[Visualpython-users] vpython and wxpython integration

[Emanuele G. <ema...@gm...>]

I am developing a small multiplatform application for data visualisation.
Could someone point me to a simple example on how to integrate a wxpython
GUI with vpython 3d visualisation?
Thank you.

[Visualpython-users] vpython and wxpython integration

[Emanuele G. <ema...@gm...>]

Thanks Stef for your reply, but my application has to be multiplatform.
I think that your solution is for Windows only.

I don't need wxpython in particular, but the vpython controls are not enough
for me.
I would like to show a tree of the displayed objects, so that the user can
select them and edit their properties. This could be in another window,
thought I would prefer it integrated in the 3dview window.

Can someone suggest a tool to obtain such an effect?
Thanks once more.

This is probably a naive notion, but this sounds like a somewhat 
straight-forward VPython program, in which you show a tree of the 
displayed objects (probably the nodes of the tree are miniature versions 
of those objects). I assume by tree you mean that objects would be 
grouped under frames. I have the vague notion that someone once built 
some kind of visual tree structure in VPython....? Or that there exist 
Python modules for creating/analyzing tree structures?

I also draw everyone's attention to the new component of Visual 5, 
filedialog.py, which is an example of pure platform-independent Python 
code which provides basic file dialog services. It also works with 
Visual 3. Maybe there are elements there of the additional controls you 
seek.

Now the Qt license will change,
it might be interesting to take a look at Qt,
seems to have a dock feature for windows and linux ( don't know for MAC).

cheers,

look here,

http://mientki.ruhosting.nl/data_www/pylab_works/pw_vpython_docking.html

but it will only work for VPython-3.
In VPython-5 there are "features" that will crash the application,
and from Bruce I understood that these "features"  will not be removed 
on a short term.

cheers,
Stef

Well you gave the answer (in which the "features" were mentioned)  off list,
the problem was docking VPython-5, after moving or resizing the window,
VPython crashed.

cheers,
Stef

It has nothing to do wxPython.
And as I suspected that you didn't use wxPython,
I attached a little autoit-executable (which is written directly on the 
windows APIs), so you reproduce the bug without wxPython.
The fact that this autoit program shows the same problem,
also proves that it's not wxPython to blame.

cheers,
Stef

I guess I didn't explain adequately. The only way I can have a fighting 
chance at debugging a problem is if I'm given a maximally simple program 
Visual-only program that shows the problem. If the problem is embedded 
inside a very complex program, or inside an executable, or depends on an 
environment such as wxPython, there's not much I can do with the report, 
especially because I'm under the gun to finish a major revision of a 
physics textbook.

But the wonderful news is that CL, who knows the wxPython environment, 
has dug into two bugs and apparently fixed them at the C++ level. As 
soon as I have a chance to incorporate his fixes I'll post new installers.

Re: [Visualpython-users] vpython and wxpython integration

[Bruce S. <Bru...@nc...>]

I know about the limitation of Visual 5 that on the Mac it's not 
possible to invoke Tk, due to conflicts over who is the primary thread, 
but what's the nature of the issue with wxpython on Windows? I don't 
recall saying anything about features of Visual 5 that would prevent 
doing something with wxpython. (I wouldn't be surprised if there were 
problems, given the architecture of Visual, it's just that I don't know 
anything about wxpython, nor what aspects of Visual 5 would cause problems.)

[Bruce S. <Bru...@nc...>]

No, the issue there was that there isn't any way for me to debug that 
very complex program, since I know nothing about wxpython. In the case 
of Mac Tk, the issue is known: Carbon wants to be the primary thread. I 
don't know what property of Visual 5 interferes with trying to embed it 
in wxpython on Windows.
