  • GroupLayout: JScrollPane in TextArea is not working

    - by Dozent
    i'm new in java and recently started to develop an simple application. For the moment i have a problem with JScrollPanne, it's not able to scroll down (or up) when the text in textarea more than size of area. I have looked to some solutions, but all of them were for FlowLayot (GridLayout and BoxLayout), but not for GroupLayout. Here is the code: JPanel conent_p = new JPanel(); conent_p.setBorder(new TitledBorder(null, "", TitledBorder.LEADING, TitledBorder.TOP, null, null)); JLabel lblItemName = new JLabel("Item name:"); itemField = new JTextField(); itemField.setColumns(10); JLabel lblMxPrice = new JLabel("Max price:"); mpriceField = new JTextField(); mpriceField.setColumns(10); JLabel lblQuantity = new JLabel("Quantity:"); quanField = new JTextField(); quanField.setColumns(10); JLabel lblDelivery = new JLabel("Delivery:"); delivField = new JTextField(); delivField.setColumns(10); JLabel lblLogcat = new JLabel("LogCat:"); final JTextArea txtConsole = new JTextArea(); txtConsole.setEditable(false); txtConsole.setLineWrap(true); txtConsole.setWrapStyleWord(true); sbrText = new JScrollPane(txtConsole); sbrText.setVerticalScrollBarPolicy(JScrollPane.VERTICAL_SCROLLBAR_ALWAYS); // Now create a new TextAreaOutputStream to write to our JTextArea control and wrap a // PrintStream around it to support the println/printf methods.

  • Using JDialog with Tabbed Pane to draw different pictures [migrated]

    - by Bryam Ulloa
    I am using NetBeans, and I have a class that extends to JDialog, inside that Dialog box I have created a Tabbed Pane. The Tabbed Pane contains 6 different tabs, with 6 different panels of course. What I want to do is when I click on the different tabs, a diagram is supposed to be drawn with the paint method. My question is how can I draw on the different panels with just one paint method in another class being called from the Dialog class? Here is my code for the Dialog class: package GUI; public class NewJDialog extends javax.swing.JDialog{ /** * Creates new form NewJDialog */ public NewJDialog(java.awt.Frame parent, boolean modal) { super(parent, modal); initComponents(); } /** * This method is called from within the constructor to initialize the form. * WARNING: Do NOT modify this code.

  • Mixed alignment with Java Swing's GroupLayout

    - by zigdon
    I'm trying to build a GUI window in my application. What I'm trying to do is have a window, with a few buttons at the top, and a large text area. Something like this: +--------------------------------------------------+ | [button1] [button2] [button3] | | +----------------------------------------------+ | | | text area | | | | | | | | | | | | | | | +----------------------------------------------+ | +--------------------------------------------------+ I'm almost there, using GroupLayout: layout.setHorizontalGroup( layout.createParallelGroup() .addGroup(layout.createSequentialGroup() .addComponent(button1) .addComponent(button2)) .addComponent(closeWindow)) .addComponent(textarea1) ); layout.setVerticalGroup( layout.createSequentialGroup() .addGroup(layout.createParallelGroup() .addComponent(button1) .addComponent(button2) .addComponent(button3)) .addComponent(textarea) ); The problem is that this ends up with button3 aligned to the left, with the other two. I can't seem to figure out how I can specify the alignment on just that one button. I can do GroupLayout.Alignment.TRAILING on the entire button bar, but that hits all 3 buttons, which is also not quite right. So what's the correct approach? Since the alignment only applies for Parallel Groups, I don't think having a HorizontalGroup with two Sequential Groups in it will help? What am I missing?

