• JOAL with JNLPAppletLauncher Problem

  - by user347445

  Hi, I am developing a Java Applet that makes use of JOAL. In order to avoid annoying dialogues I wanted to load JOAL with the JNLPAppletLauncher as it is shown on https://jogl-demos.dev.java.net/applettest-joal.html Unfortunately with this approach I get this exception: JNLPAppletLauncher.loadLibrary("joal_native") loading: C:\Users\Barbara\AppData\Local\Temp\jnlp-applet\jln7379734545861869319\jln1640167325490042232\joal_native.dll Exception in thread "AWT-EventQueue-2" java.lang.RuntimeException: Can not get proc address for method "alcCaptureCloseDevice": Couldn't set value of field "_addressof_alcCaptureCloseDevice" in class net.java.games.joal.impl.ALCProcAddressTable at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:113) at net.java.games.joal.impl.ALProcAddressLookup.resetALCProcAddressTable(ALProcAddressLookup.java:109) at net.java.games.joal.impl.ALCImpl.alcOpenDevice(ALCImpl.java:341) at net.java.games.joal.util.ALut.alutInit(ALut.java:69) at demos.devmaster.lesson1.SingleStaticSource.initialize(SingleStaticSource.java:194) at demos.devmaster.lesson1.SingleStaticSource.access$000(SingleStaticSource.java:57) at demos.devmaster.lesson1.SingleStaticSource$1.actionPerformed(SingleStaticSource.java:79) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) Caused by: java.lang.RuntimeException: Unable to find and load OpenAL library at net.java.games.joal.impl.ALProcAddressLookup$DynamicLookup.dynamicLookupFunction(ALProcAddressLookup.java:66) at com.sun.gluegen.runtime.ProcAddressHelper.resetProcAddressTable(ProcAddressHelper.java:106) ... 30 more I am using Firefox 3.6.3, Java 1.6._017 and am on a Windows 7 Machine. I also tried this on another computer with Windows XP and on one with Linux, always with the same result, so it does not seem to be specific for my computer. I also get the same result for IE8. Any ideas how I could fix this? Thank you very much.

But this but there is a problem with this! because after adding second panel it didn't add any other panel. my code is: import java.awt.BorderLayout; import java.awt.Dimension; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import javax.swing.AbstractButton; import javax.swing.ImageIcon; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.JPanel; import java.awt.GridBagLayout; import java.awt.GridBagConstraints; import java.awt.GridLayout; import javax.swing.JTextField; public class DrawImages extends JFrame{ int i; public DrawImages() { JButton btnNewButton = new JButton("New button"); i = 0; getContentPane().add(btnNewButton, BorderLayout.SOUTH); setMinimumSize(new Dimension(1000,150)); final JPanel panel = new JPanel(); panel.setSize(995, 145); getContentPane().add(panel, BorderLayout.CENTER); panel.setLayout(null); final JLabel lblNewLabel = new JLabel("New label"); lblNewLabel.setBounds(0, 0, 46, 14); panel.add(lblNewLabel); btnNewButton.addActionListener(new ActionListener() public void actionPerformed(ActionEvent paramActionEvent) { JPanel panel_1 = new JPanel(); //getContentPane().add(panel_1, BorderLayout.NORTH); panel_1.setLayout(null); JLabel imagelable = new JLabel(new ImageIcon("c:\\good.jpg")); imagelable.setBounds(70, 5, 105, 65); panel_1.add(imagelable); JLabel lblNewLabel_4 = new JLabel("Up Label"); lblNewLabel_4.setBounds(5, 5, 65, 35); panel_1.add(lblNewLabel_4); JLabel lblNewLabel_2 = new JLabel("Down Label"); lblNewLabel_2.setBounds(5, 25, 65, 65); panel_1.add(lblNewLabel_2); lblNewLabel.setText(""+i); panel_1.setBounds(5+170*i, 5, 170+170*i, 70); panel.add(panel_1); i++; } }); panel.setMinimumSize(new Dimension(995,150)); } public static void main(String[]args) { DrawImages drawImages = new DrawImages(); drawImages.setVisible(true); } }

