Callback - Active Renderer Changed, Signal Property Value Changed


The script on this page is included by a script embedded within, and executed by, a DzCallBack that is connected to the activeRendererChanged(DzRenderer*) signal on DzRenderMgr. Several variables used in this script are assumed to be defined in the script that includes this script.

The purpose of this script is to find a (predefined) target DzProperty on a (predefined) target DzRenderer and cause the currentValueChanged() signal to be emitted (thereby triggering updates between associated properties).
