Adding tooltips to JTextPane

阅读更多关于 Adding tooltips to JTextPane

问题 I want to add some tooltips to only a certain text inside a JTextPane. As an example, if there is a reference link text inside the JTextPane I want to add a tooltip to that text to show the link. Is there any way I can achieve this functionality? 回答1: Good question. First Swing supports HTML, so to show tooltip with link you just have to say: comp.setToolTipText("<html><a href='http://www.google.com'>google</a></html>"); The problem is making this tooltip clickable. Unfortunately it is not

Getting raw text from JTextPane

阅读更多关于 Getting raw text from JTextPane

问题 In my application, I use a JTextPane to display some log information. As I want to hightlight some specific lines in this text (for example the error messages), I set the contentType as " text/html ". This way, I can format my text. Now, I create a JButton that copies the content of this JTextPane into the clipboard. That part is easy, but my problem is that when I call myTextPane.getText() , I get the HTML code, such as : <html> <head> </head> <body> blabla<br> <font color="#FFCC66"><b

setting JTextPane to content type HTML and using string builders

阅读更多关于 setting JTextPane to content type HTML and using string builders

I'm using string builders to append text to my JTextPane, I've set content type as pane.setContentType("text/html"); but the no text actually appears on my JTextPane. This is an example of my append: buildSomething.append("<b style=\"color:pink\">"+Birthday+"</span>"); Is there something I'm doing severely wrong? And how do I go about fixit it? Every time JTextPane.setText(...) is called a new content type is determined. Start the text with "<html>" and you've got HTML. A new document is created, in your case HTMLDocument. @mKorbel: the following creates every time HTML for the JTextPane.

How is word-wrapping implemented in JTextPane, and how do I make it wrap a string without spaces?

阅读更多关于 How is word-wrapping implemented in JTextPane, and how do I make it wrap a string without spaces?

How exactly is word-wrapping implemented in JTextPane? I'm trying to understand exactly how it works so that I can modify the behavior. Right now, if I have a standard JTextPane inside a JScrollPane, it will break text at spaces, but not inside long words - if there is a string of text without spaces that is wider than the window, it won't wrap/break and a horizontal scrollbar will appear. As the text width increases, the width of the ParagraphView (via getWidth()) increases to hold the text. This article by Lapitsky says that LabelView.getBreakWeight() returns View.ExcellentBreakWeight for
