[vtkusers] Mouse wheel events not working under Win32?

[Charles Boivin]

Hi Mathieu, thanks for your reply.

In response to your questions:

a) Yes, the mouse wheel works fine in other windows apps. In fact, it
even works in the vtk debug window

b) There are no WM_MOUSEWHEEL messages being passed to
vtkWin32RenderWindowInteractor::vtkHandleMessage2()

c) This is from a MFC app. In fact, it is from the VTK MFC SDI sample
application that I have modified a bit. Mind you, this is the SDI
application from version 4.4. Would the one from the CVS version pass
all the mouse events? I am definitely NOT a MFC guru, so I am not sure
how I should go about this.

Thank you for your reply.

Charles,

	- Does your mouse wheel works in any other Windoze apps ?

	- What happen in vtkHandleMessage2 
(vtkWin32RenderWindowInteractor.cxx), if you put a breakpoint / printf

stuff ?

	- Are you using a simple vtkRWI window ? Or is it within your
MFC app ? 
If so make sure you are passing all mouse events.
