Space Navigator for Notebooks working as a background app

[superbigio]

Hi there,

I recently bought a Space Navigator for Notebooks and I want to integrate its functionality in an application.
The idea is to get something that supports multiple devices as well. I see that is possible with the Max OS X API.

I am writing some driver code to capture the data sent by the SN and I run into a problem.
When the app in question is not the frontmost app I stop receiving data from the SN.

If I initialize the device with the following code:

clientID = RegisterConnexionClient('max2', NULL, kConnexionClientModeTakeOver, kConnexionMaskAll);

I receive data normally, but only if the app is frontmost.

This is the code that - according to the docs - should allow me to receive data no matter if the app is frontmost or in the background:

clientID = RegisterConnexionClient(kConnexionClientWildcard, NULL, kConnexionClientModeTakeOver, kConnexionMaskAll);

However, in this case I don't receive anything at all.

What am I doing wrong ?

Thanks.

ok, nevermind... my bad.
I was doing something silly and figured out the mistake.

Now, just to clarify:

if I register my client as follows:
clientID = RegisterConnexionClient('max2', NULL, kConnexionClientModeTakeOver, kConnexionMaskAll);

then I only receive events when my application ('max2') is in focus,

whereas, if I use:
clientID = RegisterConnexionClient(kConnexionClientWildcard, NULL, kConnexionClientModeTakeOver, kConnexionMaskAll);

then I receive events whether we are in focus or not. Correct ?
In this mode why would I need a client ID ? Can I safely disregard it ?

Thanks.
