这里有人使用合金外观吗?我在使用抗锯齿和JTextComponents时遇到一个奇怪的错误。默认情况下,Alloy根本不使用抗锯齿功能,因此我必须通过创建自己的UI类来强制使用抗锯齿功能。在大多数情况下,这可以正常工作,但是某些字符会对消除锯齿造成严重破坏。

例如,如果将Alloy设置为外观,并且我将一些希伯来语文本插入JTextComponent中,例如:

奇怪的是,我什至没有扩展AlloyTextPaneUI,而是通过BasicTextPaneUI进行抗锯齿,因此我对合金出现在图片中的位置感到困惑(其他外观似乎很好)。

我很难追踪这个错误...有人遇到同样的问题吗?

这是一个演示问题的简短示例:

import com.incors.plaf.alloy.AlloyLookAndFeel;
import com.incors.plaf.alloy.themes.glass.GlassTheme;

import javax.swing.*;
import javax.swing.plaf.ComponentUI;
import javax.swing.plaf.basic.BasicTextPaneUI;
import javax.swing.text.BadLocationException;
import javax.swing.text.StyledDocument;
import java.awt.*;

public class Scrap {

    static {
        // NOTE: You need a license code for Alloy!
        AlloyLookAndFeel.setProperty("alloy.licenseCode", "your license here");

        UIManager.put("TextPaneUI", MyTextPaneUI.class.getName());

        try {
            UIManager.setLookAndFeel(new AlloyLookAndFeel(new GlassTheme()));
        } catch (UnsupportedLookAndFeelException e) {
            e.printStackTrace();
        }

        // With system Look and Feel everything works just fine...
//      try {
//          UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
//      } catch (ClassNotFoundException e) {
//          e.printStackTrace();

//          e.printStackTrace();
//      } catch (UnsupportedLookAndFeelException e) {
//          e.printStackTrace();

    }

    public static void main(final String args[]) {
        JTextPane text = new JTextPane();

        text.setFont(new Font("Monospaced", Font.PLAIN, 14));

        StyledDocument doc = text.getStyledDocument();

        try {

            doc.insertString(doc.getLength(), "Here's some regular text. Nice and smooth with anti-aliasing.\n\n", null);

            doc.insertString(doc.getLength(), "Here's some more text Blaa Blaa Blaaa. Lorem ipsum... now try to uncomment the Hebrew text.\n\n", null);

            // Try to uncomment this line and the anti-aliasing breaks for the whole JTextPane
//          doc.insertString(doc.getLength(), "שלום, מה שלומך שמי הוא האקזידן\n\n", null);

            // Here's another strange glyph that breaks the anti-aliasing
//          doc.insertString(doc.getLength(), "ಠ", null);

        } catch (BadLocationException e) {
            e.printStackTrace();
        }

        JFrame frame = new JFrame();

        JScrollPane scroll = new JScrollPane();
        scroll.setViewportView(text);
        scroll.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER);

        frame.add(scroll, BorderLayout.CENTER);
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        frame.setSize(600, 300);
        frame.setLocationRelativeTo(null);
        frame.setVisible(true);
    }

    public static class MyTextPaneUI extends BasicTextPaneUI {

        @Override
        protected void paintSafely(Graphics g) {
            Graphics2D g2 = (Graphics2D) g;
            g2.setRenderingHint(
                            RenderingHints.KEY_TEXT_ANTIALIASING,
                            RenderingHints.VALUE_TEXT_ANTIALIAS_LCD_HRGB);
            super.paintSafely(g);
        }

        public static ComponentUI createUI(JComponent c) {
            return new MyTextPaneUI();
        }
    }
}

最佳答案

经过一些非常令人沮丧的实验后,我将其修复。.我仍然不确定是什么导致了它,但是这是我修复它的方法。合金中的UIDefaults中显然有一个键丢失/损坏(我不知道是哪个键)。因此,我将所有默认设置(从初始外观和感觉)添加到Alloy属性。这是一种快速而肮脏的解决方案(我唯一的问题是菜单变得不透明),但足以满足我的需求。也许其他人发现它也有帮助。

AlloyLookAndFeel laf = new AlloyLookAndFeel(theme) {
    @Override
    public UIDefaults getDefaults() {
        UIDefaults defs = new UIDefaults();

        defs.putAll(UIManager.getLookAndFeelDefaults());

        initClassDefaults(defs);
        initSystemColorDefaults(defs);
        initComponentDefaults(defs);

        defs.put("Menu.opaque", true);

        return defs;
    }
};
