ContextHub provides several sample UI modules that you can use in your solutions. The following information is provided:

  • The main features of the UI module.
  • Where to find the source code so that you can open it for learning purposes.
  • How to configure the UI module.

For information about adding UI modules to ContextHub, see Adding a UI Module. For information about developing UI modules, see Creating ContextHub UI Module Types.

contexthub.base UI Module Type

The contexthub.base UI module type is the base type for all other UI module types. As such it provides generic features for rendering store data.

The following features are available:

  • Title and icon: Specify a title for the UI module and an icon. The icon can be referenced using a URL or from the Coral UI icon library.
  • Store data: Identify one or more stores from which to retrieve data.
  • Content: Specify the content that appears in the UI module as it appears in the ContextHub toolbar.
  • Popover content: Specify the content that appears in a popover when the UI module is clicked or tapped.
  • Fullscreen mode: Control whether fullscreen mode is allowed.

The source code is located at /libs/granite/contexthub/code/ui/container/js/ContextHub.UI.BaseModuleRenderer.js.

Configuration

Configure the contexthub.base UI module using a Javascript object in JSON format. Include any of the following properties to configure the UI module features:

  • image: A URL to an image to display as the icon.
  • icon: The name of a Coral UI icon class. If you specify a value for both the icon and image properties, the image is used.
  • title: A title for the UI module. The title appears when the pointer is paused over the UI module icon.
  • fullscreen: A boolean value that indicates whether the UI module supports fullscreen mode. Use true to support fullscreen and false to prevent fullscreen mode.
  • template: A Handlebars template that specifies the content to render in the ContextHub toolbar. Use at most two <p> tags. 
  • storeMapping: A key/store mapping. Use the key in Handlebar templates to access the associated ContextHub store data. 
  • list: An array of items to display as a list in a popover when the UI module is clicked. If you include this item, do not include popoverTemplate. The value is an array of objects with the following keys:
    • title: The text to display for this item
    • image: (Optional) A URL to an image that should be displayed on the left
    • icon: (Optional) A CUI icon class that should be displayed on the left; ignored if an image is specified
    • selected: (Optional) A boolean value that specifies whether this item should be displayed as selected (true=selected). By default, selected items appear using a bold font. Use a listType property to configure other appearances (see below).
  • listType: The style to use for popover list items. Use one of the following values: 
    • checkmark
    • checkbox
    • radio
  • popoverTemplate: A Handlebars template that specifies the content to render in the popover when the UI module is clicked. If you include this item, do not include the list item.

Example

The following example configures a contexthub.base UI module to display information from a contexthub.emulators store. The template item demonstrates how to obtain data from the store by using the key that the storeMapping item establishes.

{
   "icon": "coral-Icon--move",
    "title": "Screen Resolution",
    "storeMapping": {
      "emulator": "emulators"
    },
    "template": "<p>{{{ i18n \"Resolution\"}}}</p><p>{{{emulator.currentDevice.width}}} x {{{emulator.currentDevice.height}}}</p>"
}
