I am trying to use drag and drop to reorder the rows in a QTableView with a single column I searched and found things about setting the QTableView options and the model flags:
QAbstractTableModel:
def flags(self, index=None):
return Qt.ItemIsSelectable | Qt.ItemIsEnabled | Qt.ItemIsEditable | Qt.ItemIsDragEnabled | Qt.ItemIsDropEnabled
QT Designer set QTableView:
self.tableViewList = QTableView(DialogList)
self.tableViewList.setObjectName(u"tableViewList")
self.tableViewList.setGeometry(QRect(10, 50, 521, 301))
self.tableViewList.setDragEnabled(True)
self.tableViewList.setDragDropOverwriteMode(False)
self.tableViewList.setDragDropMode(QAbstractItemView.InternalMove)
self.tableViewList.setDefaultDropAction(Qt.MoveAction)
self.tableViewList.setSelectionMode(QAbstractItemView.SingleSelection)
self.tableViewList.setSelectionBehavior(QAbstractItemView.SelectRows)
self.tableViewList.horizontalHeader().setStretchLastSection(True)
I can see the drag happening but I get the prohibited (slashed red circle) icon for the drop, and the drop does not happen.
Any hints on how to correct this? I saw in searches that the item (model flags) needs to needs to be drop disabled, but that does not make sense to me since I want to drop it. I did try ~Qt.ItemIsDropEnabled but that did not make any difference.
I saw other searches which pointed to moveRow and moveRows. Since I subclassed QAbstractTableView, do I need to implement those methods?
