Hi,
I want to use multi font in QTableview so created my newclass (QSqlRelationalTableModel
with virtual QVariant data(const QModelIndex & index, int role = Qt:
isplayRole) const)
Now each row can change the font I want. but when I select and change data with ItemDelegate (Dropdown List) and click next cell. new selected data is only shown id (key). (please see picture Style col's row 1 only show 4.
But I submit, refresh and data is save and table is correct.
1. How can I fix it?
2. I want to change delegate list's font according to cell's font. How can I do it?
Thanks.
