Detailed Description

TxtExpDialogObserver Allows dynamic processing of dialog widget changes, in this case the dialog's info button.

Implements IObserver based on the partial implementation CDialogObserver.

Constructor & Destructor Documentation

TxtExpDialogObserver::TxtExpDialogObserver ( IPMUnknown *  boss )

inline

Constructor.

Parameters

boss	interface ptr from boss object on which this interface is aggregated.

virtual TxtExpDialogObserver::~TxtExpDialogObserver ( void  )

inlinevirtual

Destructor.

Member Function Documentation

Binds the C implementation class onto its ImplementationID making the C code callable by the application *void TxtExpDialogObserver::AutoAttach ( void  )

virtual

Called by the application to allow the observer to attach to the subjects to be observed, in this case the dialog's info button widget. If you want to observe other widgets on the dialog you could add them here.

Reimplemented from CDialogObserver.

void TxtExpDialogObserver::AutoDetach ( void  )

virtual

Called by the application to allow the observer to detach from the subjects being observed.

Reimplemented from CDialogObserver.

void TxtExpDialogObserver::Update ( const ClassID &  theChange, ISubject *  theSubject, const PMIID &  protocol, void *  changedBy  )

virtual

Called by the host when the observed object changes, in this case when the dialog's info button is clicked.

Parameters

theChange	specifies the class ID of the change to the subject. Frequently this is a command ID.
theSubject	points to the ISubject interface for the subject that has changed.
protocol	specifies the ID of the changed interface on the subject boss.
changedBy	points to additional data about the change. Often this pointer indicates the class ID of the command that has caused the change.

Reimplemented from CDialogObserver.
