Hi thanks to all who replied.
I might consider using a QToolButton if I want to put in an icon. And
by setting the widget's size policy to fixed I found that it actually
uses more width than is needed (for whatever reason) thereby not
making the radios uniformly spaced horizontally vs vertically.
I ended up writing:
refPtWidget = QWidget ( window )
refPtGrid = QGridLayout ( refPtWidget )
refPtGrid . setHorizontalSpacing ( 0 )
refPtGrid . setContentsMargins ( 0, 0, 0, 0 )
refPtArray = 
for i in range ( 3 ) :
rowArray = 
for j in range ( 3 ) :
button = QRadioButton ()
rowArray += [ button ]
refPtGrid . addWidget ( button, i, j )
refPtArray += [ rowArray ]
radioHeight = refPtArray [ 0 ] [ 0 ] . sizeHint () . height ()
refPtWidget . setFixedSize ( radioHeight * 3, radioHeight * 3 )
I suppose I can achieve lesser spacing between the painted than this
by hardcoding some negative spacing or something, but I didn't want to
(as it may cause clipping depending on the margin the sizeHint
provides around the drawn button) and I just respected the sizeHint of
