corrected source:DefaultTableCellRenderer renderer_right = new DefaultTableCellRenderer(); renderer_right.setHorizontalAlignment(JLabel.RIGHT); //tb.setDefaultRenderer(tb.getColumnClass(0),renderer_right); tb.getColumn(tb.getColumnName(0)).setCellRenderer(renderer_right); DefaultTableCellRenderer renderer_center = new DefaultTableCellRenderer(); renderer_center.setHorizontalAlignment(JLabel.CENTER); for (int i=1; i<tb.getColumnCount();i++) { //tb.setDefaultRenderer(tb.getColumnClass(i), renderer_center); tb.getColumn(tb.getColumnName(i)).setCellRenderer(renderer_center); }Explanation: tb.setDefaultRenderer(tb.getColumnClass(0),renderer_right); sets renderer for specified column class (not column index!) You only take column class from column 0, next in for-loop class is tb.getColumnClass(i) but all column classes are the same so the same renderer will be used everywhere. Check what will happen when You put tb.setDefaultRenderer(tb.getColumnClass(0),renderer_right); after for-loop.>

first idea I've got:
in the last sourcecode attached, in line 7 You have method called rawr() where You add components to JFrame but You never invoke this method so it's never added to JFrame - am I right?

Shouldn't You use getValue() instead of getText() ?? It always returns valid value and getText may not... also use JFormattedTextField(Object value) constructor to create first valid value and setFormatterFactory(new javax.swing.text.DefaultFormatterFactory(new javax.swing.text.NumberFormatter(new java.text.DecimalFormat("#0")))); to get integers only.

how do i call the buttonActionPerformed method directly within this Keypressed method??

//to invoke actionPerformed try this yourButton.doClick(); //or yourButton.fireActionPerformed(new ActionEvent(/*create appropriate event*/)); //but I am not sure if I understood what You want.

Hello,

I am using NetBeans 6.8 and got some problems when I want to add something to binded data. I have created a JTable (myListTable) that is binded with LinkedList<MyItem> (myList). I have created JButton (addRowButton) that should add new MyItem to myList which (probably) should add a row with that item to myListTable... and this is where the problem occurs. Firstly I have tried this:@Action public void addRow() { myList.add(new MyItem(myList.size(), "Random num: "+Math.random())); }but got error java.lang.IndexOutOfBoundsException and I could not identify what causes it (probably it is because I have increased myList but myListTable does not have enough rows). So I made a small workaround:@Action public void addRow() { org.jdesktop.beansbinding.Binding b = bindingGroup.getBinding("list2table"); //list2table is name of binding b.unbind(); myList.add(new MyItem(myList.size(), "Random num: "+Math.random())); b.bind(); }but now after adding a row, column name changes (don't know why it happens?!)

This is how MyItem is defined:public class MyItem { private int id; private String content; //in table column name is "Random number" // (constructor & getters & setters here) }Questions:
1. I would like to know is it possible to add data to bean that is binded to component? What is correct way of doing this?
2. Is my way of biniding correct? (I made it with tutorial from official netbeans site)

NetBeans zipped project with isolated problem: http://www.fdasfdas.prv.pl/JTableBindProblem.zip

@edit
Found solution on my own here:
http://swinglabs.org/docs/presentations/2007/DesktopMatters/beans-binding-talk.pdf

I know You've solved the problem but.. isn't this easier:try { Desktop.getDesktop().open(new File("D:\\prog file\\090422.xls")); } catch (IOException e) {e.printStackTrace();}result is the same and You don't have to "play" with cmd here...

check this (taken from my old project) - it should load the font register.ttf, string "bin/register.ttf" is path inside jar file:Font registerFont = Font.createFont(Font.TRUETYPE_FONT, getClass().getClassLoader().getResource("bin/register.ttf").openStream());

elo,

Why don't You use only visibility of JInternalFrame to change it's state (closed/opened)?
After line 4 where You create new JIF just put this:claimSelection.setDefaultCloseOperation(JInternalFrame.HIDE_ON_CLOSE);if the user will click the X to close the JIF it will become hidden only (not disposed). And if You want it to apper on desktop just call claimSelection.setVisible(true);

