I just wanna set the font to bold/not-bold when clicking on a row in
QTableView.
With a QTableWidget I do it like this:
font = QFont()
font.setBold(True) or False
QTableWidget.item(row,col).setFont(font)
But the QTableView has data/view 'models' attached to it and that syntax
doesn't work:
Tried:
font = QFont()
font.setBold(True) or False
model = QTableView.model()
model.setFont(model.index(row,col), font)
Throws AttributeError: 'QSqlTableModel' object has no attribute 'setFont'
This doesn't throw an error, but doesn't show bold:
model.setData(model.index(tblRow, col), font, Qt.FontRole)
Any ideas?
You definitely need to be setting the font in an item. I'm not sure but
I think that your QFont() doesn't have any properties, so it doesn't do
anything. I found this bit in a page - it's in C++ instead of Python
but that doesn't really make a difference except for the exact syntax to
use -
https://forum.qt.io/topic/70016/qlistview-item-font-stylesheet-not-working/4
QVariant v = ModelBaseClass::data(index,role);
if( condition && role == Qt::FontRole )
{
QFont font = v.value();
font.setBold( true );
v = QVariant::fromValue( font );
}
IOW, you have to get the font from the item, then set it to bold, which
you would do with setFont(). Then you set that new font on the item. Of
course you would have to unset bold on it later. See
https://doc.qt.io/qt-6/qtablewidgetitem.html#font
Instead of "item", you might need to operate on "row". I didn't look
into that. Since a row probably doesn't have just one font (since it
can have more than one item), you'd still have to get the font from some
item in the row.
You might also be able to make the item bold using CSS, but I'm not sure.
Thanks
Internet searches are your friend for questions like this. I've never
worked with a QTableView, so I had to start with some knowledge about
some other parts of QT. I found the first page searching for "qt set
qtableview row font", and the second searching for "qtablewidgetitem".

Crafting Software (PUG practical meeting)
Wed, 2 Nov 2022 at 1830~2030 NZDT (0530~0730 UTC) Come to our Coding Evening with your Python questions, suggestions, problems, etc; and/or bring a Lightning Talk about your current topic-of-interest - something new, a recent discovery, a contribution you have made... Thereafter, we will continue the Crafting Software series. These are code-along-at-home exercises. The initial sessions were designed for Beginners, and have gradually 'grown' into areas which will challenge and benefit Journeyman Python Programmers and even Masters. The aim is to complement our Software Craftsmanship Presentation series with practical coding and observing the advantages of craftsmanship, as we/the code becomes more sophisticated. We are enjoying meeting attendees from all over the world (Europeans invert their screens to be able to see us 'right way up' (!?)) Please RSVP to be advised of the web-conference URL, and QuickStart Guide. https://www.meetup.com/nzpug-auckland/events/hgxmwsydcpbdb/ -- Regards, =dn Auckland Branch, New Zealand Python Users' Group -- https://mail.python.org/mailman/listinfo/python-list

This looks like a useful tutorial -
