I am trying to make a 3 column layout, in each column i want to be able to absolute position labels and textboxes.
Problem is that my label (jLabel2) never even gets displayed..
Here is my code:
/**
* Top JPanel (Top)
*/
JPanel pnlTop = new JPanel();
pnlTop.setBackground(new java.awt.Color(223, 223, 217));
pnlTop.setBorder(BorderFactory.createMatteBorder(0, 0, 1, 0, new java.awt.Color(173, 173, 166)));
c.gridx = 0;
c.gridy = 0;
c.gridwidth = 5; // five rows
c.gridheight = 1; // one column
c.fill = GridBagConstraints.BOTH;
//c.weighty = 0.04;
add(pnlTop, c);
/**
* Top JPanel Content (Here is where i want to put absolute content)
*/
JPanel pnlTopContent = new JPanel();
pnlTopContent.setLayout(null);
jLabel2.setFont(new java.awt.Font("Lucida Grande", 1, 16)); // NOI18N
jLabel2.setText("Hello");
jLabel2.setLocation(150, 50);
pnlTopContent.add(jLabel2);
pnlTop.add(pnlTopContent);
Any ideas what i am doing wrong?
Then its showing but not in the right place
What does "right place" mean to you? Why are you even adding you label to a second panel? Why not just add the label directly to the pnlTopContent?
GridBagLayout has a constraint that allows you to position the component right/left/center of the column. Read the section from the Swing tutorial on How to Use GridBagLayout. You might want to start with the anchor constraint.
Use layout manager for pnlTopContent. Which one is right depends on what you want. Even the default FlowLayout might work. If you want to center the label, you can for example use FlowLayout with center alignment:
pnlTopContent.setLayout(new FlowLayout(FlowLayout.CENTER));

I am trying to make a game which looks something like this:
I'm trying to find the most suitable layout design for this. I tried using gridbag layout but there are some components which are not added correctly. This is my code:
//Gridbag for the whole frame
GridBagLayout gridbag = new GridBagLayout();
GridBagConstraints constraints = new GridBagConstraints();
this.setLayout(gridbag);
constraints.fill = GridBagConstraints.BOTH;
constraints.insets = new Insets(10, 10, 10, 10);
constraints.weightx = 0.5;
//Top left panel
pnlHP = new JPanel();
pnlHP.setBackground(new Color (75, 55, 28));
gridbag.setConstraints(pnlHP, constraints);
this.add(pnlHP);
GridBagLayout gridbagHP = new GridBagLayout();
GridBagConstraints constraintsHP = new GridBagConstraints();
pnlHP.setLayout(gridbagHP);
constraintsHP.fill = GridBagConstraints.BOTH;
constraintsHP.insets = new Insets(10, 10, 10, 10);
constraintsHP.weightx = 1.0;
lblHPTitle = new JLabel();
lblHPTitle.setText("HP");
lblHPTitle.setForeground(Color.WHITE);
lblHPTitle.setFont(new Font("Arial", Font.PLAIN, 60));
gridbagHP.setConstraints(lblHPTitle, constraintsHP);
pnlHP.add(lblHPTitle);
lblHP = new JLabel();
lblHP.setText("asdf");
lblHP.setForeground(Color.WHITE);
lblHP.setFont(new Font("Arial", Font.PLAIN, 20));
lblHP.setHorizontalAlignment(SwingConstants.RIGHT);
constraintsHP.gridwidth = GridBagConstraints.REMAINDER;
gridbagHP.setConstraints(lblHP, constraintsHP);
pnlHP.add(lblHP);
pgbHP = new JProgressBar();
pgbHP.setBackground(new Color (75, 55, 28));
pgbHP.setValue(25);
constraintsHP.weightx = 0.0;
gridbagHP.setConstraints(pgbHP, constraintsHP);
pnlHP.add(pgbHP);
//Top center part
btnGo = new JButton();
btnGo.setBackground(new Color (126, 72, 28));
btnGo.setText("Start Adventure!");
btnGo.setForeground(Color.WHITE);
btnGo.setFont(new Font("Arial", Font.PLAIN, 42));
gridbag.setConstraints(btnGo, constraints);
this.add(btnGo);
//Top right panel
pnlMPSP = new JPanel();
pnlMPSP.setBackground(new Color (75, 55, 28));
constraints.gridwidth = GridBagConstraints.REMAINDER;
gridbag.setConstraints(pnlMPSP, constraints);
this.add(pnlMPSP);
GridBagLayout gridbagMPSP = new GridBagLayout();
GridBagConstraints constraintsMPSP = new GridBagConstraints();
