Thank you so much Koen.
The scanner is not connected anymore for me to debug, but when I debugged
earlier I remember $4 had the pointer value ->__qpix_acq_array_long. This
had the required array elements for setting up the event information.
Similarly, it had values for all the other events too.
Nisha,
If you set a break point in the case of branches, can you see what you get in
$4 at runtime?
You might need to contact the developer of QPix to get this solved.

Thanks Koen,
You are right, it is the QPix. You are also right about the event constants.
They are correct in the code, looks like while pasting from MAC to the
screen here I made a mistake. Sorry for that.
In the actual code, it is

: ($event=qpx_AcqImageSaved)

Ah, a bit more complex as it is a callback method called from a
plugin/component. I guess QPix?
Are you sure the event constants are the correct ones?
: ($event=imageSaved)
: ($event=resolution)
: ($event=pixelFormat)
I've never used this plugin, but in the online manual I found
