dropping on on a QListWidget
Message 1 in thread
What do you have to do to get a QListWidget to accept drag enter
events/drops? Shouldn't I just implement supportedDropActions() and
dragEnterEvent? In the following dragEnterEvent is never called...
Qt::DropActions LibraryListWidget::supportedDropActions() const
{
return Qt::ActionMask;
}
void LibraryListWidget::dragEnterEvent(QDragEnterEvent *e)
{
qDebug("enter");
e->accept();
}
thanks

In constructor, you can set:
setDragEnabled(true);
setAcceptDrops(true);
setDropIndicatorShown(true);
Then, implement:
protected:
void dragEnterEvent(QDragEnterEvent *event);
void dragMoveEvent(QDragMoveEvent *event);
void dropEvent(QDropEvent *event);
void startDrag(Qt::DropActions supportedActions);
It should work.
