RangeSlider QML Type▲
-
Import Statement: import QtQuick.Controls
-
Inherits: Control
-
Group: RangeSlider is part of qtquickcontrols-input, qtquickcontrols-focusscopes
Detailed Description▲
RangeSlider is used to select a range specified by two values, by sliding each handle along a track.
In the example below, custom from and to values are set, and the initial positions of the first and second handles are set:
RangeSlider {
from: 1
to: 100
first.value: 25
second.value: 75
}In order to perform an action when the value for a particular handle changes, use the following syntax:
first.onMoved: console.log("first.value changed to " + first.value)The first.position and second.position properties are expressed as fractions of the control's size, in the range 0.0 - 1.0. The first.visualPosition and second.visualPosition properties are the same, except that they are reversed in a right-to-left application. The visualPosition is useful for positioning the handles when styling RangeSlider. In the example above, first.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 single value, see Slider.

Property |
Description |
|---|---|
|
value |
This property holds the value of the first handle in the range from - to. If from is greater than to, the value of the first handle must be greater than the second, and vice versa. The default value is 0.0. |
|
handle |
This property holds the first handle item. |
|
visualPosition |
This property holds the visual position of the first 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. |
|
position |
This property holds the logical position of the first 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. |
|
pressed |
This property holds whether the first handle is pressed by either touch, mouse, or keys. |
|
hovered |
This property holds whether the first handle is hovered. This property was introduced in QtQuick.Controls 2.1. |
|
implicitHandleWidth |
This property holds the implicit width of the first handle. This property was introduced in QtQuick.Controls 2.5. |
|
implicitHandleHeight |
This property holds the implicit height of the first handle. This property was introduced in QtQuick.Controls 2.5. |

[read-only, since QtQuick.Controls 2.3 (Qt 5.10)] horizontal : bool▲
This property holds whether the slider is horizontal.

[since QtQuick.Controls 2.2 (Qt 5.9)] live : bool▲
This property holds whether the slider provides live updates for the first.value and second.value properties while the respective handles are dragged.
The default value is true.
This property was introduced in QtQuick.Controls 2.2 (Qt 5.9).

orientation : enumeration▲
This property holds the orientation.
Possible values:

Property |
Description |
|---|---|
|
value |
This property holds the value of the second handle in the range from - to. If from is greater than to, the value of the first handle must be greater than the second, and vice versa. The default value is 0.0. |
|
handle |
This property holds the second handle item. |
|
visualPosition |
This property holds the visual position of the second 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. |
|
position |
This property holds the logical position of the second 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. |
|
pressed |
This property holds whether the second handle is pressed by either touch, mouse, or keys. |
|
hovered |
This property holds whether the second handle is hovered. This property was introduced in QtQuick.Controls 2.1. |
|
implicitHandleWidth |
This property holds the implicit width of the second handle. This property was introduced in QtQuick.Controls 2.5. |
|
implicitHandleHeight |
This property holds the implicit height of the second handle. This property was introduced in QtQuick.Controls 2.5. |

snapMode : enumeration▲
This property holds the snap mode.
The snap mode determines how the slider handles behave with regards to the stepSize.
Possible values:
|
Constant |
Description |
|---|---|
|
RangeSlider.NoSnap |
The slider does not snap (default). |
|
RangeSlider.SnapAlways |
The slider snaps while the handle is dragged. |
|
RangeSlider.SnapOnRelease |
The slider does not snap while being dragged, but only after the handle is released. |
For visual explanations of the various modes, see the snapMode documentation of Slider.

void first.increase()▲
Increases the value of the handle by stepSize, or 0.1 if stepSize is not defined.

See also first
void second.decrease()▲
Decreases the value of the handle by stepSize, or 0.1 if stepSize is not defined.

void second.increase()▲
Increases the value of the handle by stepSize, or 0.1 if stepSize is not defined.

See also second
void setValues(real firstValue, real secondValue)▲
Sets first.value and second.value with the given arguments.
If to is larger than from and firstValue is larger than secondValue, firstValue will be clamped to secondValue.
If from is larger than to and secondValue is larger than firstValue, secondValue will be clamped to firstValue.
This function may be necessary to set the first and second values after the control has been completed, as there is a circular dependency between firstValue and secondValue which can cause assigned values to be clamped to each other.

[since QtQuick.Controls 2.5 (Qt 5.12)] real valueAt(real position)▲
Returns the value for the given position.
This method was introduced in QtQuick.Controls 2.5 (Qt 5.12).
