Drag&Drop with QStandardItemModel

Hi,
I have a QListView, which is linked to a QStandardItemModel. I'd like to be able to drop files on that QListView. The problem is, the supportedDropActions method is not supported by this object. This is quite strange, since it inherits QAbstractItemModel which provides this function. Is there a way to do drag & drop with QStandardItemModel ?
Thanks in advance

Subclass QStandardItemModel and reimplement the desired method. BTW. "supportedDropActions" returns Qt::CopyAction by default. So you should be able to drop data on it. Maybe you didn't enable dropping in the view?

Hi. Thanks for your answer.
Actually, that's more the supportedDropActions which is intersting me, if I subclass QStandardItemModel, what should be the constructor ? Is this correct ? (I'm usually a C coder) :

Code:

---

#include <QtGui>
 
class PeerListModel : public QStandardItemModel {
	Q_OBJECT
public:
	PeerListModel (QWidget *parent = 0);
};
 
PeerListModel::PeerListModel (QWidget *parent = 0) {
	QStandardItemModel(this);
}

Not quite, it should be:

Code:

---

#include <QStandardItemModel>
 
class PeerListModel : public QStandardItemModel 
{
   Q_OBJECT
   public:
      PeerListModel( QObject *parent = 0 );
};
 
PeerListModel::PeerListModel( QObject *parent ) : QStandardItemModel( parent ) 
{
}

Remember that if the constructor's implementation is in a header file, you should add "inline" keyword in front of it.

Hi,
actually it is not in the header file, I just pasted both files merged.
Anyway, your solution works just great
Once again, thank you a lot for your help :)
