ThemeManager

Defined in: theme/ThemeManager.ts:12

GoJS-compatible: manages a Diagram’s (or several Diagrams’) set of named Themes and which one is active. Templates read theme values via GraphObject.theme()/themeData()/themeModel() (which attach a ThemeBinding), or by calling findValue/getValue directly.
