Module: Toolbar

An extension can register a Toolbar Module by defining a getToolbarModule method. This module is commonly used to define:

• Module: Toolbar
  • Example Toolbar Module
  • Button Definitions
  • Nested Toolbar Menus
  • Custom Components

Example toolbar button using the Dialog Service to show CINE controls.

Example Toolbar Module

The Toolbar Module should return an array of definitions and a defaultContext. There are currently a few different variations of definitions, each one is detailed further down.

export default {
  id: 'example-toolbar-module',

  /**
   * @param {object} params
   * @param {ServicesManager} params.servicesManager
   * @param {CommandsManager} params.commandsManager
   */
  getToolbarModule({ servicesManager, commandsManager }) {
    return {
      definitions: [
        /* Array of definitions */
      ],
      defaultContext: ['ROUTE:VIEWER'],
    };
  },
};

Button Definitions

The simplest definition has the following properties:

{
  id: 'StackScroll',
  label: 'Stack Scroll',
  icon: 'bars',
  type: 'setToolActive',
  commandName: 'setToolActive',
  commandOptions: { toolName: 'StackScroll' },
},

property	description	values
id	Unique string identifier for the definition	*
label	User/display friendly to show in UI	*
icon	A string name for an icon supported by the consuming application.	*
type	Used to determine the button's component and behavior	"setToolActive", "command"
commandName	(optional) The command to run when the button is used.	Any command registered by a CommandModule
commandOptions	(optional) Options to pass the target commandName	*
context	(optional) Overrides module's defaultContext	Array of string context names

Where a button with a type of setToolActive has an "active" styling applied when clicked; removing the active styling from all other buttons.

Nested Toolbar Menus

You can indicate that buttons should be grouped and nested in a submenu by including buttons property in a definition:

{
  id: 'More',
  label: 'More',
  icon: 'ellipse-circle',
  buttons: [
    {
      id: 'cstInvert',
      label: 'Invert',
      icon: 'circle',
      type: 'command',
      commandName: 'invertViewport',
    },
  ],
},

Custom Components

The Toolbar Modules supports rendering custom components in place of the application's default. In place of the type, commandName, and commandOptions properties, we instead specify a CustomComponent.

{
  id: 'Custom',
  label: 'Custom',
  icon: 'custom-icon',
  CustomComponent: CustomToolbarComponent,
}

The CustomComponent components will receive the following props:

<CustomComponent
  parentContext="{parentContext}"
  toolbarClickCallback="{_handleToolbarButtonClick.bind(this)}"
  button="{button}"
  key="{button.id}"
  activeButtons="{activeButtonsIds}"
  isActive="{isActive}"
/>

Property	Type	Description
activeButtons	string[]	list of active buttons
button	object	its own definition object
key	string	React key prop
isActive	boolean	If current button is active
parentContext	?	The parent component's context?
toolbarClickCallback	func	Callback method for clicks
