I have a jtextfield that I want to make invisible on start. I do not see an option for that in the design side under properties. I am a VB programmer and in VB there is an option under properties to make it visible or invisible.

I just make a watch (clock) application and i want when the windows start its also starts automatically except if it is closed by the user
just like widows clock widget.
I'm trying to make a button that will make a panel not visible and then will make another panel visible but i keep getting this error...
test.java:19: error: local variable panel is accessed from within inner class; needs to be declared final
panel.setVisible(false);

The problem is that I populate the table with autoincrement primary key. I don't want it to be visible. I have been googling for hours to find no solution. It seems that sql/mysql provides no solution by selecting all table columns except one. So I wonder, how I could overcome this problem. Here is some of my code:
public void tableChanged(TableModelEvent e) {
int row = e.getFirstRow();
int col = e.getColumn();
model = (MyTableModel) e.getSource();
String stulpPav = model.getColumnName(col);
Object data = model.getValueAt(row, col);
[Code] .....
The ID is used in
stmt.addBatch("update finance.fin set " + stulpPav + " = " + duom
+ " where ID = " + studId + ";");
I tried to omit ID from my SELECT statement, I tried to put Date as a first element in data[iEil][0] but neither options were successful. Data hasn't been changed in database. NOW, everything works fine, except I don't want ID column to be visible in my table.
I'm having a hard time finding out the way to make JTextField editable. In what circumstances it can be disabled to write? [even the text in the field can't be selected, not to mention being uneditable. I did the followings to make it editable.
1. In its Properties panel(frame or whatever), checked the "editable" item.
2. In the code I made it run the code below :
void makeFieldsEditable(Boolean flag) {
Left_Name_field.setEditable(flag);
Left_Name_field.setEnabled(flag);
...
}
Is it related with the properties of the control(JTextField)'s surrounding panel, or even the largest containing frame? Using Netbeans ....
This is a part of my program. When the user enters "Exam Schedule" in the JtextField and clicks the add button I want the link to change to a link that opens a local pdf file. And if the user enters "Academic Calendar" the Jlabel will be set to another link. So far this works fine but the problem is that if you erase the textfield and enter another value the link of the previous value will still be there.
public void actionPerformed (ActionEvent e){
if (e.getSource ==add) {
if (text.getText().equalsIgnoreCase("Exam Schedule")){
link1.setText(text.getText());
link1.setCursor(Cursor.getPredefinedCursor(Cursor.HAND_CURSOR));
[Code] ....
I already done a lot of work(user lists, server logging, private messages), but im there is few thing i still dont know how to really implement and, of course my current program is far from beign decent, so i decided to start asking questions(so far i was just experimenting just using knowledge from book and some info found on Java API).
1. How can i make JTextField to scroll down each time new message received and log is already full? i mean visible part of it, so you don't need to scroll it yourself...
2. Why sequencer doesn't play MIDI if it is launched not by main thread?
3. What is good way to do user list with avatars? atm, i'm using regular JList and listening to selected values to open dialogs.
4. What is a good ways to implement sounds in application, other than MIDI? i know that i should just google it, but anyway.

If u run it you can see that the JTextField (t1) is drawn on the panel along the line but it does so with a gray border. How do i eliminate that grey border and only draw the text field along the line and finally make the text field green after it reaches the end of line?
We are making a tic tac toe game for my CS120 class and I am having trouble figuring out how to make our X's and O's. Is there a way to make shapes besides making two lines for an X and an oval with a white smaller oval inside to make an O? We have only learned the basics so far in class (i.e. events, inheritance, client-supplier, etc.)
These are our instructions:
Write a controller that controls the game. There is one human player (the X player) and the computer player (the O player). The name of the class must be TicTacToeController. In a sense, the controller is the game since the controller will 1) create a TicTacToeModel 2) create a TicTacToeView and 3) create a TicTacToeButton (you must write this class following the design pattern covered in class lectures), a label, and text field such that when the button is pushed, the player moves into the cell selected by the text field. After every player move, the computer moves into a randomly selected empty cell. When the game is over, a text message must be displayed somewhere on the screen the gives the status of the game. While you are free to change the appearance of the controller, the basic elements must be provided (a view of the game, a button, and a text field to enter the cell). A sample screenshot is displayed below.And this is the code i have thus far:
[import java.awt.*;
import javax.swing.JFrame;
public class TicTacToeView extends Rectangle
public TicTacToeView(int x, int y, int w, int h) {
super(50,60,w,h);
this.setBackground(Color.red);
JFrame win = new JFrame("Tic Tac Toe");
win.setBounds(10,10,w+100, h+100);
win.setLayout(null);
win.setVisible(true);
win.setBackground(Color.gray);

So, I have a gameOver() method that should when oval goes out of bounds abort game but, as soon as I start the game it runs the gameOver method. I've been looking over it for a while trying different things. I think what stood out to me is removing the abort sequence the game runs mostly as it should after, popup is closed and that if I replace game.gameOver(); with ya = -1 the ball bounces off the wall.

public void gameOver(){
JOptionPane.showMessageDialog(this, "Game Over", "Game Over", JOptionPane.YES_NO_OPTION);
System.exit(ABORT);
