LHL_GUICore file is the underlying abstraction function, because I did not get the book computer graphics point of view, so some functions relatively low efficiency, I have time to solve, I hope not tucao, thank you. LHL_NormalButton is a key part of the source code control. If you want the button to display text, then you need to call a function: void LHL_FontPutStringAt (unsigned short xPos, unsigned short yPos, char* ch, unsigned short Fontcolor, unsigned short Bkcolor, unsigned char Type)
