Question

如果我把内容类型设定为<代码>text/html的话,我可以把标题放在 Java中。我祝愿它们在内容类型为<条码>、文字/解释<>/条码>、缺省时结束。

这是我的样本方案的产出,这表明,当一个超文本编辑处理翻译时,这些线路确实占用了更多的空间:

形成框架的法典是:

import java.awt.BorderLayout;
import java.awt.Dimension;

import javax.swing.JFrame;
import javax.swing.JTextPane;
import javax.swing.text.StyleConstants;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.StyleSheet;

public class DemoSimplestGui extends JFrame  {
    private static final long serialVersionUID = 1L;

    private static final int WINDOW_WIDTH = 800;
    private static final int WINDOW_HEIGHT = 130;

    private static final String PLAIN_TEXT = "" +
        "This is some <b>plain text</b>
" +
        "separated by backslash-n characters
" +
        "There s no empty space between lines
" +
        "which is exactly what we need.";

    private static final String DIV_BASED_HTML_TEXT = "" +
        "<div>This is some <b>html text</b></div>" +
        "<div>that usses DIV tags.</div>" +
        "<div>There s too much blank space</div>" +
        "<div>and that sucks for my application</div>";

    private static final String PRE_BASED_HTML_TEXT = "" +
        "<pre>This is some <b>html text</b></pre>" +
        "<pre>that usses PRE tags</pre>" +
        "<pre>There s too much blank space grr</pre>" +
        "<pre>and that sucks for my application</pre>";

    public static void main(String[] args) {
        final DemoSimplestGui frame = new DemoSimplestGui();
        frame.setPreferredSize(new Dimension(WINDOW_WIDTH, WINDOW_HEIGHT));
        frame.setSize(frame.getPreferredSize());
        frame.setMinimumSize(new Dimension(WINDOW_WIDTH / 2, WINDOW_HEIGHT / 2));
        frame.init();
        frame.setVisible(true);
    }

    public void init() {
        setLayout(new BorderLayout(10, 10));
        add(createPlainTextPane(), BorderLayout.WEST);
        add(createDivBasedHtmlTextPane(), BorderLayout.CENTER);
        add(createPreBasedHtmlTextPane(), BorderLayout.EAST);
    }

    private JTextPane createPlainTextPane() {
        final JTextPane textPane = new JTextPane();
        textPane.setContentType("text/plain");
        StyleConstants.setFontFamily(textPane.getInputAttributes(), "Courier New");
        textPane.setText(PLAIN_TEXT);
        return textPane;
    }

    private JTextPane createDivBasedHtmlTextPane() {
        final JTextPane textPane = new JTextPane();
        textPane.setContentType("text/html");
        textPane.setEditorKit(configureHtmlEditorKit(textPane));
        textPane.setText(DIV_BASED_HTML_TEXT);
        return textPane;
    }

    private JTextPane createPreBasedHtmlTextPane() {
        final JTextPane textPane = new JTextPane();
        textPane.setContentType("text/html");
        textPane.setEditorKit(configureHtmlEditorKit(textPane));
        textPane.setText(PRE_BASED_HTML_TEXT);
        return textPane;
    }

    private HTMLEditorKit configureHtmlEditorKit(JTextPane textPane) {
        final HTMLEditorKit kit = (HTMLEditorKit) textPane.getEditorKit();
        final StyleSheet css = new StyleSheet();
        css.addRule("body { font-family: monospaced; margin-top: 0; margin-down: 0; line-height: 0; }");
        css.addRule("div, pre { margin-top: 0; margin-down: 0; line-height: 0; }");
        kit.setStyleSheet(css);
        return kit;
    }

}

我确实赞赏某些方面:D

Answer 1

平台可能取决于:

Answer 2

类似情况

StyledDocument doc= textPane.getStyledDocument();
MutableAttributeSet attr= new SimpleAttributeSet();
StyleConstants.setLineSpacing(attr, -0.2f); //NOTE: negative value.

就像你一样,看着窗户。 JDK/JRE的哪些版本正在使用?

Answer 3

Solved! 如果我使用<代码>Courier New,而不是monospace ,font-family,则行距与text-plain 版本完全相同。感谢大家。
