[Solved] overloading dropEvent

[countzero]

I am working on a simple window app. I have two qlistwidgets and I want to overload the dropEvent for one of them.
@namespace Ui {
class MainWindow;
}

class MainWindow : public QMainWindow {
Q_OBJECT
public:
MainWindow(QWidget *parent = 0);
~MainWindow();

protected:
void changeEvent(QEvent *e);
virtual void dropEvent(QDropEvent *e);

private:
Ui::MainWindow *ui;

private slots:
void on_createString_clicked();
};@

Ui::MainWindow *ui; is the main class that contains all the widgets. the ui_window.h file is generated by qtcreator.

All the examples that I have seen put the function void dropEvent in the "your class" header file(the code above).

I have tried this but it does not seem to work. It seems like I am doing this a level to high, but I don't know where to put it since you should not edit the ui_window.h because it will get overwritten the next time you do something in qtcreator.

Any help would be great.
Thanks

I think you could try this ..

Extend QListWidget and override the dropEvent. Then in your designer, promote the QListWidget to the new class you created. That should work

I have created a new class and promoted my QListWidget to the new class but now it does not appear when I run the program. It is viewable in UI designer and the following code is generated.
@
CustomProtocol = new CustomListWidget(centralWidget);
CustomProtocol->setObjectName(QString::fromUtf8("CustomProtocol"));
CustomProtocol->setGeometry(QRect(440, 20, 300, 275));
CustomProtocol->setDragEnabled(true);
CustomProtocol->setDragDropMode(QAbstractItemView::DragDrop);
CustomProtocol->setDefaultDropAction(Qt::MoveAction);
@

Does the constructor the new class need anything? It is currently blank.

Thanks,

hope "this wiki page":http://developer.qt.nokia.com/wiki/Custom_QListWidget helps

Thanks I figured it out. I missed the : QListWidget(parent) so it was not inheriting the correct functions.
