[pygtk] gobject.io_add_watch buffered?

[Gabriele Lanaro]

Now it's ok, with the flush() method the program give me the string every 2 seconds, but I have another problem:
I substitute the print text in the gobject.io_add_watch callback with a thing like this:
----------------- -----------------------------------
class CodeLauncher
    def __init__(self,executable,self.args):
	# WIDGET DEFINITIONS, there is also the window etc..
	tv=gtk.TextView()
	self.buffer=tv.get_buffer()
    def run(self):
        p=subprocess.PIPE
        cmdline=self.executable,self.args
        child=subprocess.Popen(cmdline,stdout=p)
        gobject.io_add_watch(child.stdout,gobject.IO_IN | gobject.IO_HUP,self.writeout,priority=gobject.PRIORITY_HIGH)
        gtk.main()
    def writeout(self,file,event):
        text=1
        while text:
                text=file.readline()
                iter = self.buffer.get_end_iter()
                self.buffer.insert(iter,text)
-------------------------------------------------------
Now the problem is that the output of the program is visualized only when the program spawned (ex. blocking.py with flush)returns..and in the middle the interface is blocked.
Maybe I've forgotten something...
