OverlayWindow

Description

Supported Script Types: Interface Scripts • Client Entity Scripts • Avatar Scripts

A OverlayWindow displays a QML window inside Interface.

The QML can optionally include a WebView control that embeds an HTML-based windows. (The WebView control is defined by a "WebView.qml" file included in the Interface install.) Alternatively, an OverlayWebWindow can be used for HTML-based windows.