• Search in Projects API

  - by Geertjan

  Today I got some help from Jaroslav Havlin, the creator of the new "Search in Projects API". Below are the steps to create a search provider that finds recently modified files, via a new tab in the "Find in Projects" dialog: Here's how to get to the above result. Create a new NetBeans module project named "RecentlyModifiedFilesSearch". Then set dependencies on these libraries: Search in Projects API Lookup API Utilities API Dialogs API Datasystems API File System API Nodes API Create and register an implementation of "SearchProvider". This class tells the application the name of the provider and how it can be used. It should be registered via the @ServiceProvider annotation.Methods to implement: Method createPresenter creates a new object that is added to the "Find in Projects" dialog when it is opened. Method isReplaceSupported should return true if this provider support replacing, not only searching. If you want to disable the search provider (e.g., there aren't required external tools available in the OS), return false from isEnabled. Method getTitle returns a string that will be shown in the tab in the "Find in Projects" dialog. It can be localizable. Example file "org.netbeans.example.search.ExampleSearchProvider": package org.netbeans.example.search; import org.netbeans.spi.search.provider.SearchProvider; import org.netbeans.spi.search.provider.SearchProvider.Presenter; import org.openide.util.lookup.ServiceProvider; @ServiceProvider(service = SearchProvider.class) public class ExampleSearchProvider extends SearchProvider { @Override public Presenter createPresenter(boolean replaceMode) { return new ExampleSearchPresenter(this); } @Override public boolean isReplaceSupported() { return false; } @Override public boolean isEnabled() { return true; } @Override public String getTitle() { return "Recent Files Search"; } } Next, we need to create a SearchProvider.Presenter. This is an object that is passed to the "Find in Projects" dialog and contains a visual component to show in the dialog, together with some methods to interact with it.Methods to implement: Method getForm returns a JComponent that should contain controls for various search criteria. In the example below, we have controls for a file name pattern, search scope, and the age of files. Method isUsable is called by the dialog to check whether the Find button should be enabled or not. You can use NotificationLineSupport passed as its argument to set a display error, warning, or info message. Method composeSearch is used to apply the settings and prepare a search task. It returns a SearchComposition object, as shown below. Please note that the example uses ComponentUtils.adjustComboForFileName (and similar methods), that modifies a JComboBox component to act as a combo box for selection of file name pattern. These methods were designed to make working with components created in a GUI Builder comfortable. Remember to call fireChange whenever the value of any criteria changes. Example file "org.netbeans.example.search.ExampleSearchPresenter": package org.netbeans.example.search; import java.awt.FlowLayout; import javax.swing.BoxLayout; import javax.swing.JComboBox; import javax.swing.JComponent; import javax.swing.JLabel; import javax.swing.JPanel; import javax.swing.JSlider; import javax.swing.event.ChangeEvent; import javax.swing.event.ChangeListener; import org.netbeans.api.search.SearchScopeOptions; import org.netbeans.api.search.ui.ComponentUtils; import org.netbeans.api.search.ui.FileNameController; import org.netbeans.api.search.ui.ScopeController; import org.netbeans.api.search.ui.ScopeOptionsController; import org.netbeans.spi.search.provider.SearchComposition; import org.netbeans.spi.search.provider.SearchProvider; import org.openide.NotificationLineSupport; import org.openide.util.HelpCtx; public class ExampleSearchPresenter extends SearchProvider.Presenter { private JPanel panel = null; ScopeOptionsController scopeSettingsPanel; FileNameController fileNameComboBox; ScopeController scopeComboBox; ChangeListener changeListener; JSlider slider; public ExampleSearchPresenter(SearchProvider searchProvider) { super(searchProvider, false); } /** * Get UI component that can be added to the search dialog. */ @Override public synchronized JComponent getForm() { if (panel == null) { panel = new JPanel(); panel.setLayout(new BoxLayout(panel, BoxLayout.PAGE_AXIS)); JPanel row1 = new JPanel(new FlowLayout(FlowLayout.LEADING)); JPanel row2 = new JPanel(new FlowLayout(FlowLayout.LEADING)); JPanel row3 = new JPanel(new FlowLayout(FlowLayout.LEADING)); row1.add(new JLabel("Age in hours: ")); slider = new JSlider(1, 72); row1.add(slider); final JLabel hoursLabel = new JLabel(String.valueOf(slider.getValue())); row1.add(hoursLabel); row2.add(new JLabel("File name: ")); fileNameComboBox = ComponentUtils.adjustComboForFileName(new JComboBox()); row2.add(fileNameComboBox.getComponent()); scopeSettingsPanel = ComponentUtils.adjustPanelForOptions(new JPanel(), false, fileNameComboBox); row3.add(new JLabel("Scope: ")); scopeComboBox = ComponentUtils.adjustComboForScope(new JComboBox(), null); row3.add(scopeComboBox.getComponent()); panel.add(row1); panel.add(row3); panel.add(row2); panel.add(scopeSettingsPanel.getComponent()); initChangeListener(); slider.addChangeListener(new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { hoursLabel.setText(String.valueOf(slider.getValue())); } }); } return panel; } private void initChangeListener() { this.changeListener = new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { fireChange(); } }; fileNameComboBox.addChangeListener(changeListener); scopeSettingsPanel.addChangeListener(changeListener); slider.addChangeListener(changeListener); } @Override public HelpCtx getHelpCtx() { return null; // Some help should be provided, omitted for simplicity. } /** * Create search composition for criteria specified in the form. */ @Override public SearchComposition<?> composeSearch() { SearchScopeOptions sso = scopeSettingsPanel.getSearchScopeOptions(); return new ExampleSearchComposition(sso, scopeComboBox.getSearchInfo(), slider.getValue(), this); } /** * Here we return always true, but could return false e.g. if file name * pattern is empty. */ @Override public boolean isUsable(NotificationLineSupport notifySupport) { return true; } } The last part of our search provider is the implementation of SearchComposition. This is a composition of various search parameters, the actual search algorithm, and the displayer that presents the results.Methods to implement: The most important method here is start, which performs the actual search. In this case, SearchInfo and SearchScopeOptions objects are used for traversing. These objects were provided by controllers of GUI components (in the presenter). When something interesting is found, it should be displayed (with SearchResultsDisplayer.addMatchingObject). Method getSearchResultsDisplayer should return the displayer associated with this composition. The displayer can be created by subclassing SearchResultsDisplayer class or simply by using the SearchResultsDisplayer.createDefault. Then you only need a helper object that can create nodes for found objects. Example file "org.netbeans.example.search.ExampleSearchComposition": package org.netbeans.example.search; public class ExampleSearchComposition extends SearchComposition<DataObject> { SearchScopeOptions searchScopeOptions; SearchInfo searchInfo; int oldInHours; SearchResultsDisplayer<DataObject> resultsDisplayer; private final Presenter presenter; AtomicBoolean terminated = new AtomicBoolean(false); public ExampleSearchComposition(SearchScopeOptions searchScopeOptions, SearchInfo searchInfo, int oldInHours, Presenter presenter) { this.searchScopeOptions = searchScopeOptions; this.searchInfo = searchInfo; this.oldInHours = oldInHours; this.presenter = presenter; } @Override public void start(SearchListener listener) { for (FileObject fo : searchInfo.getFilesToSearch( searchScopeOptions, listener, terminated)) { if (ageInHours(fo) < oldInHours) { try { DataObject dob = DataObject.find(fo); getSearchResultsDisplayer().addMatchingObject(dob); } catch (DataObjectNotFoundException ex) { listener.fileContentMatchingError(fo.getPath(), ex); } } } } @Override public void terminate() { terminated.set(true); } @Override public boolean isTerminated() { return terminated.get(); } /** * Use default displayer to show search results. */ @Override public synchronized SearchResultsDisplayer<DataObject> getSearchResultsDisplayer() { if (resultsDisplayer == null) { resultsDisplayer = createResultsDisplayer(); } return resultsDisplayer; } private SearchResultsDisplayer<DataObject> createResultsDisplayer() { /** * Object to transform matching objects to nodes. */ SearchResultsDisplayer.NodeDisplayer<DataObject> nd = new SearchResultsDisplayer.NodeDisplayer<DataObject>() { @Override public org.openide.nodes.Node matchToNode( final DataObject match) { return new FilterNode(match.getNodeDelegate()) { @Override public String getDisplayName() { return super.getDisplayName() + " (" + ageInMinutes(match.getPrimaryFile()) + " minutes old)"; } }; } }; return SearchResultsDisplayer.createDefault(nd, this, presenter, "less than " + oldInHours + " hours old"); } private static long ageInMinutes(FileObject fo) { long fileDate = fo.lastModified().getTime(); long now = System.currentTimeMillis(); return (now - fileDate) / 60000; } private static long ageInHours(FileObject fo) { return ageInMinutes(fo) / 60; } } Run the module, select a node in the Projects window, press Ctrl-F, and you'll see the "Find in Projects" dialog has two tabs, the second is the one you provided above:

