[英]Is there an RTF display widget in SWT
I would like to display an RTF document in an SWT (actually Eclipse RCP) application. 我想在SWT(实际上是Eclipse RCP)应用程序中显示RTF文档。
I know there is a Swing widget for displaying and editing RTF text, but it is Swing and quite alien in look and feel when used in the otherwise platform (not to mention that to the last of my knowledge it did not display images and had only limited support for formatting) 我知道有一个用于显示和编辑RTF文本的Swing小部件,但是当在其他平台上使用时,它是Swing并且外观和感觉相当陌生(更不用说我最后的知识它没有显示图像而且只有有限的格式支持)
Other options is to use COM interface on windows, but that works only on the windows platform and requires that an ActiveX RichEdit contol be installed on the customer machine... which can make the deployment of the application quite horrendous... 其他选择是在Windows上使用COM接口,但这只适用于Windows平台,并且要求在客户机器上安装ActiveX RichEdit控件...这可能会使应用程序的部署非常可怕......
What are the other options for displaying rich documents inside Eclipse/SWT application? 在Eclipse / SWT应用程序中显示富文档的其他选项有哪些?
Why not first read the RTF text into a StyledDocument using the RTFEditorKit and then writing the StyledDocument to a StringWriter using the HTMLEditorKit? 为什么不首先使用RTFEditorKit将RTF文本读入StyledDocument,然后使用HTMLEditorKit将StyledDocument写入StringWriter?
String rtf = "whatever";
BufferedReader input = new BufferedReader(new StringReader(rtf));
RTFEditorKit rtfKit = new RTFEditorKit();
StyledDocument doc = (StyledDocument) rtfKit.createDefaultDocument();
rtfEdtrKt.read( input, doc, 0 );
input.close();
HTMLEditorKit htmlKit = new HTMLEditorKit();
StringWriter output = new StringWriter();
htmlKit.write( output, doc, 0, doc.getLength());
String html = output.toString();
And then display the HTML? 然后显示HTML?
Actuall, I've just found another widget that is quite promising atm: Actuall,我刚刚找到另一个非常有前景的小部件:

You might want to use the Swing control with the AWT/SWT bridge . 您可能希望将Swing控件与AWT / SWT桥一起使用 。 I used this to embed OpenOffice into an SWT app: 我使用它将OpenOffice嵌入到SWT应用程序中:

You may use swt.custom.StyledText. 您可以使用swt.custom.StyledText。 That has many features to change the look of the text. 这有许多功能可以改变文本的外观。 But I don't think it can load or save RTF right now. 但我认为它现在不能加载或保存RTF。
I once wrote an HTML editor with it, but it is quite difficult, since the StyledText model to add styles to a part of the text is so alien compared to the way HTML/RTF works. 我曾经用它编写了一个HTML编辑器,但这很困难,因为与HTML / RTF的工作方式相比,StyledText模型在文本的一部分中添加样式是如此的陌生。
AFAIK you can directly print from this control, which internally creates an RTF representation of the contents. AFAIK可以直接从此控件打印,该控件在内部创建内容的RTF表示。 But that's not exactly what you asked for. 但这并不是你要求的。
I'm not sure of a way to do it without using ActiveX. 如果不使用ActiveX,我不知道如何做到这一点。 If you do go this direction you might want to look into the IBM Container for ActiveX Documents , which is supposed to allow better integration of documents. 如果您这样做,您可能需要查看IBM Container for ActiveX Documents ,它应该允许更好地集成文档。
