Hi there,
I have QAbstractItemModel and displaying its data in a QTableView.
A derived QStyledItemDelegate class creates an QSpinBox to edit values in
column 1.
A QSpinbox on some other place on the widget where the QTableView is nested,
shows the same data eg. (2/1), the QSpinbox is connected through QWidgetMapper.
Actually it works fine: I can change both value and they update each other if
I change the focus.
But thats the point! The changed values have to immediately update the model
data. How can I force that the valueChange() signal update the model data.

Therefore if I insert a number directly in the spinbox and press enter,
the number jumps back to the old value. Only the up/down button works to edit
the value.

Thanks for help
