\qmlsignal QtQuick::Flickable::dragStarted()
This signal is emitted when the view starts to be dragged due to user interaction.
\qmlsignal QtQuick::Flickable::dragEnded()
This signal is emitted when the user stops dragging the view.
If the velocity of the drag is sufficient at the time the touch/mouse button is released then a flick will start.
\qmltype Flickable \nativetype QQuickFlickable \inqmlmodule QtQuick
Provides a surface that can be "flicked". \inherits Item
The Flickable item places its children on a surface that can be dragged and flicked, causing the view onto the child items to scroll. This behavior forms the basis of Items that are designed to show large numbers of child items, such as \l ListView and \l GridView.
In traditional user interfaces, views can be scrolled using standard controls, such as scroll bars and arrow buttons. In some situations, it is also possible to drag the view directly by pressing and holding a mouse button while moving the cursor. In touch-based user interfaces, this dragging action is often complemented with a flicking action, where scrolling continues after the user has stopped touching the view.
Flickable does not automatically clip its contents. If it is not used as a full-screen item, you should consider setting the \l{Item::}{clip} property to true.

\qmlproperty flags QtQuick::Flickable::acceptedButtons
The mouse buttons that can be used to scroll this Flickable by dragging.
By default, this property is set to \l {QtQuick::MouseEvent::button} {Qt.LeftButton}, which provides the same behavior as in previous Qt versions; but in most user interfaces, this behavior is unexpected. Users expect to flick only on a touchscreen, and to use the mouse wheel, touchpad gestures or a scroll bar with mouse or touchpad. Set it to Qt.NoButton
to disable dragging.
It can be set to an OR combination of mouse buttons, and will ignore events from other buttons.

QQuickItem * QQuickFlickable::contentItem | ( | ) | const |
\qmlproperty Item QtQuick::Flickable::contentItem
The internal item that contains the Items to be moved in the Flickable.
Items declared as children of a Flickable are automatically parented to the Flickable's contentItem.
Items created dynamically need to be explicitly parented to the contentItem:

\qmlproperty real QtQuick::Flickable::contentWidth \qmlproperty real QtQuick::Flickable::contentHeight
The dimensions of the content (the surface controlled by Flickable). This should typically be set to the combined size of the items placed in the Flickable.
The following snippet shows how these properties are used to display an image that is larger than the Flickable item itself:
In some cases, the content dimensions can be automatically set based on the \l {Item::childrenRect.width}{childrenRect.width} and \l {Item::childrenRect.height}{childrenRect.height} properties of the \l contentItem. For example, the previous snippet could be rewritten with:

will increase by 100.
contentX
will settle to the same value as originX
, and contentY
to originY
. These are usually (0,0), however ListView and GridView may have an arbitrary origin due to delegate size variation, or item insertion/removal outside the visible region. So if you want to implement something like a vertical scrollbar, one way is to use {y:
(contentY - originY) * (height / contentHeight)} for the position; another way is to use the normalized values in \l {QtQuick::Flickable::visibleArea}{visibleArea}.Definition at line 799 of file qquickflickable.cpp.
