I have a simple GUI and I just want to have some text fields stacked on top of each other, with each box being a JPanel. I'm currently using FlowLayout for both the JFrame and JPanel but it changes from being stacked to being in a row when I maximize. Ideally I'd like the text fields to stay in the center of the window even if its maximized. I was looking at using a BoxLayout but was having some trouble getting that to work.
public static Component textbox(String x){
JPanel panel = new JPanel(new FlowLayout(5,5,5));
JLabel lbltAm= new JLabel(x);
JTextField tftAm = new JTextField(10);
lbltAm.setFont(new Font("Serif", Font.PLAIN, 14));
lbltAm.setForeground(Color.white);
panel.add(lbltAm, BorderLayout.NORTH);
panel.add(tftAm, BorderLayout.CENTER);
panel.setBackground(Color.DARK_GRAY);
Border lowerbevel = BorderFactory.createBevelBorder(BevelBorder.LOWERED);
panel.setBorder(lowerbevel);
return panel;
}
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new JFrame("Tip Calculator");
//Add Textbox
frame.setLayout(new BoxLayout(frame, BoxLayout.Y_AXIS));
String Label = "Tip Calculator";
JLabel header = new JLabel(Label);
header.setFont(new Font("Serif", Font.BOLD, 18));
frame.add(header);
frame.add(textbox("Total"));
frame.add(textbox("Tip %"));
frame.add(textbox("People"));
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().setBackground(Color.gray);
frame.setPreferredSize(new Dimension(300, 400));
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
It's a matter of opinion, but for flexibility, I prefer to use GridBagLayout

}
});
}
public class TestPane extends JPanel {
public TestPane() {
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = GridBagConstraints.REMAINDER;
add(textbox("Total"), gbc);
add(textbox("Tip %"), gbc);
add(textbox("People"), gbc);
}
public Component textbox(String x) {
JPanel panel = new JPanel(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = GridBagConstraints.REMAINDER;
gbc.insets = new Insets(5, 5, 5, 5);
JLabel lbltAm = new JLabel(x);
JTextField tftAm = new JTextField(10);
lbltAm.setFont(new Font("Serif", Font.PLAIN, 14));
lbltAm.setForeground(Color.white);
panel.add(lbltAm, gbc);
panel.add(tftAm, gbc);
panel.setBackground(Color.DARK_GRAY);
Border lowerbevel = BorderFactory.createBevelBorder(BevelBorder.LOWERED);
panel.setBorder(lowerbevel);
return panel;
}
}
}
Or if your wanted the "boxes" to occupy the whole area when expanded, you could use something like...
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridwidth = GridBagConstraints.REMAINDER;
gbc.weightx = 1;
gbc.weighty = 1;
gbc.fill = GridBagConstraints.BOTH;
add(textbox("Total"), gbc);
add(textbox("Tip %"), gbc);
add(textbox("People"), gbc);
Which results in something like...
Have a look at Laying Out Components Within a Container and How to Use GridBagLayout for more details
Firstly, I don't know why you're adding components to the JPanel with a method that is for BorderLayout after you've set the layout of panel as FlowLayout.
If you want to keep the components centered at all times (even if the screen is maximized), FlowLayout is probably not the best option for you to work with, as FlowLayout continues to position components horizontally until they fill the width of the frame (one row) and then, it begins the next row. Therefore, if the screen size is maximized, there will be more components per row and they won't be stacked. I would suggest using a GridLayout with one column like so:
frame.setLayout(new GridLayout(3 *(number of rows/components)*, 1));
You can do the same with the JPanel. After that, set the horizontal alignment of each component as centered like so:
component.setHorizontalAlignment(componentName.CENTER);
Hope this helps!
Try to use GridLayout instead of BoxLayout in createAndShowGUI.
frame.setLayout(new GridLayout(4,1));

Let's say a JFrame contains just 1 JPanel. This JPanel is divided into 2 JPanels occupying accordingly 0.75 and 0.25 of the JFrame height. I want all of this to be resizable along with the window size.
I have no idea how to do this in Java.
I'm a newbie to Java. I've read a bit about layouts, but all I can see is how to set preferred size in constructor (ceasing to resize when this number is reached) or some fixed sizes obtained through setting borders.
JFrame with a BorderLayout, onto that, add a JPanel with a GridBagLayout. Add your other two panels onto this.

I'm having trouble positioning elements in a JPanel. I tried using GridBagLayout but that doesn't seem to make any of the parts of the panel GUI components move. What should I do?
panel.add(Label);
panel.add(TextField);
panel.add(Label);
panel.add(JChooser);
Nothing seems to help move these GUI elements. They just act like they are in a FlowLayout. What should I do? I'm using a CardLayout for another panel (that panel holds other panels like this one in it), but this panel, I need to align them to the left.
The Label and TextField need to be on the same line, but the Label and JChooser need to be on a different line.
Example:
SomeLabel : [ TextField ]
SomeLabel : [Chooser]
I hope I explained well enough.

