Class Image

Adds the event action that can be performed on the widget.

Parameters

Return

Widget — The Object, for chaining.

Sets the alternative text of the image for accessibility. Required.

Parameters

Return

Image — This object, for chaining.

Sets an authorization action that opens a URL to the authorization flow when the object is clicked. This opens the URL in a new window. When the user finishes the authorization flow and returns to the application, the add-on reloads.

A UI object can only have one of setOpenLink(openLink), setOnClickAction(action), setOnClickOpenLinkAction(action), setAuthorizationAction(action), or setComposeAction(action, composedEmailType) set.

// ...

const action = CardService.newAuthorizationAction().setAuthorizationUrl('url');
CardService.newTextButton().setText('Authorize').setAuthorizationAction(action);

Parameters

Return

Image — This object, for chaining.

Sets an action that composes a draft email when the object is clicked. A UI object can only have one of setOpenLink(openLink), setOnClickAction(action), setOnClickOpenLinkAction(action), setAuthorizationAction(action), or setComposeAction(action, composedEmailType) set.

The Action parameter must specify a callback function that returns a ComposeActionResponse object configured using ComposeActionResponseBuilder.setGmailDraft(draft).

// ...

const action = CardService.newAction().setFunctionName('composeEmailCallback');
CardService.newTextButton()
    .setText('Compose Email')
    .setComposeAction(action, CardService.ComposedEmailType.REPLY_AS_DRAFT);

// ...

function composeEmailCallback(e) {
  const thread = GmailApp.getThreadById(e.threadId);
  const draft = thread.createDraftReply('This is a reply');
  return CardService.newComposeActionResponseBuilder()
      .setGmailDraft(draft)
      .build();
}

Parameters

Return

Image — This object, for chaining.

Sets the unique ID assigned that's used to identify the widget to be mutated. Widget mutation is only supported in Add-Ons.

Parameters

Return

Widget — This object, for chaining.

Sets the image to use by providing its URL or data string. Required.

The provided URL can either be a publicly accessible URL or a base64 encoded image string. To obtain the latter, you can use the following code to create an encoded image string from an image in your Google Drive, then store that string for later use with setImageUrl(url). This method prevents the need for your add-on to access a publicly available image URL:

// The following assumes you have the image to use in Google Drive and have its
// ID.
const imageBytes = DriveApp.getFileById('123abc').getBlob().getBytes();
const encodedImageURL =
    `data:image/jpeg;base64,${Utilities.base64Encode(imageBytes)}`;

// You can store encodeImageURL and use it as a parameter to
// Image.setImageUrl(url).

Parameters

Return

Image — This object, for chaining.

Sets an action that executes when the object is clicked. A UI object can only have one of setOpenLink(openLink), setOnClickAction(action), setOnClickOpenLinkAction(action), setAuthorizationAction(action), or setComposeAction(action, composedEmailType) set.

The Action parameter must specify a callback function that returns a ActionResponse object.

// ...

const action = CardService.newAction().setFunctionName('notificationCallback');
CardService.newTextButton()
    .setText('Create notification')
    .setOnClickAction(action);

// ...

function notificationCallback() {
  return CardService.newActionResponseBuilder()
      .setNotification(
          CardService.newNotification().setText('Some info to display to user'),
          )
      .build();
}

Parameters

Return

Image — This object, for chaining.

Sets an action that opens a URL in a tab when the object is clicked. Use this function when the URL needs to be built or when you need to take other actions in addition to creating the OpenLink object. A UI object can only have one of setOpenLink(openLink), setOnClickAction(action), setOnClickOpenLinkAction(action), setAuthorizationAction(action), or setComposeAction(action, composedEmailType) set.

The Action parameter must specify a callback function that returns a ActionResponse object configured using ActionResponseBuilder.setOpenLink(openLink).

// ...

const action = CardService.newAction().setFunctionName('openLinkCallback');
CardService.newTextButton()
    .setText('Open Link')
    .setOnClickOpenLinkAction(action);

// ...

function openLinkCallback() {
  return CardService.newActionResponseBuilder()
      .setOpenLink(CardService.newOpenLink().setUrl('https://www.google.com'))
      .build();
}

Parameters

Return

Image — This object, for chaining.

Sets a URL to be opened when the object is clicked. Use this function when the URL is already known and only needs to be opened. A UI object can only have one of setOpenLink(openLink), setOnClickAction(action), setOnClickOpenLinkAction(action), setAuthorizationAction(action), or setComposeAction(action, composedEmailType) set.
