33+

34+/*

35+ Where the ownership of touches is registered.

36+

37+ Singleton used for adding a touch point ownership model analogous to the one

38+ described in the XInput 2.2 protocol[1] on top of the existing input dispatch logic in QQuickWindow.

39+

40+ It provides a much more flexible and powerful way of dealing with pointer ownership than the existing

41+ mechanisms in Qt. Namely QQuickItem::grabTouchPoints, QuickItem::keepTouchGrab,

42+ QQuickItem::setFiltersChildMouseEvents, QQuickItem::ungrabTouchPoints and QQuickItem::touchUngrabEvent.

43+

44+ Usage:

45+

46+ 1- An item receives a a new touch point. If he's not sure whether he wants it yet, he calls:

47+ TouchRegistry::instance()->addCandidateOwnerForTouch(touchId, this);

48+ touchEvent->ignore();

49+ Ignoring the event is crucial so that it can be seen by other interested parties, which will

50+ behave similarly.

51+

52+ 2- That item will then start receiving UnownedTouchEvents for that touch from step 1. Once he's

53+ made a decision he calls either:

54+ TouchRegistry::instance()->requestTouchOwnership(touchId, this);

55+ If he wants the touch point or:

56+ TouchRegistry::instance()->removeCandidateOwnerForTouch(touchId, this);

57+ if he does not want it.

58+

59+ Candidates are put in a priority queue. The first one to call addCandidateOwnerForTouch() will

60+ take precedence over the others for receiving ownership over the touch point (from now on called

61+ simply top-candidate).

62+

63+ If the top-candidate calls requestTouchOwnership() he will immediately receive a

64+ TouchOwnershipEvent(gained=true) for that touch point. He can then safely call

65+ QQuickItem::grabTouchPoints to actually get the owned touch points. The other candidates

66+ will receive TouchOwnershipEvent(gained=false) and will no longer receive UnownedTouchEvents

67+ for that touch point. They will have to undo whatever action they were performing with that

68+ touch point.

69+

70+ But if the top-candidate calls removeCandidateOwnerForTouch() instead, he's popped from the

71+ candidacy queue and ownership is given to the new top-most candidate if he has already

72+ made his decision, that is.

73+

74+ The TouchRegistry cannot enforce the results of this pointer ownership negotiation (i.e.,

75+ who gets to grab the touch points) as that would clash with QQuickWindow's input event

76+ dispatching logic. The candidates have to respect the decision and grab the touch points

77+ themselves.

78+

79+ If an item wants ownership over touches as soon as he receives the TouchBegin for them, his step 1

80+ would be instead:

81+ TouchRegistry::instance()->requestTouchOwnership(touchId, this);

82+ return true;

83+ He would then be notified once ownership has been granted to him, from which point onwards he could

84+ safely assume other TouchRegistry users wouldn't snatch this touch away from him.

85+

86+ Items oblivious to TouchRegistry will lose their touch points without warning, just like in plain Qt.