  • Making a app show inside a GUI in Java

    - by José
    Hello. I have one problem I've been dealing with for this week. You see, I'm new to Java, so that's probably it... Anyways, I've started a project out of pure curiosity. I had it done in Java, but in plain CMD-style, which is not very pretty. It calls one of my ten programs, chosen by the user using "Case". Eg.: If you type 1, it will go to program 1. After you finish it, it goes back to selection until the user press 0. After that, I've been trying to make a GUI for it. I've been able to create the selector alone and make it respond to the numbers chosen. If you press 1 and click ok, it will tell you you've chosen program 1. I, however, have not been able to make it run the program. I've been trying to make the program show up in a jPanel, part of the main GUI. I failed miserably. The program runs in separate but I can't make them run together like the CMD one. The apps were made in Eclipse SDK 3.5.2 The GUIs were made in Netbeans IDE 6.8 Here's the code for the GUI only (the prints are in PT-BR, my native language): Main program: /* * To change this template, choose Tools | Templates * and open the template in the editor. */ /* * ProgramasGUI.java * * Created on 31/01/2010, 22:56:19 */ package Main; import Main.Prog1; /** * * @author Zeh® */ public class ProgramasGUI extends javax.swing.JFrame { /** Creates new form ProgramasGUI */ public ProgramasGUI() { initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.

  • what's the difference between DEFAULT_SIZE and PREFERRED_SIZE?

    - by CD1
    hi, I'm using Swing GroupLayout and I'm confused about the values GroupLayout.DEFAULT_SIZE and GroupLayout.PREFERRED_SIZE. I never know when to use each one of them in methods like GroupLayout.addComponent(Component, int, int, int). suppose I have this code: GroupLayout l = ...; l.setHorizontalGroup(l.createSequentialGroup() .addComponent(tf1) .addComponent(tf2)); l.setVerticalGroup(l.createParallelGroup() .addComponent(tf1) .addComponent(tf2)); there are two JTextFields on a single line laid out with GroupLayout (one sequential group horizontally and one parallel group vertically). if I resize the window now, both components get the available space (50% each). but I want only the first text field to grow/shrink horizontally and only the second text field to grow/shrink vertically. what values of min, pref and max should I use to accomplish that? I know I can just try it and see what combination works but I'd like to know the reasoning behind this problem.

  • using ResultSet.Previous method not working in Java using .mdb file OBDC

    - by jsonnie
    Hello, I'm currently having an issue with my open result set not working how I believe it should. The only function that is currently working is the next() method, nothing else will work. If the project is placed into a debug mode you can follow through actionperformed event on the button it hits the previous() method and jumps over the remaining code in the method. If someone could point me in the right direction it would be truly appreciated.

  • Netbeans Java SE GUI Builder: private initComponents() problem

    - by maSnun
    When I build a GUI for my Java SE app with Netbeans GUI builder, it puts all the codes in the initComponents() method which is private. I could not change it to public. So, all the components are accessible only to the class containing the UI. I want to access those components from another class so that I can write custom event handlers and everything. Most importantly I want to separate my GUI code and non-GUI from each other. I can copy paste the GUI code and later make them public by hand to achieve what I want. But thats a pain. I have to handcraft a portion whenever I need to re-design the UI. What I tried to do: I used the variable identifier to make the text box public. Now how can I access the text box from the Main class? I think I need the component generated in a public method as well. I am new to Java. Any helps? Here's the sample classes: The UI (uiFrame.java) /* * To change this template, choose Tools | Templates * and open the template in the editor. */ /* * uiFrame.java * * Created on Jun 3, 2010, 9:33:15 PM */ package barcode; import java.util.logging.Level; import java.util.logging.Logger; import javax.swing.JFileChooser; import javax.swing.UIManager; import javax.swing.UnsupportedLookAndFeelException; import net.sourceforge.barbecue.output.OutputException; /** * * @author masnun */ public class uiFrame extends javax.swing.JFrame { /** Creates new form uiFrame */ public uiFrame() { try { try { // Set cross-platform Java L&F (also called "Metal") UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); } catch (ClassNotFoundException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } catch (InstantiationException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } catch (IllegalAccessException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } catch (UnsupportedLookAndFeelException ex) { Logger.getLogger(uiFrame.class.getName()).log(Level.SEVERE, null, ex); } } finally { } initComponents(); } /** This method is called from within the constructor to * initialize the form. * WARNING: Do NOT modify this code.

  • How do I get a JComponent to resize after calling `setVisible(true)`?

