# OnAboutScript

The **OnAboutScript** event can be implemented by a [script add-in](../../../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**](../../../scripting/script_management) dialog.
