JTextField resizing after setting text that is longer than its initial size?

This is what the textfield looks like before clicking the check button:
This is what happens after clicking check. This only happens with a string that is longer than the textfield.
This is the code from netbeans:

import java.io.IOException;
import java.security.NoSuchAlgorithmException;
import java.util.logging.Level;
import java.util.logging.Logger;

You can handle it by using TextField and its method to set columns i.e. "setColumns(int numOfCols)"
import java.awt.FlowLayout;
import java.awt.Container;
import javax.swing.JFrame;
import javax.swing.JTextField;
public class TextFieldExample extends JFrame {
JFrame frame = new JFrame();
public TextFieldExample()
{
frame = new JFrame("Test");
Container container = frame.getContentPane();
JTextField fld1 = new JTextField("Java C++ C");
JTextField fld2 = new JTextField("");
JTextField fld3 = new JTextField("");
fld1.setColumns(5); //Now, it will not be resized.
fld2.setColumns(7); //Now, it will not be resized.
fld3.setColumns(9); //Now, it will not be resized.
container.setLayout(new FlowLayout());
container.add(fld1);
container.add(fld2);
container.add(fld3);
frame.setVisible(true);
frame.setSize(150,150);
}
public static void main(String[] args) {
TextFieldExample obj = new TextFieldExample();
}
}

How to set jLabel's ImageIcon from File instance's absolutePath

I want to add a photo from a chosen image File to a jPanel but, the following code doesn't seem to work :
private void browsePhotoButtonActionPerformed(java.awt.event.ActionEvent evt) {
JFileChooser fileChooser = new JFileChooser();
String[] fileSuffixes = ImageIO.getReaderFileSuffixes();
for(String fileSuffix:fileSuffixes){
FileFilter filter = new FileNameExtensionFilter(fileSuffix + " files", fileSuffix);
fileChooser.addChoosableFileFilter(filter);
}
int selection = fileChooser.showOpenDialog(EmployeeInternalFrame.this);
if(selection == JFileChooser.APPROVE_OPTION){
File fileBeingOpened = fileChooser.getSelectedFile();
setPhotoFile(fileBeingOpened);
setImageURL(getPhotoFile().getAbsolutePath());
photoPanel.removeAll();
Icon icon = new ImageIcon(getImageURL());
JLabel label = new JLabel(icon, SwingConstants.LEFT);
photoPanel.add(label);
photoPanel.repaint();
}
}
Which part am I missing ? Thank you for all of your help.

The documentation of ImageIcon(String filename) states that:
Creates an ImageIcon from the specified file. The image will be preloaded by using MediaTracker to monitor the loading state of the image. The specified String can be a file name or a file path. When specifying a path, use the Internet-standard forward-slash ("/") as a separator. (The string is converted to an URL, so the forward-slash works on all systems.) For example, specify:
new ImageIcon("images/myImage.gif")
The description is initialized to the filename string.
So, what I think your problem is with the path that you have given as parameters which has \ in the path.

I "think" the problem is with the use of GroupLayout, it's generally a
pain in the ... Code ... Personally, I'd use a different layout, even
with the form editor and add a place holder label for the phot, which
you can use to set the icon – MadProgrammer yesterday
I changed the panel's layout into Card Layout, and it's fine now, thank you everyone :)

NetBeans Java Project Won't Display GUI Window Despite No Error

I am trying to build a java project using Netbeans IDE 7.1.
I somehow can't see or view the GUI window that I have created.
Please kindly advise.
In my class:

the MainCalculator is the GUI window I would like to run. It somehow wont't display.
There is NO error message in my console tough..
Here is the MainCalculator code:

Any advise is appreciated.

The MainCalculator class is a JPanel. A JPanel can't just be displayed like that, it has to be part of a Window. Add it to a JFrame and call setVisible(true) on the JFrame.
Also, #npinti's advice is very good: execute GUI-related code in the EDT thread.

The issue is most likely in this section:
public static void main(String[] args) {
MainCalculator calc = new MainCalculator();
calc.setVisible(true);
}
You need to make any GUI related tasks within the Event Dispatcher Thread (EDT).
Try something like so:
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable()
{
#Override
public void run()
{
MainCalculator calc = new MainCalculator();
calc.setVisible(true);
}
});
}

Losing JDialog title when hiding panel (Java)

EDIT:
Of course I find an answer 2 min after I post a question.
How to completely remove an icon from JDialog?
But follow-up; anyone knows the way to make consistent icon state when changing resizable property?
PS. I can't answer my own question for 8 more hours.
ORIGINAL QUESTION:
To put it short, here is an stripped down example code which has a problem.
When I click on "Details" (WinXP x32 java 1.6) jPanel2 changes visibility state and together with jPanel2 for some reason the dialog icon is removed. Quite curious.
Anyone knows why the icon is hidden together with JPanel?
Code is generated by NetBeans 7.1, only slightly adapted to be self-contained.
Thanks in advance for help!

There is too much code there to look at 90% of it is NOT related to adding data in a combo box. You have a dozen other components which clutter the code so we can't see what actually happening with the comobo box.
It you really need help then post a SSCCE.
That is, create a simple frame and load hard coded data into the combo box.
Then create a simple program to read data from the database and use System.out.println(...) to display each value.
Once you've mastered the two basic steps, then put the two programs together to load a combobox dynamically from a database.
Finally add the rest of you components to the frame.
Break you problem down into small, manageable steps and you will be able to debug it easier.

A few points:
Wading through your code, I don't see a call to initData being made anywhere. Without that call, you wont call your database code. Without the database call, you wont get the data.
JComboBox does not have a setModel method that takes an array. You can wrap your array in a DefaultComboBoxModel and set that on the model.
It is good to keep in mind that blocking calls like database access should not be made in the AWT painting thread, and neither should calls that update the GUI be made outside of the AWT thread. You should look into creating your GUI and grabbing your data in separate threads, and making use of SwingUtlities.invokeLater or similar tools to update your GUI.
