Detailed Description

Slider is used to select a value by sliding a handle along a track.

In the example below, custom from, value, and to values are set:

Slider { from: 1 value: 25 to: 100 }

The position property is expressed as a fraction of the control's size, in the range 0.0 - 1.0. The visualPosition property is the same, except that it is reversed in a right-to-left application. The visualPosition is useful for positioning the handle when styling Slider. In the example above, visualPosition will be 0.24 in a left-to-right application, and 0.76 in a right-to-left application.

For a slider that allows the user to select a range by providing two handles, see RangeSlider.

Property Documentation

This property holds the starting value for the range. The default value is 0.0.

See also to and value.

horizontal : bool [read-only, since QtQuick.Controls 2.3 (Qt 5.10)]

This property holds whether the slider is horizontal.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also orientation.

implicitHandleHeight : real [read-only, since QtQuick.Controls 2.5 (Qt 5.12)]

implicitHandleWidth : real [read-only, since QtQuick.Controls 2.5 (Qt 5.12)]

live : bool [since QtQuick.Controls 2.2 (Qt 5.9)]

This property holds whether the slider provides live updates for the value property while the handle is dragged.

The default value is true.

This property was introduced in QtQuick.Controls 2.2 (Qt 5.9).

See also value and valueAt().

orientation : enumeration

This property holds the orientation.

Possible values:

See also horizontal and vertical.

position : real [read-only]

This property holds the logical position of the handle.

The position is expressed as a fraction of the control's size, in the range 0.0 - 1.0. For visualizing a slider, the right-to-left aware visualPosition should be used instead.

See also value, visualPosition, and valueAt().

This property holds whether the slider is pressed by either touch, mouse, or keys.

This property holds the snap mode.

The snap mode determines how the slider handle behaves with regards to the stepSize.

Possible values:

In the following table, the various modes are illustrated with animations. The movement of the mouse cursor and the stepSize (0.2) are identical in each animation.

Value	Example
Slider.NoSnap
Slider.SnapAlways
Slider.SnapOnRelease

See also stepSize.

This property holds the end value for the range. The default value is 1.0.

See also from and value.

touchDragThreshold : real [since QtQuick.Controls 2.5 (Qt 5.12)]

This property holds the threshold (in logical pixels) at which a touch drag event will be initiated. The mouse drag threshold won't be affected. The default value is Application.styleHints.startDragDistance.

This property was introduced in QtQuick.Controls 2.5 (Qt 5.12).

See also QStyleHints.

This property holds the value in the range from - to. The default value is 0.0.

See also position.

vertical : bool [read-only, since QtQuick.Controls 2.3 (Qt 5.10)]

This property holds whether the slider is vertical.

This property was introduced in QtQuick.Controls 2.3 (Qt 5.10).

See also orientation.

visualPosition : real [read-only]

This property holds the visual position of the handle.

The position is expressed as a fraction of the control's size, in the range 0.0 - 1.0. When the control is mirrored, the value is equal to 1.0 - position. This makes the value suitable for visualizing the slider, taking right-to-left support into account.

See also position.

Signal Documentation

[since QtQuick.Controls 2.2 (Qt 5.9)] moved()

This signal is emitted when the slider has been interactively moved by the user by either touch, mouse, wheel, or keys.

Note: The corresponding handler is onMoved.

This signal was introduced in QtQuick.Controls 2.2 (Qt 5.9).

Method Documentation

[since QtQuick.Controls 2.1 (Qt 5.8)] real valueAt(real position)

Returns the value for the given position.

This method was introduced in QtQuick.Controls 2.1 (Qt 5.8).

See also value and position.
