This example illustrates the problem. Select with your cursor keys
one of the entries in the middle of the list and press your delete
key. The item will be deleted and the next one will be automatically
selected. But if you press your down key the second element of the
list will be selected, ignoring the previous selection.

[pygtk] How do I abort a drag and drop?
I presume that I must catch the drag_begin signal and process it in such a way that the drag is interrupted. The function processing the signal seems to be documented as returning void, I can put return true|false but it doesn't have any effect on the drag operation. I've read the documentation of gdk_drag_abort() and tried to mimic it with pygtk, but it doesn't have any effect: def begin_drag(self, widget, context): context.drag_abort(long(0)) return 0 The function gets called, but the drag operation still goes on.

Re: [pygtk] Python binding of Pango should accept 'None' as anargument.
On 2003-04-02, Alif Wahid [EMAIL PROTECTED] wrote: [...] You see in Pango some functions are passed a NULL pointer to specify default behaviour. This doesn't seem to be the case in the Python binding, in other words we can't pass a None type object to achieve the same feat without generating unnecessary exceptions about the wrong type. In particular the method get_metrics(...) of a pango.Font derivative doesn't accept the None object and spews up a TypeError exception instead. On the other hand in the C API passing a NULL pointer to the same function simply means to do the default thing (that is to load metrics for the entire font, not language dependent). So as you can see Python binding should follow the same sort of Pango API conventions. [...] Maybe this case should be handled with something similar to the following recipe? http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/68205 It createas a Null class which avoids rasing TypeError and such (or so the recipe claims). The idea would be to differentiate None, which could be passed in from a previous function if something went wrong, and this should still be treated like a mistake. Null instead is like saying see, I wan't you to use NULL in the C code, and I'm showing that I didn't pass you None by accident. -- Please don't send me private copies of your public answers.

[pygtk] Translating PyGTK programs
Hi. Last time I checked the faq said something strange about not using gettext, using intl, then using again gettext :-? So I took an example from the pygtk directory and started hacking it until I managed to get it working with python's gettext module. The example is attached. Can somebody check if this is ok? I see that the FAQ has been updated, but looks like it focuses on the C part of gettext, and this smaller example might be easier to understand for newbies. Feel free to put it in the faq or some cvs directory. I was also wondering if you need help with PyGTK's web page, I do web maintaining for other free software. I'm not in the side of graphic design and such (I browse with elinks), I focus on having content updated. translating_interfaces.tar.bz2 Description: Binary data

[pygtk] Want to start with pygtk, but automake gets in the way
Hi. I'm a fresh new programmer who would like to get started learning pygtk for gtk 2.0 under gnu/linux. So I checked out the cvs code of pygtk and made sure to get all the required developement debian packages (libpango1.0-dev, libgtk2.0-dev, etc). Missing is the automake package, since debian includes 1.5, but autogen.sh looks for version 1.6. No problem, I installed the source version and now autogen.sh continues, but drops lot's of warnings: I am going to run ./configure with no arguments - if you wish to pass any to it, please specify them on the ./autogen.sh command line. WARNING: aclocal's directory is /usr/local/share/aclocal, but... no file /usr/local/share/aclocal/glib-2.0.m4 You may see fatal macro warnings below. If these files are installed in /some/dir, set the ACLOCAL_FLAGS environment variable to -I /some/dir, or install /usr/local/share/aclocal/glib-2.0.m4. WARNING: aclocal's directory is /usr/local/share/aclocal, but... no file /usr/local/share/aclocal/gtk-2.0.m4 ...blah blah blah... Now, I have these files, but they are installed in another place: [gregorio:37] [~/cvs/libs/pygtk]$ locate glib-2.0.m4 /usr/share/aclocal/glib-2.0.m4 [gregorio:38] [~/cvs/libs/pygtk]$ locate gtk-2.0.m4 /usr/share/aclocal/gtk-2.0.m4 [gregorio:39] [~/cvs/libs/pygtk]$ locate gettext.m4 /home/gregorio/instalacion_manual/mutt-1.4/m4/gettext.m4 /mnt/g/cvs/progs/source-navigator-support/gettext.m4 /usr/share/aclocal/gettext.m4 /usr/share/aclocal/glib-gettext.m4 So, looks like automake is looking for the .m4 files only in the /usr/local/share/aclocal/, when all the packages are in another place. I expected to force automake look there, but without success: the strange info manual doesn't seem to tell anything about path configuration (unless it's about where to put installed files by the generated makefiles). I guess I will have to make some symlinks, but before I do so, does somebody know if there's a way to tell automake where to look for .m4 files? ___ pygtk mailing list [EMAIL PROTECTED] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://www.async.com.br/faq/pygtk/