pnlMPSP.setLayout(gridbagMPSP);
constraintsMPSP.fill = GridBagConstraints.BOTH;
constraintsMPSP.insets = new Insets(10, 10, 10, 10);
constraintsMPSP.weightx = 1.0;
lblMPSP = new JLabel();
lblMPSP.setText("asdf");
lblMPSP.setForeground(Color.WHITE);
lblMPSP.setFont(new Font("Arial", Font.PLAIN, 20));
gridbagMPSP.setConstraints(lblMPSP, constraintsMPSP);
pnlMPSP.add(lblMPSP);
lblMPSPTitle = new JLabel();
lblMPSPTitle.setText("MP");
lblMPSPTitle.setForeground(Color.WHITE);
lblMPSPTitle.setFont(new Font("Arial", Font.PLAIN, 60));
lblMPSPTitle.setHorizontalAlignment(SwingConstants.RIGHT);
constraintsMPSP.gridwidth = GridBagConstraints.REMAINDER;
gridbagMPSP.setConstraints(lblMPSPTitle, constraintsMPSP);
pnlMPSP.add(lblMPSPTitle);
pgbMPSP = new JProgressBar();
pgbMPSP.setBackground(new Color (0, 0, 255));
pgbMPSP.setValue(25);
constraintsMPSP.weightx = 0.0;
gridbagMPSP.setConstraints(pgbMPSP, constraintsMPSP);
pnlMPSP.add(pgbMPSP);
//Middle Left
lblNotifications = new JLabel();
lblNotifications.setText("<html>N<br>o<br>t<br>i<br>f<br>i<br>c<br>a<br>t<br>i<br>o<br>n<br>s</html>");
lblNotifications.setFont(new Font("Arial", Font.PLAIN, 20));
lblNotifications.setBackground(Color.WHITE);
gridbag.setConstraints(lblNotifications, constraints);
this.add(lblNotifications);
//Middle Center
txtNotifCenter = new JTextPane();
txtNotifCenter.setBackground(new Color (205, 160, 96));
txtNotifCenter.setEnabled(false);
txtNotifCenter.setDisabledTextColor(Color.black);
scpNotifCenter = new JScrollPane(txtNotifCenter);
scpNotifCenter.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED);
gridbag.setConstraints(scpNotifCenter, constraints);
this.add(scpNotifCenter);
//Middle Right
txtXPInfo = new JTextPane();
txtXPInfo.setBackground(new Color (205, 160, 96));
txtXPInfo.setEnabled(false);
txtXPInfo.setDisabledTextColor(Color.black);
scpXPInfo = new JScrollPane(txtXPInfo);
scpXPInfo.setVerticalScrollBarPolicy(ScrollPaneConstants.VERTICAL_SCROLLBAR_AS_NEEDED);
constraints.gridwidth = GridBagConstraints.REMAINDER;
gridbag.setConstraints(scpXPInfo, constraints);
this.add(scpXPInfo);
//I haven't made the bottom part yet
this.pack();
If this was run, the lblNotifications and txtNotifCenter (or scpNotifCenter) seemed to have the same width. I wanted to make it like in the picture. Am I supposed to use another layout, or am I just using the gridbag layout in the wrong way? Thank you in advance!
GridBagLayout is very difficult to use and only people that are a glutton for punishment try to use it. It was actually originally intended to be used by GUI builders rather than be coded by hand.
You should use nested layouts. You actually have a pretty standard layout. For your main window use BorderLayout (and this is the default layout of all top-level containers like JFrame).
Your HP, Start Adventure, and MP will be in a JPanel that uses a X_AXIS BoxLayout (JPanels use FlowLayout by default, so you will have to set it to BoxLayout). That JPanel will go in the NORTH position of the BorderLayout.
Your two notification text areas would probably go best in a JSplitPane (with one text area on the left side, the other text area on the right side), then put the split pane in the CENTER of the BorderLayout.
Then your CharMode, Level, and Logout will be in yet another JPanel using X_AXIS BoxLayout. That JPanel will go in the SOUTH position of your BorderLayout.
Tutorials for Border and Box Layouts:
https://docs.oracle.com/javase/tutorial/uiswing/layout/border.html
https://docs.oracle.com/javase/tutorial/uiswing/layout/box.html
Split Panes:
https://docs.oracle.com/javase/tutorial/uiswing/components/splitpane.html
It is unsure which parts of your screen are components and which are not (for example is the hp display one component or a group of them?) but GridBagLayout can certainly do what you want.
