Utilizza gli oggetti Azione per integrare un comportamento interattivo nei componenti aggiuntivi di Google Workspace.
Gli oggetti azione definiscono cosa succede quando un utente interagisce con un widget
(ad esempio un pulsante) nell'interfaccia utente del componente aggiuntivo.
Aggiungere un'azione a un widget
Per collegare un'azione a un widget, utilizza una funzione di gestione dei widget,
che definisce anche la condizione che attiva l'azione. Quando viene attivata, l'azione esegue una funzione di callback designata.
Alla funzione di callback viene passato un oggetto evento
che contiene informazioni sulle interazioni lato client dell'utente. Devi
implementare la funzione di callback e farle restituire un oggetto di risposta specifico.
Esempio: visualizzare una nuova scheda quando viene fatto clic su un pulsante
Se vuoi aggiungere un pulsante al tuo componente aggiuntivo che crea e visualizza una nuova scheda
quando viene selezionato, segui questi passaggi:
Per impostare un'azione di creazione di una scheda, aggiungi la funzione di gestione del widget pulsante
setOnClickAction(action).
Crea una funzione di callback Apps Script da eseguire e specificala come
(action)
all'interno della funzione di gestione dei widget. In questo caso, la funzione di callback
deve creare la scheda che vuoi e restituire un oggetto ActionResponse. L'oggetto risposta indica al componente aggiuntivo di visualizzare la scheda creata dalla funzione di callback.
Il seguente esempio mostra la creazione di un widget pulsante. L'azione richiede
l'ambito drive.file per il file corrente per conto del componente aggiuntivo.

Interazioni di accesso ai file per le API REST
I componenti aggiuntivi di Google Workspace che estendono gli editor e utilizzano le API REST possono includere un'azione widget aggiuntiva per richiedere l'accesso ai file. Questa azione richiede che la
funzione di callback dell'azione associata restituisca un oggetto di risposta specializzato:
Per utilizzare questa azione del widget e l'oggetto risposta, devono essere soddisfatte tutte le seguenti
condizioni:
Il componente aggiuntivo utilizza le API REST.
Il componente aggiuntivo presenta la finestra di dialogo dell'ambito del file di richiesta
utilizzando il metodo CardService.newEditorFileScopeActionResponseBuilder().requestFileScopeForActiveDocument().build();.
Il componente aggiuntivo include
l'ambito dell'editor https://www.googleapis.com/auth/drive.file e
il trigger onFileScopeGranted nel manifest.
Richiedere l'accesso al file per il documento corrente
Per richiedere l'accesso ai file per il documento corrente:
Crea una scheda della home page che controlli se il componente aggiuntivo ha l'ambito drive.file.
Per i casi in cui al componente aggiuntivo non è stato concesso l'ambito drive.file, crea un modo per richiedere agli utenti di concedere l'ambito drive.file per il documento corrente.
Esempio: ottenere l'accesso al documento corrente in Documenti Google
L'esempio seguente crea un'interfaccia per Documenti Google che mostra le dimensioni
del documento corrente. Se il componente aggiuntivo non dispone dell'autorizzazione drive.file,
viene visualizzato un pulsante per avviare l'autorizzazione dell'ambito del file.

To implement actions, you must define a widget handler function that triggers a callback function upon a specific condition. This callback function then receives an event object with client-side interaction data and must return a specific response object. For file access, add-ons use a specialized response object, `EditorFileScopeActionResponse`, and need `drive.file` scope in the manifest.\n"],null,["# Editor actions\n\nUse [Action](/workspace/add-ons/concepts/actions) objects to build interactive\nbehavior into Google Workspace add-ons.\n\nAction objects define what happens when a user interacts with a widget\n(for example, a button) in the add-on UI.\n\nAdd an action to a widget\n-------------------------\n\nTo attach an action to a widget, use a [widget handler function](/workspace/add-ons/concepts/actions#widget_handler_functions),\nwhich also defines the condition that triggers the action. When triggered, the\naction executes a designated [callback function](/workspace/add-ons/concepts/actions#callback_functions).\nThe callback function is passed an [event object](/workspace/add-ons/concepts/event-objects)\nthat carries information about the user's client-side interactions. You must\nimplement the callback function and have it return a specific response object.\n\n### Example: Display a new card when a button is clicked\n\nIf you want to add a button to your add-on that builds and displays a new card\nwhen clicked, follow the steps below:\n\n1. Create a button [widget](/workspace/add-ons/concepts/widgets#user_interaction_widgets).\n2. To set a card-building action, add the button widget handler function [`setOnClickAction(action)`](/apps-script/reference/card-service/text-button#setOnClickAction(Action)).\n3. Create an Apps Script callback function to execute and specify it as the [`(action)`](/apps-script/reference/card-service/text-button#setOnClickAction(Action)) within the widget handler function. In this case, the callback function should build the card you want and return an [`ActionResponse`](/apps-script/reference/card-service/action-response) object. The response object tells the add-on to display the card the callback function built.\n\nThe following example shows the creation of a button widget. The action requests\nthe `drive.file` scope for the current file on behalf of the add-on. \n\n```gdscript\n/**\n * Adds a section to the Card Builder that displays a \"REQUEST PERMISSION\" button.