Detailed Description

IdfObjectWatcher watches an IdfObject for signals emitted on changes.

These signals will cause the watcher to mark the IdfObject as dirty. The dirty flag will persist until reset by the user. Virtual methods onChangeIdfObject and onDataFieldChange are also available to override. The former is called every time the IdfObject changes in any way; the latter is called whenever a data field changes (not triggered by comment changes, and is superceded by onRelationshipChange for WorkspaceObject pointer fields.) The virtual method onBecomeDirty is called only after dirty transitions from false to true. Alternatively, the virtual method onBecomeClean is called only after dirty transitions from true to false.

IdfObjectWatcher is an atypical QObject because it is designed to be stack allocated. In many cases it would be preferred to connect your own heap allocated QObject to the Workspace signals directly rather than using this convenience class.
