Maybe not, but still better practice.

Then I'm not sure. Could try experimenting with the label's indent,
margin, and frameWidth.

I hope so too:-D

I just looked at that and noticed that you're implementing a
GenericDelegate. That works fine, but Qt now allows you to set row- and
column-specific delegates so having a GenericDelegate is no longer
needed. Instead, just create the delegates that you need, e.g.,
RichTextDelegate, and set that on the row(s) and column(s) its needed
for.
