Methods
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.

Property Documentation
handle : Item |
This property holds the handle item.
See also Customizing Slider.
This property holds the orientation.
Possible values:
| Constant | Description |
|---|---|
Qt.Horizontal | Horizontal (default) |
Qt.Vertical | Vertical |
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 the snap mode.
Possible values:
| Constant | Description |
|---|---|
Slider.NoSnap | The slider does not snap (default). |
Slider.SnapAlways | The slider snaps while the handle is dragged. |
Slider.SnapOnRelease | The slider does not snap while being dragged, but only after the handle is released. |
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 step size. The default value is 0.0.
See also snapMode, increase(), and decrease().
This property holds the value in the range from - to. The default value is 0.0.
See also position.
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.
