将JTextPane设置为内容类型HTML并使用字符串构建器
ora*_*nge 5 html java swing jtextpane text-decorations
我正在使用字符串构建器将文本附加到我的JTextPane,我已将内容类型设置为pane.setContentType("text/html");但我的JTextPane上实际上没有显示文本.
这是我追加的一个例子:
buildSomething.append("<b style=\"color:pink\">"+Birthday+"</span>");
有什么我做错了吗？我该如何解决这个问题呢？
每次JTextPane.setText(...)调用时都会确定新的内容类型.用文本开始"<html>",你就有了HTML.
在您的案例中创建一个新文档HTMLDocument.
@mKorbel:以下每次为JTextPane创建HTML.
buildSomething.append("<html>");
buildSomething1.append("<html>");
for (int i = 0; i < 10; i++) {
buildSomething.append("<span style=\"color:red\">" + myBirthday + "</span>");
buildSomething1.append("<b style=\"color:blue\">" + myBirthday + "</b>");
}
- 我不得不将JTextPane中的属性`contentType`设置为`text/html`以使其工作. (13认同)

1.循环生成
buildSomething.append("<span style=\"color:pink\">" + myBirthday + "</span>");
第2位.循环生成相同的输出,我认为如果被包裹在里面<html> ..<html>并不重要因为有pane.setContentType("text/html");
和(我在这里发布的代码不正确<html> ..</html>)
buildSomething1.append("<html><span style=\"color:pink\">"
+ myBirthday + "</span></html>");
