[Gtk-sharp-list] portability issues
Fri, 22 Oct 2004 15:00:32 +0100
After a lot of discussion on #mono @ irc.gnome.org and a bunch of google
searchs, I got this message on mono-list:
Of course the problem is the same - GTK isn't thread-safe and we're
trying to deploy a gui-multithreaded app, but what this guy hadn't
discovered was Gdk.Threads. With a Gdk.Threads.Enter() before the
Gtk.Application.Init(), and Gdk.Threads.Enter() plus <GTK-update-works>
plus Gdk.Threads.Leave(), we are able to create a special place for gui
updating outside the GTK mainloop.
The compatibility issues, were discussed and it seems that Gdk is not
fully ported to Windows in gtk-2.2.x, which is the actual bundled
version with mono.
What I am trying to do, is to simply install a previous
mono-combined-installer with GTK-2.4.x and try to run the app. I'll get
the feedback to the list in a few minutes!
Btw, gtk-2.4.x is not bundled with mono anymore because of glade
backwars compatibility, since some widgets created in glade-2.6.x are
non-existant in its previous versions, p.e.: GtkToolItem, GtkToolButton,
So many thanks to paco for the patience, to tremor for the
mono-combiner-installer and francis for the workaround :)
