jscrollpane

问题 I implemented the JScrollPane for a cleaner look inside my Page. function scrollPane() { $(".gwt-content").jScrollPane(); } A custom Widget gets added: $(".jspPane").append($(new Content()); works $(html).click(new Function() { public boolean f(Event e) { System.out.println("yo"); return true; } }); doesn't html.addClickHandler(new ClickHandler() { @Override public void onClick(ClickEvent event) { System.out.println("yo1"); } }); html is a HTML Widget with some Text and another HTML widget in

问题 Having an issue with a JScrollPane expanding its child JEditorPane just fine but forcing horizontal scroll bars when resizing it down again (instead of forcing the JEditorPane to recalculate wrapping). The basic flow of code is as follows: JFrame f = new JFrame(); JEditorPane jep = new JEditorPane(); JScrollPane jsp = new JScrollPane(jep); f.add(jsp); 回答1: It's a hack, but the best way I could find (without using ugly ScrollPaneManager s) was to implement a ComponentListener on the

问题 I have used this answer to get the functionality of Autoscrolling on a JTextArea. But it seems that it works only when the setEditable property of the same JTextArea is set to TRUE. Of course, i use a JScrollPane. I'm developing a chat application as a college project. The area where the messages are displayed is the very same JTextArea. I've used the 2nd set of code in the 1st answer in the above link. But I need it to make it work when setEditable is set to FALSE. It wont work even after

问题 I can't make the horizontal scrollbar appear. I've tried using JTextPane.setSize(), JTextPane.setPreferredSize() and no size method for JTextPane. I'm also using JScrollPane.setPreferredSize(). The vertical scroll bar appears, but the horizontal one doesn't. Here is an example: import java.awt.*; import java.awt.event.*; import javax.swing.*; public class Test { private int textPaneWidth = 500; private int textPaneHeigth = 200; private int scrollPaneWidth = 100; private int scrollPaneHeigth =

问题 I have a JTable in a JScrollPane, and the table gets new rows of data every once in a while. Eventually there are more rows of data than can be displayed at once and so the ScrollPane kicks in. I want the Scroll Pane to jump to the bottom (to its maximum value) every time new data is added, so I wrote this, which is called right after the new row is added: jScrollPane1.getVerticalScrollBar().setValue(jScrollPane1.getVerticalScrollBar().getMaximum()); It works quite well, but there is a

问题 So I have a JPanel that's inside a JScrollPane . Now I am trying to paint something on the panel, but it's always in same spot. I can scroll in all directions but it's not moving. Whatever I paint on the panel does not get scrolled. I already tried: A custom JViewPort switching between Opaque = true and Opaque = false Also I considered overriding the paintComponent method of the panel but that would be really hard to implement in my code. public class ScrollPanePaint{ public ScrollPanePaint()

问题 I am using Java and SWING, and I have a scrollpane with a rather large image added to it which works just fine right now, which means the scrolling functionality is working as intended. However in different locations on this image I need to add jButtons and be able to act on mouseclicks on these At the moment I got the following bit of code: (snippets, let me know if you require anything else) jButton1 = new JButton("CLICK"); jButton1.setBounds(0, 0, 100, 100); After that I add my

问题 I have a resizable JScrollPane inside a JDialog. That JScrollPane has a JPanel(called container) All these JScrollPane,JPanel and Jdialog are resizable. At the run time, another JPanel(called child) is added to the previous jPanel which is inside the JScrollPane of the JDialog.I want to get the size of the 'child' JPanel size. Before and after adding the 'child' JPanel to the 'container' JPanel, sizes of 'child' and 'container' JPanels are shown as 0 0. ( child.getSize() , container.getSize()

问题 private JPanel contentPane; public Driver() { setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setBounds(100, 100, 867, 502); contentPane = new JPanel(); contentPane.setBorder(new EmptyBorder(5, 5, 5, 5)); setContentPane(contentPane); contentPane.setLayout(null); final JTextArea textArea = new JTextArea(); textArea.setEditable(false); textArea.setBounds(10, 11, 831, 393); JScrollPane scroll = new JScrollPane(textArea); scroll.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR

问题 I generate a bunch of JPanels and then pass them into a class that extends JFrame. How do I add an indefinite number of JPanels to this JFrame. I was also reading about JScrollPane should I incorporate this somehow into the design? Example Code: class foo extends JPanel { //generate JPanels } class bar extends JFrame { //grab some amount of foo classes and put them into this JFrame and show it } Also is there anything I need to watch out for when showing this JFrame? Thanks 回答1: How do I add
