QTreeWidget find parent, current item, old parent in dropEvent
-
I have a QTreeWidget that supports drop & drops. To prevent invalid drop & drops, I need to find out where the item was taken from, where it is going, and what item was taken.
Currently I do this:
@
void dropEvent(QDropEvent *event){
QTreeWidgetItem * pItem = itemAt( event->pos() );
QTreeWidgetItem * oldpItem = itemFromIndex( oldModel );//oldModel is set earlier
QTreeWidgetItem * cItem;
QString source = event->source()->objectName();
for(int i=0;i<oldpItem->childCount();i++){
QTreeWidgetItem * item = oldpItem->child(i);
if (item->text(0) == source){
cItem = item;
break;
}
}
@The current item is what I am unable to find. This approach crashes at the moment. Is there a simpler way to get what item is being moved?

Thats good question, I am exposed to this issue too. Maybe this old bug is still in play: "QTBUG-676":https://bugreports.qt-project.org/browse/QTBUG-676
