I am trying to write a threaded applet with PyGTK, starting up a thread
to get data off the Internet without blocking the UI.
Here is a simple example of the type of threading I am trying to do:
#!/usr/bin/python
import gtk, gnome, gnome.applet, thread
def do_thread_cb(mutable):
mutable[0] = "Success!"
def set_label_cb(mutable, widget):
widget.set_text(mutable[0])
def applet_factory(applet, iid):
gtk.gdk.threads_init()
label = gtk.Label("trying...")
applet.add(label)
applet.show_all()
mutable = ["failed"]
gtk.timeout_add(1000, set_label_cb, mutable, label)
thread.start_new_thread(do_thread_cb, (mutable, ))
return gtk.TRUE
gnome.applet.bonobo_factory("OAFIID:GNOME_TestApplet_Factory",
gnome.applet.Applet.__gtype__,
"hello", "0", applet_factory)
The problem is that while this runs fine, when I try to remove the
applet from the panel using the right-click menu, I get an error dialog
and:
Fatal Python error: PyThreadState_Get: no current thread
I tried moving the gtk.gdk.threads_init() to the main body of the applet
(before gnome.applet.bonobo_factory) but in that case the thread seems
not to run at all.
Has anyone successfully created a threaded applet with PyGtk? Am I doing
something wrong here?
Thanks,
Ed Catmur.
