`addItem(gridItem)`

Adds a new grid item to the grid.

Parameters

Name	Type	Description
`gridItem`	`GridItem`	The grid item to add.

Return

Grid — This object, for chaining.

`setAuthorizationAction(action)`

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.

// ...

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

Parameters

Name	Type	Description
`action`	`AuthorizationAction`	The object that specifies the authorization action to take when this element is clicked.

Return

Grid — This object, for chaining.

`setBorderStyle(borderStyle)`

Sets the border style applied to each grid item. Default is NO_BORDER.

Parameters

Name	Type	Description
`borderStyle`	`BorderStyle`	The border style to apply.

Return

Grid — This object, for chaining.

`setComposeAction(action, composedEmailType)`

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).

Note: This method doesn't set a compose action that is used to extend the compose UI. Rather, this method connects this UI element to an Action that composes draft messages in Apps Script that are opened in Gmail when the action completes.

// ...

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

// ...

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

Parameters

Name	Type	Description
`action`	`Action`	The object that specifies the compose action to take when this element is clicked.
`composedEmailType`	`ComposedEmailType`	An enum value that specifies whether the composed draft is a standalone or reply draft.

Return

`setNumColumns(numColumns)`