    - by iWerner
    Our application displays a 2D view of our data (mainly maps) and then allows the user to change to a 3D view. The 2D and 3D views are generated by custom C++ code that is SWIG'ed into our Swing GUI and wrapped within a JComponent. These JComponents are then displayed within another parent JComponent. Our problem is that when we change from the 2D to the 3D view and then back to the 2D view, when we resize the window the 2D view does not get resized. The resize events don't get sent to the 2D view. Our application runs under Linux (Fedora 11). We're running Java version 1.6.0_12. Here is some sample code in which I've replaced the 2D view and 3D view with two 2 JButtons, that produces the same behaviour. Once you go to 3D and then back to 2D, resizing the window does not cause the 2D view to be resized. /* TestFrame.java * Compile with: $ javac TestFrame.java * Run with: $ java TestFrame */ import java.awt.BorderLayout; import java.awt.Container; import java.awt.event.ComponentEvent; import java.awt.event.ComponentListener; import javax.swing.JButton; public class TestFrame extends javax.swing.JFrame { private boolean mode2D = true; private JButton view2D = null; private JButton view3D = null; private Container parent = null; public TestFrame() { initComponents(); containerPanel.setLayout(new BorderLayout()); view2D = new JButton("2D View"); view2D.addComponentListener(new MyListener("2D VIEW")); containerPanel.add(view2D); } private void changerButtonActionPerformed(java.awt.event.ActionEvent evt) { if (parent == null) { parent = view2D.getParent(); } if (mode2D) { System.out.println("Going from 2D to 3D"); view2D.setVisible(false); if (view3D != null) { view3D.setVisible(true); } else { view3D = new JButton("3D View"); view3D.addComponentListener(new MyListener("3D VIEW")); parent.add(view3D); } ((JButton) evt.getSource()).setText("Change to 2D"); mode2D = false; } else { System.out.println("Going from 3D to 2D"); view3D.setVisible(false); view2D.setVisible(true); ((JButton) evt.getSource()).setText("Change to 3D"); mode2D = true; } } public static void main(String args[]) { java.awt.EventQueue.invokeLater(new Runnable() { public void run() { new TestFrame().setVisible(true); } }); } private javax.swing.JPanel containerPanel; private javax.swing.JButton changerButton; private class MyListener implements ComponentListener { private String name; public MyListener(String name) { this.name = name; } @Override public void componentHidden(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Hidden"); } @Override public void componentResized(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Resized"); } @Override public void componentShown(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Shown"); } @Override public void componentMoved(ComponentEvent event) { System.out.println("@@@ [" + name + "] component Moved"); } }; @SuppressWarnings("unchecked") private void initComponents() { containerPanel = new javax.swing.JPanel(); changerButton = new javax.swing.JButton(); setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE); containerPanel.setBorder(new javax.swing.border.MatteBorder(null)); javax.swing.GroupLayout containerPanelLayout = new javax.swing.GroupLayout(containerPanel); containerPanel.setLayout(containerPanelLayout); containerPanelLayout.setHorizontalGroup( containerPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGap(0, 374, Short.MAX_VALUE) ); containerPanelLayout.setVerticalGroup( containerPanelLayout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGap(0, 239, Short.MAX_VALUE) ); changerButton.setText("Change to 3D"); changerButton.addActionListener(new java.awt.event.ActionListener() { public void actionPerformed(java.awt.event.ActionEvent evt) { changerButtonActionPerformed(evt); } }); javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane()); getContentPane().setLayout(layout); layout.setHorizontalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addGroup(layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addComponent(containerPanel, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) .addComponent(changerButton)) .addContainerGap()) ); layout.setVerticalGroup( layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING) .addGroup(layout.createSequentialGroup() .addContainerGap() .addComponent(containerPanel, javax.swing.GroupLayout.DEFAULT_SIZE, javax.swing.GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE) .addPreferredGap(javax.swing.LayoutStyle.ComponentPlacement.RELATED) .addComponent(changerButton) .addContainerGap()) ); pack(); } } (My apologies for the Netbeans generated GUI code) I should mention that when we call parent.remove(view2D) and parent.add(view3D) to change the views the X Windows ID of our 3D view changes and we're unable to get our 3D view back. Therefore parent.remove(view2D) and parent.add(view3D) is not really a solution and we have to call setVisible(false) and setVisible(true) on the JComponents that contain our 2D and 3D views in order to hide and show them. Any help will be greatly appreciated.