The key is not to try and do it all with one GridBagLayout, since then everything needs to line up in a grid.
Instead split your screen into three rows. Use on layout to arrange the three rows (for example BoxLayout) and then use a separate layout manager inside each row (for example GridBagLayout) to lay out the components within that row.
I have some JLabel components in a JPanel (taskPanel) with a BoxLayout (which is in a panel with a GridBagLayout) and the labels are refusing to be aligned to the right. They keep aligning to the left no matter how I manipulate them.
Here I setup the GridBagConstraints for the panel that has the labels
GridBagConstraints taskPanelC = new GridBagConstraints();
taskPanelC.gridx = 4;
taskPanelC.gridy = 0;
taskPanelC.gridwidth = 1;
taskPanelC.anchor = GridBagConstraints.NORTHEAST;
taskPanelC.weighty = 1;
taskPanelC.weightx = 1;
taskPanelC.insets = new Insets(10, 10, 10, 10);
timePanel.add(taskPanel, taskPanelC);
Here are the GridBagConstraints for the panel before the task panel
//Setup the gridBagLayout
GridBagConstraints timeTextC = new GridBagConstraints();
timeTextC.gridx = 1;
timeTextC.gridy = 0;
timeTextC.gridwidth = 3;
timeTextC.anchor = GridBagConstraints.CENTER;
timeTextC.weighty = 1;
timeTextC.weightx = 1;
Here I add a header to the taskPanel (I don't really care how this is aligned)
taskListLabel = new JLabel("Task List");
taskListLabel.setFont(new Font("Helvetica", Font.BOLD, 24));
taskPanel.add(taskListLabel);
Here is where I am adding the labels I want to be right-justified/aligned. I have tried setHorizontalTextPosition and setAlignmentX and both do not work, causing the text to stay left aligned. However, when I tried setAlignmentX, the header became unaligned with the task labels
JLabel task = new JLabel(name, SwingConstants.RIGHT);
//Allow deleting of the label
task.addMouseListener(new ClickListener());
//Add task to the task panel
taskPanel.add(task);
This is what it currently looks like
I want the text under task list to be right-aligned so the time is always on the right
Here is a link to the full code in case the summary was not enough: Github Repo
Check out the following methods from the JLabel API:
setHorizontalAlignment(...) - used to align the text when the width of the label is greater than the width of the text
setAlignmentX(...) - might be used by the layout manager to align component
I copied the entire code from the link
https://github.com/kennyftang/WorkflowTimer/blob/master/src/WorkflowTimer.java
I guess the code is incomplete, as addTask(String name) method is not called anywhere in the code.
I am really confused about which label you want to be on the right side? As I observed that the "task list" are already on the right side.
Please provide the image explaining which label you want on which side? Also, don't use so many layouts and get confused for this small UI just one layout is enough.
Step 1 Comment the following line.
// taskPanel.add(taskListLabel);
Step2 Add the following 4 lines in that place,
JPanel panel = new JPanel();
panel.setLayout(new BorderLayout());
panel.add(taskListLabel, BorderLayout.EAST);
taskPanel.add(panel,BorderLayout.LINE_END);
Step3 Comment the following line.
//taskPanel.add(task);
Step4 Add the following 4 lines in that place,
JPanel panel = new JPanel();
panel.setLayout(new BorderLayout());
panel.add(task,BorderLayout.EAST);
taskPanel.add(panel,BorderLayout.LINE_END);
Let me know if you have any issues. Thanks.
I know this is bit heavy solution, here instead of Jpanel we may use some even light weight component as well.
Im making an application that uses a lot of constructors, and I understood that you cant use the Drag and Drop tool of netbeans for making a constructor, and i thought it was good idea to learn how to code fully organized windows, anyways I read a DEITEL Java book that uses a method for adding objects to the container, here it is:
private void addobject(Component componente, int column, int row, int width
int height){
//C will be the GridBagConstraints
//And I made a new GridBagLayout called "v"
//My Panel or container is called objcontainer and the LayoutManager is v
c.gridx = column;
c.gridy = row;
c.gridwidth = width;
c.gridheight = height;
v.setConstraints(componente, c);
objcontainer.add(componente);
}
The method is declared in the same class in where the constructor is, it worked separating only by one gridy. But when I put it 2 or more away that the last object it just stays like if I put 1.
