The answer is correct, however I think that in general it is wrong to 
set the geometry like this. grid and pack compute the necessary space 
for the window themselves, which adapts to the length of labels on 
buttons etc. In all GUI programs I've written, the only place to set 
window sizes in pixels have been canvas widgets, which do not have a 
native size derived from the content. Setting the size on the toplevel, 
and in absolute numbers, i.e. not computed from other sizes, is likely 
to lead to problems on different platforms, font sizes or theme changes.
