Thanks for the quick response. Reading the book "Rapid GUI programming with
Python and QT" in the section "Signals and Slots" (page 127) the author
starts the section by stating:
"Every GUI library provides the details of events that take place ..."
So I gathered that SIGNALS were events. Apparently, I did not understand
completely. Could you take a little more time and explain why they are not.
There is more to read - chapters 10 and 11 are suppose to get deeper into the
SIGNALS and SLOTS.
Still would like to know where I can see a list of SIGNALS?
