How to center the button before drawing it?

I am trying to set position of button in the center of my GUI window:

capture_button = Button(self, text="Capture", command=self.client_exit)
capture_button.place(x=100, y=100)

But there is a problem - button's centre is not at (100,100) but its left top corner is at (100,100) so there is no symmetry. So I decided to do something like that:

capture_button.place(x=100+buttonsize.x/2, y=100 - buttonsize.y/2)

I know that I can use 

capture_button.winfo_width

but that works after first draw - how can I do this before drawing, just in ctor of python class? Or there are other ways like setOrigin(centre) and then setting position?

If your real goal is simply to center the button using place, you can use relative coordinates instead of relying on computing the width of the button.

capture_button.place(anchor="c", relx=.5, rely=.5)
