Re: threads and trayicon error

[anguila <anguila gmail com>]

so the mistake in my code is use threads?I thought that maybe I used bad some function :\ I will try with this way (mentioned in the gtk2-perl faq), but it's weird that the trayicon changes good and after X (unknow) time crash and this icon becomes a line :\ with any reason

I'd suggest not using threads for this purpose... too complicated and
error-prone. It's not allowed to call Gtk+ functions outside the thread
which started the main loop, so you need to start a pure worker thread
communicating with the main thread to update the GUI etc.

You already have a separate process for the http stuff, so it's easy to
install an I/O watcher on your pipe and response to the events instead
of struggling with threads.

That's very common and you find an example for this in Gtk Perl docs,
e.g. here:

Think before you code. And while you're doing it probably won't hurt. ;)
