如何制作JFrame動畫？

Question

我想知道是否有任何庫或其他東西可以像BUZZ一樣對JFrames進行動畫處理！ 如果沒有現有的庫可以執行yahoo Messenger中的動畫，那么執行該操作的可能算法是什么？

Answer 1

您可以為要處理的幀創建自己的Buzz方法。 查看下面給出的代碼。

編輯正如MadProgrammer和DavidKroukamp所建議的那樣，我已更改代碼以符合標准。 :)

import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.SwingUtilities;
import java.awt.BorderLayout;
import java.awt.Point;
import java.awt.event.ActionListener;
import java.awt.event.ActionEvent;

class BuzzFrame extends JFrame 
{
    private JButton buzz = new JButton("BUZZ ME!!");
    public BuzzFrame ()
    {
        super("BUZZ Frame!!");
    }
    public void prepareGUI()
    {
        buzz.addActionListener(new BuzzActionListener(this));
        setSize(300,200);
        getContentPane().add(buzz,BorderLayout.NORTH);
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }
    public static void main(String st[])
    {
        SwingUtilities.invokeLater ( new Runnable()
        {
            @Override
            public void run()
            {
                BuzzFrame bFrame = new BuzzFrame();
                bFrame.prepareGUI();
                bFrame.setVisible(true);
            }
        });
    }
}
class BuzzActionListener implements ActionListener
{
    private JFrame frame;
    private Point currLocation;
    private int iDisplaceXBy = 5;
    private int iDisplaceYBy = -10;
    public BuzzActionListener(JFrame frame)
    {
        this.frame = frame;
    }
    @Override
    public void actionPerformed(ActionEvent evt)
    {
        currLocation = frame.getLocationOnScreen();
        fireBuzzAction();
    }
    private void fireBuzzAction()
    {
        SwingUtilities.invokeLater ( new Runnable() 
        {
            @Override
            public void run()
            {
                Point position1 = new Point( currLocation.x + iDisplaceXBy , currLocation.y + iDisplaceYBy );
                Point position2 = new Point( currLocation.x - iDisplaceXBy , currLocation.y - iDisplaceYBy );
                for (int i = 0; i < 20 ; i++)
                {
                    frame.setLocation(position1);
                    frame.setLocation(position2);
                }
                frame.setLocation(currLocation);
            }
        });
    }
}

看一眼

• 時序框架
• 三叉戟
• 吐溫通用引擎

您將需要評估每一項，以確定哪種最能滿足您的需求

我用一個簡單的功能做到這一點：

 public void ZUMBIDO() { toFront(); new Thread(new Runnable() { int milisegundos = 50; int posiciones = 20; public void arriba() { Point pos = getLocation(); pos.translate(0, posiciones); setLocation(pos); } public void abajo() { Point pos = getLocation(); pos.translate(0, -posiciones); setLocation(pos); } public void derecha() { Point pos = getLocation(); pos.translate(posiciones, 0); setLocation(pos); } public void izquierda() { Point pos = getLocation(); pos.translate(-posiciones, 0); setLocation(pos); } public void proceso() { try { arriba(); Thread.sleep(milisegundos); derecha(); Thread.sleep(milisegundos); abajo(); Thread.sleep(milisegundos); izquierda(); Thread.sleep(milisegundos); } catch (InterruptedException ex) { Logger.getLogger(cliente.class.getName()).log(Level.SEVERE, null, ex); } } @Override public void run() { for (int i = 0; i <= 5; i++) { proceso(); } } }).start(); } 

您可以在下一個代碼中觀看它的運行，它是一個帶有回聲概念的簡單聊天。
