Hi!

I'm using Ink with Delphi.

I wrote a OnNewInAirPackets event handler and it nevers gets fired.

I tested it with C# and it is fireing correctly.

Anyone knows why?

Thanks

VB

Hi Vincent,

I am not very familiar with Delphi, but I assume you are using the COM Ink
API (in InkObj.dll) from your Delphi environment, correct?

When using the COM API, you have to tell the Ink collection object
(InkPicture, InkOverlay or InkCollector) which of the optional events you
want to receive. To do so, please call the SetEventInterest method [1] on
your InkPicture control.

Specifically, the NewPackets and NewInAirPackets events are expensive from a
performance perspective as they fire with high frequency. Thus we do not
produce them by default - you only receive them if you explicitely ask for
them.

In a managed code environment (like C# or VB.NET) we manage the event
interest automatically behind the scenes for you: if we see that an event
handler for an optional event is attached, we'll start producing the
events - making this transparent to the user. Thus your C# application does
receive the events without any extra API calls.