\n * When it's clicked, the callback triggers file scope permission flow. This is used in\n * the add-on when the home-page displays basic data.\n */\nfunction addRequestFileScopeButtonToBuilder(cardBuilder) {\n var buttonSection = CardService.newCardSection();\n // If the add-on does not have access permission, add a button that\n // allows the user to provide that permission on a per-file basis.\n var buttonAction = CardService.newAction()\n .setFunctionName(\"onRequestFileScopeButtonClickedInEditor\");\n\n var button = CardService.newTextButton()\n .setText(\"Request permission\")\n .setBackgroundColor(\"#4285f4\")\n .setTextButtonStyle(CardService.TextButtonStyle.FILLED)\n .setOnClickAction(buttonAction);\n\n buttonSection.addWidget(button);\n cardBuilder.addSection(buttonSection);\n}\n\n/**\n * Callback function for a button action. Instructs Docs to display a\n * permissions dialog to the user, requesting `drive.file` scope for the \n * current file on behalf of this add-on.\n *\n * @param {Object} e The parameters object that contains the document's ID\n * @return {editorFileScopeActionResponse}\n */\nfunction onRequestFileScopeButtonClickedInEditor(e) {\n return CardService.newEditorFileScopeActionResponseBuilder()\n .requestFileScopeForActiveDocument().build();\n```\n\nFile access interactions for REST APIs\n--------------------------------------\n\nGoogle Workspace add-ons that extend the Editors and use REST APIs can include an\nadditional widget action to request file access. This action requires the\nassociated action callback function to return a specialized response object:\n\n| Action attempted | Callback function should return |\n|---------------------------------------------------------------------------------------|---------------------------------|\n| [Request file access for current_document](#request_file_access_for_current_document) | `EditorFileScopeActionResponse` |\n\nTo make use of this widget action and response object, all of the following must\nbe true:\n\n- The add-on uses REST APIs.\n- The add-on presents the request file scope dialog using the `CardService.newEditorFileScopeActionResponseBuilder().requestFileScopeForActiveDocument().build();` method.\n- The add-on includes the `https://www.googleapis.com/auth/drive.file` editor scope and `onFileScopeGranted` trigger in its manifest.\n\n### Request file access for current document\n\nTo request file access for the current document, follow these steps:\n\n1. Build a homepage card that checks whether the add-on has `drive.file` scope.\n2. For cases where the add-on hasn't been granted `drive.file` scope, build a way to request that users grant `drive.file` scope for the current document.\n\n#### Example: Get current document access in Google Docs\n\nThe following example builds an interface for Google Docs that displays the size\nof the current document. If the add-on doesn't have `drive.file` authorization,\nit displays a button to initiate the file scope authorization. \n\n /**\n * Build a simple card that checks selected items' quota usage. Checking\n * quota usage requires user-permissions, so this add-on provides a button\n * to request `drive.file` scope for items the add-on doesn't yet have\n * permission to access.\n *\n * @param e The event object passed containing information about the\n * current document.\n * @return {Card}\n */\n function onDocsHomepage(e) {\n return createAddOnView(e);\n }\n\n function onFileScopeGranted(e) {\n return createAddOnView(e);\n }\n\n /**\n * For the current document, display either its quota information or\n * a button that allows the user to provide permission to access that\n * file to retrieve its quota details.\n *\n * @param e The event containing information about the current document\n * @return {Card}\n */\n function createAddOnView(e) {\n var docsEventObject = e['docs'];\n var builder = CardService.newCardBuilder();\n\n var cardSection = CardService.newCardSection();\n if (docsEventObject['addonHasFileScopePermission']) {\n cardSection.setHeader(docsEventObject['title']);\n // This add-on uses the recommended, limited-permission `drive.file`\n // scope to get granular per-file access permissions.\n // See: https://developers.google.com/drive/api/v2/about-auth\n // If the add-on has access permission, read and display its quota.\n cardSection.addWidget(\n CardService.newTextParagraph().setText(\n \"This file takes up: \" + getQuotaBytesUsed(docsEventObject['id'])));\n } else {\n // If the add-on does not have access permission, add a button that\n // allows the user to provide that permission on a per-file basis.\n cardSection.addWidget(\n CardService.newTextParagraph().setText(\n \"The add-on needs permission to access this file's quota.\"));\n\n var buttonAction = CardService.newAction()\n .setFunctionName(\"onRequestFileScopeButtonClicked\");\n\n var button = CardService.newTextButton()\n .setText(\"Request permission\")\n .setOnClickAction(buttonAction);\n\n cardSection.addWidget(button);\n }\n return builder.addSection(cardSection).build();\n }\n\n /**\n * Callback function for a button action. Instructs Docs to display a\n * permissions dialog to the user, requesting `drive.file` scope for the\n * current file on behalf of this add-on.\n *\n * @param {Object} e The parameters object that contains the document's ID\n * @return {editorFileScopeActionResponse}\n */\n function onRequestFileScopeButtonClicked(e) {\n return CardService.newEditorFileScopeActionResponseBuilder()\n .requestFileScopeForActiveDocument().build();\n }"]]
