Abstract: This article start from the architectural of the Linux system, analyze the structure of
ESCUT GUI. Combining development of embedded Linux in Fiscal Cash Register, this article
discusses the whole design of the ESCUT GUI by illustrating the design of Window, and discuss mouse message, keyboard message, window management and so on, with the example of windows of the system. Transplantation of GUI is explained by an example. Finally, it summarize the characteristics of the GUI system, and show its application occasions.
