[pygtk] Threads and applets (gnome.applet)
Hi,
I've recently encountered some problems with threads in a (python) gnome
panel applet. My problem is that any spawned threads don't seem to get
scheduled and consequently never run (at least, not until the gtk
mainloop exits). A simple example:
=
#!/usr/bin/python
import sys
sys.stdout = open('debug', 'w') # redirect stdout/stderr to a file
sys.stderr = sys.stdout
import gtk
gtk.gdk.threads_init() # (!)
import gnome.applet
import gobject
import thread
import time
class AppletClass(gnome.applet.Applet):
def __init__(self, applet, iid):
self.__gobject_init__()
self.applet = applet
self.label = gtk.Label('Hello World')
self.applet.add(self.label)
thread.start_new_thread(self.thread_function, ())
def thread_function(self):
sys.stdout.write('Thread started.\n')
sys.stdout.flush()
while True:
sys.stdout.write('I like threads.\n')
sys.stdout.flush()
time.sleep(1)
gobject.type_register(AppletClass)
def class_applet_factory(applet, iid):
AppletClass(applet,iid)
return gtk.TRUE
gnome.applet.bonobo_factory("OAFIID:GNOME_PythonAppletSample_Factory",
AppletClass.__gtype__,
"hello", "0", class_applet_factory)
=
I expect this applet (with the appropriate bonobo .server file) to show
a "Hello World" label in the panel and write "I love threads." to stdout
(which is redirected to a file "debug" in this case). The widget part
works fine, but the stdout thread is never run (nothing written to stdout).
Points to note:
* My applet (of which the above is a highly simplified version) used to
work; a recent update of gnome-python seems to have broken it, but I'm
not sure exactly when.
* For threaded applications, gtk.gdk.threads_init() is supposed to be
called before gtk.main, but in the case of an applet, aren't we already
inside gtk.main? Can/should the threads_init call be moved elsewhere?
* I'm running Debian (unstable), relevant packages:
python2.3-gtk2 (2.4.1-2)
python2.3-gnome (2.6.1-1)
python2.3 (2.3.4-19)
libgtk2.0-0 (2.4.14-2)
libgnome2-0 (2.8.0-6)
Does anybody know what/where the problem might be? Is it most likely a
problem with gtk+, gnome, pygtk, pygnome or the Debian packaging?
thanks,
brad

They can, but doing so would be an api change and would break existing code. There was some discussion of setting things up so that self.props. could be used to get / set gobject properties, but nothing has been implemented AFAIK.

[pygtk] UIManager: missing control
Hi all, after updating my GTK+ libraries to 2.6 and PyGTK to 2.5 I started getting lots of deprecation warnings (again). The noisy way they're presented helped me deciding that I might as well do a major rewrite of my program to not just fix some minor problems but incorporate some bigger wishes as well. With the ItemFactory falling from grace and UIManager rising, I managed to get a first boilerplate of the UI rather quickly (couldn't have done it without the appwindow.py example in the examples directory of PyGTK, though). Alas, I'm missing a lot of control over the appearance of menus and toolbar buttons: It seems there's no way to switch of the icons in the menus and/or the labels in toolbar buttons. These buttons are easily twice the size of my older app (with the same 24x24 pixmaps!). Once I had room to spare, now they don't fit on 2 toolbar rows. Maybe if I created different action groups, but wouldn't that be against the very reason for their existance? Of course there's always the chance I overlooked something.

buf = gtk.TextBuffer()
[...]
insert = buf.get_mark('insert')
iter = buf.get_iter_at_mark(insert)
'insert' is a special mark used to track the cursor position. It is
builtin in the GtkTextBuffer.

I have no idea if this is the best way to do it. But this is what I am
doing and it works fine for me. This code is from a project that defines
a TextView called file_textview using glade. But the signal handler is
attached in the code rather than in glade.
def init_text_display(self):
self.text_view = self.widgets.get_widget('file_textview')
self.text_buffer = self.text_view.get_buffer()
self.text_buffer.connect('mark-set', self.on_insertion_moved)
def on_insertion_moved(self, text_buffer, iter, text_mark):
# see if the cursor has really moved
offset = iter.get_offset()
if self.last_offset != offset:
self.last_offset = offset
# processing here
