Answer 1

Could you do something like create the grid of buttons up front, but include a hidden button in the blank space? Then when the button is clicked hide the clicked one and display the hidden one. Then you don't have to worry about moving buttons around, unless you need the actual button object to move for some reason.

Edit to enhance answer from comments:

Below is a simple example of hiding a button and it shows how to track the buttons as well, unless I screwed up moving it to the editor. This can be translated to a list or dictionary of buttons or whatever need be. You'd also need to determine find a way to register the local buttons or add some context to know which one to show or hide.

from Tkinter import Button, Frame, Tk


class myButton(Button):

    def __init__(self, *args, **kwargs):
        Button.__init__(self, *args, command=self.hideShowButton,
                        ** kwargs)
        self.visible = True

    def hideShowButton(self):
        self.visible = False
        self.pack_forget()

window = Tk()
frame = Frame(window)
frame.pack()
b1 = myButton(window, text="b1")
b1.pack()
b2 = myButton(window, text="b2")
b2.pack()
b3 = myButton(window, text="b3")
b3.pack()
window.wait_window(window)
print "At the end of the run b1 was %s, b2 was %s, b3 was %s" % (str(b1.visible), str(b2.visible), str(b3.visible))
