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

[Shang M. <smu...@gm...>]

Kerry,

I would guess it's a behavior of Windows or wxWidgets on Windows, or purely 
wxWidges issue. I guess so because I recently met similar issue using 
another wx lib called wxMathPlot. I had several plots(a window derived from 
wxScrolledWindow) aligned in a row in a same window, and once I used mouse 
wheel in one plot, all later mouse wheel events are sent to that plot, even 
if I clicked in another plot.

However, I think SetFocus() might fix both your and my mouse wheel problems. 
And I think I don't have middle button up/down issues.
