为什么琴盘不能和鼠标同时出现在屏幕上呢,请帮忙看一下哪里出错了 #include"graphics.h" #include"stdlib.h" #include"dos.h" #define LEFTPRESS 0xff01 #define LEFTCLICK 0xff10 #define LEFTDRAG 0xff19 #define MOUSEMOVE 0xff08 int MouseExist; int MouseButton; int MouseX; int MouseY; void MouseOn(void); void MouseOff(void); int leftPress(void); int Rightpress(void); void MouseGetXY(void); void Play(void); void Init(void); void main() {Init(); Play(); } void MouseOn(void) { _AX=0x01; geninterrupt(0x33); } void MouseSetXY(int x,int y) { _CX=x; _DX=y; _AX=0x04; geninterrupt(0x33); } int LeftPress(void) { _AX=0x03; geninterrupt(0x33); return(_BX&1); } intRightPress(void) { _AX=0x03; geninterrupt(0x33); return(_BX&2); } void MouseGetXY(void) { _AX=0x03; geninterrupt(0x33); MouseX=_CX; MouseY=_DX; } void Init(void) {int graphdriver=VGA; int graphmode=VGAHI; int i,j; initgraph(&graphdriver,&graphmode,""); cleardevice(); MouseSetXY(50,220); MouseX=50; MouseY=220; setbkcolor(0); setcolor(3); for(i=0;i<50;i+=7) {line(56+12*i,200,56+12*i,300); line(20+12*i,200,20+12*i,300); } rectangle(20,200,12*49+20,300); setfillstyle(SOLID_FILL,1);

} } }
