Re: [wxVTK] Middle Mouse Button And Scroll Wheel Events

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

I think I'm using wxVTK 1.30 (.cxx file is rev 1.30, .h file is rev 1.16).

I have discovered the cause of the middle mouse button not working - it was
my fault - the mouse's software configuration does not treat the middle
mouse button as a middle mouse button by default.  It was set to "zoom"
(whatever that is...), but I put it to "middle mouse button" and all is well
with the button events.

The scroll events, however - this is what I've learned:

The OnMouseWheel function in wxVTK is being called when I start the program
and move the scroll wheel.  I can zoom in and out just fine.  After clicking
on another control and then back on the wxVTK, the OnMouseWheel function is
never called, no matter what direction I scroll the mouse of what
combination of key presses and mouse clicks I try.

Mathieu, I did implement the bug fix, but since the function isn't being
called, it didn't help.  I do like the changes it made to the scroll wheel
functionality, though.  It seems that the "/ event.GetWheelDelta()" was
responsible for limiting the "zooming" capability.

Shang, I'll try the SetFocus() fix and report back...

Thanks for your help!
