By keeping track of how many rows and cols you have and when a row or column 
becomes empty move the remaining visible items into new locations in the grid 
so that it doesn't have "holes". You could even derive a class from 
QGridLayout that does this for you automatically so that it is nicely 
encapsulated and tailored to your exact needs.
