Type

BackConversion: ((val: any, sourceData: any, model: Model) => any) | null

For bindings: The optional conversion function to convert property values back to data values. Specifying this function modifies a binding to set its Binding.mode to be Binding.TwoWay. If you want a two-way binding without a back-conversion function, specify null for a BackConversion. If you do not want a two-way binding, omit any BackConversion.

BrushLike: Brush | string | null

The BrushLike type is the same as Brush | string | null. A string in place of a Brush object is treated as a Solid Brush of that color.

DiagramInitOptions: Partial<Diagram | { [ P in DiagramEventName]?: (e: DiagramEvent) => void } | DiagramInitStrings>

DiagramInitOptions are used in the Diagram constructor to concisely initialize a Diagram by settings its properties, and also set properties on its Tools, CommandHandler, AnimationManager, and set DiagramEvents.

Key: string | number | undefined
