Is there any way to set some of the colums of my model to not be editable ?
Also my second column contains double variables. When you click to it you get a QDoubleSpinBox but it only allows 2 decimals ! How can i change that to lets say 5 ?

Yes, reimplement QAbstractItemModel::flags() for your model and make sure ItemIsEditable is not returned for indexes from those columns.

Reimplement either QAbstractItemDelegate::createEditor() or QAbstractItemDelegate::setEditorData().

Hi Wysota,

Sorry to bug you, but I've been trying to use a QtreeView with checkboxes enclosed for each item with not much progress. I followed some thread in the forum and reimplement the flags method in my model class to include ItemIsUserCheckable. Now I can see the checkboxes appear next to each item in the tree. However, I cannot check or uncheck the checkboxes at all. I see some people advice that I should implement the setData() method in my model class but I have no clue on how to do that. Could you shed some light here?

Thanks a lot
