Setting the tab policy in Swing's JTextPane

问题 I want my JTextPane to insert spaces whenever I press Tab. Currently it inserts the tab character (ASCII 9). Is there anyway to customize the tab policy of JTextPane (other than catching "tab-key" events and inserting the spaces myself seems an)? 回答1: You can set a javax.swing.text.Document on your JTextPane. The following example will give you an idea of what I mean :) import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JTextPane; import javax.swing.text.AttributeSet;

Remove JTextPane's white background without setOpaque() over a translucent JFrame

由 Deadly 提交于 2019-12-02 08:28:53
问题 I have a Java code where I implemented a translucent JPanel with an image drawn on it with Graphics 2D. This image is a PNG that includes a white rectangle, 80% opaque, all over the JFrame. Now I need to add a JTextPane to display datas (I set it to use a custom font from the app package BTW), but I can't manage to make it translucent : its white background is opaque (even with the textPane.setOpaque(false); setting) and makes the transparency of my JFrame a bit useless... Wich is not cool.

问题 I am working in school project for creating a simple IDE. In it I am processing the entire program as a single string like... import java.io.*\npublic class A{\n...........\0 To trace all /*comments*/ "strings" 'c'haracters /**Documentation*/ I am maintaining an ArrayList<Pair> to mark all positions. Say, if (23,34) is an entry in ArrayList<Pair> comments , this means the characters between 23 and 34 are in a comment. And I acheived that using setCharacterAttributes defined in StyledDocument

HTML wrapped String creates a unwanted new line in JtextPane output

问题 When I concentrate a String with a HTML formatted string, and output the String to a JTextPane with a HTMLEditor kit, every appended String wrapped in the HTML tags appears to cause a new line: // Set the HTML Editor kit for JTExtPAne jtextPane.setEditorKit(new HTMLEditorKit()); String saveCurrentSentenceState = "Some String"; String newWord = "new word"; // wrap this in HTML tags // Create a HTML String String appendHTML = "<html><font color=\"red\">"+newWord+"<</font>"; // Concatenate with

由 徘徊边缘 提交于 2019-12-02 06:20:43
问题 I want to set the size of a tab character, \t, in a JTextPane to be 4 spaces wide. After Googling quite a bit I found some things that I will include here for what I have tried and maybe why they failed. How do you set the tab size in a JEditorPane? JTextPane is not a plain document. Java JTextpane Tab Size Eclipse raised some errors: Type mismatch: cannot convert from javax.swing.text.AttributeSet to javax.print.attribute.AttributeSet and The method setParagraphAttributes(javax.swing.text

Thanks 回答1: How about something like Highlighter.Highlight[] highlights = pseudoCodeTextPane.getHighlighter()

Java JTextPane + JScrollPane: de/activate automatic scrolling

问题 I'm currently writing a simple chat in Java and currently I'm stuck on this problem: I want my output JTextPane to behave like you would expect it to from a good chat, ie by default the text scrolls automatically when new text arrives (using outputfield.setCaretPosition(outputdocument.getLength())), but when the user scrolls up this should be disabled and of course re-enabled when the user scrolls to the bottom again. I tried toying around with the ScrollBars and all, but I can't seem to find

JTextPane append HTML string

由 泄露秘密 提交于 2019-12-02 03:49:56
I can parse the content of a JTextPane witout any problems in HTML: textPane = new JTextPane(); textPane.setContentType("text/html"); textPane.setText(<b>Hello!</b>); // ... setVisible(true); this results in Hello! But whenever I try to append a String to textPane, using styledDoc = (StyledDocument) textPane.getStyledDocument(); styledDoc.insertString(styledDoc .getLength(), <b>Goodbye!</b>, null ); (as seen in this question ), my output is Hello! <b>Goodbye!</b> (without whitespaces) - so the html formatting is skipped. How can I append a String to my JTextPane Object and keep the HTML

Can't remove extra line spacing in JTextPane for html content

由 做~自己de王妃 提交于 2019-12-02 03:22:20
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 code that generates the frame is: import java.awt.BorderLayout; import java.awt.Dimension; import
