abs_pointer

Description

Interface implemented by tablet devices. Used by consoles to send touchpad events to the controller. The set_state function is called when something changes in the console. The coordinates are given as scaled absolute scaled values, where (0, 0) is the upper-left corner and (0xffff, 0xffff) is the lower-right corner.

} abs_pointer_buttons_t;
