Re: [Vala] Signals not being called back

[Michael Starkweather <mpstark gmail com>]

I noticed after your response (thank you for that when I canceled the
Timeout by returning false from the callback that the libbamf signal
callbacks also stopped, which I found curious, because if it was a setup
thing and if the Timeout was doing some sort of setup, then surely after
the Timeout ended, the setup would remain. So I was typing up a confused
email containing a simple diagram with the relationships and call order of
everything because I was sure more than ever that I was doing it right.

In creating this diagram, I noticed that my object containing the callbacks
(ApplicationProcessModel) was created locally (by accidentally including
the keyword var in front of it) and the reference was never held causing
the object to be destroyed when it dropped out of scope. When I created the
Timeout in the constructor, it was holding a reference to the locally
created object that it needed to callback to, causing it to live until the
Timeout was canceled. My Gtk.TreeView still held a reference to the
Gtk.TreeStore that had been stored in this object, so it never occurred to
me that the rest of the object was simply going away. What an odd problem.


Thanks for your time!
