In the above example, I have created the three panels, and I have assigned all of them different heights. But all the three panels are taking more than assigned heights.
How to assign the different heights to different panels ?
Firstly: Instead of setSize() better use setPreferredSize() for your Panels
tfpanel.setPreferredSize(new Dimension(200,40));
panel2.setPreferredSize(new Dimension(200,60));
buttonpanel.setPreferredSize(new Dimension(200,120));
Secondly don't use GridLayout for your mainpanel because it makes all its components of same size. You could simply leave this line out
//mainpanel.setLayout(new GridLayout(0,1));

I have panel with 2 buttons in BoxLayout. What i want is to add vertical space between the buttons.
Here is my code:
frame = new JFrame("FreshPos baza podataka");
frame.setExtendedState(JFrame.MAXIMIZED_BOTH);
JPanel panel = new JPanel();
panel.setBounds(new Rectangle(0, 5, 0, 0));
panel.setAlignmentY(Component.BOTTOM_ALIGNMENT);
frame.getContentPane().add(panel, BorderLayout.WEST);
panel.setLayout(new BoxLayout(panel, BoxLayout.Y_AXIS));
panel.setBorder( BorderFactory.createEmptyBorder(10,10,10,10) );
JButton btnNewButton_1 = new JButton("New button");
panel.add(btnNewButton_1);
JButton btnNewButton_2 = new JButton("New button");
panel.add(btnNewButton_2);
Add an invisible vertical component to the panel in between the two buttons:
JButton btnNewButton_1 = new JButton("New button");
panel.add(btnNewButton_1);
panel.add(Box.createVerticalStrut(50));
JButton btnNewButton_2 = new JButton("New button");
panel.add(btnNewButton_2);
I need to make a program that ends up looking like this:
My code so far is what's posted and I can't seem to wrap my head around how to make this look exactly like the image I provided. I just don't really know what else I can do, I've tried looking around for solutions, but I can't manage to combine that information with this to make it all work together.
So, I hope somebody else can help me here, it'd be greatly appreciated! :D

So this is what I have so far in what I think an answer suggested me to do. Like I said I can't see my panel4 when I have button 10 on there as well, I'm sure it's something I'm just not seeing but still.

I'd make that with 3 grid layouts and a border layout. E.G.
GridLayout for left/right sections (each section a panel)
GridLayout for buttons 1-6
BorderLayout for buttons 7-10 + panel in CENTER for..
GridLayout for buttons 11-18

