Java/Swing+NetBeans 6.1. Keyboard event is not working

Java/Swing+NetBeans 6.1. Keyboard event is not working - java

I need to move a Label-control on the form.
I have created a "Java Desktop Application" in NetBeans 6.1.
I have added the following code:
But the label is not moving.
Why?

Take a look at the Swing tutorial.
1) Only components that have focus can receive KeyEvents. By default a JLabel is not focusable so it will never receive a KeyEvent. A better way to do this is to use Key Bindings. See the section from the Swing tutorial on Key Bindings.
2) If you fix 1, then the label might move, but it won't stay in its new position if the frame is resized, because the layout manager will be invoked and will reposition the label based on its rules.
Read the section from the Swing tutorial on Using Layout Managers. If you really need the label to be in a random position then you will need to use Absolute Positioning which is also discussed in the tutorial.

Java Netbeans For loop error: cannot find symbol class, <identifier> expected?

I'm making a hangman game and this is my current code:
//Declaring the array
String [] WordList = {"anonymous", "tolerate", "appreciation", "commissioner", "harm", "flexibility", "instructional", "scramble", "casino", "tumor"};
// Getting a random word for the game
int num = ((int)Math.ceil(Math.random()*(WordList.length)));
String word = WordList[num];
// The puzzle to be displayed for the user to guess
int letters = word.length();
String hiddenWord = "";
for (int i=0; i<letters; i++){
hiddenWord+="-";
}
At the for loop, I get an error saying 'illegal start of type, cannot find symbol: class i'. 'i' is supposed to be an integer, which I've already declared, so I'm not sure why it's asking for a class.
There's also another error saying, 'identifier expected' and that there's a missing >. As my < is meant to be used as comparison (and not as a declaration or identifier), I don't understand this error.
For clarification, I should add that this is a desktop application in netbeans. The code is located after the line:
public class HangmanGameView extends FrameView {
Most of the rest of my code will be located within the actionPerformed code for my buttons. I need to be able to access the word and hiddenWord variables from within the code for the buttons, which is why I've put them here. I'm not positive if that's the problem as of yet. I'm also not sure where to put the code otherwise; there is no main method as far as I can see.
Edit: I hadn't posted the complete code because this is all I've done for now; the rest is all auto-generated by NetBeans, and I thought it wouldn't be relevant. But here it is:

I moved my for loop to inside the start button code - leaving the initial declaration of the hiddenWord string at the beginning - and it's working fine now. Thanks for the help!

create JPanel after click the button /Java

I have a problem with my project. I would like to create new Panel in my Frame after click the button. Here's a part of a code:
private class ComponentListener implements ActionListener {
#Override
public void actionPerformed(ActionEvent e) {
if (e.getSource().equals(newGameItem))
{
System.out.println("dasda");
gamePanel = new GamePanel();
cont.add(gamePanel);
}
if (e.getSource().equals(stopItem)) {
gamePanel.stopGame();
}
}
}
GamePanel gamePanel;
Container cont = this.getContentPane();
When I click the button I see the text in console, also when I'm starting project already with this Panel everything is okay.
I guess this problem is simple but I can't figure out what's going on :( .
I see "dasda" so it means that method actionPerformed works correctly.
miniwolf where should I invoke repaint? In actionPerformed?

Okay, I found a solution. I should have added gamePanel.revalidate() in actionPerformed. Thanks for your help

I have to refresh this topic, cause I have a problem with change JPanel in JFrame form.
When I click the button I want to change a panel but I can't see it, but when I create JFrame (java class) and write code by myself everything's okay.
This is a code from JFrame (java class) made by me.
public class main extends JFrame
{
public main()
{
frameSettings();
this.getContentPane().add(panel1);
panel1.add(button);
panel1.setBackground(Color.red);
button.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent e)
{
gamePanel = new GamePanel();
container.add(gamePanel);
gamePanel.startGame();
gamePanel.revalidate();
gamePanel.requestFocus();
}
});
}
private void frameSettings() {
int szer = Toolkit.getDefaultToolkit().getScreenSize().width;
int wys = Toolkit.getDefaultToolkit().getScreenSize().height;
this.setTitle("Pong");
this.setSize(700, 600);
this.setResizable(false);
int szerRamki = this.getSize().width;
int wysRamki = this.getSize().height;
this.setDefaultCloseOperation(3);
this.setLocation((szer - szerRamki) / 2, (wys - wysRamki) / 2);
}
JPanel panel1 = new JPanel();
JButton button = new JButton();
GamePanel gamePanel;
Container container = this.getContentPane();

