欲每次我点击按钮“布顿”来执行该功能的actionPerformed跳过步骤
boutonPane.Panel2(H,....)这是应该显示H圆。所以我想2然后3然后4,然后5 ...圈子。
问题是它没有显示数字4的步骤。我看到该功能在控制台中调用,但它在屏幕上确实是2,(按下按钮)3,(按下按钮)5,(按下按钮)9。我没有看到4.我没有看到6,7,8 ..你能告诉我什么是问题吗?下面是代码:
public class Window extends JFrame implements ActionListener {
int lg = 1000; int lrg = 700;
int h = 2;
Panel b = new Panel();
private JButton btn = new JButton("Start");
JButton bouton = new JButton();
private JPanel container = new JPanel();
public Window(){
this.setTitle("Animation");
this.setSize(300, 300);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.setLocationRelativeTo(null);
container.setBackground(Color.white);
container.setLayout(new BorderLayout());
JPanel top = new JPanel();
btn.addActionListener(this);
top.add(btn);
container.add(top);
this.setContentPane(container);
this.setVisible(true);
}
public void Window2()
{
System.out.println("windows2");
this.setTitle("ADHD");
this.setSize(lg, lrg);
this.setLocationRelativeTo(null);
bouton.addActionListener(this);
if(h<11)
{
Panel boutonPane = new Panel();
boutonPane.Panel2(h, Color.BLUE ,lg, lrg, this.getGraphics());
System.out.println("draw"+h);
boutonPane.add(bouton);
this.add(boutonPane);
this.setContentPane(boutonPane);
this.revalidate();
this.repaint();
}
this.setVisible(true);
}
public void actionPerformed(ActionEvent e)
{
if((JButton)e.getSource()==btn)
{
System.out.println("pressed0");
Window2();
}
if((JButton)e.getSource()==bouton)
{
h++;
System.out.println("pressed"+h);
Window2();
}
}
}
下面是一个Panel类:
public class Panel extends JPanel
{
int m;
int i=1;
int a=0, b=0, tremp=0;
Color cc;
int lgi, lrgi;
int [] ta;
int [] tb;
Graphics gi;
int u=0;
Panel()
{
}
public void Panel2(int n, Color c, int lg, int lrg, Graphics g){
m=n;
cc=c;
gi=g;
lgi=lg;
lrgi=lrg;
ta = new int [n]; ta[0]=0;
tb = new int [n]; tb[0]=0;
}
public void paintComponent(final Graphics gr){
gr.setColor(Color.red);
for(int it=0; it<m;it++)
{
ta[it]=100*it;
tb[it]=100*it;
gr.fillOval(ta[it],tb[it], 150, 150);
}
}
}
我希望现在编辑正确。有人有我的问题的答案吗? – user3460225