I'm writing a program that does the following:
Create a frame and set its layout to FlowLayout.
* Create two panels and add them to the frame.
* Each panel contains three buttons. The panel uses FlowLayout. Here is my code:
import java.awt.*;
import javax.swing.JFrame;
import javax.swing.JButton;
import javax.swing.JPanel;
class Flow{
public static void main(String[] args){
JFrame f = new JFrame("Testing out these JPanels");
f.setSize(400, 100);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLocationRelativeTo(null);
f.setVisible(true);
f.setLayout(new FlowLayout());
JButton b = new JButton("button 1");
JButton butt = new JButton("button 2");
JButton bug = new JButton("button 3");
JButton button = new JButton("button 4");
JButton button5 = new JButton("button 5");
JButton button6 = new JButton("button 6");
JPanel p = new JPanel();
p.setLayout(new FlowLayout());
p.setVisible(true);
p.setSize(200, 100);
JPanel pnl = new JPanel();
pnl.setLayout(new FlowLayout());
pnl.setSize(200,100);
p.add(b);
p.add(butt);
p.add(bug);
pnl.add(button5);
pnl.add(button);
pnl.add(button6);
f.add(button5);
}
}
When I run the program, the frame shows up but not my buttons or panels. Can someone please explain what I'm doing wrong?
You should add the JPanel p and pnl to JFrame
// f.add(button5); Comment this line button5 is already added to pnl
// Now add the two panel with JFrame.
f.add(p);
f.add(pnl);
And, for proper layout manager, go through this tutorial.
You need to add you JPanel to your JFrame
f.getcontentpane().add(p);
f.getcontentpane().add(pnl);
and then call setVisible() on the frame.
f.setVisible(true);
It is not showing because you set the visibility of frame to true before you add the buttons, therefore it only rendered the frame without buttons and by the time you re-size the JFrame it will show the buttons because it is rendered again.
solution:
set the visibility of the frame after you add the buttons
JFrame f = new JFrame("Testing out these JPanels");
f.setSize(400, 100);
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
f.setLocationRelativeTo(null);
f.setLayout(new FlowLayout());
JButton b = new JButton("button 1");
JButton butt = new JButton("button 2");
JButton bug = new JButton("button 3");
JButton button = new JButton("button 4");
JButton button5 = new JButton("button 5");
JButton button6 = new JButton("button 6");
JPanel p = new JPanel();
p.setLayout(new FlowLayout());
p.setVisible(true);
p.setSize(200, 100);
JPanel pnl = new JPanel();
pnl.setLayout(new FlowLayout());
pnl.setSize(200,100);
p.add(b);
p.add(butt);
p.add(bug);
pnl.add(button5);
pnl.add(button);
pnl.add(button6);
f.add(button5);
f.setVisible(true); //relocated here
You have created the panels, but have forgot to add the panels in that frame, exactly the same way you have added the "button 5"
try including this in code:
f.add(p);
f.add(pnl);
class Frame extends JFrame{
public Frame()
{
JFrame jf= new JFrame("Student Admission");
jf.setLayout(new GridLayout(5,1));
JPanel jpn= new JPanel();
JPanel enr= new JPanel();
enr.setLayout(new FlowLayout(FlowLayout.LEFT));
JLabel enrno= new JLabel("Enrollment Number",JLabel.LEFT);
JTextField enrnoinput=new JTextField(3);
enr.add(enrno);
enr.add(enrnoinput);
jf.add(enr);
JLabel name= new JLabel("Student's Name",JLabel.LEFT);
JTextField nameinput=new JTextField(60);
jpn.add(name);
jpn.add(nameinput);
jf.add(jpn);
JPanel jpfn= new JPanel();
JLabel fname= new JLabel("Fathers's Name",JLabel.LEFT);
JTextField fnameinput=new JTextField(60);
jpfn.add(fname);
jpfn.add(fnameinput);
jf.add(jpfn);
JPanel hscp= new JPanel();
hscp.setLayout(new FlowLayout(FlowLayout.LEFT));
JLabel hscper= new JLabel("Hsc Percentage",JLabel.LEFT);
JTextField hscperinput=new JTextField(3);
hscp.add(hscper);
hscp.add(hscperinput);
jf.add(hscp);
JPanel sscp= new JPanel();
sscp.setLayout(new FlowLayout(FlowLayout.LEFT));
JLabel sscper= new JLabel("Ssc Percentage",JLabel.LEFT);
JTextField sscperinput=new JTextField(3);
sscp.add(sscper);
sscp.add(sscperinput);
jf.add(sscp);
//After Adding this panel the frame's structure get disturbed
JPanel buttonPanel= new JPanel();
JButton save= new JButton("Save");
JButton cancel= new JButton("Cancel");
buttonPanel.add(save);
buttonPanel.add(cancel);
jf.add(buttonPanel);
jf.setResizable(false);
jf.pack();
jf.setVisible(true);
jf.setDefaultCloseOperation(EXIT_ON_CLOSE);
}
}
Before Adding buttonPanel
After adding buttonPanel
I want to add button panel in the Middle-Bottom of the frame how can I do that?
Your grid layout only accounts for 5 components, so it's screwing up everything when you use 6. Add the buttonPanel to the sscp panel and then add the sscp panel to the overall Frame.
JPanel sscp= new JPanel();
sscp.setLayout(new FlowLayout(FlowLayout.LEFT));
JLabel sscper= new JLabel("Ssc Percentage",JLabel.LEFT);
JTextField sscperinput=new JTextField(3);
sscp.add(sscper);
sscp.add(sscperinput);
JPanel buttonPanel= new JPanel();
JButton save= new JButton("Save");
JButton cancel= new JButton("Cancel");
buttonPanel.add(save);
buttonPanel.add(cancel);
//change here
sscp.add(buttonPanel);
jf.add(sscp);
I want to align JButton instances vertically. Can you please suggest a way to do so?
