09:25:33 -0500:

There's nothing like that built in, but it is quite easy to set it up:


from Tkinter import *
root = Tk()
root.geometry('200x200')

class pFrame(Frame):
    def __init(self, *args, **kw):
        Frame.__init__(self, *args, **kw)
        self._packinfo = {}

    def pack(self, *args, **kw):
        Frame.pack(self, *args, **kw)
        self._packinfo = self.pack_info()
    pack_configure = pack

    def pack_recall(self):
        self.pack(**self._packinfo)


f = pFrame(root, bg='yellow')
f.pack(fill='both', expand=1)
f.pack_forget()
f.pack_recall()

root.mainloop()

I hope this helps

Michael
