# Perspective - View Canvas Scripting

> This page details the various scripting, component, and extension functions available for [Perspective's View Canvas](perspective-view-canvas.md) component.

## Component Events

The [Perspective Event Types Reference](appendix/reference-pages/perspective-event-types-reference.md) page describes all the possible component event types for Perspective components. Not all component events support each Perspective component. The [Component Events and Actions](ignition-modules/perspective/working-with-perspective-components/component-events-and-actions.md) page shows how to configure events and actions on a Perspective component. Component scripting is handled separately and can be accessed from the Component menubar or by right clicking on the component.
