Accessing the GUI only from the GUI thread is (in my experience) a pretty common requirement. I'm currently using WinForms which requires that GUI elements be accessed from the thread that created them, and IIRC Java Swing has the same limitation.

That is a huge limitation - in my experience most large GUI programs do use threads to allow the GUI to be responsive during long-running tasks.

Re: [Tutor] PyGTK: is there a library for both Linux and Windows
on differences: The downloads include binaries, so there have to be distinct files for Linux and Windoze. If you download the same versions, there shouldn't be any noticeable differences, with one big exception: multithreading and PyGTK don't mix well on Windows. Your application might run perfectly (and look correct) on Linux, but in Windoze it's a mess. You can find workarounds, but I haven't come across one that looked reliable. If you have Python 2.6 or higher, you can use the multiprocessing module (also available separately for earlier versions) to emulate threads with processes, which will relieve the problem, but make it a little harder for your threads (processes) to communicate with each other.

Re: [Tutor] PyGTK: is there a library for both Linux and Windows
The version of GTK for windows I like to use is at http://gladewin32.sourceforge.net/, but it is rather out of date. It's main advantage is everything is bundled up in a nice installer. You can also get it from the main site at ftp://ftp.gtk.org/pub/gtk, but you have to grab several files and install manually. I've never tried to figure out which ones, but I expect it wouldn't be hard. You could check the dependencies of the PyGTK shared objects, i.e. with http://www.dependencywalker.com/ You could also just get a more current, but still bundled up runtime from Pidgin (http://www.pidgin.im/), and install glade separately, as its only a single file. Note that you'll need to get PyGTK from the gnome site http://ftp.gnome.org/pub/gnome/binaries/win32/. Get PyGTK, PyObject, and PyCairo. Yes, glade is awesome. You'll need to learn how to hook the signals into your code. There are a lot of tutorials out there, but the ones I used are at the Linux Journal site: http://www.linuxjournal.com/article/6586 http://www.linuxjournal.com/article/7421 http://www.linuxjournal.com/article/4702 There's a bit of a caveat. You will find in most cases that the system Python and GTK (or numpy, PIL, etc) that your distribution provides is lagging somewhat behind what you can easily install on a Windows box, since there's aren't so many interdependencies. I'm just now starting to playing around with ArchLinux to see if I can get aruond this.

Glade is pretty useful for most people. I don't personally use it because I find that, personally, I spend more time looking up how to adjust something in Glade than just write the code myself. I guess if I were trying to write some large project or had a great desire to learn Glade, I'd find it useful. I know some people prefer it - I guess it should come down to this line of questioning: If you make a webpage do you prefer Arachnophilia/Dreamweaver/WYSIWYG or vi/emacs/notepad? When you regularly program do you prefer IDLE/Codeblocks/Etc. or vi/emacs/notepad? If you lean towards the former, I would recommend Glade. If you lean towards the latter, I would recommend you try out Glade, but you may likely find simply coding in your favourite editor works better for you.

Re: [Tutor] [pygtk] key_press_event
Sandro,
That's exactly what I need.
Thanks,
John.

If you don't return True, default callback will be called that insert
the 'a'.
I have something like this:
def digits_check_input_cb(self, widget, event):
"""prevents the possibility of inputting wrong chars"""
## fixme: missing comma, and cut&paste
key = gtk.gdk.keyval_name (event.keyval)
ONLYDIGITS="([0-9.,]|BackSpace|Left|Right|F1|period|Tab|Up|Down)"
if not re.match (ONLYDIGITS, key):
return True
Not sure whether this is the best way thought...
