thanks eunmi! i've put it in svn, BUT with some changes. i've changes some Evas_Event_Touch_Type and Evas_Touch_Point_State enum names because they were not really consistent, CANCEL and CANCELLED, PRESSED, RELEASED (rest of evas uses DOWN/UP) docs were wrong too there. MOVE vs MOVED, and START normally comes with STOP, or BEGIN comes along with END. > Dear Enlightenment developers, > > Nice to meet you. > I'm Eunmi Lee, developing mobile web browser and working on WebKit EFL port. > I need new type of event for touch, so I've made patch to add > EVAS_CALLBACK_TOUCH event to the evas. > > I will explain history of this patch. > Currently, many web applications and sites use TouchEvent and they can do > everything(scrolling, zooming and so on) like native application using > TouchEvent.
