QTableView does not query all roles for a column

[lotek]

Hello,

For all but one (column 2) QTableView columns, the view queries the model for 7 different roles - 8,6,7,9,10,1,0. That is OK.
For one column (column 2) only one role (0) is queried. See the data() call dump below.

I can't remember that I did anything special with this column. What could be the cause?

THX for any hint

qDebug() << "data " << modelIdx << "role " << role;

What is the value of the row 0 col 2 cell? A null QVariant() perhaps? If there is nothing to display then you don't need the font, text alignment, text colour, check state etc.
