Slider

Use a Slider widget to select from a range of values by moving a slider indicator horizontally. You can display minimum and maximum values, and update the displayed value when you drag the indicator along the slider.

To learn how to use this widget programmatically, refer Quantum Visualizer Widget guide.

Note: The Slider widget is not supported in SPA platforms.

Important Considerations

The following are important considerations for a Slider widget.

Look Properties

Look properties define the appearance of the widget. The following are the major properties you can set:

For descriptions of the properties available on the Look tab of the Properties pane, see Look.

Skin Properties

Skin properties define a skin for the widget, including background color, borders, and shadows. If the widget includes text, you can also specify the text font.

For a Slider widget, you can apply a skin and its associated properties for the following states:

Skin Definition
Left The skin applied to the background of the slider on left side of the thumb image.
Right The skin applied to the background of the slider on right side of the thumb image.
Min Label The skin applied to the min property of the slider.
Max Label The skin applied to the max property of the slider.

For more information about applying skins, see Understanding Skins and Themes.

Slider Properties

Slider properties specify properties that are available on any platform supported by Quantum Visualizer, and assign platform-specific properties.

Note: In this section, the properties that can be forked are identified by an icon located to the left of the property. For more information, see Fork a Widget Property.

Min Value

Specifies the minimum value that you can select.

Default: 0

Max Value

Specifies the maximum value that you can select.

Default: 100

Step

Specifies the increment by which the slider value is increased or decreased between the minimum and maximum values.

Default: 1

You can specify a value between the difference of the maximum and minimum values of the slider; for example, if the minimum value is 40 and the maximum value is 45, the step value can be between 1 and 5.

Selected Value

Specifies the value that is displayed as the selected value.

Default: 40

If you do not specify a selected value, the value displayed is the minimum value plus half the difference between the minimum and the maximum value. For example, if the minimum value is 0 and the maximum value is 100, the value displayed is 50.

If you specify a selected value that is less than the minimum value, the selected value uses the minimum value. If you specify a selected value that is greater than the maximum value, the selected value uses the maximum value.
