There is also a few improvements I added to the code generator, which allowed the bonobo bindings to integrate better with the orbit bindings. The gnome-python release contains many new features (it is more than 50k larger than the last release). These include bindings for libbonobo, libbonoboui, libgnomeui, GConf, nautilus views and panel applets. The majority of this work was done by Johan Dahlin. The orbit-python package is a port of the stable orbit-python to ORBit2. This porting work was also done by Johan Dahlin.

[pygtk] GCC with -ansi option
Hi, I'm having some trouble compiling PyGTK from CVS. I get errors like these: /gnome/head/INSTALL/include/glib-2.0/glib/gmessages.h:108: warning: invalid character in macro parameter name The remedy seems to be removing the '-ansi' flag from the CFLAGS attribute. AKAIK the '...' in macro definitions is a GCC specific feature, therefore setting '-ansi' will error on those statements. Note that I did not configure GLib with the --enable-ansi option. I noticed this flag is explicitly set in configure.in (line 129). It should not be set if GLib is not compiled with ansi-compliance.

[pygtk] Freeing GObjects in Python
Hi, I'm using PyGTK (2.0) to do the graphical representation in a UML modeling tool (http://gaphor.sourceforge.net). I have created a small demo setup in a test program like this: + Model node + Package + Actor (data element) + UseCase (data element) + Diagram The diagram holds a DiaCanvas canvas inside, with two canvas items: one referencing the actor and one to the use case. Here comes my problem: If I remove all references to the data structure, no objects seem to be freed (at least the objects in the canvas are not freed). is it possible to wrap the canvas is such a way that it can be freed using the garbage collector? I noticed that the PyGObject has the HAVE_GC flag set. As it is now, the canvas object will only free itself if an explicit del diagram.canvas is done. It looks like the wrapper will not free the object, even if it holds only one reference... What can I do about this?

[pygtk] Patch: GtkTreeModel and refenecing objects
Hi,
I've created a patch that adds a 'leak_references' property to the
GenericTreeModel. Turning this feature off (default is on, the old
behaviour) will always decrement the refcount on PyObjects. This will
prevent memory/refcnt leaks from happening. The Model should ensure that
objects which are user as iterator are not destroyed before the iterator
is destroyed.
This sounds a bit silly, but there are no other way, unless we get to
know when a iterator is being removed...
Regards,
Arjan

[pygtk] threading issue...
Short Question: is there any way for the current thread to know that it doesn't have to call gtk.threads_enter() Long Question: I've got a function that can be called either by the thread responsible for gtk.mainloop() (call it the 'original' thread) or an 'outsider' thread that was spun off. The function makes a call that eventually gets down to some gtk stuff, so... therein lies the dilemma. My understanding is that the 'outsider' thread needs to call gtk.threads_enter() to ensure no collisions. The 'original' thread, however will cause a deadlock if it calls gtk.threads_enter(). I want them to both use the same function: def EventSelectedPlayer(self): self.debug( event: selected player id: + \ str(self.selectedPlayer.GetID()) ) #gtk.threads_enter() self.gameView.EventSelectedPlayer( self.selectedPlayer ) #gtk.threads_leave() So: has anyone done anything like this before? What is the strategy? Do I only call gtk.threads_enter() conditionally on whether the thread already owns the lock? If so, how do I find out Thanks for any help, sjbrown signature.asc Description: This is a digitally signed message part

http://www.async.com.br/faq/pygtk/index.py?req=all Hi there, I've added about 20 questions (75% or so with answers) and updated the old ones. Most stuff has been pulled from the mailing list, so you might see some verbatim stuff there. If you don't want me to cite your name, or if I forgot to add it somewhere and you want credit, let me know. There are a couple of XXX: comments. Most of these I know but was too tired to test and get a definitive answer now. If anybody knows an answer and wants to send it in, either ask for the password or send in the change through email and i'll do it. Hopefully we'll start getting things in, and docs will be less patchy (as most stuff that comes to the list is a FAQ anyway, this might make list traffic go down somewhat :-).
