AI-generated from the code · Odoo 15.0

Shows a larger version of an image when hovering over image fields in list (tree) views. A demo view adds an image column to the Users list so hovering it displays the bigger picture.

This module changes how image fields behave in list views. When a list contains an image field, hovering the mouse over the small image opens a tooltip showing a larger image, so users can preview a picture without opening the record.

  • The tooltip image is taken from the field named in the field's options (for example, a small image can show a bigger image field as its tooltip).
  • The tooltip appears immediately on hover and disappears when the mouse leaves.
  • The module also sets a default width for these images in list views.

A demonstration view is included: it adds an image column to the Users list (res.users) and configures it so that hovering the small image shows the larger one. This is only a demo of how to configure the feature; the module itself does not add menus or new screens.

The change applies to any list view where an image field is configured with the tooltip option, so it can be used on customers, products, employees or any other model with image fields. No new database models, menus, reports, emails or scheduled actions are added.
