How to set data type in a column

[jss193]

Hello,

I do not really know if its possible to do what I wish, what I want is to set different data types in a QAbstracItemModel for each column, for example, I want to Column 1 only accepts int values, column2 QString and so on...

Is this possible?

Thank you!

You implement that yourself via https://doc.qt.io/qt-5/qabstractitemmodel.html#setData.

If you allow UI editing and want to control the input widget to correspond to the column type, you can use https://doc.qt.io/qt-5/qabstractitemview.html#setItemDelegateForColumn and https://doc.qt.io/qt-5/qabstractitemdelegate.html#createEditor, or https://doc.qt.io/qt-5/qdatawidgetmapper.html#setItemDelegate, to achieve that to match your model column types.

Qt classes do not offer "out-of-the-box" support for column types.
