Java：Swing中的HTML，链接边距不起作用 [英] Java: HTML in Swing, link margin not working
问题描述
您好！
我正在尝试格式化Swing中的HTML内容。诸如颜色或文本修饰之类的格式正常工作。但是当谈到链接余量时它根本不起作用。
Hi there
I'm trying to format HTML content in Swing. Formattings such as color or text-decoration are working fine. But when it comes to margin of links it is not working at all.
这是我正在使用的所有CSS语法：
This is all the CSS syntax I'm using:
StyleSheet styleSheet = kit.getStyleSheet();
styleSheet.addRule("a {font : arial; text-decoration: none; color: #0174DF; margin-left: 50px}");
除了 margin-left 之外的所有内容都是工作。我在浏览器中测试了语法，它在那里工作正常。我也尝试使用 text-align：left 或 display：block 因为我发现一些文章指出链接边缘如果没有，就行不通。
everything, except the margin-left is working. I tested the syntax in a Browser and it works fine there. I also tried using text-align: left or display: block becouse I found some articles pointing out that margin of links would not work without.
使用以下HTML代码：
The following HTML code is used:
<html><head></head><body><div>
<a href="http://www.zhaw.ch" style="font-size: 50.24324324324324px">akamaitechnologies.com</a>
<a href="http://www.zhaw.ch" style="font-size: 17.37837837837838px">amazonaws.com</a>
<a href="http://www.zhaw.ch" style="font-size: 18.243243243243242px">cotendo.net</a>
<a href="http://www.zhaw.ch" style="font-size: 24.08108108108108px">facebook.com</a>
<a href="http://www.zhaw.ch" style="font-size: 17.594594594594597px">google.ch</a>
<a href="http://www.zhaw.ch" style="font-size: 55.0px">heise.de</a>
<a href="http://www.zhaw.ch" style="font-size: 16.08108108108108px">ip-plus.net</a>
<a href="http://www.zhaw.ch" style="font-size: 21.054054054054056px">ligatus.com</a>
</div></body></html>
HTML代码由库生成，无法修改。
The HTML code is generated by a library and can't be modified.
根据我对HTML / CSS的理解，无法将 margin 样式信息添加到内联对象，如链接，因为margin-top或保证金底部是不可能的。 margin-left oder margin-right但不应该是一个问题。
From my understanding of HTML/CSS it is not possible to add margin style information to an inline object like a link becouse margin-top or margin-bottom is not possible. margin-left oder margin-right however should not be a problem.
thx

推荐答案
这是我放弃或疯狂（或两者兼而有之）之前的最后一次尝试。
This is my last attempt before I give up or go mad (or both).
import javax.swing.*;
class TestHtmlIndent {
public static void main(String[] args) {
String raw =
"<html><head></head><body><div>" +
"<a href=\"http://a.b\" style=\"font-size: 20px\">akamaitechnologies.com</a>" +
"<a href=\"http://a.b\" style=\"font-size: 17px\">amazonaws.com</a>" +
"<a href=\"http://a.b\" style=\"font-size: 18px\">cotendo.net</a>" +
"<a href=\"http://a.b\" style=\"font-size: 24px\">facebook.com</a>" +
"<a href=\"http://a.b\" style=\"font-size: 17px\">google.ch</a>" +
"<a href=\"http://a.b\" style=\"font-size: 25px\">heise.de</a>" +
"<a href=\"http://a.b\" style=\"font-size: 16px\">ip-plus.net</a>" +
"<a href=\"http://a.b\" style=\"font-size: 21px\">ligatus.com</a>" +
"</div></body></html>";
String style =
"<style type='text/css'>" +
"body {width: 600px;}" +
".cloudLink {text-decoration: none; color: #0174DF; " +
"font-family: helvetica, arial, sans-serif;}" +
"</style>";
raw = raw.replace("<head></head>", "<head>" + style + "</head>");
String space4 = "  ";
String space20 = space4 + space4 + space4 + space4 + space4;
final String processed1 = raw.replace(
"<a ", space20 + "<a class='cloudLink' ");
Runnable r = new Runnable() {
public void run() {
JOptionPane.showMessageDialog(null, processed1);
}
};
SwingUtilities.invokeLater(r);
}
}
