Hi,

some recent change in trunk (didn’t find which) broke the color list generator in r.colors:

Traceback (most recent call last):
File “/home/neteler/software/grass71/dist.x86_64-unknown-
linux-gnu/etc/gui/wxpython/gui_core/widgets.py”, line 1294,
in OnDrawItem

r.x + bitmap.GetWidth() + 10,
AttributeError

r.x + bitmap.GetWidth() + 10,
AttributeError

Using:
g.version -g
version=7.1.svn
date=2014
revision=59549M
build_date=2014-04-02
build_platform=x86_64-unknown-linux-gnu

A fix would be appreciated. In relbranch70 is seems to work fine.

thanks
Markus

hmm, it works for me. But I remember, it happened to me some time ago but
then it started to work again. It looks like it can't find the thumbnails.
I fixed it to display at least the name of the color table when it can't
find the picture for whatever reason.

after a "make distclean" the problem disappeared and the color
pictures are shown.

well, I didn't fix the original problem of missing thumbnails, I just fix
the behavior so that the drop down shows at least the names of colortables
when it can't find the thumbnails. I don't know if just distclean always
helps, there might be some compilation problem because I know that Vasek
was complaining about it too and he probably did make distclean... Just to
keep that on mind if it happens again.
