only a quick idea ....
you could do that in combination with powerpro
[url=http://www.windowspowerpro.com]http://www.windowspowerpro.com[/url]
the idea is to call a script witch triggers the related action on a window (class or exe).
in powerpro you can set up a commandlist which is starting on filedialogs,
the commandlist could set a global variable
in strokeit -> run powerpro.exe .strokeit_proxy("up")
the ppro script name -> strokeit_proxy.powerpro
gesture = arg(1)
if (actwin == "filedialog") do
if(gesture == "up" ) do
win.debug("i gonna perform something for up now")
elseif (gesture == "down")
win.debug("i gonna perform something for up now")
endif
endif
i will publish an article about strokeit and powerpro on my site (soon)
