If you've anything that can be shared about how you took the long(er) route, please consider doing so. Cairo is basically immediate mode. Which means you need to redraw everything in the exposed area every time. A canvas is retained mode. Meaning you build some objects that know how to redraw themselves every time they are exposed, with support for placing them and possibly overlapping them and only drawing what's on top. If your drawing is simple enough then it's easier to just use Cairo; the more objects you throw onto the screen, the more sense it makes to use a full canvas to subdivide the work so you don't end up with a gigantic unmaintainable draw method. I needed a canvas that would work well with the old versions of libraries on RHEL 5 and not have license problems, and couldn't find one (GnomeCanvas didn't let me rescale things well, GooCanvas didn't work well for me for some reason I've forgotten and was also a pain to build, the one from OLPC was GPL licensed), so I wrote my own. Basically inherits from DrawingArea and does Cairo calls in the draw methods. The canvas is only 850 lines of Python, but it's the kind of fiddly lower-level GUI code that's a pain to write. There are classes for rectangles, lines with arrows on the ends of them (which require some trig to draw correctly), SVG images (rsvg module), text (pango and pangocairo). A general-purpose canvas library would have more stuff, but that's all I needed. Performance is fine for a small number of displayed objects but doesn't scale well to hundreds of objects. I'd like to obsolete this code when we can switch to RHEL 6. I highly recommend reusing one of the existing canvases rather than writing your own if at all possible. -- David Riptondrip...@ripton.net ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

It found the old one instead of the one you just installed. I am sure there is something simple I am doing wrong, but my Linux-Fu is a little rusty. Can anyone point me in the right direction for getting Python 2.5 to find and use gobject? I see two paths to victory. One is finding the magic configure option to tell configure exactly which glib to use. This will probably be something short and obvious-in-hindsight like --glib=/usr/local/lib/libglib-2.0.so, but since configure --help doesn't actually tell you all the options, it may require digging around. The other is installing an older version of pygobject, which is compatible with glib 2.12. Then finding the platform glib will be fine. The Python libraries for the platform Python 2.4 (/usr/lib/python2.4) and for your Python 2.5 (probably /usr/local/lib/python2.5) are completely independent. You have to install everything again for 2.5. But if you don't actually need features or bugfixes from the newer version of a Python library, it's easier to use the same old version that CentOS uses, because you know all its C library prerequisities are already installed. -- David Riptondrip...@ripton.net ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

what layout (directories and classes) do you use for a
pygtk project? I am programming since several years, but I am not
used to event based programming like pygtk.
The pygtk tutorial suggest this:
{{{
class HelloWorld:
def __init__(self):
self.window = gtk.Window(gtk.WINDOW_TOPLEVEL)
...
self.show()
def main(self):
gtk.main()
if __name__ == __main__:
hello = HelloWorld()
hello.main()
}}}
If you start other dialogs from HelloWorld, which depend on data
stored in the main
object, do you pass it around, or do you store it in a global variable
at module level?
I pass it around.
I don't use globals in non-trivial code that also has classes, because
once you've gone to the bother to use classes then instance variables
are about as easy to use as globals, and cleaner.
So If I have widget A that depends on widgets B and C, I add B and C as
instance variables inside A. When possible I set them exactly once in
A.__init__, to simplify lifespan issues and make the code easier to
read.
Note that the HelloWorld class above encapsulates a gtk.Window rather
than inheriting from gtk.Window. I think this is usually right, because
you often want code in your class that's not part of the parent widget's
mission, so has-a makes more sense than is-a. And it's easier with
Glade to have not-widget classes that encapsulate stock widget classes,
than to have custom-widget classes, because that way you don't have to
write custom loading code. I only subclass gtk widgets when I actually
need a custom widget that does its own drawing, which usually means a
gtk.DrawingArea subclass.
As far as packages / directories go, my personal preference is to keep
it as simple as possible until it actually needs to be complex. That
means that I start with one directory and put all the files there, use
sibling imports rather than package imports, run the code straight out
of the source tree rather than installing it, etc. When the project
actually gets big enough that one directory gets unwieldy, then I move
files into subdirectories. When it's ready to deliver to endusers, then
I make an installer and do proper packages. IMO it's easier that way,
and modern version control systems don't punish moving files around like
CVS did.

