[Visualpython-users] GtkGLExt vs GtkGLArea

[Arthur <ajs...@op...>]

Something to consider as to VPython's future development. The quote
below is, I believe, by the gtkglarea developer.

http://www.student.oulu.fi/~jlof/gtkglarea/


"""

GtkGLArea
OpenGL widget for GTK+

GtkGLArea source can be found from cvs.gnome.org

Another OpenGL solution for GTK+: GtkGLExt is an interface to use OpenGL
on any GTK+ widget.

I recommend that you select GtkGLExt over GtkGLArea since GtkGLExt is
actively maintained. (It is probably technically superior too.)

We too had picked up on this. We'll be keeping this in mind in a major
overhaul that Jonathan Brandmeyer is beginning to replace CXX by Boost, as
per your suggestion a while ago.

I'll take this opportunity to say that it might seem like we haven't been
keeping up on various initiatives and suggestions recently, but progress is
being made. Jonathan has created a "configure"-based installer for
Unix/Linux systems. It works on Linux, but we're still working on issues for
Mac OSX.

Re: [Visualpython-users] GtkGLExt vs GtkGLArea

I started some skeleton code using gtkglextmm a while ago.  As a new
feature, it has been on hold while we overhaul the Unix installation
tools.  If you want to look at what has been started you can look at the
files xgl2.cpp and xgl2.h in the CVS cvisual module.  We will not be
including the code in any distributions until it has been fully tested. 
You won't even get it to compile without some other patches to the
source tree.  If you want it, ask and you shall recieve.

Even after we have full support for GtkGLext, we will probably keep the
GtkGLarea code around for compatability with the slow movers (eg,
Debian).

 I happen to be installing visual on a fresh Mandrake 9.1  Not exactly
smooth, but I'm sure I'll get there.
What's the status of the "configure" installer?  Ready for prime time? beta?
need a tester?

Re: [Visualpython-users] GtkGLExt vs GtkGLArea

[Jonathan B. <jbr...@ea...>]

Beta.  We are still working out kinks on OSX.  If you want to try on
Mandrake, that would be a good data point for us.  We know that it works
on Debian Woody and Red Hat 8.0 (with one tweek).

[Visualpython-users] more on idlefork problems

[Gary P. <pa...@in...>]

I have news to report re: my problems with idlefork.

Again, I know that I seem to be the only one having problems, but maybe
someday someone else will ...

Recall that under Win98 idlefork froze my system requiring reboot.

I've upgraded to XP.   Now idlefork will run and everything seems fine, but
when I close idlefork an error is generated ... can't read locatation
0x000000028 or something.

if I start idlefork from the command line (python idle.py) it starts
normally.
if I start it using python -v idle.py it spews an enormous number of
messages, most of which go by too fast to read. THere is one that I can
sort-of read because it is repeated about 50 times.  It contains the
filename "CallTips.py", but that's about all I can grab.  Then it seems to
go into shut-down mode.  The final messages are

----------------------------------
[...]
# cleanup sys
# cleanup __builtin__
PyThreadState_Clear:  warning: thread still has a frame
# cleanup ints:  14 unfreed ints in 3 out of 6 blocks
# cleanup floats:  4 unfreed floats in 1 out of 1 block

[here there is a looooonng pause during which the cpu roars along at 100%]

Font Tahoma 8 still in cache.
TkFontPkgFree:  all fonts should have been freed already

This application has requested the Runtime to terminate it in an unusual
way.
Please contact the application's support team for more information
--------------------------------------

What's the DOS way of redirecting all that output into a file?
If I start regular idle using "python -v idle.py"  it starts just fine
(spewing many fewers messages than idlefork), and quits just fine.
Ringing any bells?

I just noticed that a new version of idlefork is available.  I haven't tried
that new one yet.