• Êtes-vous plus Eclipse SWT/JFace ou Java FX ? Les choix stratégiques d'Oracle pourraient relancer le débat

  Êtes-vous plus Eclipse SWT/JFace ou Java FX ? Les choix stratégiques d'Oracle pourraient relancer le débat Avant l'arrivée de JavaFX et quand la boîte à outils Swing était largement mise en avant par Sun, la question se posait souvent sur le choix entre Swing et SWT/JFace la boîte à outils fournie par la plateforme Eclipse. Aujourd'hui Swing est en perte de vitesse et Oracle souhaite la remplacer par Java FX. Allons-nous voir apparaître un nouveau dilemme sur le choix de ces boîtes à outils Java pour le développement d'application de bureau ? La rubrique Java de Developpez.com vous propose aujourd'hui de partager votre opinion et votre expérience sur ces deux...

• Tracking work history in a git repo

  - by Code-Guru

  Previous related questions: Code bases for desktop and mobile versions of the same app Git branching and tagging best practices Question: I have split my repo into three directories (swing, android, and common) as suggested by @KarlBielefeldt in response to my previous question. Now I am jumping back and forth between developing my Android port and tweaking/adding features to my original Swing app. All of my commits are linear (fast-forward) and only my commit messages give hints indicating whether I'm working on my Swing app or my Android app. Is there a better way to keep track of the work flow in my git repo?

• Custom Java ListCellRenderer - Can't click JCheckBox

  Made a custom ListCellRenderer: import java.awt.Component; import javax.swing.JCheckBox; import javax.swing.JLabel; import javax.swing.JList; import javax.swing.JPanel; import javax.swing.ListCellRenderer; /** * * @author Spencer */ public class TaskRenderer implements ListCellRenderer { private Task task; private JPanel panel = new JPanel(); private JCheckBox checkbox = new JCheckBox(); private JLabel label = new JLabel(); public TaskRenderer() { panel.add(checkbox); panel.add(label); } public Component getListCellRendererComponent( JList list, Object value, int index, boolean isSelected, boolean cellHasFocus) { task = (Task) value; label.setText(task.getName()); return panel; } } Have a JList with each cell in it rendered using the above class, but the checkboxes in the panels for each cell cannot be clicked. Thought it had to do with it not getting focus. Any ideas? Thanks, Spencer

• Just curious, in NetBeans IDE 6.1 how can i get icons for my custom GUI components in the GUI editor

  - by Coder

  This is by no means really important, i was just wondering if the community knows how to put icons for my custom GUI components that show up in the NetBeans GUI designer. What i did was make several Swing components and then i use the menu options to add them to the GUI pallete, but they show up with "?" icons. It would be nice if they showed up with icons similar to swing components such as JButtons, especially for components which are subclassed for Swing components. Thanks!

