matplotlib-devel Mailing List for matplotlib

Hello
While working on my multi-figure-backend I found an error in DialogLineprops
If you transform the example
matplotlib/examples/user_interfaces/lineprops_dialog_gtk.py
to use the Gtk3 backend you get with a nice error
Traceback (most recent call last):
 File "/home/fariza/workspace/matplotlib/examples/user_interfaces/lineprops_dialog_gtk.py",
line 21, in <module>
 dlg = DialogLineprops([l1,l2])
 File "/home/fariza/workspace/matplotlib/lib/matplotlib/backends/backend_gtk3.py",
line 711, in __init__
 import Gtk.glade
ImportError: No module named Gtk.glade
The current implementation of backend_gtk3 requires libglade for DialogLineprops
but if I am not wrong libglade is being replaced by Gtk.Builder.
If the solution is to move to Gtk.Builder
The transition involves creating a new glade file and reworking
DialogLineprops to use the new api.
Just for my information,
When was this DialogLineprops in Gtk3 introduced?
I just want to know if I can rework it to accept figures instead of
lines, to be compatible with my multi-figure-backend.
Or if it has a large userbase and needs to be updated as it is.
Thanks
Federico

Wow -- setup_requires is new to me. It's worth a shot.

There is setup_requires, and from the documentation that I see, I wonder if
listing NumPy in both build_requires and install_requires invokes a special
handling to install setup requirements in the same place as install
requirements?

Unfortunately, this is a known bug in setuptools. It has no concept of 
"build time" dependencies, so it probably computed all of the 
dependencies correctly, but it doesn't install them in the correct order 
-- it just assumes that as long as everything gets installed it will 
work when it's finally run. This is the same problem that means even 
though matplotlib specifies numpy as a dependency, "pip install 
matplotlib" will not work unless numpy is already installed. This is a 
perennial problem, and apparently the setuptools guys spend very little 
time considering C extensions at all.

So, I was working from a completely fresh virtualenv, installing a package
that had a matplotlib dependency. As it happens to be, the dependencies in
this package lists matplotlib prior to numpy, so matplotlib got processed
first. For whatever reason, while processing matplotlib, it didn't seem to
think that it depended upon NumPy, but failed anyway when it couldn't find
it. See the following output:
