Getting keyboard events while in a drag and drop state

[gerrysweeney]

Hi,

Yes I am fine with C++, but I am new to Qt. I have already tried what you suggest. I am dragging from a QListWidget derived class to a QGraphicsView derived class. In my code I have the following: -

class EdaSymbolListWidget : public QListWidget
{
protected:
    void startDrag(Qt::DropActions /*supportedActions*/)
    {
        QListWidgetItem *item = currentItem();
        QMimeData *mimeData = new QMimeData;
        QByteArray ba;
        ba = item->text().toLatin1().data();
        mimeData->setData("application/x-my-custom-item", ba);
        QDrag *drag = new QDrag(this);
        drag->setMimeData(mimeData);
 
        drag->exec(Qt::MoveAction);
    }
 
 
    void keyPressEvent(QKeyEvent *key)
    {
        qDebug("EdaSymbolListWidget Key Event: %x", key->key());
 
        QListWidget::keyPressEvent(key);
    }
 
};

class EdaSymbolListWidget : public QListWidget
{
protected:
    void startDrag(Qt::DropActions /*supportedActions*/)
    {
        QListWidgetItem *item = currentItem();
        QMimeData *mimeData = new QMimeData;
        QByteArray ba;
        ba = item->text().toLatin1().data();
        mimeData->setData("application/x-my-custom-item", ba);
        QDrag *drag = new QDrag(this);
        drag->setMimeData(mimeData);

        drag->exec(Qt::MoveAction);
    }


    void keyPressEvent(QKeyEvent *key)
    {
        qDebug("EdaSymbolListWidget Key Event: %x", key->key());

        QListWidget::keyPressEvent(key);
    }

};

To copy to clipboard, switch view to plain text mode 

I also have the following override in my QGraphicsView derived class

void MyGraphicsView::keyPressEvent(QKeyEvent *key)
{
    qDebug("View Key Event: %x", key->key());
 
    QGraphicsView::keyPressEvent(key);
}

void MyGraphicsView::keyPressEvent(QKeyEvent *key)
{
    qDebug("View Key Event: %x", key->key());

    QGraphicsView::keyPressEvent(key);
}

To copy to clipboard, switch view to plain text mode 

When I focus the list or view I get the key presses in the debug window as I would expect. However, once a start a drag operation from the QListWidget pressing keys no longer calls the keyPressEvent in either view, and thats where I am stuck
