Hack for Linux wxGrid mousewheel bug

[Ed Welch]

You may have noticed the mouse wheel scrolling does not work for the wxGrid under Linux.
Here is a simple, but effective work-around (add to your wxGrid-drived class):

Code: Select all

BEGIN_EVENT_TABLE(EzGrid, wxGrid)
#ifdef __WXGTK__
    EVT_MOUSEWHEEL(EzGrid::OnMouseWheel)
#endif
END_EVENT_TABLE()

#ifdef __WXGTK__
void EzGrid::OnMouseWheel( wxMouseEvent& event )
{
        int nWheelRotation = event.GetWheelRotation();
	int x, y;
	GetViewStart(&x, &y);
	if (nWheelRotation < 0) y+=5;
	else y -= 5;
	Scroll(x, y);
}
#endif

This might make a good patch to wxGrid I think...