How to Change java Cardlayout from another separate class

Please I have been trying to switch CardLayout from another class (JPanel) which is one of the card on the CardLayout, I have search and made research about this for a very long time but found nothing helpful.
I have a CardLayout and two separate JPanels that I added to the CardLayout, now I want to be able to switch the cards after performing activities on the separate JPanel or separate class, so how do I switch the CardLayout from another class? my code below.
package myApp;
import java.awt.CardLayout;
public class TestmyCard extends javax.swing.JFrame {
/**
* Creates new form TestmyCard
*/
public TestmyCard() {
initComponents();
jPanel1.add(new FirstCard(),"card3");
jPanel1.add(new SecondCard(),"card4");
}
public void chgCard(String nwCard){
CardLayout cl = (CardLayout)(jPanel1.getLayout());
cl.show(jPanel1,nwCard);
}

In your provided code, you never added FirstCard and SecondCard, to the JPanel having layout set to CardLayout. Since what you writing is this :
jPanel1.add(jPanel2, "card2");
here jPanel2 is an instance of JPanel, as you have initialized this in your TestmyClass Class, as :
jPanel2 = new javax.swing.JPanel();
instead I guess what you should be writing is :
jPanel2 = new SecondCard(passPanelWithCardLayoutAsArgument); // So that you can manoeuvre around b/w other JPanels
Here is a small working example for your help :

private void clearFields()
{
Component components[] = centerPanel.getComponents();
for (Component comp : components)
{
if (comp instanceof JTextField)
{
JTextField tfield = (JTextField) comp;
tfield.setText("");
}
else if (comp instanceof JComboBox)
{
JComboBox cbox = (JComboBox) comp;
cbox.setSelectedIndex(0);
}
else if (comp instanceof JRadioButton)
{
JRadioButton rbut = (JRadioButton) comp;
rbut.setSelected(false);
}
}
}
And you will call this inside the actionPerformed() method of the Button, which will take you to the next Card.

Why Java jFrame setResizable() is failling to act?

This code is automatically generated by Netbean 6.8 GUI builder. The default application was not contained in a jFrame! It was in jPanel only which I didn't know how to make it none re-sizable. so I added a jFrame to contain all of them and although I set its setResizable(); to False...it still re-sizable! Here is the code:

I apologize for the long code, I wasn't sure which part might be important to this case and which one is not.
If you know what is the problem here, please let me know

You have a mistake in your code; my simple self-contained test program shows that setResizable(false) works just fine:
package com.businesslink.core.tst.ld.dct;
import java.awt.*;
import javax.swing.*;
public class SwgTestFrame1b
extends JFrame
{
public SwgTestFrame1b() {
super("SwgTestFrame1b");
setBackground(Color.white);
setResizable(false);
pack();
}
static public void main(String[] args) {
new SwgTestFrame1b().show();
}
}
A quick search of your code reveals nowhere that show or setVisible is invoked on mainFrame; it looks like you are only showing dialogs related to mainFrame. Now setResizable is only done on mainFrame, that will not impact any dialogs that are children of mainFrame. Nor will it affect the frame used by your FrameView.
PS, and just FTR, I absolutely abhor windows that are not resizable they are the mark of either an inadequate GUI toolkit or a lazy programmer.

The default application was not contained in a jFrame!
It was in jPanel only which I didn't know how to make it none re-sizable. so I added a jFrame
you shouldn't be creating an extra JFrame, your panel was already in a frame
You should have used something like this instead of creating a new frame:
getFrame().setResizeable(false);

fill code ((java.awt.Frame)root).setResizable(false); in application
class, exactly in method configureWindow.
(Application class is that class which instantiate View class. )
It should help
