Constructor & Destructor Documentation

◆ QQuickFlickable() [1/2]

QQuickFlickable::QQuickFlickable ( QQuickItem * parent = nullptr )

\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 \instantiates 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.

◆ boundsBehavior()

QQuickFlickable::BoundsBehavior QQuickFlickable::boundsBehavior ( ) const

\qmlproperty enumeration QtQuick::Flickable::boundsBehavior This property holds whether the surface may be dragged beyond the Flickable's boundaries, or overshoot the Flickable's boundaries when flicked.

When the \l boundsMovement is Flickable.FollowBoundsBehavior, a value other than Flickable.StopAtBounds will give a feeling that the edges of the view are soft, rather than a hard physical boundary.

The boundsBehavior can be one of:

\list

Flickable.StopAtBounds - the contents can not be dragged beyond the boundary of the flickable, and flicks will not overshoot.
Flickable.DragOverBounds - the contents can be dragged beyond the boundary of the Flickable, but flicks will not overshoot.
Flickable.OvershootBounds - the contents can overshoot the boundary when flicked, but the content cannot be dragged beyond the boundary of the flickable. (since {QtQuick 2.5})
Flickable.DragAndOvershootBounds (default) - the contents can be dragged beyond the boundary of the Flickable, and can overshoot the boundary when flicked. \endlist

◆ boundsMovement()

QQuickFlickable::BoundsMovement QQuickFlickable::boundsMovement ( ) const

\qmlproperty enumeration QtQuick::Flickable::boundsMovement

Since: 5.10

This property holds whether the flickable will give a feeling that the edges of the view are soft, rather than a hard physical boundary.

The boundsMovement can be one of:

\list

Flickable.StopAtBounds - this allows implementing custom edge effects where the contents do not follow drags or flicks beyond the bounds of the flickable. The values of \l horizontalOvershoot and \l verticalOvershoot can be utilized to implement custom edge effects.
Flickable.FollowBoundsBehavior (default) - whether the contents follow drags or flicks beyond the bounds of the flickable is determined by \l boundsBehavior. \endlist

The following example keeps the contents within bounds and instead applies a flip effect when flicked over horizontal bounds:

Flickable {
    id: flickable
    boundsMovement: Flickable.StopAtBounds
    boundsBehavior: Flickable.DragAndOvershootBounds
    transform: Rotation {
        axis { x: 0; y: 1; z: 0 }
        origin.x: flickable.width / 2
        origin.y: flickable.height / 2
        angle: Math.min(30, Math.max(-30, flickable.horizontalOvershoot))
    }
}

The following example keeps the contents within bounds and instead applies an opacity effect when dragged over vertical bounds:

Flickable {
    boundsMovement: Flickable.StopAtBounds
    boundsBehavior: Flickable.DragOverBounds
    opacity: Math.max(0.5, 1.0 - Math.abs(verticalOvershoot) / height)
}

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:

Flickable {
    id: myFlickable

        var component = Qt.createComponent(file)

◆ contentWidth()

qreal QQuickFlickable::contentWidth ( ) const

\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:

import QtQuick
 
Flickable {
    width: 200; height: 200
    contentWidth: image.width; contentHeight: image.height
 
    Image { id: image; source: "bigImage.png" }
}

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:

contentWidth: contentItem.childrenRect.width; contentHeight: contentItem.childrenRect.height

◆ contentX()

qreal QQuickFlickable::contentX ( ) const

\qmlproperty real QtQuick::Flickable::contentX \qmlproperty real QtQuick::Flickable::contentY

These properties hold the surface coordinate currently at the top-left corner of the Flickable. For example, if you flick an image up 100 pixels, contentY will increase by 100.

Note: If you flick back to the origin (the top-left corner), after the rebound animation, 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}.

Whether the values are reported for dragging and/or flicking is determined by \l boundsBehavior. The overshoot distance is reported even when \l boundsMovement is Flickable.StopAtBounds.

The reported velocity is smoothed to avoid erratic output.

Note that for views with a large content size (more than 10 times the view size), the velocity of the flick may exceed the velocity of the touch in the case of multiple quick consecutive flicks. This allows the user to flick faster through large content.

This property describes whether the user can interact with the Flickable. A user cannot drag or flick a Flickable that is not interactive.

By default, this property is true.

This property is useful for temporarily disabling flicking. This allows special interaction with Flickable's children; for example, you might want to freeze a flickable map while scrolling through a pop-up dialog that is a child of the Flickable.

This property holds the time to delay (ms) delivering a press to children of the Flickable. This can be useful where reacting to a press before a flicking action has undesirable effects.

If the flickable is dragged/flicked before the delay times out the press event will not be delivered. If the button is released within the timeout, both the press and release will be delivered.

Note that for nested Flickables with pressDelay set, the pressDelay of outer Flickables is overridden by the innermost Flickable. If the drag exceeds the platform drag threshold, the press event will be delivered regardless of this property.

This holds the transition to be applied to the content view when it snaps back to the bounds of the flickable. The transition is triggered when the view is flicked or dragged past the edge of the content area, or when returnToBounds() is called.

\qml import QtQuick 2.0

Flickable { width: 150; height: 150 contentWidth: 300; contentHeight: 300

rebound: Transition { NumberAnimation { properties: "x,y" duration: 1000 easing.type: Easing.OutBounce } }

Rectangle { width: 300; height: 300 gradient: Gradient { GradientStop { position: 0.0; color: "lightsteelblue" } GradientStop { position: 1.0; color: "blue" } } } } \endqml

When the above view is flicked beyond its bounds, it will return to its bounds using the transition specified:

If this property is not set, a default animation is applied.
