Uhm... I'm actually using this to read the make ouput
def compile_kernel(self, widget):
textbuffer = gtk.TextBuffer()
fin = os.popen("uname -r")
ker_ver = fin.readline()
fin.close()
self.compile_status.set_buffer(textbuffer)
fin = os.popen("cd /usr/src/linux && make && make modules_install && cp
arch/i386/boot/bzImage /boot/bzImage-" + ker_ver)
line = None
while line != '':
line = fin.readline()
textbuffer.insert_at_cursor(line)
fin.close()
return
I've never knew anything about gobjects, have you got some kind of reference
(possibly an example)?
Thanks

Greetings everyone, I've just began PyGTK developing today and I started to get my GTKmm kernel compilation utility "ported" to PyGTK. In order to display the make ouput I used a particular Glib method (spawn_async_with_pipes). I've tryed looking around, but I didn't find any equivalent, so I hooked up the old popen(), wich, of course, freezes the window during the make process. Does anybody know a way to display the popen output while the process is running?
