<![CDATA[QFont error]]>I have a tableview in which I import data model from database. (I have my own data model class that I subclass QSqlQuery.)
If I call this model with 5 rows with a query, it does not give a warning message.
However, if I call more than 5 records, it gives the following warning. So why ? I don't do anything with QFont.

model->setQuery(select * from users LIMIT 5 )   // no warning

model->setQuery(select * from users LIMIT 10) // warning..

its gives:
QFont::fromString: Invalid description '(empty)'

Do you get empty values with your query limited to ten results ?

Yes, you are right. This warning has disappeared for now when I fill null cells in the DB.
Thank you so much

Can you share the implementation of your custom model ?
Are you using the number 5 somewhere ?
Do you get empty values with your query limited to ten results ?
