我已經爲我的JDialog寫了一個動畫，但是如果我在JButton的偵聽器中執行它，它可以工作，但是在我的構造器編號中。我嘗試使用線程和計時器，它不工作。從底部動畫移動JDialog
我的代碼：
TestTheDialog.java
import java.awt.event.ActionListener;
import javax.swing.JFrame;
import javax.swing.JButton;
import java.awt.event.WindowAdapter;
import java.awt.event.WindowEvent;
import java.awt.event.ActionEvent;
public class TestTheDialog implements ActionListener {
JFrame mainFrame = null;
JButton myButton = null;
public TestTheDialog() {
mainFrame = new JFrame("TestTheDialog Tester");
mainFrame.addWindowListener(new WindowAdapter() {
public void windowClosing(WindowEvent e) {System.exit(0);}
});
myButton = new JButton("Test the dialog!");
myButton.addActionListener(this);
mainFrame.setLocationRelativeTo(null);
mainFrame.getContentPane().add(myButton);
mainFrame.pack();
mainFrame.setVisible(true);
}
public void actionPerformed(ActionEvent e) {
if(myButton == e.getSource()) {
System.err.println("Opening dialog.");
CustomDialogMessage myDialog = new CustomDialogMessage(mainFrame, true, "+33679149407","azertyuiopqsdfghjklmwxcvbnazertyuiopqsdfghjklmwxcvbn");
System.err.println("After opening dialog.");
if(myDialog.getAnswer()) {
System.err.println("The answer stored in CustomDialog is 'true' (i.e. user clicked yes button.)");
}
else {
System.err.println("The answer stored in CustomDialog is 'false' (i.e. user clicked no button.)");
}
}
}
public static void main(String argv[]) {
TestTheDialog tester = new TestTheDialog();
}
}
CustomDialogMessage.java：

myPanel = new JPanel();
myPanel.setPreferredSize(new Dimension(dialogWidth, dialogHeight));
myPanel.setBackground(new Color(1,0,0,0));
myPanel.setLayout(null);
getContentPane().add(myPanel);
JLabel header = new JLabel(textHeader);
FontMetrics fm = header.getFontMetrics(header.getFont());
fm.stringWidth("You got a new message !");
header.setBounds((dialogWidth- fm.stringWidth(textHeader))/2, 0, 200, 30);
myPanel.add(header);
closeButton = new JButton("Close");

你永遠不會調用'動畫（）'任何地方。 – supersam654
請詳細解釋一下，關於__您究竟計劃做什麼？__，__究竟發生了什麼？__和__究竟是什麼意思？__ –
如果您將動畫（）放在JButton的偵聽器上，我們可以看到JDialog的移動一直到屏幕右側的角落。但我想要構造函數上的這個動畫，但如果我在構造函數上調用animation（）它不起作用。當我創建我的JDialog時，我希望它出現在右下角並向上移動。有點像MSN通知。 – g3r4n
