You should double check the architecture anyway. I would also start with a shared build of Ogre as it often is easier to link to.

@blossomsg The explanation is simple: QSpinBox expects an integer but your model appears to be a list of strings causing the error. Correct for data type agreement. By example change to: self.data.insert(position, [0, 0, 0, 0, 0])

It shows nothing in the cell because there is nothing in the database. If you would like to customise that behaviour you can do it with a QStyledItemDelegate. Something like: MyDelegate::displayText(const QVariant &value, const QLocale &locale) const { if (value.isNull()) { return QStringLiteral("{null}"); else return QStyledItemDelegate::displayText(value, locale); } but you can get much more fancy if you need to. You should consider what happens if the database column actually contains the string "NULL" or "{null}" or whatever placeholder you use.

Hi, If it's using PyQt or PySide it should be translatable in C++. That said, can you explain your use case ?

Hi, How are you starting your new project ? Qt Creator ? Command line ?

@debian said in ld: cannot find atomic: How can I fix this is? Install the libatomic library package.
