File upload

The File wiget is an input widget that allows the app user to upload files from any device.

On a computer screen, the user is automatically directed to the file browser. In the mobile version, this widget also supports a camera feature (similar to the Photo widget).

Settings

When empty, the File widget looks like a regular Button, and all of the visual settings are the same as the button's.

The settings specific to uploading files are:

  • Storage type: Allows choosing between file and buffer storage types.

    • When choosing file the file is saved into the runtime-files folder, and the function connected to the widget will show the exact path it is saved in.

    • When choosing buffer the document is compressed into a Base64 string, which will be shown in the connected function instead of the file path.

  • Multi-File Upload:

    • Check the Allow multi-file upload box to allow uploading multiple files.

    • Set a Maximum number of files to limit the files a user can upload at once.

  • Thumbnails:

    • Allow Thumbnails: By default, the file preview shows the file names. When Allow Thumbnails is checked, the preview will be a thumbnail of the files.

    • Thumbnail size: Thumbnail size can be customized in this setting.
