Probably you are looking for SplitPane.oneTouchButtonOffset:
import java.awt.*;

d.put("SplitPane:SplitPaneDivider[Enabled+Vertical].foregroundPainter",
new Painter<JComponent>() {
#Override public void paint(Graphics2D g, JComponent c, int w, int h) {
/* empty */
}
});
JSplitPane splitPane = new JSplitPane();
splitPane.putClientProperty("Nimbus.Overrides", d);
splitPane.setLeftComponent(makePanel());
splitPane.setRightComponent(makePanel());
splitPane.setOneTouchExpandable(true);
JPanel p = new JPanel(new BorderLayout());
p.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
p.add(splitPane, BorderLayout.NORTH);
return p;
}
private static JComponent makePanel() {
JPanel p = new JPanel(new BorderLayout());
p.add(new JButton(), BorderLayout.WEST);
p.add(new JTextField("aaaaaaaa"));

f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);

I'm trying to make a program that uses Swing for the GUI, but the form that opens up when I run the code below is blank. I'm still able to get information regarding the objects that aren't seen, however (tested with getting btnLogin.getText()). Am I missing something, or am I doing something wrong?

import java.awt.event.ActionListener;

public class loginForm extends JFrame implements ActionListener{
public static void main(String[] args){
new loginForm();
}
public loginForm() {
System.out.println("Starting...");
pack();
initComponents();
System.out.println("Opened");
this.setVisible(true);
}
private void initComponents() {
loginForm = new JFrame();
lblUserID = new JLabel();
existingUserIDTextField = new JTextField();
lblPassword = new JLabel();
existingUserPasswordField = new JPasswordField();
btnLogin = new JButton();
btnLogin.addActionListener(this);
lblWelcome = new JLabel();
//======== loginForm ========
{
loginForm.setResizable(false);
loginForm.setTitle("Library Reservation System");
Container loginFormContentPane = loginForm.getContentPane();
//---- lblUserID ----
lblUserID.setText("User ID:");
lblUserID.setFont(new Font("Tahoma", Font.PLAIN, 16));
//---- lblPassword ----
lblPassword.setText("Password:");
lblPassword.setFont(new Font("Tahoma", Font.PLAIN, 16));

The frame containing the controls is never displayed.
loginForm.setVisible(true);
Instead of having an outer redundant frame class you could do
public class LoginFormApp extends JFrame {
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
LoginFormApp loginFormApp = new LoginFormApp();
loginFormApp.initComponents();
}
});
.....
}
where initComponents makes the loginForm visible as previously stated.
please help me i cant figure out to get my State ComboBox data to insert into my database here is my code. If anyone can help me id really appreciate it because it is driving me crazy that i cant figure it out.

You're shadowing you variables...
You declare statesComboBox as an instance field in your class...
private JComboBox statesComboBox;
But when you initalise it within your constructor, you declare it as a local variable...
JComboBox statesComboBox = new JComboBox(statesStrings);
This means you ActionListener is trying to use a null references (the instance field)
Ok, I have a program I am doing for class. I have to take the input form the text field, ad throw it into an overloaded constructor that takes a string as an argument. There are a few other things I have to do with constructors as well, so in my code you'll see some stuff that is outside of this question. also, I am not posting my methods because it's a big part of the homework, and those all work fine, (prior to my attempt at passing info to the constructor). What I would like to know is i there is a way to pass the text field info into the constructor, because I have been going at this for a couple hours now, but it's becoming plainly obvious that I don't understand this. If you just want to direct me to somewhere that I can learn how to do this I would appreciate it.

You'll need to create new instance of lab4 after you fill tex field value and click on submit. on click of submit you can do like this
this.setVisible(false);//Hide current instance
Lab4 test = new Lab4(this.jTextField1.getText()); // create new instance
test.setVisible(true); // set new instance visible
Don't forget to add following constructor:
public Lab4 (String value)
{
this.jTextField1.setText(value); // if you like to set value back to textbox
}
I am having problems in setting the GroupLayout as desired in Java.
My code is given below. The desired placement for components is:
++++++++++++++++++++++++++++++++++++++++++++++++++++
+LABEL_A caseStudyComboBox LABEL_B +
+LABEL_C TextfieldE BtnD +
++++++++++++++++++++++++++++++++++++++++++++++++++++
Instead of the above, the output is:
+++++++++++++++++++++++++++++++++++++++++++++++++++
+LABEL_A +
+ caseStudyCombBox +
+ LABEL_B +
+ LABEL_C IS LONGER THAN A: +
+ TextfieldE +
+ BtnD +
+++++++++++++++++++++++++++++++++++++++++++++++++++
Please suggest some remedy.
Thanks.

Looks like there is a bit of confusion with brackets when you set up horizontal and vertical groups. The controls fall out of the intended groups that you create.
Instead of
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup())
.addComponent(Label_A)
.addComponent(Label_C)
It should actually be:
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup()
.addComponent(Label_A)
.addComponent(Label_C))
In first case you're adding labels to the sequential group instead of the parallel group like in the second case.
Here is the result with the following slightly modified code:
layout.setHorizontalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(TRAILING)
.addComponent(Label_A, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
.addComponent(Label_C, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
.addGroup(layout.createParallelGroup(LEADING)
.addComponent(caseStudyComboBox, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
.addComponent(TextFieldE, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
.addGroup(layout.createParallelGroup(LEADING)
.addComponent(Label_B, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE)
.addComponent(BtnD, GroupLayout.DEFAULT_SIZE, GroupLayout.DEFAULT_SIZE, Short.MAX_VALUE))
);
layout.linkSize(SwingConstants.HORIZONTAL, Label_B, BtnD);
layout.setVerticalGroup(layout.createSequentialGroup()
.addGroup(layout.createParallelGroup(BASELINE)
.addComponent(Label_A)
.addComponent(caseStudyComboBox)
.addComponent(Label_B))
.addGroup(layout.createParallelGroup(LEADING)
.addComponent(Label_C)
.addComponent(TextFieldE)
.addComponent(BtnD))

I try to fix this problem but i am beginer in java scripting, where is the problem and how i can fix it ?
Tanks for helping, and recomand me please some good plugins for Eclipse.
That usually happens when the frame is not packed.
Try this:
launcher GUI = new launcher();
GUI.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
GUI.pack(); // <=========== PACK
GUI.setVisible(true);
Here is a nice tutorial that will get you started with Java frames.
