TooltipHiddenEvent

Information about the event.

Object structure:
Name Type Description
element

HTMLElement | jQuery

The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.
component

Bullet

The UI component's instance.
Default Value: null
Cannot be used in themes.

onTooltipShown

A function that is executed when a tooltip appears.

Selector: @tooltip-shown
Type:

Function

Function parameters:
e:

TooltipShownEvent

Information about the event.

Object structure:
Name Type Description
element

HTMLElement | jQuery

The UI component's container. It is an HTML Element or a jQuery Element when you use jQuery.
component

Bullet

The UI component's instance.
Default Value: null
Cannot be used in themes.

pathModified

Notifies the UI component that it is embedded into an HTML page that uses a tag modifying the path.

Selector: path-modified
Type:

Boolean

Default Value: false
Cannot be used in themes.

If you place the UI component on a page that uses a tag modifying the path (<base>, <iframe>, etc.), some of the UI component elements may get mixed up or disappear. To solve this problem, set the pathModified property to true.

See Also

rtlEnabled

Switches the UI component to a right-to-left representation.

Selector: rtl-enabled
Type:

Boolean

Default Value: false
Cannot be used in themes.

When this property is set to true, the UI component 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
});
NOTE
In a right-to-left representation, SVG elements have the direction attribute with the rtl value. This might cause problems when rendering left-to-right texts. Use this property if you have only right-to-left texts.

showTarget

Specifies whether or not to show the target line.

Selector: show-target
Type:

Boolean

Default Value: true

See Also

showZeroLevel

Specifies whether or not to show the line indicating zero on the invisible scale.

Selector: show-zero-level
Type:

Boolean

Default Value: true

See Also

size

Specifies the UI component's size in pixels.

Selector: DxSize
Type: viz/core/base_widget:BaseWidgetSize
Default Value: {height: 30, width: 300}

You can specify a custom width and height for the component:

Fixed Relative
Assign values to the size object's height and width properties or specify a container for the component. Specify a container for the component. The component occupies the container area on initialization. If a container's size changes, the component's size does not change. If you want to update the size, call the render method.
NOTE

  • The size object has priority over the container.

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

jQuery
index.js
$(function() {
    $("#bulletContainer").dxBullet({
        // ...
        size: {
            height: 300,

});
#bullet {

    },
    // ...

</script>

<style>
#bullet {
    width: 85%;
    height: 70%;
}
</style>
React
App.js
styles.css
import React from 'react';

import Bullet from 'devextreme-react/bullet';

class App extends React.Component {
    render() {
        return (
            <Bullet ...
                id="bullet">
            </Bullet>
        );
    }
}
export default App;
#bullet {
    width: 85%;
    height: 70%;
}

startScaleValue

Specifies a start value for the invisible scale.

Selector: start-scale-value
Type:

Number

Default Value: 0
Cannot be used in themes.

The main, target and zero values of the Bullet UI component 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 properties.

Specify the same start and end scale values for several bullets when you display them in a column so that they can be comparable visually.

target

Specifies the value indicated by the target line.

Type:

Number

Default Value: 0
Cannot be used in themes.

See Also

targetColor

Specifies a color for both the target and zero level lines.

Selector: target-color
Type:

String

Default Value: '#666666'

This property supports the following colors:

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

targetWidth

Specifies the width of the target line.

Selector: target-width
Type:

Number

Default Value: 4

theme

Sets the name of the theme the UI component uses.

Type:

Theme

Default Value: 'generic.light'

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

tooltip

Configures the tooltip.

Selector: DxTooltip
Type: viz/sparklines/base_sparkline:BaseSparklineTooltip

A tooltip is a miniature rectangle displaying UI component data. The tooltip appears when the end-user hovers the cursor over the UI component. 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 UI component's container. If you plan to use the tooltip, make sure there is enough space around your UI component to display it. For example, you can apply a margin to the UI component's container to reserve the area around the UI component for the tooltip.

value

Specifies the primary value indicated by the bullet bar.

Type:

Number

Default Value: 0
Cannot be used in themes.
