[wxVTK] Middle Mouse Button And Scroll Wheel Events

[Kerry L. <lo...@gm...>]

Hello All,

I've come across a couple of curious bugs that I can't seem to track down,
and they're both related to my middle mouse button.  My middle mouse button
up/down events don't fire.  I set a breakpoint at the
wxVTKRenderWindowInteractor OnButtonDown() function and both the right and
left mouse buttons cause the breakpoint to be reached, but I get nothing
from the middle button.  Is there something else I need to do to set this
up?

Also, I am having a similar problem with the scroll wheel.  When I first
start my app, I can use the scroll wheel just fine, but if I click on
another control, then click back into the RenderWindow, the scroll wheel no
longer functions.  Same deal with the breakpoints - the event handler is
never called.

Any ideas on these?  Has anyone else noticed this behavior?

Thanks for your help!
