Re: Detecting mouse events in the SQL grid

Hi Guillaume,

No, I don't know if it is dealt with at the window level. I also thought that this could be the issue, i.e. that the event is intercepted and handled somewhere else, but I could not find out where that might be. Any advice?

Also, one (probably basic) thing is unclear to me: If I handle this mouse event (or most other input events), do I then prevent the event from being managed by its default handler, which maybe I need to invoke from my event handler to make sure no default behavior is missed?

Thanks,
KariK

Are you sure it's not already dealt with at the window level?
