Add Touch Screen Support for QT/Embedded

With the rapid development of embedded technology, embedded devices have been widely integrated into people's work and life. In order to improve the efficiency of interaction with embedded devices, research on embedded GUI for exchanging information with users has become a focus of study. This paper introduces the Linux 2.4 kernel based driver of s3c2410 touch-screen and the working mechanism of Qt/Embedded mouse device interface. Also, base on the similarity between the operation style of the touch screen with that of the mouse, this paper rewrites the mouse interface of Qt/Embedded linuxtp and realizes the QT/Embedded touch-screen support.
