我正在使用字符串構建器將文本附加到我的JTextPane，我已將內容類型設置爲pane.setContentType("text/html");，但沒有文本實際出現在我的JTextPane上。將JTextPane設置爲內容類型HTML並使用字符串構建器
這是我追加的例子：
buildSomething.append("<b style=\"color:pink\">"+Birthday+"</span>");
有什麼我做的嚴重錯誤？我該如何解決它？
每次調用JTextPane.setText(...)時，都會確定新的內容類型。用"<html>"開始文本，你已經有了HTML。
創建一個新文檔，在你的情況HTMLDocument。
@mKorbel：以下每次爲JTextPane創建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>");
}
@Joop埃根
1日。循環產生
buildSomething.append("<span style=\"color:pink\">" + myBirthday + "</span>");
第二。循環產生相同的輸出，我想是因爲有pane.setContentType("text/html");
和（不正確的代碼，我張貼在這裏<html> ..</html>）如果包裹在裏面<html> ..<html>與否不要緊
buildSomething1.append("<html><span style=\"color:pink\">"
+ myBirthday + "</span></html>");

so'buildSomething.append（「」+ Birthday +「」）;'？我試過了，但它仍然是一樣的。 – orange 2012-01-30 22:05:21
你做了'buildSomething = new StringBuilder（）; buildSomething.append（「」+ ...）; textPane.setText（buildSomething.toString（））;'？ – 2012-01-30 22:30:45
