Feature Request: Add Basic Yes/No Prompt Support

[executed]

Context:

The Nextcloud Calendar app currently includes a simple Yes/No confirmation dialog when performing actions like emptying the trashbin. However, this functionality relies on a deprecated, custom internal implementation of a confirm dialog. Developers are now encouraged to use the nextcloud-libraries/nextcloud-dialogs library, but this library does not currently provide built-in support for a basic Yes/No confirmation prompt.

This lack of support limits the ability to integrate simple confirmation dialogs into Nextcloud Calendar or other apps in a clean and maintainable way.

Proposed Solution:

Enhance the nextcloud-libraries/nextcloud-dialogs library by adding support for basic Yes/No confirmation dialogs. This feature should:

Provide an API for simple confirmation prompts:

Allow developers to easily create a dialog with customizable text and "Yes"/"No" button labels.

Return a promise or similar mechanism to handle the user’s response (e.g., resolve with true for Yes, false for No).

Example API:

nextcloudDialogs.confirm({ message: "Are you sure you want to proceed?", title: "Confirm Action", confirmButton: "Yes", cancelButton: "No" }).then(result => { if (result) { // User clicked "Yes" } else { // User clicked "No" } });

Example Use Case:

In the Nextcloud Calendar app, when an action like deleting an event or emptying the trashbin is performed, a Yes/No confirmation dialog can be shown using the new API. This dialog would replace the current deprecated implementation, providing a cleaner and more future-proof solution.Other than that I'm currently working on another confirmation dialog when resizing/dropping calendar event that is part of recurring series should ask user "Update future events too?".

Whats the problem with just using the dialog builder? https://nextcloud-libraries.github.io/nextcloud-dialogs/classes/index.DialogBuilder.html