• Access Denied Java FileWriter / FileInputStream

  - by Matt

  My program downloads a websites source code, modifies it, creates the file, and then reuploads it through the FTP. However, I receive the following error when trying to open the created file: java.io.FileNotFoundException: misc.html (Access is denied) at java.io.FileInputStream.open(Native Method) at java.io.FileInputStream.<init>(Unknown Source) at Manipulator.uploadSource(Manipulator.java:63) at Start.addPicture(Start.java:130) at Start$2.actionPerformed(Start.java:83) at javax.swing.AbstractButton.fireActionPerformed(Unknown Source) at javax.swing.AbstractButton$Handler.actionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.fireActionPerformed(Unknown Source) at javax.swing.DefaultButtonModel.setPressed(Unknown Source) at javax.swing.plaf.basic.BasicButtonListener.mouseReleased(Unknown Source) at java.awt.Component.processMouseEvent(Unknown Source) at javax.swing.JComponent.processMouseEvent(Unknown Source) at java.awt.Component.processEvent(Unknown Source) at java.awt.Container.processEvent(Unknown Source) at java.awt.Component.dispatchEventImpl(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.LightweightDispatcher.retargetMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.processMouseEvent(Unknown Source) at java.awt.LightweightDispatcher.dispatchEvent(Unknown Source) at java.awt.Container.dispatchEventImpl(Unknown Source) at java.awt.Window.dispatchEventImpl(Unknown Source) at java.awt.Component.dispatchEvent(Unknown Source) at java.awt.EventQueue.dispatchEvent(Unknown Source) at java.awt.EventDispatchThread.pumpOneEventForFilters(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForFilter(Unknown Source) at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.pumpEvents(Unknown Source) at java.awt.EventDispatchThread.run(Unknown Source) When I navigate to the folder directory and attempt to open "misc.html" with Notepad I receive Access is Denied. My code is fairly simple: File f = new File(page.sourceFileName); try { FileWriter out = new FileWriter(f); out.write(page.source); out.close(); } catch (IOException e) { e.printStackTrace(); } InputStream input = new FileInputStream(f); This is the vital excerpt from my program. I have copied this into a different test program and it works fine, I create a misc.html file and reopen it with both FileInputStream and manually. I would be worried about Administrator rights but the Test program works fine when I run it RIGHT after the problem program. I also have checked if the file exists and is a file with File methods and it is as well. Is this a result of me not closing a previous Input/Output properly? I've tried to check everything and I am fairly positive I close all streams as soon as they finish... Help! :)

• Problem to focus JTextField

  - by Tom Brito

  I have used the approach of the ComponentListener to call focus in JTextField within a dialog, but for this case is just not working, I don't know why. It shows the focus in the text field and fast change to the button. Run and see: import java.awt.Component; import java.awt.GridLayout; import java.awt.event.ComponentEvent; import java.awt.event.ComponentListener; import javax.swing.JDialog; import javax.swing.JLabel; import javax.swing.JOptionPane; import javax.swing.JPanel; import javax.swing.JPasswordField; import javax.swing.JTextField; public class User { private String username = ""; private String password = ""; public User() { // default constructor } public User(String username, String password) { this.username = username; this.password = password; } /** Create a panel containing the componet and tha label. */ public JPanel createLabeledComponent(JLabel label, Component comp) { GridLayout layout = new GridLayout(2, 1); JPanel panel = new JPanel(layout); panel.add(label); panel.add(comp); label.setLabelFor(comp); return panel; } public void showEditDialog() { JLabel usernameLbl = new JLabel(username); final JTextField usernameField = new JTextField(); usernameField.setText(username); JPanel usernamePnl = createLabeledComponent(usernameLbl, usernameField); JLabel passwordLbl = new JLabel(password); JPasswordField passwordField = new JPasswordField(password); JPanel passwordPnl = createLabeledComponent(passwordLbl, passwordField); Object[] fields = { "User:", usernamePnl, "Password:", passwordPnl }; JOptionPane optionPane = new JOptionPane(fields, JOptionPane.PLAIN_MESSAGE, JOptionPane.OK_CANCEL_OPTION, null, null); JDialog dialog = optionPane.createDialog("User Data"); dialog.addComponentListener(new ComponentListener() { public void componentShown(ComponentEvent e) { usernameField.requestFocusInWindow(); } public void componentResized(ComponentEvent e) {} public void componentMoved(ComponentEvent e) {} public void componentHidden(ComponentEvent e) {} }); dialog.setVisible(true); } public static void main(String[] args) { new User().showEditDialog(); } } Any idea how to solve this?

  I have been working with the Swing library for a long time, I'm working on a new project for school and due to the nature of the program it can't look like a generic/boring swing gui. So my question is does anyone know of an interesting java gui library that is not swing or awt?

