Detailed Description

Runs the snippet when the go button is clicked, also when the name of the snippet to be run is changed this observer uses ISnipRunSuite::CanRun to determine if the snippet can run and enables or disables the button accordingly.

The name of the snippet this implementation works with is given by the IStringData interface aggregated onto this control's boss class as IID_ISNIPRUNSNIPPETNAMESTRINGDATA. To get this observer to recognise a change to this data client code should call this button's ISubject as shown:

ISubject::Change(kTextChangeStateMessage, IID_ISNIPRUNSNIPPETNAMESTRINGDATA);

Implements IObserver based on the partial implementation CObserver.

Member Function Documentation

void SnipRunGoButtonObserver::AutoAttach ( void  )

virtual

Attaches observed subjects. Observes the button's ITriStateControlData to catch clicks and the IID_ISNIPRUNSNIPPETNAMESTRINGDATA to catch when the name of the snippet to be run changes.

Reimplemented from CObserver.

void SnipRunGoButtonObserver::AutoDetach ( void  )

virtual

Detaches observed subjects.

Reimplemented from CObserver.

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

virtual

An observed subject has changed.

Implements IObserver.
