Why do you try to use a QCheckBox in the first place? Just return the
Qt::IsUserCheckable flag in flags() and react to the Qt::CheckStateRole
in data() for the apropriate column. Then the view itself will add a
checkbox to the column and display the text from data(). Works like a
charm.

Anyway, some comments...

This is wrong, you're misuing the standard item model. Please read its
API docs, its usually not needed to subclass it, you only need to create
QStandardItem's for the various cells in your model and set them
checkable if they should be checkable.

If you want to write your own model, because you have some custom/legacy
data format use QAbstractTableModel as base (when its tabular data) or
QAbstractItemModel (if its tree-like data).
