在半透明的框架/面板/組件上重新油漆。我試圖在OSX上用Java創(chuàng)建一個(gè)半透明窗口，并添加一個(gè)JLabel敬它。這，這個(gè)JLabel每一秒都要改變它的文字.。然而，組件沒(méi)有很好地重新繪制。我怎樣才能解決這個(gè)問(wèn)題？我找到了這些 文章但我想不出怎么解決這個(gè)問(wèn)題。如果可能，請(qǐng)粘貼修復(fù)源代碼，這是我的：import javax.swing.JFrame;import javax.swing.JPanel;import javax.swing.JLabel;import java.awt.Color;import java.awt.Font;
import java.util.Timer;import java.util.TimerTask;public class Translucent {
public static void main( String [] args ) {
JFrame frame = new JFrame();
frame.setBackground( new Color( 0.0f,0.0f,0.0f,0.3f));
final JLabel label = new JLabel("Hola");
label.setFont( new Font( label.getFont().getFamily(), Font.PLAIN, 46 ) );
label.setForeground( Color.white );
frame.add( label );
frame.pack();
frame.setLocationRelativeTo( null );
frame.setVisible( true );
Timer timer = new Timer();
timer.schedule( new TimerTask(){
int i = 0;
public void run() {
label.setText("Hola "+ i++ );
}
}, 0, 1000 );
} }
