# OnAboutScript

The **OnAboutScript** event can be implemented by a [script add-in](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/script_add-ins) to display an "about" dialog to the user. It is triggered when the user clicks the *About* button for a script on the [**Script Management**](https://chaoses-ib.gitbook.io/directory-opus/manual/scripting/script_management) dialog.

| **Description:**   | The usual implementation for this event would use the **AboutData.window** parameter to display a dialog using the [**Dialog**](https://chaoses-ib.gitbook.io/directory-opus/manual/reference/scripting_reference/scripting_objects/dialog) object. |
