I would imagine that the checkbox that you assign is trying to fill up the
full space given to it, and for some reason the space seem left-aligned.
If you were to composite the checkbox within another QWidget, put the
checkbox in a layout for the QWidget, and use
layout.setAlignment(Qt.AlignCenter | Qt.AlignCenter) the QWidget should
fill up the full space, whilst the checkbox should land in the center of
the QWidget. Don't forget to remove contentsMargins of the layout as well.
layout.setContentsMargins(0, 0, 0, 0)
A neat trick to debug these scenarios is to assign a temporary in-code
stylesheet.
my_widget.setObjectName('DebugTest')
my_widget.setStylesheet("#DebugTest {background-color: blue}")
Example delegate method:
checkbox = QCheckBox()
container = QWidget()
layout = QHBoxLayout(container)
layout.addWidget(checkbox)
layout.setAlignment(Qt.AlignCenter | Qt.AlignCenter)
layout.setContentsMargins(0, 0, 0, 0)
# Here is where you return your container, rather than the checkbox
directly.
return container
*Edit*: After having actually looked at the example you posted, this is the
way he does it too. :)
