Subject: GTK2 example in the cookbook doesn't show anything.
Hello, I tried the first example code for GTK2 from the cookbook(http://poe.perl.org/?POE_Cookbook/Gtk2_Counter) , it run without errors, but only show an empty window. Following some tips from #poe, I added a small pause between ev_count events.It fixed the problem. I changed the last line of ui_count() from : $kernel->yield("ev_count"); to $kernel->delay("ev_count",2); I use gtk2-perl 1.203, perl 5.10.1, on linux 2.6.31(gentoo) .

actually, that's the wrong solution. you shouldn't need the delay (it used to work without before)

Argh! At least on my system, I tried various schemes and got those results: yield # Gtk2 window pops up, but no data in it and 100% cpu delay => 1 # works delay => 0.1 # works delay => 0.01 # works delay => 0.001 # same result as yield So I assume somehow the internals of Gtk/Glib/whatever can't handle the insanely fast update rate? Martijn, do you remember what version of POE/Gtk/Glib/etc worked with yield? I'l leave this ticket as stalled for now until someone with more experience in the internals of Gtk/Glib can help :) -- ~Apocalypse
