Annotation Event

[User (Legacy)]

We are using the Client Server edition of ChartFX. How can we let Chart

Object to handle Annotation events?

You need to attach to the appropriate event. For example:

[C#]

{

    ...

    annotationX.ObjectCreated += new

AnnotationEventHandler(annotation_ObjectCreated);

    ...

}

private void annotation_ObjectCreated (object sender, AnnotationEventArgs e)

{

}

Thanks for the answer. I am using ChartFX Client Server edition in VC++. I

added an event handler to the chart. The event handler handles all standard

chart events properly. It does not handles any annotation events. Here is my

code.

class CMyChartEvents : public ICfxEvents

{

    ...

   // Annotation. I also added following code to CfxEvents.h.

  // I don't know the correct format. I tried both sets. I may be wrong

here.

    STDMETHOD(ObjectCreated)(struct IAnnObject * /*pObj*/) { return

S_FALSE; }

    STDMETHOD(Fire_ObjectCreated)(struct IAnnObject * /*pObj*/) { return

S_FALSE; }

    ...

}

In the chart class,

 CDAChartEvents *pEv = new CMyChartEvents();

 pChart->raw_SetEventHandler((LPUNKNOWN) pEv,NULL);

 pEv->Release();

They don't work for annotation. Is there a way to add event handler to the

Annotation extension in VC++, like in C#?

Thanks.

We don't have a similar interface for annotation.

The only way to capture events for the annotation extension is through

standard COM events.

We don't have a sample on this, you can check MSDN's docs on "Events in COM

and Connectable Objects" under:

"Platform SDK Documentation/Component Services/COM Fundamentals/Guide/Events

in COM and Connectable Objects"