I dont know if thats how it works, also the anchors dont work perfectly, besides the LINE START one, the Center ones are failing.
Here is the code, anyways thanks:
package Windows;
import java.awt.*;
import javax.swing.*;
public class agregaringreso extends JDialog{
private int ingreso;
private String nombreingreso;
private String Frecuencia [] = {"Solo una vez", "Cada semana","Cada 2 semanas", "Cada 3 semanas", "Cada mes,"};
Container contenedor;
JPanel objcontainer;
GridBagLayout esquema;
GridBagConstraints c;
JButton aceptar;
JLabel title;
JLabel ingreso2;
JLabel nombreingreso2;
JLabel frecuencia2;
JTextField ingreso3;
JTextField nombreingreso3;
JComboBox frecuencia3;
private void addobjeto(Component componente, int columna, int fila, int ancho, int alto){
c.gridx = columna;
c.gridy = fila;
c.gridwidth = ancho;
c.gridheight = alto;
esquema.setConstraints(componente, c);
objcontainer.add(componente);
}
public agregaringreso(){
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
setTitle("Agregar Nuevo Ingreso - EkPek");
pack();
setResizable(false);
setSize(500, 200);
setLocationRelativeTo(null);
//FASE DE INICIALIZACION
contenedor = getContentPane();
objcontainer = new JPanel();

c = new GridBagConstraints();

title = new JLabel("Agregar Nuevo Ingreso");
ingreso2 = new JLabel("Monto del Ingreso: ");
nombreingreso2 = new JLabel("Nombre del Ingreso: ");
frecuencia2 = new JLabel("Frecuencia con la cual recibe el ingreso: ");
ingreso3 = new JTextField("Escriba aqui el monto");
nombreingreso3 = new JTextField("Escriba aqui el nombre");
frecuencia3 = new JComboBox(Frecuencia);
//FASE DE ACOMODO
c.anchor = GridBagConstraints.CENTER;
addobjeto(title, 0, 0, 1, 1);
c.anchor = GridBagConstraints.LINE_START;
addobjeto(nombreingreso2 , 0, 4, 1, 1);
addobjeto(nombreingreso3, 1, 4, 1, 1);
addobjeto(ingreso2, 0, 5, 1, 1);
addobjeto(ingreso3, 1, 5, 1, 1 );
addobjeto(frecuencia2, 0 , 6, 1, 1);
addobjeto(frecuencia3, 1, 6, 1, 1);
c.anchor = GridBagConstraints.CENTER;
addobjeto(aceptar,0 ,7 ,1, 1);
contenedor.add(objcontainer);
objcontainer.setLayout(esquema);
setVisible(true);
}
}
The order in which you do things is very important. It pointless doing something like...
objcontainer = new JPanel();
esquema = new GridBagLayout();
// Add a bunch of stuff
objcontainer.setLayout(esquema);
You've basically added components to a container (which is using a FlowLayout) and then changed the layout manager. The constraints won't carry across, they are typically incompatiable between layouts (what's a FlowLayout going to do with GridBagConstraints anyway)
Instead, set the layout first
objcontainer = new JPanel();
esquema = new GridBagLayout();
objcontainer.setLayout(esquema);
// Add components.
This also holds true for when you establish a window...
public agregaringreso(){
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
setTitle("Agregar Nuevo Ingreso - EkPek");
pack();
setResizable(false);
setSize(500, 200);
setLocationRelativeTo(null);
It's all kind of pointless, as you've not actually added anything to the window, so pack can't actually do it's job (it's got nothing to pack)
Instead, build the UI first, the "set up" the window properties...
public agregaringreso(){
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
setTitle("Agregar Nuevo Ingreso - EkPek");
//FASE DE INICIALIZACION
contenedor = getContentPane();
contenedor.setBackground(Color.RED);
objcontainer = new JPanel();
esquema = new GridBagLayout();
objcontainer.setLayout(esquema);
c = new GridBagConstraints();
// Add components
setResizable(false);
pack();
setLocationRelativeTo(null);
setVisible(true);
}
it worked separating only by one gridy. But when I put it 2 or more away that the last object it just stays like if I put 1.
If you mean that jumping the value of gridy doesn't do anything than you're right, it's intended. The grid only consists of rows and columns which have components in them.
Example: if you have 2 components, the first at (0,0) and the second at (0,4), then the gridy values 1 through 3 are not counted. The result is that the second component is actually at (0,1). Same goes for gridx.
also the anchors dont work perfectly, besides the LINE START one, the Center ones are failing.