minimize frame1 = minimize frame2:import java.awt.event.WindowEvent; import java.awt.event.WindowStateListener; import javax.swing.JFrame; public class RunMe { public static void main(String[] args) { final JFrame frame1 = new JFrame("frame1"); frame1.setBounds(10, 10, 150, 50); final JFrame frame2 = new JFrame("frame2"); frame2.setBounds(170, 10, 150, 50); WindowStateListener wsl = new WindowStateListener() { @Override public void windowStateChanged(WindowEvent arg0) { frame2.setState(((JFrame)arg0.getSource()).getState()); } }; frame1.addWindowStateListener(wsl); frame1.setVisible(true); frame2.setVisible(true); } }is this what You wanted to achieve?

Thank You for fast reply Maneesh it works

Hello,

I'd like to set JMenuItem's height to specified size (width should be auto set to see full text). Method setMinimumSize(X, Y) is ignored (anyone know why?). Method setPreferredSize(X, Y) sets size exactly to X, Y even if it cuts the text of JMenuItem. I've been also tring to work out something with menu.getPopupMenu() and it's layout but without results.. What I'd like to get, is JMenuItem with height of Y and width set to largest JMenu's item (to see whole text; check image at bottom of this post).

I believe this is very easy to do.. but have no ideas how.. I appreciate any suggestions.

Sample code to see the problem:import java.awt.Dimension; import java.awt.FlowLayout; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; public class RunMe extends JFrame { public RunMe() { this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); this.setBounds(10, 10, 800, 600); JMenuBar menuBar = new JMenuBar(); JMenu menu = new JMenu("testMenu"); menuBar.add(menu); //menu.getPopupMenu().setMinimumSize(new Dimension(100, 50)); //menu.getPopupMenu().setPreferredSize(new Dimension(100, 50)); //menu.getPopupMenu().setMaximumSize(new Dimension(999, 50)); //menu.getPopupMenu().setLayout(new FlowLayout()); JMenuItem menuItem = new JMenuItem("testMenuItem"); menuItem.setMinimumSize(new Dimension(100, 50)); menuItem.setPreferredSize(new Dimension(100, 50)); //menuItem.setMaximumSize(new Dimension(999, 50)); menu.add(menuItem); JMenuItem veryLongMenuItem = new JMenuItem("long text in menu item"); veryLongMenuItem.setMinimumSize(new Dimension(100, 50)); veryLongMenuItem.setPreferredSize(new Dimension(100, 50)); //veryLongMenuItem.setMaximumSize(new Dimension(999, 50)); menu.add(veryLongMenuItem); this.setJMenuBar(menuBar); this.setVisible(true); } public static void main(String[] args) { new RunMe(); } }
this is what I've got (text is cut):




this is what I'd like to get (created with graphic editor!):

OK, I understand that You don't want scrolbars but I still think that JScrollPane is the best solution for this. You can hide scrollbars withyourScrollPane.setHorizontalScrollBarPolicy(ScrollPaneConstants.HORIZONTAL_SCROLLBAR_NEVER) yourScrollPane.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_NEVER)and there won't be any scrollbar. After this You should make some kind of connection between Your drag&drop function and viewport of scrollpane.. and again I post this link

I think that this example can help You: LINK
When You put MapPane on JScrollPane You should be able to see whole image (with scrolling). Then You can implement dragging to it and hide scrollbars.

I think that these may be helpfull:

Sylvain Prodo wrote:(...)there still a little problem: the big picture is cut when I move it... have you got any idea about the way i can correct that?

I would try putting JPanel on which You are painting inside JScrollPane... but I'm not sure about this... check this example - it should help You with this problem.

Sylvain Prodo wrote:what means -Xms128m -Xmx512m in fact?

I won't tell You - Campbell Ritchie gave You the link to documentation, You don't have to read everything... just options You want to use: -Xmsn and -Xmxn

Sylvain Prodo wrote:and is this the only one way to do that with the .bat ?

No.. I hope that it is posible to pass argument to VM inside jar-file (in manifest file?) but I have too small knowledge on this topic
Try to find with google how to pass VM arguments under NetBeans
@edit: (in case You couldn't find it for NetBeans: RightClickOnProject -> SetConfiguration -> Customize... -> VM Options)
