I'm trying to work around this bug where old glade files do
not load with libglade-2.4.1
http://bugzilla.gnome.org/show_bug.cgi?id=160586
One workaround is to ship two sets of glade files and
choose which one to load based on the libglade version.
Any ideas on how to programmatically determine libglade version?
Or any other workarounds?
Stephen.
Here is how I did it so far on a gentoo system. Your method for
checking the installed version will be different for a different
distribution. ver_match() pads the version strings to three digits per
so 2.4.1 would become 002.004.001-r000. -r000 being the install
ebuild revision number. Then checks for a match in the ranges specified.
portagelib is our programs interface to the imported portage modules
(gentoo's package management system). I will most likely need to
modify the code to choose which version to use if both ranges are
installed. In gentoo I recommended that libglade-2.4.1 be masked due to
bugs and incompatibility with existing apps. I also recommended it be
slotted differently than current libglade-2 versions (which could mean
there may be up to 3 simultaneous libglade versions installed on the
system).
def check_glade():
determine the libglade version installed
and return the correct glade file to use
porthole_gladefile = porthole.glade
# determine glade version
versions = portagelib.get_installed(gnome-base/libglade)
if versions:
dprint(versions)
old, new = ver_match(versions, [2.0.1,2.4.0-r99],
[2.4.1,2.99.99])
if old:
porthole_gladefile = porthole.glade
elif new:
porthole_gladefile = porthole-new.glade
else:
dprint(MAINWINDOW: No version list returned for libglade)
return None
dprint(MAINWINDOW: __init__(); glade file = %s %porthole_gladefile)
return porthole_gladefile
