Hi Klugier,
thank you for your support.

First of all, I am not 100% sure how the logging works. I activated the logs removing the // on the line #define LOG_EVENTS. Then I looked in all the files in /var/log/ (standard directory for logs in linux) and found nothing. I found a log file in ~/.upp/name_of_my_application/name_of_my_application.log but it contained only SQL log. At the end I noticed that gtk events were logged directly in the console the application was launched from.

Any way, that is what I found out:

Single tap on a Switch control: nothing logged

Single tap on a button where the WhenPush callback is defined:

Single tap on a button where the WhenPush callback is not defined: nothing

Double tap:

Any ideas?
