16+

17+/*

18+ * Some documentation on how this thing works:

19+ *

20+ * A flickable has two very important concepts that define the top and

21+ * height of the flickable area.

22+ * The top is returned in minYExtent()

23+ * The height is set using setContentHeight()

24+ * By changing those two values we can make the list grow up or down

25+ * as needed. e.g. if we are in the middle of the list

26+ * and something that is above the viewport grows, since we do not

27+ * want to change the viewport because of that we just adjust the

28+ * minYExtent so that the list grows up.

29+ *

30+ * The implementation on the list relies on the delegateModel doing

31+ * most of the instantiation work. You call createItem() when you

32+ * need to create an item asking for it async or not. If returns null

33+ * it means the item will be created async and the model will call the

34+ * itemCreated slot with the item.

35+ *

36+ * updatePolish is the central point of dispatch for the work of the

37+ * class. It is called by the scene graph just before drawing the class.

38+ * In it we:

39+ * * Make sure all items are positioned correctly

40+ * * Add/Remove items if needed

41+ * * Update the content height if it was dirty

42+ *

43+ * m_visibleItems contains all the items we have created at the moment.

44+ * Actually not all of them are visible since it includes the ones

45+ * in the cache area we create asynchronously to help performance.

46+ * The first item in m_visibleItems has the m_firstVisibleIndex in

47+ * the model. If you actually want to know what is the first

48+ * item in the viewport you have to find the first non culled element

49+ * in m_visibleItems

50+ *

51+ * All the items (except the header) are childs of m_clipItem which

52+ * is a child of the contentItem() of the flickable (The contentItem()

53+ * is what actually 'moves' in a a flickable). This way

54+ * we can implement the clipping needed so we can have the header

55+ * shown in the middle of the list over the items without the items

56+ * leaking under the header in case it is transparent.

57+ *

58+ * The first item of m_visibleItems is the one that defines the

59+ * positions of all the rest of items (see updatePolish()) and

60+ * this is why sometimes we move it even if it's not the item

61+ * that has triggered the function (i.e. in itemGeometryChanged())

62+ *

63+ * m_visibleItems is a list of ListItem. Each ListItem

64+ * will contain a item and potentially a sectionItem. The sectionItem

65+ * is only there when the list is using sectionDelegate+sectionProperty

66+ * and this is the first item of the section. Each ListItem is vertically

67+ * layouted with the sectionItem first and then the item.

68+ *

69+ * For sectioning we also have a section item alone (m_topSectionItem)

70+ * that is used for the cases we need to show the sticky section item at

71+ * the top of the view.

72+ *

73+ * Each delegate item has a context property called heightToClip that is

74+ * used to communicate to the delegate implementation in case it has to

75+ * clip itself because of overlapping with the top sticky section item.

76+ * This is an implementation decision since it has been agreed it

77+ * is easier to implement the clipping in QML with this info than to

78+ * do it at the C++ level.

79+ *

80+ * Note that minYExtent and height are not always totally accurate, since

81+ * we don't have the items created we can't guess their heights

82+ * so we can only guarantee the values are correct when the first/last

83+ * items of the list are visible, otherwise we just live with good enough

84+ * values that make the list scrollable

85+ *

86+ * There are a few things that are not really implemented or tested properly

87+ * which we don't use at the moment like changing the model, changing

88+ * the section delegate, having a section delegate that changes its size, etc.

89+ * The known missing features are marked with TODOs along the code.

30+ Note for users of this class

31+

32+ ListViewWithPageHeader already loads delegates async when appropiate so if

33+ your delegate uses a Loader you should not enable the asynchronous feature since

34+ that will need to introduce sizing problems

35+

36+ With the double async it may happen what while we are scrolling down

37+ we reach to a point where given the size of the just created delegate with loader not yet loaded (which will be very close to 0)

38+ we are already "at the end" of the list, but then a few milliseconds later the loader finishes loading and we could

39+ have kept scrolling. This is specially visible at the end of the list where you realize

40+ that scrolling ended a bit before the end of the list but the speed of the flicking was good

41+ to reach the end

42+

43+ By not having the second async we get a better sizing when the delegate is created and things work better
