objoval.java

用java编写的画图面板程序（有源代码）

package project.paint;

import java.awt.Graphics2D;
import java.awt.geom.Ellipse2D;

//椭圆类
class ObjOval extends ObjRectangle {
	public ObjOval() {
		super();
		type=BaseObject.OVAL;
	}
	public String toString() {
		String s="椭圆("+String.valueOf(getMinX())+","+String.valueOf(getMinY())+")";
		s+=" 宽: "+String.valueOf(getWidth())+", 高: "+String.valueOf(getHeight());
		if (filled)
			s+=", 填充";
		return s;
	}
	public void draw(Graphics2D g2d) {
		shape=new Ellipse2D.Float(getMinX(),getMinY(),getWidth(),getHeight());
		shape2=new Ellipse2D.Float(0,0,getWidth(),getHeight());
		doDraw(g2d,shape);
	}
}
