How to know if an entity’s properties are modified by the OPM?

By Philippe Leefsma

Q:

How would one know if an entity’s properties are modified by the OPM?

A:

OPM brackets the property modification calls with modeless operation start/end notifications using the string "OPM_CHGPROP".

Applications should receive these notifications through the AcEditorReactor::modelessOperationWillStart() and AcEditoReactor::modelessOperationEnded()