GridBagLayout requires constraints, which define how and where a component will be positioned within the virtual grid maintained by it

import java.awt.Insets;
import javax.swing.JComboBox;

});
}
public class TestPane extends JPanel {
public TestPane() {
setLayout(new GridBagLayout());
GridBagConstraints gbc = new GridBagConstraints();
gbc.gridx = 0;
gbc.gridy = 0;
gbc.anchor = GridBagConstraints.WEST;
gbc.insets = new Insets(4, 4, 4, 4);
add(new JLabel("SomeLabel :"), gbc);
gbc.gridy++;
add(new JLabel("SomeLabel :"), gbc);
gbc.gridx = 1;
gbc.gridy = 0;
gbc.anchor = GridBagConstraints.EAST;
gbc.fill = GridBagConstraints.BOTH;
add(new JTextField(10), gbc);
gbc.gridy++;
add(new JComboBox(new Object[]{"Puppies", "Kittens"}), gbc);
}
}
}
To set elements in JPanel use one of LayoutManagers.
If you want to set components free from location.
then use following to remove layout.
panel.setLayout(null);
After this you can call setBounds method to set bounds for component, or setLocation .
comp.setLocation(int left, int top);
comp.setBounds(int left, int top, int width, int height);
I have encountered a problem whilst working the JFrame's, and JButtons. I am trying to center my JButton, however when I do so, it covers almost the entire screen. Any idea's on what's causing this?
Here is a picture on how it looks :
And here is my code :

public characterSelector(){

cselectorButtons = new JFrame("SupremeSoccer");
logo = new JLabel(new ImageIcon(ImageIO.read(this.getClass().getResource("/resources/Character_Selector_Image.png"))));
characterName = new JLabel("<Character Name>");
characterName.setFont(new Font(characterName.getFont().getName(),
Font.HANGING_BASELINE, 50));
/*
Buttons
*/
male = new JButton("Male");
////******************////
//// END OF BUTTONS ////

cselectorButtons.add(logo);
cselectorButtons.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
cselectorButtons.setContentPane(label);
cselectorButtons.setLayout(new BorderLayout());
cselectorButtons.add(logo, BorderLayout.NORTH);
cselectorButtons.add(male, BorderLayout.CENTER);
cselectorButtons.pack();
cselectorButtons.setLocationRelativeTo(null);
cselectorButtons.setVisible(true);
} catch (IOException exp) {
exp.printStackTrace();
}
}
}
Thanks again.
Any idea's on what's causing this?
This is the default behaviour of BorderLayout. The component at the CENTER position will occupy the maximum amount of space the is available from the parent component, when the other (NORTH, SOUTH, EAST, WEST) positions have been taken into account
Depending on what you are trying to achieve you might consider creating another JPanel (set it's opaque state to false so it's transparent) and use something like GridLayout or GridBagLayout instead.
Take a look at A Visual Guide to Layout Managers for some more ideas
Updated
So based on your linked code, I changed
part2 = new JPanel();
to
part2 = new JPanel(new java.awt.GridBagLayout());
And got...
Updated with additional example
Start by breaking down your requirements into individual containers and focus on the layout requirements for each individual, then build them all back into a single container.
This will make changing them later much easier and also make controlling them much easier...

Use a BoxLayout or (easier) GridBagLayout for the bottom area, as seen in this answer.

I see two problems in your current layout:
You put your login panel in the center of the parent BorderLayout (so your panel gets stretched to the size of its container)
You have nothing in your GridBagLayout that will "push" your components to the top and to the left.
There are several options here:
You nest your login panel into several panels (for example using BorderLayout, once with the constraint NORTH and the second time with the constraint WEST).
Add your loginPanel to the WEST and you add a "filler" component to the bottom of the GridBagLayout in order to push the other components to the top.
Here is a demo of the second solution:

I also took the liberty of:
Rename your variables to meaningful names (it makes your code easier to read for others)
Replace your custom background image panel with a JLabel
Move your buttons to a nested panel with another LayoutManager
Take another background image since I don't have yours.
If you want it explicitly to be in the top left I'd rather use the NORTHWEST anchor. FIRST_LINE_END for text flowing left to right would also put the text on the right corner and the other way around for right to left.
Also, switch gridx and gridy to start at 0 instead of 1. And increment from as needed from there.
So for example:
g2.anchor=GridBagConstraints.NORTHWEST;
g2.gridx=0;
g2.gridy=0;
p2.add(l2,g2);
g2.gridx=1;
g2.gridy=0;
p2.add(t1,g2);
/*And so on for the rest of the block*/
Use FIRST_LINE_START as anchor value.
g2.anchor=GridBagConstraints.FIRST_LINE_START;
Trying to build out a GUI for my game but no matter what layout I work with I can't get the nest of panels to do what I like

To be honest, I tried following your code, but got lost, so I re-wrote it...
Basically, you relying on setSize which is going to be ignored and changed by the layout managers as they see fit.
This example uses GridBagLayout and weighty to adjust the space allocated to the top (2D/3D) views and the bottom views, but you should also take a look at overriding the getPreferredSize of the final components, to provide better hints to the layout managers.
