Because I am lazy/overbook I think there are still some patch in the
wxVTK CVS that are not in any release unfortunately.
That's weird, I thought that the timer thingy bug only appear after
VTK 5.0. But I did it from the top of my head.

ok

Simply that VTK mimic typical behavior of such device. If you have
ever played games, you have two typical behavior either pointing the
joystick down will make you move down, and stop as soon as you
release. Or like in a plane you have to point down, and then point up
to stop the movement
(This is pretty badly explain, but I did my best, sorry. Hopefully you
did get the big picture).

Not that I know of. Anyone on the ML to comment on that ? I think most
people using wxVTK are from academic background.
Furthermore Kitware is now officially supporting Qt and KWWidget so
for a comapny I think it make more sense to use those toolkits (IMHO).

Please send patch ;)
As far as I remember the bug was non-trivial, or require patching wx
itself. I was hoping that wx 2.8.1 would include a fix (this already
happen in the past on the 2.4.x branch)/ wx people are not extremely
serious people, when dealing with backward compatiblity.

Noone complains, because wxVTK is bug free :-P

Re: [wxVTK] [vtkusers] Anyone using wxVTK wxVTKRenderWindowInteractor wxWidgets VTK class?

[Sander N. <nie...@st...>]

At our company we are currently using the wxVTK package.

We use wxWidgets/VTK for the development of an ESA-funded open-source  
application called VISAN (part of the BEAT toolbox: http:// 
www.stcorp.nl/beat).
The current public available version of VISAN uses some hand-crafted  
wxVTK bridge with Python bindings, but internally we have now moved  
to wxPython 2.8, VTK 5 and wxVTK (since we moved more stuff to C++  
and wanted to include support for Gtk2 and Mac OS X Carbon). We are  
now able to create working binaries for Windows, Linux (Gtk2), and  
Mac OS X (Carbon). A new release of VISAN with these changes is due  
in September.

In order to get things to work we had to patch the wxVTK sources.  
Attached you will find the patch that we used.
The primary change that we made in order to get wxVTK to work with  
wxWidgets 2.8 was to move back to using wxGLCanvas again (i.e. remove  
the '#if (!wxCHECK_VERSION(2, 8, 0))').

The timer warning is something we haven't seen. But we are using our  
own interactor styles for most of our visualisations anyway, so that  
may be the reason.

Hi Sander,

  Wow ! That is fantastic, thank you so much for the patch !
  Can I ask just one quick question, about the OnKeyUp/OnChar thingy.
Did you notice that capital letter were being passed ?

  Patch will be merged tonight.


Thanks again,
-Mathieu

Hi Mathieu,

In our implementation we don't have capitalization issues (for the  
OnChar).
However, mind that we are currently only testing this against  
wxPython 2.8 and VTK 5.
So capitalization issues may be present with older wxWidgets/VTK  
versions.

>   Patch will be merged tonight.

Be careful here. Since we haven't tested against older wxWidgets/VTK  
versions you may break backward compatibility by including this patch.

Best regards,
Sander

Sorry about that...
