When this option is set to true, the widget text flows from right to left, and the layout of elements is reversed. To switch the entire application/site to the right-to-left representation, assign true to the rtlEnabled field of the object passed to the DevExpress.config(config) method.

JavaScript

DevExpress.config({
    rtlEnabled: true
});

size

Specifies the widget's size in pixels.

Type:

Default Value: undefined

By default, the widget occupies the entire area of the container. If you need to set a particular size for the widget, different from the container's size, assign a height and width in pixels to height and width properties of the size object.

Using the size object, you can hide the widget. For this purpose, simply assign 0 to both the height and width of the widget.

NOTE

The size configuration object reserves space for the main widget elements, while displaying a tooltip may require extra space. To reserve the area around the widget for the tooltip, you can apply a margin to the widget's container.

startScaleValue

Specifies a start value for the invisible scale.

Type:

Default Value: 0

The main, target and zero values of the Bullet widget are contained within a range. This range is represented by an invisible scale. To specify the boundary values of this scale, set the startScaleValue and endScaleValue options.

To specify a color for the bullet bar, use the color option.

targetWidth

Specifies the width of the target line.

Type:

Default Value: 4

theme

Sets the name of the theme the widget uses.

Type:

String

Default Value: 'generic.light'

A theme is a widget configuration that gives the widget a distinctive appearance. Use can use one of the predefined themes or create a custom one. Changing the option values in the widget's configuration object overrides the theme's corresponding values.

The following themes were deprecated or renamed: 'desktop', 'desktop-dark', 'android', 'android-holo-light', *android5.light*, 'ios', 'win8', 'win8-white', 'win8.white', 'win8.black', 'win10.white', 'win10.black'. In new applications, use themes listed in the accepted values.

Use the VizTheme enum to specify this option when the widget is used as an ASP.NET MVC Control. This enum accepts the following values: GenericLight, GenericDark, GenericContrast, GenericCarmine, GenericDarkMoon, GenericSoftBlue, GenericDarkViolet, GenericGreenMist, IOS7Default, MaterialBlueLight, MaterialLimeLight, MaterialOrangeLight, MaterialPurpleLight, MaterialTealLight.

Type:

A tooltip is a miniature rectangle displaying widget data. The tooltip appears when the end-user hovers the cursor over the widget. You can enable/disable the tooltip, change its appearance and format its text using fields of the tooltip configuration object.

NOTE

The tooltip is displayed outside the widget's container. If you plan to use the tooltip, make sure there is enough space around your widget to display it. For example, you can apply a margin to the widget's container to reserve the area around the widget for the tooltip.
