JProgressBar文本溢出

本文介绍了JProgressBar文本溢出的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我的程序在JProgressBar中写入文本.问题是文本比JProgressBar的宽度还要宽.

My program writes text in a JProgressBar. The problem is the text is wider than the JProgressBar's width.

我已经更改了JProgressBar的高度，以便能够在两行上写文本，但是我不想更改宽度.

I have already changed the JProgressBar's height to be able to write the text on two lines but I don't want to the change the width.

如果文本太宽，如何更改JProgressBar的溢出以使文本返回到下一行?

How to change the JProgressBar's overflow to make the text going back to the next line if it is too wide?

我希望这足够清楚:)

这就是我想要的:

谢谢

@mKorbel回复后，结果如下:

After @mKorbel reply the result looks like this:

标签工作得很好，但是为什么要剥离这些标签?

The label works quite fine but why those strips?

我的代码:

// Construct progress bar
JProgressBar progressBar = new JProgressBar(0, 100);
// Set progressBar color
progressBar.setForeground(new Color(0,176,80));

// Edit progress bar height
Dimension prefSize = progressBar.getPreferredSize();
prefSize.height = 50;
progressBar.setPreferredSize(prefSize);

// Set the layout
progressBar.setLayout(new BorderLayout(5, 5));

// Set progress bar value
progressBar.setValue(38);

// Construct the label
JLabel progressLabel = new JLabel("<html>I have already changed the JProgressBar's height to be able to write the text on two lines but I don't want to the change the width.</html>");
// Set alignment
progressLabel.setHorizontalAlignment(JLabel.CENTER);
progressLabel.setVerticalAlignment(JLabel.CENTER);

// Set the borders
progressLabel.setBorder(new EmptyBorder(15, 15, 15, 15));

// Change the font
font = progressLabel.getFont();
font = font.deriveFont(Font.BOLD, 12);
progressLabel.setFont(font);

// Add label to the progress bar
progressBar.add(progressLabel, BorderLayout.CENTER);

// Add progress bar to the frame
frame.add(progressBar);

推荐答案

  • 您能否提供一些有关如何执行此操作的代码? ---> JLayer& @aterai的JProgressBar ，有关更多想法，请参阅他的博客，对于Java6，您可以使用JXLayer

    • could you provide some code on how to do this? --- > JLayer & JProgressBar by @aterai, for more ideas see his blog, for Java6 you can to use JXLayer

      或使用GlassPane具有非常相似的逻辑

      or with very similair logics by using GlassPane

      一些笔记

      • 应使用GBC代替NullLayout

      • should be used GBC instead of NullLayout

      添加图标或透明背景可以变得更好

      can be nicer with added Icon or transparent background

      (通过将LayoutManager添加到JLabel)，可以放置一堆JComponent，其效果与JPanel相同

      (by add LayoutManager to JLabel) there can be placed bunch of JComponents with the same effect as for JPanel

      例如

      import java.awt.Container;
import java.awt.Dimension;
import java.awt.FlowLayout;
import java.awt.GridBagConstraints;
import java.awt.event.ComponentAdapter;
import java.awt.event.ComponentEvent;
import javax.swing.JButton;
import javax.swing.JCheckBox;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JProgressBar;
import javax.swing.JRadioButton;
import javax.swing.UIManager;
//https://stackoverflow.com/questions/14560680/jprogressbar-low-values-will-not-be-displayed
public class ProgressSample {

    private JFrame frame = new JFrame("GlassPane instead of JLayer");
    private JLabel label;
    private GridBagConstraints gbc = new GridBagConstraints();
    private JProgressBar progressSeven;

    public ProgressSample() {
        frame.setLayout(new FlowLayout());
        frame.add(new JButton("test"));
        frame.add(new JCheckBox("test"));
        frame.add(new JRadioButton("test"));
        // Nothing is displayed if value is lover that 6
        JProgressBar progressSix = new JProgressBar(0, 100);
        progressSix.setValue(2);
        frame.add(progressSix);
        // but this works value is higher that 6
        progressSeven = new JProgressBar(0, 100);
        progressSeven.addComponentListener(new ComponentAdapter() {
            @Override
            public void componentMoved(ComponentEvent e) {
                label.setBounds(
                        (int) progressSeven.getBounds().getX(),
                        (int) progressSeven.getBounds().getY(),
                        label.getPreferredSize().width,
                        label.getPreferredSize().height);
            }
        });
        progressSeven.setValue(7);
        frame.add(progressSeven);
        label = new JLabel();
        label.setText("<html> Concurency Issues in Swing<br>"
                + " never to use Thread.sleep(int) <br>"
                + " durring EDT, simple to freeze GUI </html>");
        label.setPreferredSize(new Dimension(label.getPreferredSize().width, label.getPreferredSize().height));
        Container glassPane = (Container) frame.getRootPane().getGlassPane();
        glassPane.setVisible(true);
        glassPane.setLayout(null);
        glassPane.add(label, gbc);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        try {
            UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
        } catch (Exception e) {
            e.printStackTrace();
        }
        ProgressSample dialogTest = new ProgressSample();
    }
}

      和

      • 结果是将JProgressBar用作Container，放在正确的LayoutManager位置，并在JLabel之前覆盖JProgressBar

        • result is to use JProgressBar as Container, put there proper LayoutManager, overlay JProgressBar by JLabel

          • 增强功能，可将EmptyBorder设置为JLabel，例如label.setBorder(new EmptyBorder(15, 15, 15, 15));
          • enhancements, to set EmptyBorder for JLabel, e.g. label.setBorder(new EmptyBorder(15, 15, 15, 15));

          EDIT2(图标也可以是半透明的，可以覆盖JProgressBar)

          EDIT2 (Icon is, can be semi_transparent too, can overlay JProgressBar)

          代码可能类似于

          import java.awt.BorderLayout;
import java.awt.Dimension;
import java.awt.EventQueue;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JProgressBar;
import javax.swing.UIManager;
import javax.swing.border.EmptyBorder;

public class JProgressBarWithJLabel {

    private JFrame frame = new JFrame("JLabel in JProgressBar");
    private JLabel label;
    private JProgressBar progressSeven;

    public JProgressBarWithJLabel() {
        progressSeven = new JProgressBar(0, 100){
            @Override
            public Dimension getPreferredSize() {
                return new Dimension(300, 60);
            }
        };
        progressSeven.setValue(38);
        progressSeven.setLayout(new BorderLayout(5, 5));
        label = new JLabel();
        label.setHorizontalTextPosition(JLabel.CENTER);
        label.setVerticalTextPosition(JLabel.CENTER);
        label.setBorder(new EmptyBorder(15, 15, 15, 15));
        label.setText("<html>I have already changed the JProgressBar's height "
                + "to be able to write the text on two lines but I don't want "
                + "to the change the width.</html>");
        progressSeven.add(label, BorderLayout.CENTER);
        frame.add(progressSeven);
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String[] args) {
        try {
            for (UIManager.LookAndFeelInfo laf : UIManager.getInstalledLookAndFeels()) {
                if ("Nimbus".equals(laf.getName())) {
                    UIManager.setLookAndFeel(laf.getClassName());
                }
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                new JProgressBarWithJLabel();
            }
        });
    }
}

          WindowsClassicLookAndFeel的默认剥离(图标不是半透明的)

          default stripping for WindowsClassicLookAndFeel (Icon isn't semi_transparent)
