From afec4d5bb0440e290128250a176a42c459cc5b52 Mon Sep 17 00:00:00 2001 From: Shawn Rutledge Date: Mon, 19 Apr 2021 15:44:45 +0200 Subject: Store memory of grabbing agents in EventPointData QQuickDeliveryAgentPrivate::grabberAgent(event, point) was too naive: it's not only that each point could be delivered by a different agent, but also each point could have an exclusive grab in the context of one agent and multiple passive grabs in the contexts of different agents. E.g. in qtquick3d/examples/quick3d/dynamictexture, many grabs can occur if you press on a door: the View3D has a TapHandler to pick the door, so that you can click to open; each Panel has a TapHandler to defocus whichever TextArea has focus; there is a ListView for dragging through the panel delegates sideways; if you press on a yellow note, its DragHandler prepares to start dragging; etc. So at least, a TapHandler in the subscene and the other one in the View3D need to get passive grabs, and need to receive the release event in the correct coordinate system, to detect taps. When we apply the sceneTransform of a particular agent before re-delivering an update or a release, based on the grab, it has to be in the correct coordinate system for that grabber. So on grab, we use EventPointData::exclusiveGrabberContext or passiveGrabbersContext to store the pointer to the QQDeliveryAgent that was doing the delivery when the grab occurred. When we deliver the next event to a grabber, we also look up the correct DA to do the delivery. This gets done twice: once in QQuickWindow::event() to find the DAs that need to handle the event, and in QQDeliveryAgentPriv::deliverUpdatedPoints() to ignore passive grabbers for which a different DA is responsible. The failsafe "never allow any kind of grab to persist after release" is moved to QQuickWindow::event because we don't want to do it prematurely in a subscene agent, and ATM we don't require the main DA to deliver last: it depends on the order in EventPointData::passiveGrabbersContext. QQuickPointerHandler::onGrabChanged() should only be called from the relevant DA, to avoid overreaction: that is, the DA that is delivering an event at the time the grab occurs. QQDelAgentPrivate::onGrabChanged() gets called on all DA instances, but only one of them is supposed to store itself as the assigned DA for handling a particular point ID. It's not always the same as QQuickItemPrivate::deliveryAgent(): that goes astray when the same 2D subscene is mapped to the main scene and also onto multiple QQ3D models. In that case, if the user interacts directly with the 2D scene, the main DA should be assigned; or if the user interacts with one of the mapped subscenes, its DA should be assigned. We have to stop delivering to subscenes when the event is accepted, at least, because of the usual convention that delivery is done when the event remains accepted rather than being purposely ignored. So in the dynamictexture example, if you click on a TextEdit on one of the doors, it receives the event first (because it's on top) and accepts it; that stops delivery in QQuickDeliveryAgentPrivate::deliverPressOrReleaseEvent(), and now also stops QQuickWindow::event() from visiting the next subscene, or the main scene, so that the TapHandler in the View3D doesn't get clicked, and the doors don't open.
