actor picking with vtkWin32RenderWindowInteractor

[Patric.Weis at mycrona.de]

Hi Agris!

Maybe the following can help:

To 1)
   Did you try the mfc sample in the ..\sample directory, loading e.g.
weldedSpheres.vtk? Does this work? It's no problem with Win NT.

To 2)
   The easiest way is an explicit call of
vtkWin32RenderWindowInteractor::OnChar() in your menu command function,
e.g.

      m_pIren->OnChar(this->GetSafeHwnd(), int('p'), 1, 0);

Hi!

I am writing a MFC doc/view program on a w2k computer and encountered
difficulties with actor picking.
To set up the renderer, window and interactor I am using the following code

void CMadelungView::PrepareForUnitCellPlot()
{
....
 m_pRenderer = vtkRenderer::New();
 m_pRenWin = vtkWin32OpenGLRenderWindow::New();
 HWND hwnd = this->GetSafeHwnd();
  m_pRenWin->AddRenderer(m_pRenderer);
  m_pRenWin->SetParentId(hwnd);

 m_pIren = vtkWin32RenderWindowInteractor::New();
 m_pIren->SetRenderWindow(m_pRenWin);
......
}

1) I can rotate and zoom actors with mouse, but keyboard commands (like "p"
- picking, "w" - wireframe, etc.) doesn't work. Is there something missing
in my code?
2) I would like also to start picking of actors with a menu command instead
of "p". Is there an easy way how to do it?




Thanks in advance!