In your example the CENTER anchor value is functioning as intended. If the component is smaller than its available space (and it was not instructed to fill that space with fill), it will be aligned to the center of the space.
What you probably want it for the component to be in the center of the whole grid, and not in the center of its available space. To do this, you must set it so that the component spans the grid's width (or height) by setting its gridwidth appropriately.
Picture comparison
#MadProgrammer's answer already explained how to fix your setup (I will mention it below in the notes). You're supposed to get the top picture after those corrections. The red lines separate rows and the blue lines separate columns - this is your grid.
You see that the components in the first and last rows are centered in column 0 because this is their available space. In the bottom picture, they are centered in both columns since I instructed them to span 2 columns.
I also noted a space discrepancy in the top picture with a yellow rectangle. This happens because the components are not filling all their available space. While it's your choice, it is customary in such layout to do as shown in the bottom picture.
Code comparison
c.anchor = GridBagConstraints.CENTER; // Redundant - default
addobjeto(title, 0, 0, 2, 1);
c.anchor = GridBagConstraints.LINE_START;
c.fill = GridBagConstraints.HORIZONTAL;
addobjeto(nombreingreso2, 0, 1, 1, 1);
addobjeto(nombreingreso3, 1, 1, 1, 1);
addobjeto(ingreso2, 0, 2, 1, 1);
addobjeto(ingreso3, 1, 2, 1, 1);
addobjeto(frecuencia2, 0, 3, 1, 1);
addobjeto(frecuencia3, 1, 3, 1, 1);
c.anchor = GridBagConstraints.CENTER;
c.fill = GridBagConstraints.NONE;
addobjeto(aceptar, 0, 4, 2, 1);
Set the gridwidth of title and aceptar to 2 (GridBagConstraints.REMAINDER will also work) to allow them to span 2 columns.
For the rest of the components, set c.fill = GridBagConstraints.HORIZONTAL; to allow them to align nicely with themselves (yellow rectangle). Remember to reset it c.fill = GridBagConstraints.NONE; for aceptar if you don't want the button to strech.
Specifying c.anchor = GridBagConstraints.CENTER; is redundant for the first component as it is the default, but it can make the code clearer.
Notes:
You don't need your JLabels to be fields as you probably don't need to hold a reference to them. Local variables will do just as well and will decrease the memory usage.
Class names should start with an uppercase (Agregaringreso).
As for my "setup" (as MadProgrammer explained): before adding the components I have
esquema = new GridBagLayout();
objcontainer = new JPanel(esquema);
c = new GridBagConstraints();
and at the end I have
getContentPane().add(objcontainer);
setDefaultCloseOperation(DISPOSE_ON_CLOSE);
setTitle("Agregar Nuevo Ingreso - EkPek");
pack();
setResizable(false);
setLocationRelativeTo(null);
setVisible(true);
(You don't need to hold a reference to the content pane.)
I want to set the size of my JButtons that are at the center of my screen to become larger but I can't seem to find how to do that using GridBagLayouts.
Here is how it looks like :
Here is my code :
// Client
c.fill = GridBagConstraints.BOTH;
c.anchor = GridBagConstraints.CENTER;
c.gridy = 5;
c.gridx = 5;
c.gridwidth = 1;
c.gridheight = 1;
c.insets = new Insets(10, 1, 1, 10);
p.add(b[0], c);
// Server
c.fill = GridBagConstraints.BOTH;
c.anchor = GridBagConstraints.CENTER;
c.gridy = 10;
c.gridx = 5;
c.gridwidth = 1;
c.gridheight = 1;
c.insets = new Insets(10, 1, 1, 10);
p.add(b[1], c);
I want the buttons to take up a larger portion of the empty space around them.
More information was added: Buttons have 50% of the width and [about] 20% of the height of parent [together 50% height including the space in between]. (Slightly rewritten to match the suggestion.)
