写作样式的文本,以.docx文件 [英] Writing Styled Text to a .docx file
问题描述
我试图写会写文本到.docx文件的应用程序。我的应用程序使用的JTextPane,使用户可以写他/她想要什么,而且还提供了许多按钮,如粗体,字体颜色,字体大小...等。什么我在与被保持在JTextPane的文本的风格,当我写的.docx文件有问题。我是相当新的摇摆和Apache POI等等例如code和/或一个详细的解释将是有益的。
我已经是这样的:(垫指的JTextPane)
的FileOutputStream输出=新的FileOutputStream(文件);
XWPFDocument文档=新XWPFDocument();
XWPFParagraph段= document.createParagraph();
XWPFRun运行= paragraph.createRun();
run.setText(pad.getText());
文件撰写(输出);
output.close();
有关我的例子中我假设你使用的 一个HTMLEditorKit
在你的 的JTextPane
。然后我会解析 StyledDocument中的
窗格并设置相应textruns。
当然,这仅仅是一个启动,你需要分析所有可能的风格和自己进行转换他们在下面的循环。
我已经承认,我从来没有做过的东西与HTMLEditorKit和因此,我不知道如何妥善处理CSS.CssValues。

I'm trying to write an application that will write text to a .docx file. My application uses a JTextPane so the user can write whatever he/she wants, and it also provides many buttons such as bold, font color, font size... ect. What I'm having a problem with is maintaining the style of the text on the JTextPane to when I write to the .docx file. I'm fairly new to Swing and Apache POI so example code and/or a detailed explanation would be helpful.
What I have is this: (pad refers to the JTextPane)
FileOutputStream output = new FileOutputStream(file);
XWPFDocument document = new XWPFDocument();
XWPFParagraph paragraph = document.createParagraph();
XWPFRun run = paragraph.createRun();
run.setText(pad.getText());
document.write(output);
output.close();
For my example I assume you'd use a HTMLEditorKit
in your JTextPane
. I would then parse the StyledDocument
of the pane and set the textruns accordingly.
Of course this is just a starter, you'd need to parse all the possible styles and convert them yourself in the loop below.
I've to admit, that I've never done something with the HTMLEditorKit and therefore I don't know how to handle the CSS.CssValues properly.
