jtextpane

问题 How can I show an image I have selected from the file chooser in a my textpane (jTextPaneBody)? This is the code I have so far but I don't know what else needs to be added in order to achieve this. private void jButtonAttachActionPerformed(java.awt.event.ActionEvent evt) { JFileChooser jc = new JFileChooser(); jc.setDialogType(JFileChooser.OPEN_DIALOG); jc.showOpenDialog(null); File f = jc.getSelectedFile(); } 回答1: Start by taking a look at How to Use Labels and Reading/Loading an Image

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 6 years ago . I have an interesting task. Consider a String content with unknown length. I'd like to display content with a Font font with Justified text. I need to know what height this would take up if I specify the width .

问题 I have a basic text editor that can style documents (bold, underline, italicize, underline, align left/right/center, color, font size/family), and that all works great. The problem I'm having is that I want the style to set my buttons and boxes to the correct styling for where the caret is. Say, for example, I have the string the quick brown fox jumps over the lazy dog When I click between the u and i in quick, I want my italicize button to be toggled on to indicate that the text where the

问题 I have JTextPane, where are inserted 2 JLabels. If any of the labels are clicked, they change content from AAA to clicked. This code iterates over the elements in the JTextPane: for(int i = 0; i < tp.getDocument().getLength(); i++) { System.out.println(((StyledDocument) tp.getDocument()).getCharacterElement(i)); } How can I access the labels to print "clicked" "AAAA" to the std out? package texteditor; import java.awt.BorderLayout; import java.awt.Color; import java.awt.Dimension; import java

问题 I was trying to change background Color of JTextPane, contained like a Cell of JTable with problems related in this question JTable, update Colors Cell when LookAndFeel Nimbus or GTK are used I discovered later the bug (and not for me applicable solution) https://bugs.openjdk.java.net/browse/JDK-8058704?jql=order%20by%20lastViewed%20DESC UIManager.put("TextPane[Enabled].backgroundPainter", new Painter<JComponent>() { @Override public void paint(Graphics2D g, JComponent comp, int width, int

问题 I have the following issue with an app of mine, a basic IRC tool, which adds messages to a "JTextPane" with using "HTMLEditorKit" as an output GUI. I noticed, that randomly but over time, my app was using more and more memory, easily blowing up in crowded channels to already 300MB after just about 20 minutes of usage. I think the problem is somehow related to "JTextPane", because I can reproduce the issue with this code: package javaapplication26; import java.io.IOException; import java.util

问题 How to display lines one by one on a JTextPane and make a related JProgressBar ? I have this loop: int k; for (k=0; k<array_TXT.length; k++) { if (array_TXT[k] != null) { textPane.append( array_TXT[k] ); } } I'd like to append every line array_TXT[k] (string) on the JTextPane one by one after few seconds and it has to be synchronized to a JProgressBar . In this way every time k has a different value it will print on the text pane and the progress bar will always be related to those prints. I

问题 I'm trying to get JTextPane to word-wrap. I've searched this site and across the Internet and it seems that JTextPane is supposed to word-wrap by default- most trouble people have is with disabling the wrap or getting the wrap to work inside a JScrollPane. I've tried various combinations of TextPanes, ScrollPanes and JPanels, to no avail. Below is the simplest possible code tested that still has the problem (no wrap). public class Looseleaf extends JFrame{ public Looseleaf(){ this.setSize(200

问题 I have a JTextPane, into which I need to insert a JComponent. I'm using JTextPane.insertComponent(Component) The item is indeed inserted, but the vertical positioning is too high. Instead of having the bottom of the component aligned with the baseline of the current line of text, the component is way above that position, blocking out/over-painting lines of text appearing above. I have tried calling setAlignmentY(float) with various values, on both the inserted component and the JTextPane, but