Solution
Combination of simple Layouts Layouts. Although if you do it like this you will have 3 columns or 3 rows which can't be joined, the rest can easily be changed later:
// row variation
JPanel parent = new JPanel();
parent.setLayout(new GridLayout(3, 1));
parent.add(new JPanel()); // placeholder for 1st row
JPanel row = new JPanel(); // 2nd row
row.setLayout(new GridLayout(1, 3)); // create 3 cells of equal size
row.add(new JPanel()); // 2nd row, 1st cell placeholder
// now you have a 33% x 33% (oops) rectangle in the middle
JPanel controls = new JPanel();
controls.setLayout(new GridLayout(2, 1, 10, 10));
controls.setBorder(BorderFactory.createEmptyBorder(10, 10, 10, 10);
controls.add(new JButton("Client"));
controls.add(new JButton("Server"));
row.add(controls); // add 2nd row, 2nd cell
row.add(new JPanel()); // 2nd row, 3rd cell placeholder
parent.add(row); // add 2nd row
parent.add(new JPanel()); // placeholder for 3rd row
Easy, but you won't be able to join the cells later:
JPanel parent = new JPanel();
parent.setLayout(newGridLayout(9, 9));
Bottom line: combine different layout managers, put your 2 buttons inside a panel and put some placeholders inside, then it should also work fine with GridBagLayout. That said, I would try to stay flexible by writing reusable components which can easily be combined with any layout manager. Then you don't have to use placeholders superfluous code in order to display the components correctly.
Old Answer
Alternative Solution: Use BoxLayout
BoxLayout is more intuitive and easier to understand when looking at code (of course this is only an opinion).
Decide how your window is structered (is it more like big horizontal components on top of each other PAGE_AXIS or big vertical components next to each other LINE_AXIS) and use this as the outer BoxLayout:
JPanel content = new JPanel(); // or frame
content.setLayout(new BoxLayout(content, BoxLayout.LINE_AXIS));
Add the components along the axis, where you have more than one component along the other axis use a 2nd BoxLayout. You can space components by creating rigid areas (empty rectangles always having the same size) or by adding glue (expanding like gum together with the components).
content.add(BoxLayout.createHorizntalGlue());
JPanel col = new JPanel();
col.setLayout(new BoxLayout(col, BoxLayout.PAGE_AXIS));
JButton clientBtn = new JButton("Client");
JButton serverBtn = new JButton("Server");
col.add(BoxLayout.createVerticalGlue());
col.add(clientBtn);
col.add(BoxLayout.createRigidArea(new Dimension(1, 10)));
col.add(serverBtn);
col.add(BoxLayout.createVerticalGlue());
content.add(col);
content.add(BoxLayout.createHorizontalGlue());
I can't imagine what do you want, but if you want your button to fill around, you can add
c.weightx = ...; //Specifies how to distribute extra horizontal space.
or c.weighty = ...; //Specifies how to distribute extra vertical space.
button.setMargin( new Insets(50, 50, 50, 50) );
This will add extra space to the button and allow the layout managers to do their job based on the preferred size of the button.
I want to resize my buttons to be the same size and place then in a Panel on a JApplet. I have tried using
public void init() {
// TODO start asynchronous download of heavy resources
JButton btnWestern=new JButton("Western");
JButton btnPop=new JButton("Pop");
GridBagConstraints c4=new GridBagConstraints();
JPanel jPanel1 = new JPanel();
getContentPane().setLayout(new java.awt.GridBagLayout());
jPanel1.setLayout(new java.awt.GridBagLayout());
c4.gridx = 0;
c4.gridy = 0;
c4.insets = new Insets(36, 10, 0, 249);
jPanel1.add(btnWestern, c4);
c4.gridx = 0;
c4.gridy = 1;
c4.insets = new Insets(33, 10, 0, 249);
jPanel1.add(btnPop, c4);
add(jPanel1, new java.awt.GridBagConstraints());
}
When I run, this is what I get
But I noticed that if I change the button text to be the same or have the same length, like
JButton btnWestern=new JButton("Button1");
JButton btnPop=new JButton("Button2");
I get the desired output
What can I do to make sure that even the text of the buttons are not the same length, the buttons are the same size?
I'd suggest reading through the How to Use GridBagLayout tutorial if you haven't already. GridBagLayout is powerful but it is also one of the more complex LayoutManagers available.
I believe you need to set the GridBagConstraints.fill property to get the behavior you desire.
In your case this should be something like
c4.fill = GridBagConstraints.HORIZONTAL;
Edit (A bit of explanation for the observed behavior) When you use the same text on both buttons, their calculated size ends up being the same, so they are rendered as you want. When you use different size text, the buttons will render in a size that fits the text by default. The default value for GridBagConstraints.fill is GridBagConstraints.NONE which indicates to the LayoutManger to not resize the component. Changing the fill to GridBagConstraints.HORIZONTAL tells the LayoutManger to resize the component horizontally to fill the display area.
