GlgTraceListener Class Reference

Detailed Description

GlgTraceListener is an object used by the GlgObject::AddListener method to attach listeners of the TRACE_CB and TRACE2_CB types (defined in the GlgCallbackType enum).

These listeners are invoked on any event in the GLG viewports, allowing to implement custom event handling logic.

The object's TraceCallback method defines the type signature of the function that needs to be passed as a parameter of the GlgObject::AddListener method to add a trace listener.