Right after this thread is launch, I periodically execute a function from the GTK lop, using gobject.timeout_add(). In this function, I read some variables of the external thread to refresh the GUI. The user can also interact with the GUI during the shooting process, to pause/stop it. All works fine on my PC (running linux), but I experience several problems on maemo. For example, some part of the GUI are not correctly refreshed the first time I launch the shooting process. If I stop it, and retry, all works fine. Another issue is that I can send user action at wrong moments. I think this a related to the lower speed execution of the application, showing me some wrong-codeed things in my app. So I need to add some robust inter-threads sync mecanisms, to ensure I can't trigger actions at the wrong place. I tried to use the Event object from the standard threading module, but it does not work under maemo (while it works fine on the PC) :o( If threading.Event doesn't work on maemo, I worry about whether the other basic locking primitives are broken too. Try running test_thread.py and test_threading.py from the Python source tree. If basic locks are broken then threads are completely unsafe, and you'll need to either fix them or use a different concurrency model. So, what other mecanism should I use to sync my threads? Is there a GTK-based macanism? Assuming threading.Lock works on maemo, I suggest Queue.Queue, from the Python standard library. The idea is that you don't share mutable objects across threads. Instead, you pass safe messages composed of tuples of immutable value objects (strings, ints, etc.) across queues. Then your threads can't corrupt each other's mutable data because they can't even see each other's mutable data. And you won't get deadlocks because you're not using lots of locks, just one per queue, which is inside proven library code. And you can't read data at a bad time (like in between updating x and y of the camera's position coordinates) because the other thread knows when to safely put its data onto the queue. In your case I think you'd want two queues, one carrying commands from the GUI thread to the external thread (e.g. (move_camera, 3, 4, 5)) and one carrying status the other way (e.g. (flashed, Bulb3, 1227370225.247529)). And then each side has a loop that periodically does a non-blocking read from the appropriate queue and takes the appropriate action if it finds something there. -- David Ripton[EMAIL PROTECTED] ___ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/

Anyway, the version constants I found are documented here: http://www.pygtk.org/docs/pygtk/gtk-constants.html#gtk-version-constants And the function I found is documented here: http://www.pygtk.org/docs/pygtk/gtk-functions.html#function-gtk--check-version -- David Ripton[EMAIL PROTECTED] ___ 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/

Re: [pygtk] calling a program from a program

Is the child program actually exiting when you close its window, or just
hiding the window? os.system will block the parent program until the
child program actually exits.
If you want the parent program to freeze until the child exits, then
resume, then you probably just need to make the child actually terminate
(with sys.exit) when you close its main window.
If you want the parent to stay responsive while the child runs, then you
probably want to launch the child program in the background (see the
docs for the subprocess module). Another option would be creating a
second thread in the main program and spawning the child program from
it, so the main thread can keep processing events.

Re: [pygtk] trying to launch a pygame app from within my gtk app

Does anyone have experience launching a executeable on a windows box
from within there GTK app?
I made a GUI app with pyGTK that I want to be able to launch a game I've
downloaded from the pygame website when a button is clicked. I was able
to do this on a linux box since the file was a .py file, but I'm not
sure how to do it on a windows box since the game's file is an
executeable for windows. On
linux I did this:
import os
olddir = os.getcwd() #to keep a reference to the old
directory to switch games later
os.chdir('spacinVaders-0.1') #switch to the game's directory
os.spawnlp(os.P_NOWAIT, 'pythonw', 'pythonw', 'play.py')
and it would launch fine can someone help me with this??
but i can't get it to work if i do something like
os.spawnlp(os.P_NOWAIT, 'pythonw', 'pythonw', 'play.exe')
Can you only run python scripts from a python program? Or am I missing
something?
os.spawnlp doesn't work on Windows. You need to use one of the
other spawn variants. See http://docs.python.org/lib/os-process.html
And you probably need to run pythonw.exe, not just pythonw. (And
maybe with a full path, if your Python directory is not in the PATH.)

Timeoutsock is a commonly used Python module that allows TCP sockets to have a timeout on various operations. http://www.steffensiebert.de/soft/python/timeoutsocket.py Note that the version of the socket module included in Python 2.3+ includes the ability to use timeouts on both http (like timeoutsocket) and https (unlike timeoutsocket) connections. So, unless you're stuck on Python 2.2, there's no real need for timeoutsocket anymore. -- David Ripton[EMAIL PROTECTED] ___ 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/
