[pygtk] problem with textview.get_iter from another thread
Hi. First of all I'm quite new to python and pygtk. Anyway, there seems
to be a problem with getting textbuffer iters from another thread than
gtkmainloop's. Here is a fast written little piece of code testing this
operation :
-- test.py
import threading
import time
import pygtk
pygtk.require('2.0')
import gtk
class CGuiModifyThread(threading.Thread):
def __init__(self, gui):
threading.Thread.__init__(self)
self.gui = gui
self.done = 0
def run(self):
i = 0
while (i 10):
i = i + 1
gtk.threads_enter ()
gui.addpage_cb(None)
gtk.threads_leave ()
time.sleep(.2)
Done = 1
print Thread done
class CGui(gtk.Window):
def __init__(self):
gtk.Window.__init__(self, gtk.WINDOW_TOPLEVEL)
self.connect(destroy, self.destroy_cb)
self.vbox = gtk.VBox()
self.add(self.vbox)
self.checkbutton = gtk.CheckButton(Try to get iter)
self.checkbutton.set_active(1)
self.vbox.pack_start(self.checkbutton, gtk.FALSE, gtk.FALSE, 0)
self.startbutton = gtk.Button(start thread)
self.startbutton.connect(clicked, self.start_cb)
self.vbox.pack_start(self.startbutton, gtk.FALSE, gtk.FALSE, 0)
self.addpage = gtk.Button(Add page to notebook)
self.addpage.connect(clicked, self.addpage_cb)
self.vbox.pack_start(self.addpage, gtk.FALSE, gtk.FALSE, 0)
self.notebook = gtk.Notebook()
self.vbox.pack_start(self.notebook, gtk.FALSE, gtk.FALSE, 0)
self.startbutton.show()
self.addpage.show()
self.notebook.show()
self.vbox.show()
def start_cb(self, data):
print Starting thread
self.modifyth = CGuiModifyThread (self)
self.modifyth.start()
def destroy_cb(self,*args):
self.hide()
gtk.mainquit()
def addpage_cb(self, data):
textview = gtk.TextView()
textbuffer = gtk.TextBuffer(None)
textview.set_buffer(textbuffer)
if (self.checkbutton.get_active()):
print Getting iter
iter = textbuffer.get_iter_at_offset(0)
print Done
textbuffer.insert(iter, Hello World\n)
self.notebook.add(textview)
textview.show()
gtk.threads_init ()
gtk.threads_enter ()
gui = CGui()
gui.show_all()
gtk.mainloop ()
gtk.threads_leave()
-- end
If you dont get iter while running thread, everything's OK. If you get
iter from the mainloop it's ok. But if you get iter from a child thread
everything freezes.
Is there any big mistake in this code (except it was made in 2 minutes)?
Thanks

[pygtk] pthread error with pygtk
I've got pygtk-0.6.10 installed on FreeBSD 4.6.2 with python 2.2.2, gtk-1.2.10, and pth-2.0.0. Things were working well before, until I upgraded some of my software packages. Among other things, I believe I upgraded pth from version 1.4. Since upgrading, things that use pygtk no longer work, even though I've reinstalled all the relevant stuff to make sure it's up to date and properly compiled. Here's an example of what I'm seeing: python Python 2.2.2 (#1, Mar 24 2003, 15:55:57) [GCC 2.95.3 20010315 (release) [FreeBSD]] on freebsd4 Type help, copyright, credits or license for more information. import gtk Traceback (most recent call last): File stdin, line 1, in ? File /usr/local/lib/python2.2/site-packages/gtk-1.2/gtk.py, line 22, in ? import _gtk ImportError: /usr/local/lib/pth/libpthread.so.20: Undefined symbol sigaltstack I have no idea what the problem here is, or how to solve it. Any suggestions would be most welcome. Please cc: me, as I am not currently subscribed.

[pygtk] Problem with iter and Tree/list model
Hello mailing list
I have just released one of my programs to the public and have recieved
an error message from a user I can't reproduce.
I hope someone can help with the problem regarding iteration in
a ListStore.
The Save function in the class i the buttom of this mail which inherit
from gtk.ListStore works on my pygtk 1.99.11 but fails on his 1.99.16
with an error:
File /usr/local/bin/pyblink, line 104, in save
r=self.get_value(iter,0)
TypeError: iter must be a GtkTreeIter
Can any one see any logical error in the way the iteration is done.
I must admit i have done som guessing since the docs aren't that good.
Another (maybe related) problem is how to build the list.
What is the difference between:
iter = self.append ()
self.set (iter, 0, ref)
and
iter = self.append ()
self.set_value (iter, 0, ref)
I hope someone can help.
Regards Thomas
