Class: Themes

WebComponents. Themes

This is a custom HtmlElement (Web Component). The tag name is the following:

<cq-themes>

This web component displays available themes in a menu. It also allows for custom themes to be removed. The menu updates automatically with new themes that are created from the theme dialog.

Built in themes are merely the names of classes that will be added to the top element of the UIContext when selected.

Attributes

This component observes the following attributes and will change behavior if these attributes are modified:

attribute description
theme Name of last theme selected. Note the current theme's attributes may be changed after setting the theme.

Emitters

A custom event will be emitted by the component when a theme is selected or removed. See CIQ.UI.BaseComponent#emitCustomEvent for details on how to listen for this event. The details of the event contain the following:

property value
emitter this component
cause "useraction"
effect "select", "remove"
action "click"
value theme name

This component comes with a default markup which is used when the component tag contains no other markup when it is added to the DOM. The default markup provided has accessibility features.

Methods

addClaim()

emitCustomEvent(params)

Emits a custom event from the webcomponent. The event type of the emitted event is determined by the particular user action taken. Up to two events are emitted when this function is executed. The first is an event with the type of action performed, if there is one. For example, events which are spawned without user action will not emit this first event. The second event will have a type derived from the component name. For example, the cq-study-legend component will emit a "StudyLegend" type event. The payload of the event will contain a detail section specifying the component which emitted the event as well as the effect - which more clearly defines the type of action causing the emittance. The detail section may also include custom fields further categorizing the event and providing additional information. These details are documented within the web component's documentation.

Parameters:
Name Type Description
params object
Properties
Name Type Argument Default Description
cause string <optional>

The cause of the event. e.g., useraction, timeout, alert. Defaults to "useraction" if not set and action parameter is set.

Unless loop is set to true, then focus is applied to first element.
