jtextpane

问题 So I am trying to make the text in a JTextPane double spaced. Here's my code: MutableAttributeSet attrs = editor.getInputAttributes(); StyleConstants.setLineSpacing(attrs, 2); editor.getStyledDocument().setParagraphAttributes(0, doc.getLength() + 1, attrs, true); The problem with this, is, the curser (caret) is as big as three or four line spaces. How can I resize the caret to normal size? Here is a screen snip 回答1: Try this: editor.setCaret(new DefaultCaret() { public void paint(Graphics g)

问题 I'm looking for a quick way to find a String in a JTextPane and change the style there, so it gets highlighted. What I currently have is something like this (tpOutput is the JTextPane in question, strSearch the String to be searched.. duh): int index = tpOutput.getText().indexOf(strSearch); StyledDocument doc = tpOutput.getStyledDocument(); doc.setCharacterAttributes(i, strSearch.length(), doc.getStyle("exampleStyle") , false); However, as beautiful as that would be if it worked, it counts

问题 I need to not allow any characters to be entered after X have been typed. I need to send a beep after X characters have been typed.

I can't get this to notify the user when they have gone over (it doesn't work until they press enter). This is a sample of what I have. public class EndCycleTextAreaRenderer

问题 I am new to GUI programming. While practicing KeyEvent handling on Java Swing JTextarea I face one problem. The listener interface is implemented by text area itself. When I pressed VK_ENTER key in text area I get text from text area then I displayed that text into JTextPane . After that I set text as empty string on text area. Here I used keyPressed key event - it is creating one new line in text area but already I set text area row as 0 (zero). Actually I want one row in text area I don't

问题 My application's main JFrame contains a JTextPane. While it has focus, it consumes all keyboard shortcuts ("accelerators") instead of passing them on to the JFrame's JMenu. This means that while it has focus, eg ctrl-n for "New Document" doesn't work. Obviously it's useful that it handles ctrl-A/C/V/X correctly for select all/copy/paste/cut, but how do I convince it not to swallow the other shortcuts? 回答1: I think at the end of your key listener functions you should be able to say... this

问题 I'm displaying RSS feed in my JTextPanel. Result displayed doesn't go to a new line. How can I insert \n in JTextPane? Thanks! writeNews class: public String writeNews() { String result = ""; try { DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder(); URL u = new URL("http://thestar.com.my.feedsportal.com/c/33048/f/534600/index.rss"); Document doc = builder.parse(u.openStream()); NodeList nodes = doc.getElementsByTagName("item"); for(int i=0;i<nodes.getLength()

问题 How do I get JTextPane to scroll? In this example, JScrollPane is employed but as running the code will reveal, the scroll bar can be displayed but it is not functional. import java.awt.BorderLayout; import javax.swing.*; import javax.swing.text.*; public class JTextPaneTester { JTextPane jtp = new JTextPane(); StyledDocument doc; Style style; JScrollPane jsp = new JScrollPane(jtp); JTextPaneTester() { doc = (StyledDocument)jtp.getDocument(); style = doc.addStyle("fancy", null); jsp

问题 I'm trying to print out some simple RTF-formatted text to a laser printer using a JTextPane . The result looks fine on a software PDF printer (FreePDF XP), but the text doesn't have proper space between it's formatted parts when print to a real printer.