  Hello! I'm triying to add an easing function to this code. So I replaced "swing" with "easeInOutQuint" (for example) but it's not working. I'm using jquery 1.4.2 and jquery easing 1.3 downloaded from here (http://gsgd.co.uk/sandbox/jquery/easing/) Any help will be greatly appreciated!

• JGridView

  - by Geertjan

  JGrid was announced last week so I wanted to integrate it into a NetBeans Platform app. I.e., I'd like to use Nodes instead of the DefaultListModel that is supported natively, so that I can integrate with the Properties Window, for example: Here's how: import de.jgrid.JGrid; import java.beans.PropertyVetoException; import javax.swing.DefaultListModel; import javax.swing.JScrollPane; import javax.swing.event.ListSelectionEvent; import javax.swing.event.ListSelectionListener; import org.book.domain.Book; import org.openide.explorer.ExplorerManager; import org.openide.nodes.Node; import org.openide.util.Exceptions; public class JGridView extends JScrollPane { @Override public void addNotify() { super.addNotify(); final ExplorerManager em = ExplorerManager.find(this); if (em != null) { final JGrid grid = new JGrid(); Node root = em.getRootContext(); final Node[] nodes = root.getChildren().getNodes(); final Book[] books = new Book[nodes.length]; for (int i = 0; i < nodes.length; i++) { Node node = nodes[i]; books[i] = node.getLookup().lookup(Book.class); } grid.getCellRendererManager().setDefaultRenderer(new OpenLibraryGridRenderer()); grid.setModel(new DefaultListModel() { @Override public int getSize() { return books.length; } @Override public Object getElementAt(int i) { return books[i]; } }); grid.setUI(new BookshelfUI()); grid.getSelectionModel().addListSelectionListener(new ListSelectionListener() { @Override public void valueChanged(ListSelectionEvent e) { //Somehow compare the selected item //with the list of books and find a matching book: int selectedIndex = grid.getSelectedIndex(); for (int i = 0; i < nodes.length; i++) { String nodeName = books[i].getTitel(); if (String.valueOf(selectedIndex).equals(nodeName)) { try { em.setSelectedNodes(new Node[]{nodes[i]}); } catch (PropertyVetoException ex) { Exceptions.printStackTrace(ex); } } } } }); setViewportView(grid); } } } Above, you see references to OpenLibraryGridRenderer and BookshelfUI, both of which are part of the "JGrid-Bookshelf" sample in the JGrid download. The above is specific for Book objects, i.e., that's one of the samples that comes with the JGrid download. I need to make the above more general, so that any kind of object can be handled without requiring changes to the JGridView. Once you have the above, it's easy to integrate it into a TopComponent, just like any other NetBeans explorer view.

• how to redirect terminal contents to a jtextpane?

  - by sonu thomas

  hi.. I was trying to run a java class file using java code.The aim was to direct the executing sequence of the terminal of fedora 10 into a frame with a textpane. My code is: import java.io.DataInputStream; import java.io.IOException; import javax.swing.JDialog; import javax.swing.JFrame; import javax.swing.JOptionPane; import javax.swing.JPanel; import javax.swing.JTextArea; import javax.swing.JTextPane; //import sun.reflect.ReflectionFactory.GetReflectionFactoryAction; public class file { /** * @param args */ /** * @param args * @throws IOException */ public static void main(String[] args) throws IOException{ // TODO Auto-generated method stub JDialog jj = new JDialog(); jj.setTitle("helllo"); String sssub1,sssub2,sssub3; String ss="C:/Users/sonu/Desktop/ourIDE/src/src/nn.java"; JPanel n = new JPanel(); jj.setContentPane(n); JTextPane tpn2=new JTextPane(); jj.getContentPane().add(tpn2); jj.setVisible(true); Runtime runtime; Process process; if(ss.indexOf(" ")==-1) { try { runtime= Runtime.getRuntime(); sssub1="/home/ss/Desktop/src/"; sssub2="nn"; process=runtime.exec("sh jrun.sh "+sssub1+" "+sssub2); DataInputStream data=new DataInputStream(process.getInputStream()); DataInputStream data_data=new DataInputStream(process.getErrorStream()); String s="",t=""; int ch; while((ch=data.read())!=-1){ s=s+(char)ch; } data.close(); while((ch=data_data.read())!=-1){ t=t+(char)ch; } data_data.close(); if(t.equals("")) { s+="\nNormal Termination."; tpn2.setText(s); } else tpn2.setText(t); }catch(Exception e){ System.out.println("Error executing file==>"+e);} } } } The content of **jrun.sh** is cd $1 java $2 When the content of **nn.java** was this: import java.io.*; class nn { public static void main(String[] ar)throws IOException { int i=90; BufferedReader dt = new BufferedReader(new InputStreamReader(System.in)); System.out.println("Enter"); //i=Integer.parseInt(dt.readLine()); line--notable System.out.println("i="+i); } } It worked smoothly But when I remove the comment on line--notable,it gave me Textpane with no content. The problem is : I cant read an input from nn.java Kindly give me a solution... If i am able to: get the terminal pop up with executing the nn.class,and i am able to enter the input,then it will do... Thanks in advance...

