Detailed Description

Used to select a range of values by sliding two handles along a track.

\qmltype RangeSlider
\inherits Control

! \instantiates QQuickRangeSlider \inqmlmodule QtQuick.Controls

Since

5.7

RangeSlider is used to select a range specified by two values, by sliding each handle along a track.

In the example below, custom \l from and \l to values are set, and the initial positions of the \l first and \l 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 \l {first.position} and \l {second.position} properties are expressed as fractions of the control's size, in the range {0.0 - 1.0}. The \l {first.visualPosition} and \l {second.visualPosition} properties are the same, except that they are reversed in a \l {Right-to-left User Interfaces}{right-to-left} application. The visualPosition is useful for positioning the handles when styling RangeSlider. In the example above, \l {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 \l Slider.