  • Displaying emails in a JTable (Java Swing)

    - by Paul
    Hi I'm new to all this. I have been trying to display fetched emails in a JTable using the JavaMail add-on. However when I ask the program to set the value it never does.

  • Alternative to array_shift function

    - by SoLoGHoST
    Ok, I need keys to be preserved within this array and I just want to shift the 1st element from this array. Actually I know that the first key of this array will always be 1 when I do this: // Sort it by 1st group and 1st layout. ksort($disabled_sections); foreach($disabled_sections as &$grouplayout) ksort($grouplayout); Basically I'd rather not have to ksort it in order to grab this array where the key = 1. And, honestly, I'm not a big fan of array_shift, it just takes to long IMO. Is there another way. Perhaps a way to extract the entire array where $disabled_sections[1] is found without having to do a foreach and sorting it, and array_shift. I just wanna add $disabled[1] to a different array and remove it from this array altogether. While keeping both arrays keys structured the way they are. Technically, it would even be fine to do this: $array = array(); $array = $disabled_sections[1]; But it needs to remove it from $disabled_sections. Can I use something like this approach... $array = array(); $array = $disabled_sections[1]; $disabled_sections -= $disabled_sections[1]; Is something like the above even possible?? Thanks.

Any ideas? import android.app.AlertDialog; import android.app.ExpandableListActivity; import android.content.ContentUris; import android.content.Context; import android.database.Cursor; import android.net.Uri; import android.os.Bundle; import android.provider.Contacts.People; import android.view.View; import android.widget.ExpandableListAdapter; import android.widget.SimpleCursorTreeAdapter; import android.widget.TextView; import android.widget.ExpandableListView.OnChildClickListener; public class ShowContacts extends ExpandableListActivity implements OnChildClickListener { private int mGroupIdColumnIndex; private String mPhoneNumberProjection[] = new String[] { People.Phones._ID, People.NUMBER // CHANGE HERE }; private ExpandableListAdapter mAdapter; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // Query for people Cursor groupCursor = managedQuery(People.CONTENT_URI, new String[] {People._ID, People.NAME}, null, null, null); // Cache the ID column index mGroupIdColumnIndex = groupCursor.getColumnIndexOrThrow(People._ID); // Set up our adapter mAdapter = new MyExpandableListAdapter(groupCursor, this, android.R.layout.simple_expandable_list_item_1, android.R.layout.simple_expandable_list_item_1, new String[] {People.NAME}, // Name for group layouts new int[] {android.R.id.text1}, new String[] {People.NUMBER}, // AND CHANGE HERE new int[] {android.R.id.text1}); setListAdapter(mAdapter); } public class MyExpandableListAdapter extends SimpleCursorTreeAdapter { public MyExpandableListAdapter(Cursor cursor, Context context, int groupLayout, int childLayout, String[] groupFrom, int[] groupTo, String[] childrenFrom, int[] childrenTo) { super(context, cursor, groupLayout, groupFrom, groupTo, childLayout, childrenFrom, childrenTo); } @Override protected Cursor getChildrenCursor(Cursor groupCursor) { // Given the group, we return a cursor for all the children within that group // Return a cursor that points to this contact's phone numbers Uri.Builder builder = People.CONTENT_URI.buildUpon(); ContentUris.appendId(builder, groupCursor.getLong(mGroupIdColumnIndex)); builder.appendEncodedPath(People.Phones.CONTENT_DIRECTORY); Uri phoneNumbersUri = builder.build(); return managedQuery(phoneNumbersUri, mPhoneNumberProjection, null, null, null); } } @Override public boolean onChildClick(android.widget.ExpandableListView parent, View v, int groupPosition, int childPosition, long id) { AlertDialog dialog = new AlertDialog.Builder(ShowContacts.this) .setMessage(((TextView) v).getText().toString()) .setPositiveButton("OK", null).create(); dialog.show(); return true; } }

  • Swing: easiest way to align width of [dynamic][static][dynamic] components?
