From 96ec0ab8f0b2e53eff6e1887aff7e51601821845 Mon Sep 17 00:00:00 2001 From: Shawn Rutledge Date: Mon, 20 Nov 2017 14:01:12 +0100 Subject: QQuickList/GridViewPrivate::fixupPosition: don't set moveReason In QQuickItemViewPrivate::applyModelChanges(), if moveReason = QQuickItemViewPrivate::Other, then QQuickItemView::trackedPositionChanged() will fail to call d->setPosition(pos), which is normally what keeps the Flickable moving for a while. Leave the reason as-is (it will be SetIndex in this case), so as not to forget that we were actually trying to move down when the sequence window->polishItems() -> QQIV::updatePolish() -> layout() -> fixupPosition() did its part of the work of moving down.

If we regenerate or clear the whole view in the mean time, the bufferedChanges become just as invalid as the currentChanges. On top of that, refilling can trigger further changes, part of which will be applied during the refilling. As that leaves us in an inconsistent state, we need to loop the refilling until no further changes are generated. As the changes might affect items that are already visible, and therefore not subject to refilling, we need to clear all the items before refilling in this case. In QTBUG-46488 things are added in the onCompleted callback of the delegates (by expanding the tree view, which translates into adding rows to the list view). Depending on where you add the new items, the list view might pick them up when iterating the model on refill() or it might create delegates for the same model entry twice. So, if that happens we need to discard the result and refill again.