• Thread safe GUI programming

  - by James

  I have been programming Java with swing for a couple of years now, and always accepted that GUI interactions had to happen on the Event Dispatch Thread. I recently started to use GTK+ for C applications and was unsurprised to find that GUI interactions had to be called on gtk_main. Similarly, I looked at SWT to see in what ways it was different to Swing and to see if it was worth using, and again found the UI thread idea, and I am sure that these 3 are not the only toolkits to use this model. I was wondering if there is a reason for this design i.e. what is the reason for keeping UI modifications isolated to a single thread. I can see why some modifications may cause issues (like modifying a list while it is being drawn), but I do not see why these concerns pass on to the user of the API. Is there a limit imposed by an operating system? Is there a good reason these concerns are not 'hidden' (i.e. some form of synchronization that is invisible to the user)? Is there any (even purely conceptual) way of creating a thread safe graphics library, or is such a thing actually impossible? I found this http://blogs.operationaldynamics.com/andrew/software/gnome-desktop/gtk-thread-awareness which seems to describe GTK differently to how I understood it (although my understanding was the same as many people's) How does this differ to other toolkits? Is it possible to implement this in Swing (as the EDT model does not actually prevent access from other threads, it just often leads to Exceptions)

• UNESCO, J-ISIS, and the JavaFX 2.2 WebView

  - by Geertjan

  J-ISIS, which is the newly developed Java version of the UNESCO generalized information storage and retrieval system for bibliographic information, continues to be under heavy development and code refactoring in its open source repository. Read more about J-ISIS and its NetBeans Platform basis here. Soon a new version will be available for testing and it would be cool to see the application in action at that time. Currently, it looks as follows, though note that the menu bar is under development and many menus you see there will be replaced or removed soon: About one aspect of the application, the browser, which you can see above, Jean-Claude Dauphin, its project lead, wrote me the following: The DJ-Native Swing JWebBrowser has been a nice solution for getting a Java Web Browser for most popular platforms. But the Java integration has always produced from time to time some strange behavior (like losing the focus on the other components after clicking on the Browser window, overlapping of windows, etc.), most probably because of mixing heavyweight and lightweight components and also because of our incompetency in solving the issues. Thus, recently we changed for the JavaFX 2.2 WebWiew. The integration with Java is fine and we have got rid of all the DJ-Native Swing problems. However, we have lost some features which were given for free with the native browsers such as downloading resources in different formats and opening them in the right application. This is a pretty cool step forward, i.e., the JavaFX integration. It also confirms for me something I've heard other people saying too: the JavaFX WebView component is a perfect low threshold entry point for Swing developers feeling their way into the world of JavaFX.

• The Home Stretch: NetBeans IDE 7.1 Release Candidate

  - by TinuA

  The first release candidate build of NetBeans IDE 7.1 is live and available for download, which means the big release (GA) is expected any day soon.NetBeans IDE 7.1 delivers support for JavaFX 2.0, enabling the full compile, debug and profile development cycle for JavaFX 2.0 applications and keeping developers in sync with the latest from the Java platform. Beyond JavaFX support, 7.1 also provides significant Swing GUI Builder enhancements, CSS3 support, and visual debugging tools for JavaFX and Swing user interfaces.
