QAbstractItemView clipboard behaviour

Classes derivated from QAbstractItemView won't let copy item data to the clipboard using CTRL+C if the data is not of type QVariant::String. For example it is not possible to copy data from a sql model if column type is numeric. Have a look at the KeyPressed method.

QAbstractItemView should be able to copy any data to the clipboard, which can be converted to QString , not only QVariant of type string.
