I've successfully compiled wxVTK and have integrated it into my application. The trouble I am having is that if I use wxGLCanvas as the sub-class I can't get double buffering to work. If I use wxWindow double buffering works, but the window only refreshes in response to VTK events and not wx events. Any hints? |

Which wx events would you like it to respond to?

I had a similar issue that I solved by changing the default
constructor of the class wxVTKRenderWindowInteractor to:
wxGLCanvas((wxWindow*)(NULL), wxID_ANY, wxDefaultPosition,
wxDefaultSize, 0, wxT("glcanvas"), attributes)
where attributes is defined as:
int attributes[5] = {
WX_GL_DOUBLEBUFFER,
WX_GL_RGBA,
WX_GL_DEPTH_SIZE,
16,
0
};
which enables double buffering for wxGLCanvas.
My two cents.
Pierre.

Is it something that was reported before (possibly the bug tracker)
that I forgot to merge ?
thx

Not that I know. I ran into this bug a few months ago by testing softwares on recent nvidia graphic cards, where I experienced lots of flickering. It turns out that by explicitly setting double buffering to On solved the problem. As I am not an openGL expert, I was pretty OK with this workaround. There are some discussions about this issue that you may find useful: http://www.nabble.com/OpenGL,-wxWidgets-and-Ubuntu-7.10-td16047290.html The trick of activating the double buffering works well on any system I tried (windows, linux - various distributions - and macosx). Sorry for not reporting it to the list but things went a bit crazy around here these days (and months). Hope this helps, Pierre.

I updated to the latest wxVTK via CVS, which includes the wxvtk_attributes array in wxGLCanvas's constructor. If I call wxGLCanvas::SwapBuffers() after the line in wxVTKRenderWindowInteractor::OnPaint() which calls Render(), my screen starts out as black, which I believe is the undrawn buffer. So I think wxGLCanvas is being correctly initialized, but that the buffer swapping isn't working correctly inside Render(). I'm not sure, this is my best guess at the moment. Anyway, this still isn't working for me. I'm using NVIDIA's glx and get the following version info from glxinfo: server glx vendor string: NVIDIA Corporation server glx version string: 1.4 On Thu, Feb 26, 2009 at 10:10 AM, Pierre Fillard <pie...@gm...> wrote: > Not that I know.
