jtextpane

问题 I have an editor in which I want to check that selected text will not contain some words. If it contains those particular words, then I need to deselect the selection made by user. Is there any way to do that in JTextPane ? 回答1: Text selection is temporaray and contiguous. You can't unselect some text in the middle of a larger string of selected text. Maybe you are talking about highlighting. Check out the API for getHighlighter(). You can add/remove highlights and specify the start/end

问题 I'm in the process of developing a text editor that has a "macro system," where the user can reassign values to the keys on their keyboard -- so that when they press the letter a, it might print the letter "z" instead. (Really, it'll be used for math symbols, not other letters). Can anyone get me started on the Java code to reassign a value to a key within a JTextPane? If you need more details, let me know. Thank you! So far, this is what I have: public void keyPressed(KeyEvent evt) { /

问题 Just been trying to color the text in JTextPane - but the issue is cannot have different colors for text and the underline. How should I do that or is that even possible? The example below prints all the text and underline in RED. JTextPane pane = new JTextPane(); StyleContext context = new StyleContext(); Style style = pane.addStyle("Black", null); StyleConstants.setAlignment(style, StyleConstants.ALIGN_RIGHT); StyleConstants.setFontSize(style, 14); StyleConstants.setSpaceAbove(style, 4);

问题 I asked about this before, but, I decided to start a new thread with a SCCE, it compiles sucessfully but it doesn't insert the image. Can anyone troubleshoot as to why it does this? Thanks, Chris.

问题 I can't squeeze together the lines in a Java JTextPane if I set the content-type to text/html . I would like them as close together as they are when the content-type is text/plain , the default. The line-height , top-margin , ... CSS properties don't seem to help :(. This is the output of my sample program, that shows that the lines do take more space when a HTML editor handles the rendering: alt text http://lh6.ggpht.com/_Wx4sMDdKKdU/S8cYWIPKhzI/AAAAAAAAAig/4QzFwygmEBs/simpleTextPane.PNG The

问题 I am using a JTextPane to display characters and symbols, where the latter are represented by custom painted JComponents . For example, the text pane might show something like this: The text pane is user editable and it is allowed for the user to add more symbols via a button at any position and as a replacement for selected text. I do this via the JTextPane.insertComponent() method. At some point in the application I need to know what is currently being displayed in the text pane, and by
