[pygtk] right-justified text in Entry widget?
Hi, I've tried vainly to come up with something that gives me an Entry widget where the text inside is right-justified. entry.get_layout().set_alignment(pango.ALIGN_RIGHT) did not work. A .context_changed() thereafter doesn't help, too. Either nobody but me wants this feature, or I'm missing something very obvious, as nobody seems to have asked this before (searched with Google and the mailing list archives).

[pygtk] PyGtk/C extension - segfault
Hi,
a few days ago, I've got a great help on gtk<->pygtk objects wrapping.
Thanks a lot.
Now, I have the library but the application crashes on segfault. I've been
thinking it is problem of mine or problem of Python but PyGtk seems to have
own part of this too.
My program looks like:
/* python setup */
...
Py_Initialize();
...
/* module setup */
initcavfs(); // init C extension - module cavfs
initpywrap(); // init C extension - module pywrap
/* While cavfs does just Py_InitModule("cavfs", cavfs_methods); */
Now, on init_gobject() or "import gtk" I get a segfault which ALWAYS leads
to a stack trace similar to:
#0 0x4d8b07f3 in strrchr () from /lib/libc.so.6
#1 in cavfs_methods()
#2 in init_gobject()
loading /usr/lib/python2.2/site-packages/gtk-2.0/libgobject.so
...
Please, note that cavfs_methods is a variable of type PyMethodDef. There's
no such method and it isn't referenced elsewhere! Compiled library contains
cavfs_methods pointer in a data part not code part.
Does anyone faced the same problem? Or can you image where's the root of my
problem? Why does cavfs_methods get called?
Thanks a lot, Tobbi

Thanks for your reply Yes, I use ItemFactory, I have only imitate the example in the pygtk-tutorial. What do you mean by "keep a reference" ? How can I do that ?

[pygtk] button causes pop-up menu (?)
Hello, I've been hitting my head for quite some time now on how to make a button cause a menu appear. At least, that's what I think I want. What I actually is something like evolution's contact editor, where entering someone's birthday actually just consists of pushing a button, which causes a calendar widget to appear under it. I've gotten as far as having the menu item display a menu with the calendar in it, but since I think the menu doesn't expect the calendar widget it's useless. Plus, it's "selected" by the menu, which just makes it look ugly. I hope this description isn't too confusing. Any help would be appreciated. Please CC to me.

The library gobject.so contains a global variable PyTypeObject
*PyGObject_Type.
This leads to conflict and segfault. I'm not good enough to explain why, but
that's enough for me :)

I didn't, that's true, but my backtrace in gdb is complete so I assume pygtk
already contains a debug info.
After sitting many hours on the problem I found it is caused by a DEFINITION
of a global variable!
Strange, huh?
Precisely:
module cavfsmodule.c defines:
static PyMethodDef cavfs_methods[] = {
...
};
module gwrapper.c defines:
PyTypeObject *PyGObject_Type = NULL;
Now, the segfault occurs, gdb says that cavfs_methods is called although it
is referenced just in the initialization method.
If I change gwrapper.c to: "static PyTypeObject *PyGObject_Type = NULL;" the
segfault new happens.
Finally, this seems to be a compilation problem, isn't it?
Actually, I'm happy I found a way to avoid the problem. If someone has
similar experience, please, let me know.
