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 }
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.

Property Documentation
first.handle : Item |
Property | Description |
---|---|
value | This property holds the value of the first handle in the range from - to .If to is greater than from, the value of the first handle must be greater than the second, and vice versa. Unlike position, value is not updated while the handle is dragged, but rather when it has been released. The default value is |
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 |
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 |
pressed | This property holds whether the first handle is pressed. |
hovered | This property holds whether the first handle is hovered. This property was introduced in QtQuick.Controls 2.1. |
See also first.increase() and first.decrease().
This property holds the starting value for the range. The default value is 0.0
.
See also to, first.value, and second.value.
This property holds the orientation.
Possible values:
Constant | Description |
---|---|
Qt.Horizontal | Horizontal (default) |
Qt.Vertical | Vertical |
second.handle : Item |
Property | Description |
---|---|
value | This property holds the value of the second handle in the range from - to .If to is greater than from, the value of the first handle must be greater than the second, and vice versa. Unlike position, value is not updated while the handle is dragged, but rather when it has been released. The default value is |
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 |
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 |
pressed | This property holds whether the second handle is pressed. |
hovered | This property holds whether the second handle is hovered. This property was introduced in QtQuick.Controls 2.1. |
See also second.increase() and second.decrease().
This property holds the snap mode.
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.
See also stepSize.
This property holds the step size. The default value is 0.0
.
See also snapMode, first.increase(), and first.decrease().
This property holds the end value for the range. The default value is 1.0
.
See also from, first.value, and second.value.
Method Documentation
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.
