# GlideDialogWindow- Client \(deprecated\)

The GlideDialogWindow API provides methods for displaying a dialog in the current window and frame.

Use these methods in scripts anywhere that you can use a client-side JavaScript. These methods are most often called from a UI action with the **Client** check box selected.

**Note:** This API has been deprecated, use the [GlideModal](https://raw.githubusercontent.com/ServiceNow/ServiceNowDocs/brazil/markdown/api-reference/c_GlideModalV3API.md) API instead.
