[Interest] Change QCheckBox to QPushButton in a QTableView

[Tony Rietwyk]

Hi Jason,

You'll have to initialise quite a bit more in the QStyleOptionButton 
button than just the text - especially the inherited rect member.   
Maybe QStyleOption.initFrom can help, or create an override class on 
QPushButton to expose its initStyleOption.

Hope that helps, Tony
