我目前正在使用Java的媒体播放器,利用VLCJ的力量,我正在实现均衡器调整窗口。在它们下面将有11个垂直滑块,带有JLabel,指示hZ频段和该频段的dB电平。但是,滑块与JLabel之间保持着巨大的差距。我试着仅将两个JLabel堆叠在一起,根本没有间隙。我的代码如下。 (返回均衡器的东西尚未实现。我只想在开始添加功能之前就可以使用基本的UI)
import java.awt.GridLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JSlider;
import uk.co.caprica.vlcj.player.Equalizer;
public class VideoEQFrame {
public VideoEQFrame() {
//constructor
}
public Equalizer show() {
JFrame frame = new JFrame("Effects");
JPanel panel = new JPanel();
JPanel sliders= new JPanel();
JPanel gainObjects = new JPanel(new GridLayout(2, 0, 2, 0));
JSlider gainS = new JSlider(JSlider.VERTICAL, -12, 12, 0);
gainS.setMajorTickSpacing(2);
gainS.setPaintTicks(true);
gainS.setToolTipText("Adjust the gain");
JLabel gainL = new JLabel("Text");
gainObjects.add(gainS);
gainObjects.add(gainL);
sliders.add(gainObjects);
panel.add(sliders);
frame.add(panel);
frame.setSize(new Dimension(600, 300));
//frame.setResizable(false);
frame.setVisible(true);
Equalizer eq = new Equalizer(0);
return eq;
}
}
您正在使用GridLayout
放置滑块和文本标签。这意味着它们将占据相同的高度。因此,由于滑块的高度较大,因此标签的高度也将调整为此高度。尝试像LayoutManager
这样使用另一个BorderLayout
,如下所示:
import java.awt.BorderLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JSlider;
public class VideoEQFrame {
public VideoEQFrame() {
//constructor
}
public void show() {
JFrame frame = new JFrame("Effects");
JPanel panel = new JPanel();
JPanel sliders= new JPanel();
JPanel gainObjects = new JPanel(new BorderLayout());
JSlider gainS = new JSlider(JSlider.VERTICAL, -12, 12, 0);
gainS.setMajorTickSpacing(2);
gainS.setPaintTicks(true);
gainS.setToolTipText("Adjust the gain");
JLabel gainL = new JLabel("Text");
gainObjects.add(gainS, BorderLayout.CENTER);
gainObjects.add(gainL, BorderLayout.PAGE_END);
sliders.add(gainObjects);
panel.add(sliders);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(panel);
frame.pack();
frame.setLocationRelativeTo(null);
//frame.setResizable(false);
frame.setVisible(true);
// Equalizer eq = new Equalizer(0);
// return eq;
}
public static void main(final String[] args) {
new VideoEQFrame().show();
}
}
