I'm moving this from Racket Users to Racket Developers instead, I hope that is correct.

First, is https://github.com/racket/gui.git the correct repo to dig in? Second, are .../gui-lib/mred/private/[common|gtk|win32|cocoa]/ the right directories to look in? A very quick look seems to indicate that .../common/event.rkt defines the windowing events (e.g. mouse-event%, key-event%, etc), and that actual instances of the events are created in .../gtk/window.rkt, .../win32/window.rkt, and .../cocoa/window.rkt. I also see ffi-stuff in the respective window.rkt files, am I right to assume this is where the gui events from the respective underlying windowing system gets translated into Racket events, and that it would be here similar code for touch events should be added? Again, I have only briefly looked at this, so I just wish to make sure I am looking in the right place. I will then continue to read docs and code, and try not to ask too many stupid questions... :-) Cheers, /johan -- Johan Liseborn -- You received this message because you are subscribed to the Google Groups "Racket Developers" group.
