graph creators don't work

Marek — Wed, 07 May 2008 18:38:28 -0000

hi!
in version 0.99c no graph crator works. i investigsted this a bit and i found that this is because the newly created graph is assumed to be euclidian, but the edges are added before the coordinates of vertices are set.

so i set G.euclidian=0 in each graph creator in GraphCreator.py (just after G=Graph()) and this helped.

but the bug exists.

new graph - AttributeError

Marek — Wed, 03 Oct 2007 10:17:28 -0000

Hi!
When i try to run window for drawing graphs i obtain the following error:

Exception in Tkinter callback
Traceback (most recent call last):
File "/usr/lib/python2.4/lib-tk/Tkinter.py", line 1345, in __call__
return self.func(*args)

File "/usr/lib/gato/Gred.py", line 378, in makeMenuBar
if self.windowingsystem == 'aqua':
AttributeError: SAGraphEditorToplevel instance has no attribute 'windowingsystem'

I'm running on Gentoo Linux, Python 2.4 and gato-0.99. Version 0.98p of gato worked fine for me.

whitespace lines in mailcap cause crash

Anonymous — Thu, 07 Sep 2006 17:51:11 -0000

Hi,

I have a blank line in my .mailcap file. Gato crashed
like this:

dalexander@c163-206:~/packages/Gato$ python Gato.py
Traceback (most recent call last):

No filenames in GatoIcons.py

Leonardo Santagada — Thu, 26 May 2005 00:28:54 -0000

The file apears to be autogenerated by another perl
file. The perl script didn't come with the distribution
and the filenames are empty. I am using the package
Gato-0.98O.tar.gz. I have an old version somewhere
else, maybe it got this file. ( I also would like to
talk to someone about the debugger that use the
undocumented internal python module, if someone wants
to talk just send me a mail)

EPS export size

David Grant — Thu, 24 Feb 2005 20:29:30 -0000

I have no idea why, but one of my graphs is getting
cut-off at the bottom during EPS export.

Please see attachment. I am using Windows, I haven't
tried Linux to see if the same problem occurs. I'll try
later tonight on my Linux machine perhaps, perhaps it's
just ghostscript's fault...

Infinite Loops cannot be aborted

Alexander Schliep — Sat, 21 Sep 2002 13:50:44 -0000

FindPath.alg on graph with negative cycle produces
infinite loop which cannot be aborted by clicking on stop.

Determining Screensize

Alexander Schliep — Fri, 22 Mar 2002 12:10:47 -0000

Sometimes determining the correct screen size
for producing automatic window layout fails with
some window managers (like fvwm).

Make Gato end-of-line-agnostic

Alexander Schliep — Thu, 21 Mar 2002 12:58:18 -0000

Check and fix the end-of-line problems with prologs and
algorithms.
Things should be compatible on all plattforms.
