qt4 - xp - model/view

[incapacitant]

I have a model called "model" attached to a TreView called "treeView.
In QT4 there was a way to empty all rows.

None of the code below gives result :

qRecap->removeRows(0, qRecap->rowCount(QModelIndex()), QModelIndex());
    qRecap->clear();

qRecap->removeRows(0, qRecap->rowCount(QModelIndex()), QModelIndex());
    qRecap->clear();

To copy to clipboard, switch view to plain text mode 

qRecap is the model.
qRecap has no member removeRows or clear.

How can i remove all entries from the model ?

What type of model is that?

- The clear() method exists for a QStandardItemModel, and should be enough to remove all items in the model.
- The removeRows() method (but not implementation, necessarily) exists for any QAbstractItemModel derivate so there is supposedly something wrong with your qRecap pointer...
