jtextpane

问题 I have a word wrapping issue when using JTextPane. I think it's my IDE (JCreator) but when i use the source everyone else is using I get several errors. Sorry for the line breaks... Could it be my IDE or can someone please let me know the right way of doing this. TIA -Roland The source I am using can be found at http://java-sl.com/tip_html_letter_wrap.html lol.. I forgot the space! Thanks all. It is going to proceed. I have been programming all night and am a little groggy. Best of luck

问题 I'm trying to get a JTextPane to adjust its height according to whatever content I feed it. All I can do is to set a fixed height in pixels using Dimension. How do I make the JTextPane collapse/expand so it will fit to contents? I might add that I use this in a GridBagLayout 'ed JPanel that has been added to a JScrollPane . 回答1: I don't know any direct way to do it, but this may give you some ideas: import java.awt.*; import java.awt.event.*; import javax.swing.*; import javax.swing.text.*;

问题 I am new in Java, and I just found this piece of code in StackOverflow: ResizeTextArea. I want to use JTextPane instead of JTextArea . In JTextPane , there is no setRows() method to change the number of the lines. Any help would be appreciated. 回答1: The height of individual lines in a StyledDocument can vary, so the notion of limiting rows in a JTextPane is not useful. You can limit the preferred size of the scroll pane's viewport to some useful fraction of main panel's size, as shown here

问题 So I've created my own text pane class (extending JTextPane) and I'm using the method below to add text to it. However, the pane needs to be editable for it to add the text, but this allows a user to edit what is in the pane as well. Can anyone tell me how to add text to the pane without letting the user manipulate what is there? public void appendColor(Color c, String s) { StyleContext sc = StyleContext.getDefaultStyleContext(); AttributeSet aset = sc.addAttribute(SimpleAttributeSet.EMPTY,

问题 I am trying to create simple IDE and coloring my JTextPane based on Strings (" ") Comments (// and /* */) Keywords (public, int ...) Numbers (integers like 69 and floats like 1.5) The way i color my source code is by overwritting the insertString and removeString methods inside the StyledDocument. After much testing, i have completed comments and keywords. Q1: As for my Strings coloring, I color my strings based on this regular expression: Pattern strings = Pattern.compile("\"[^\"]*\"");

问题 I'm using JTextPane to log some data from a network application and after the program runs for about more than 10 hours or so I get memory heap error. Text continues to get added to the JTextPane which keeps increasing memory usage. Is there anyway I can make the JTextPane act like a command prompt window? Should I get rid of the old text as new text comes in? This is the method I'm using to write to the JTextPane. volatile JTextPane textPane = new JTextPane(); public void println(String str,

问题 I am making a network application that has a chat function. On the chat I have one JTextPane for displaying messages and one more for input. Then I have some buttons that allow to add style on the input text(bold,italic,font size,colour). The text is formatted correctly on input pane , although when moved to the display pane(once the correct JButton is pressed) it only has the format of last character. How can I move the text while keeping its original format?For example if I write "Hello
