怎样处理坐标？？

Question

你可以用textbox,label等控件显示数字

Answer 1

坐標??妳點擊叫"1"的按鈕  就在顯示的地方的String改變一下啊

Answer 2

我写了一个类，画七段数码的，但是不知怎样调用，而且关键我的坐标不会处理，因为老师要求，把计算器放大，显示数码的面板也跟着放大。我头都大了，就是不会啊，我实在不知怎么处理坐标，所以把头一个坐标设为（50，50）。
class SevenDigitalDemo 
{
        public  int x=50;
        public  int y=50;
        public void UpDemoPainting(Graphics g)//UpDemoPainting
{
Polygon p1=new Polygon();
p1.addPoint(x,y);
p1.addPoint(x+20,y+20);
p1.addPoint(x+80,y+20);
p1.addPoint(x+100,y);
g.drawPolygon(p1);
g.setColor(Color.red);
g.fillPolygon(p1);

}

public void RightDemoPainting(Graphics g)//RightDemoPainting
{
Polygon p2=new Polygon();
p2.addPoint(x+83,y+23);
p2.addPoint(x+83,y+83);
p2.addPoint(x+96,y+96);
p2.addPoint(x+103,y+89);
p2.addPoint(x+103,y+3);
g.setColor(Color.red);

g.fillPolygon(p2);
}

p3.addPoint(x+4,y+96);
p3.addPoint(x+17,y+83);
p3.addPoint(x+17,y+23);
g.setColor(Color.red);
g.drawPolygon(p3);
g.fillPolygon(p3);
}


public void  MidDemoPainting(Graphics g)//MidDemoPainting
{
Polygon p4=new Polygon();
p4.addPoint(x+20,y+86);
p4.addPoint(x+80,y+86);
p4.addPoint(x+92,y+98);
p4.addPoint(x+80,y+106);
p4.addPoint(x+20,y+106);
p4.addPoint(x+8,y+98);
g.drawPolygon(p4);
g.fillPolygon(p4);
}

public  void LeftdownDemoPainting(Graphics g)//LeftdownDemoPainting
{
Polygon p5=new Polygon();
p5.addPoint(x+4,y+100);
p5.addPoint(x+17,y+109);
p5.addPoint(x+17,y+169);
p5.addPoint(x-3,y+189);
p5.addPoint(x-3,y+107);
g.drawPolygon(p5);
g.fillPolygon(p5);
}

public void RightdownDemoPainting(Graphics g)//RightdownDemoPainting
{
Polygon p6=new Polygon();
p6.addPoint(x+96,y+100);
p6.addPoint(x+103,y+107);
p6.addPoint(x+103,y+189);  
p6.addPoint(x+83,y+169);
p6.addPoint(x+83,y+109);
g.drawPolygon(p6);
g.fillPolygon(p6);
}

public void DownDemoPainting(Graphics g)//DownDemoPainting
{
Polygon p7=new Polygon();
p7.addPoint(x+20,y+172);
p7.addPoint(x+80,y+172);
p7.addPoint(x+100,y+192);
p7.addPoint(x,y+192);
g.drawPolygon(p7);
g.fillPolygon(p7);
}
}
老师的意思是七段数码一定要画出来，按下1的时候，就显示七段数码中的1
，按下2，就显示2。

即不同时间显示8的不同部位而已/

这很困难吗，每次resize面板时记下原来的大小，用新的大小跟旧的比值，再乘于你那些坐标就行了把
