代码如下
public void paintComponent( Graphics g )
{
super.paintComponent( g );
Shape current;
for ( int i = 0; i < shapes.size(); i++ ) {
current = ( Shape ) shapes.elementAt( i );
current.draw( g );
}
}
public void paintComponent( Graphics g )
{
super.paintComponent( g );
Shape current;
for ( int i = 0; i < shapes.size(); i++ ) {
current = ( Shape ) shapes.elementAt( i );
current.draw( g );
}
}
public void paintComponent( Graphics g ) //重写组件
{
super.paintComponent( g ); //调用父类的构造方法
Shape current; //申明current属于Shape类
for ( int i = 0; i < shapes.size(); i++ ) { //从零到shape的大小进行循环
current = ( Shape ) shapes.elementAt( i ); //将shapes转换成Shape类型，并将该组件加入到current中
current.draw( g ); //画出current
}
}
总体来说：就是重写paint方法。
