Hi Aitor et al,

I created gtk3 application but have problems connecting events to
signals using the infamous:

gtk_builder_connect_signals (builder, NULL);

No signals are connected making the application terminate without
proper cleanup.
The central part of GUI programming seems to be also the most
contorted and mysterious part. In Delphi and Lazarus Pascal,
implementing an event handler is a matter of a few mouse clicks, or at
most, an assignment of a procedural variable to the component.onclick
property.
