These properties are true if the flickable view is positioned at the beginning, or end respectively.

These properties hold the margins around the content. This space is reserved in addition to the contentWidth and contentHeight.

This property holds whether the surface may be dragged beyond the Flickable's boundaries, or overshoot the Flickable's boundaries when flicked.

This enables the feeling that the edges of the view are soft, rather than a hard physical boundary.

The boundsBehavior can be one of:

• 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.DragAndOvershootBounds (default) - the contents can be dragged beyond the boundary of the Flickable, and can overshoot the boundary when flicked.

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 2.0

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 childrenRect.width and childrenRect.height properties of the contentItem. For example, the previous snippet could be rewritten with:

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

Though this assumes that the origin of the childrenRect is 0,0.

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:

Flickable {
    id: myFlickable
    function addItem(file) {
        var component = Qt.createComponent(file)
        component.createObject(myFlickable.contentItem);
    }
}

    Image { id: image; source: "bigImage.png" }
}

In some cases, the content dimensions can be automatically set based on the childrenRect.width and childrenRect.height properties of the contentItem. For example, the previous snippet could be rewritten with:

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

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 be 100.

These properties describe whether the view is currently moving horizontally, vertically or in either direction, due to the user dragging the view.

This property holds the rate at which a flick will decelerate.

The default value is platform dependent.

This property determines which directions the view can be flicked.

• Flickable.AutoFlickDirection (default) - allows flicking vertically if the contentHeight is not equal to the height of the Flickable. Allows flicking horizontally if the contentWidth is not equal to the width of the Flickable.
• Flickable.HorizontalFlick - allows flicking horizontally.
• Flickable.VerticalFlick - allows flicking vertically.
• Flickable.HorizontalAndVerticalFlick - allows flicking in both directions.

These properties describe whether the view is currently moving horizontally, vertically or in either direction, due to the user flicking the view.

These properties describe whether the view is currently moving horizontally, vertically or in either direction, due to the user flicking the view.

These properties describe whether the view is currently moving horizontally, vertically or in either direction, due to the user flicking the view.

The instantaneous velocity of movement along the x and y axes, in pixels/sec.

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.

These properties hold the margins around the content. This space is reserved in addition to the contentWidth and contentHeight.

This property holds the maximum velocity that the user can flick the view in pixels/second.

The default value is platform dependent.

These properties describe whether the view is currently moving horizontally, vertically or in either direction, due to the user either dragging or flicking the view.

These properties hold the origin of the content. This value always refers to the top-left position of the content regardless of layout direction.

This is 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.

This is 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.

This property sets the alignment of contentX and contentY to pixels (true) or subpixels (false).

Enable pixelAligned to optimize for still content or moving content with high constrast edges, such as one-pixel-wide lines, text or vector graphics. Disable pixelAligned when optimizing for animation quality.

The default is false.

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.

See also QStyleHints.

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.

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" }
        }
    }
}

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.

The instantaneous velocity of movement along the x and y axes, in pixels/sec.

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.

These properties describe the position and size of the currently viewed area. The size is defined as the percentage of the full view currently visible, scaled to 0.0 - 1.0. The page position is usually in the range 0.0 (beginning) to 1.0 minus size ratio (end), i.e. yPosition is in the range 0.0 to 1.0-heightRatio. However, it is possible for the contents to be dragged outside of the normal range, resulting in the page positions also being outside the normal range.

These properties are typically used to draw a scrollbar. For example:

Rectangle {
    width: 200; height: 200

    Flickable {
        id: flickable
        ...
    }

    Rectangle {
        id: scrollbar
        anchors.right: flickable.right
        y: flickable.visibleArea.yPosition * flickable.height
        width: 10
        height: flickable.visibleArea.heightRatio * flickable.height
        color: "black"
    }
}

This signal is emitted when the view stops moving due to a flick.

The corresponding handler is onFlickEnded.

This signal is emitted when the view is flicked. A flick starts from the point that the mouse or touch is released, while still in motion.

The corresponding handler is onFlickStarted.

This signal is emitted when the view stops moving due to user interaction. If a flick was generated, this signal will be emitted once the flick stops. If a flick was not generated, this signal will be emitted when the user stops dragging - i.e. a mouse or touch release.

The corresponding handler is onMovementEnded.

This signal is emitted when the view begins moving due to user interaction.

The corresponding handler is onMovementStarted.

Cancels the current flick animation.

Flicks the content with xVelocity horizontally and yVelocity vertically in pixels/sec.

Resizes the content to width x height about center.

This does not scale the contents of the Flickable - it only resizes the contentWidth and contentHeight.

Resizing the content may result in the content being positioned outside the bounds of the Flickable. Calling returnToBounds() will move the content back within legal bounds.

Ensures the content is within legal bounds.

This may be called to ensure that the content is within legal bounds after manually positioning the content.
