Make Only some columns of QTreeView read only

[GAURAV PANT]

Hi,
I have a QTreeView having 10 rows and each row has 5 columns.
Now i want to make first 4 columns of each row readonly. Only the last column can be edited by the user.
How to do this. Pls help.

Reimplement flags() on the model, set the Qt::ItemIsEditable on items you want editable and clear the flag on others.

i have done this but now the row highlight color is gone.
i have MoveRowUp and MoveRowDone functions when am doing that row is not highlighted.
Only the last column which is editable is highlited

You are returning wrong flags. You should return default flags + optionally ItemIsEditable.

This is plain C++. You inherit, reimplement the flags() method and use the bit logical operations to assemble a set of bits you want active and return the from the method. You can use the base class implementation to fetch the default flags.

Qt::ItemFlags MyModel::flags(const QModelIndex &index) const {
  return QAbstractItemModel::flags(index) | Qt::ItemIsEditable; // enable ItemIsEditable for all items
}

Qt::ItemFlags MyModel::flags(const QModelIndex &index) const {
  return QAbstractItemModel::flags(index) | Qt::ItemIsEditable; // enable ItemIsEditable for all items
}
