The .read() method in Python reads the whole file, not just the first
line.
read() will also read from the current position so you can keep reading
as new data is added. An alternative is to not open the file in
refreshLog but when initializing and then read it in refreshLog which is
called by timeout_add - something like:
Code:
textview = self.gui.get_widget(bottom_textview)
# Methods that need to be run on start
file = open('log.txt')
self.refreshLog()
# Timer to autorefresh log
timer = gobject.timeout_add(500, self.refreshLog)
timer.start()
def refreshLog(self):
string = file.read()
if string:
buffer = textview.get_buffer()
mark = buffer.create_mark(end, buffer.get_end_iter())
textview.scroll_to_mark(mark, 0)
buffer.insert_at_cursor(string)
buffer.delete_mark_by_name(end)
return True

[pygtk] [Fwd: PyGTK in Vista?]
---BeginMessage--- Hi, I have tried to install PyGTK in Microsoft Windows Vista but failed.

At the end however, they tell me that it is installed. From python, I get DLL load failed when I do import gtk. I am in no way a Windows Vista expert, I just thought it would be nice to be able to also run my graphical python applications both on Linux and on Windows.

Thank you all for the replies. I was not aware of the problems with the
threading in GTK+.
I got it working perfectly using the gobject timeout with Johns modified
routine. I now only have to insert new text from the log and dont have
to reread the whole thing.
Thanks!

You have it working now so this isn't really relevant. However, I had
success using gnome.vfs.monitor_add. It can call your event handler
in several situations, I used MONITOR_EVENT_CHANGED to find out when
my log files changed. I keep track of the current file position each
time so I open, seek to that position, read, close, record the new
position and add the data to the text buffer. No polling necessary.
And I assume that the gnome.vfs call is doing a select so it should
be much more efficient.
Thanks!

You probably should explicitly decide how to handle \0. If it's always
at the end, it's probably just a simple bug and can be chopped off but
it may be something more if valid text follows the \0.
But in general, I think this'll work:
def valid_glib_utf8(s):
try:
unicode(s, 'utf-8')
except Exception:
return False
else:
return '\x0' not in s
In case you need it s.replace('\x0', '') will remove the \0's.
Cheers,
John
That doesn't work:
import gtk
tv = gtk.TextView()
b = tv.get_buffer()
t = test\x00
u = unicode(t, 'utf-8')
b.set_text(t)
__main__:1: GtkWarning: gtk_text_buffer_emit_insert: assertion
`g_utf8_validate (text, len, NULL)' failed
it's the same if I try with the unicode:
import gtk
tv = gtk.TextView()
b = tv.get_buffer()
t = test\x00
u = unicode(t, 'utf-8')
b.set_text(u)
__main__:1: GtkWarning: gtk_text_buffer_emit_insert: assertion

[pygtk] ListStore iter vs. path
I'm just starting to learn PyGTK and GUI programming in general, and Tree/ListViews confuse me tremendously. One question I have is, what's the difference between iters and paths? It seems like paths are much easier to use, because I can simply use model[path][column] to access any part of the ListStore. Is there any way to get the current selection as a path rather than an iter? signature.asc Description: This is a digitally signed message part ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/

GnomePython 2.21.0 has been just released. This a development release for testing. I am especially interested in people testing the new WAF build system.

Currently the list of provided python modules includes: - gnome, gnome.ui - gnomecanvas - gnomevfs - gconf - bonobo, bonobo.activation, bonobo.ui Overview of Changes from gnome-python 2.20.1 to gnome-python 2.21.0 * Bug 462884 – Add support for get_file_mime_type. * Bug 467688 – Binding for gnome_vfs_create_symbolic_link. * Bug 494500 – gnomecanvas.path_def_new() doesn't provide a way to build a closed path. * Ship with html docs * New WAF build system (to use it, do ./waf configure ./waf) The source tarball can be found here: http://download.gnome.org/sources/gnome-python/2.21/ Please file bug reports (bugs, missing APIs) here: http://bugzilla.gnome.org/enter_bug.cgi?product=gnome-python -- Gustavo J.

Re: [pygtk] ListStore iter vs. path
Caleb Marcus wrote: One question I have is, what's the difference between iters and paths? At a guess, I'd say that iters are likely to be more efficient, as they can hook directly into the underlying data structure, whereas a path requires some sort of lookup operation each time it's used. Whether this difference remains detectable amongst all the other overhead of Python/C interfacing is uncertain, though. I'd say just use whichever is more convenient for you, and only worry about performance if it becomes an issue. -- Greg ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
