Re: [wxVTK] VTK et wxWindows

[Mathieu M. <mat...@ki...>]

Salut Sébastien,

	[Switching to english, sorry ;)]

	Indeed compiling wxVTK on GNU/Linux can be a pain (to be polite). I did
wrote a quick note on the main site about that:

	http://wxvtk.sourceforge.net/
* wxVTK requires CMake 2.4 now. (CMake 2.4.3 suffers from bug #3582

	I guess this is not very explicit. But the issue is the following:

	The wxWidgets continue to refuse to expose an API I have been
requesting for a while now (more that 3 yrs), whereas the wxPython did
expose that same API (speak about consistency!). So the only way I found
was to figure out what GTK version the wxWidgets was built on. And the
heuristic to find it is very fragile (as you probably realized). I have
tried multiple option in the past, but this is too much work to maintain
(and I am not very active on this project anyway).

	Anyway the bottom line, is that you need somehow to figure out what is
the GTK used by your wxWidgets lib. I suspect you have an old library
that is still using gtk 1.2.x (this case is very poorly tested since my
main plateform uses gtk 2.x). By the way sending the full log of the
error is generally much self explanatory, please include if you want me
to comment.

	So to answer your question:

1. Yes definitely wx + VTK is know to work pretty well on Linux and
Win32. The people on Mac are complaining but Carbon support is getting
there.

2. I haven't played much with the new widgets architecture in VTK 5.1,
but the old widgets are working very nicely. I guess a lot of people on
this ML could also share there comment on the respsonsiveness of wx +
VTK when doing interaction. In the old days, wxGTK had an issue that
would cause a rerender (very bad for volume rendering) when moving the
mouse, I believe this is fixed in gtk2.x.

Please CC the ML, it makes my life much easier :) Thanks,
Mathieu
