I hava a problem with the applet when it is converted into an executable. the applet has three buttons with text as shown in pic_1 below, and when it is converted into an executable, the text of the three buttons disappears and the buttons becomes smalle as shown in pic_2 below.
I downloaded some applications that generates the executable file from a .jar files, and the result after using these applications is the same, the applet runs but with no buttons.
please provide any suggestions to solve this issue.

this is my code, and I have no idea to make the text field next to the numbers. i try several times but does not comes together. whenever i add something the panels moves
its work only with the result but for the number doesn't work
here i used Box Layout for buttons and number 1 and number 2:
You were very close to solving it.
Replace this line
JPanel panel2 = new JPanel();
With this line
JPanel panel2 = new JPanel(new GridLayout(2, 2));
Then, get rid of these 3 lines
BoxLayout layout2 = new BoxLayout(panel2, BoxLayout.Y_AXIS);
panel2.setLayout(layout2);
frame.setLayout(new FlowLayout());
Now your code looks like this
I have the following Java GUI for my project. For some reason, the middle and right panels have been put below leaving empty spaces - marked in red. Is there a way to pull the panels up to fill the spaces.
These empty spaces does not look good. I have tried to check all code but cannot pinpoint where to correct.
Thanks in advance.

I have solved the problem by using Borderlayout and assigning the main panel to it.
The assigning the WEST, CENTER and EAST regions to it.
I have added the code below in the code above at places where the main panel is being added to.
Thank you for the advice to start debugging by using MRE approach.
BorderLayout layout = new BorderLayout();
main.setLayout(layout);
main.add(left,BorderLayout.WEST);
main.add(middle,BorderLayout.CENTER);
main.add(right,BorderLayout.EAST);
I'm trying to fit three JPanel (dataPanel, tablePanel and btnPanel), so this is how far I got:
The thing is that the middle panel (tablePanel) is cropped on the top and the header is not visible. Also I added a JScrollPane to it that doesn't appear either. I'm new to Java Swing, so here's my code:
JFrame frame = new JFrame("Crear pedido");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.setSize(500,500);
//frame.setSize(300, 150);
// or frame.pack() to "pack" all the components in this frame
frame.setVisible(true); // show it
frame.setResizable(false);
frame.setLocationRelativeTo(null);
JPanel dataPanel = new JPanel();
dataPanel.setLayout(new BoxLayout(dataPanel, BoxLayout.X_AXIS));
//frame.add((Component) BorderFactory.createEmptyBorder(30,0,0,0));
dataPanel.setBorder(new EmptyBorder(20,0,30,0));
frame.add(dataPanel, BorderLayout.NORTH);
JLabel id = new JLabel("ID:");
JLabel date = new JLabel("Fecha:");
JLabel dept = new JLabel("Departamento");
JTextField idInput = new JTextField (5);
idInput.setMaximumSize(new Dimension(70,25));
JFormattedTextField dateInput = new JFormattedTextField(df);
dateInput.setMaximumSize(new Dimension(70,25));
JComboBox deptSelect = new JComboBox(selectArray);
deptSelect.setMaximumSize(new Dimension(70,25));
id.setAlignmentX(Component.CENTER_ALIGNMENT);
date.setAlignmentX(Component.CENTER_ALIGNMENT);
dept.setAlignmentX(Component.CENTER_ALIGNMENT);
idInput.setAlignmentX(Component.CENTER_ALIGNMENT);
dateInput.setAlignmentX(Component.CENTER_ALIGNMENT);
deptSelect.setAlignmentX(Component.CENTER_ALIGNMENT);
dataPanel.add(Box.createRigidArea(new Dimension(30,0)));
dataPanel.add(id);
dataPanel.add(idInput);
dataPanel.add(Box.createRigidArea(new Dimension(30,0)));
dataPanel.add(date);
dataPanel.add(dateInput);
dataPanel.add(Box.createRigidArea(new Dimension(30,0)));
dataPanel.add(dept);
dataPanel.add(deptSelect);
JPanel productPanel = new JPanel();
productPanel.setLayout(new BoxLayout(productPanel, BoxLayout.Y_AXIS));
frame.add(productPanel, BorderLayout.CENTER);
JTable table = new JTable(data, headerProductos);
table.setMaximumSize(new Dimension(500,250));
table.setAlignmentX(Component.CENTER_ALIGNMENT);
table.setAlignmentY(Component.CENTER_ALIGNMENT);
table.getTableHeader().setForeground(Color.blue);
table.setEnabled(false);
JScrollPane scroll = new JScrollPane(table);
productPanel.add(table);
table.add(scroll);
JPanel btnPanel = new JPanel();
btnPanel.setLayout(new BoxLayout(btnPanel, BoxLayout.X_AXIS));
btnPanel.setBorder(new EmptyBorder(150,0,0,0));
frame.add(btnPanel, BorderLayout.SOUTH);
Replace lines:
productPanel.add(table);
table.add(scroll);
with:
productPanel.add(scroll);
I have Panel that contains JLayeredPane which contains two JPanels and each of them two JLabels.
Panel panel2 = new Panel();
JLayeredPane westP = new JLayeredPane();
westP.setLayout(null);
westP.setPreferredSize(new Dimension(100,400));
westP.setBackground(Color.blue);
JPanel layerOne = new JPanel();
jl1 = new JLabel("player1: ");
layerOne.add(jl1);
layerOne.setBounds(5, 100, 50, 50);
jl1Add = new JLabel("");
layerOne.add(jl1Add);
westP.add(layerOne,0, 0);
similar for another JPanel except
westP.add(LayerTwo,0,1);
and later:
panel2.setLayout(new BorderLayout());
panel2.add(westP);
add(panel2, BorderLayout.WEST);
later when I simply test it, I get lbl1, lbl1Add, lbl2 shown on GUI but not lbl2Add?
if (activeColour==RED)
{
timesPlayedRed++;
jl1Add.setText("");
jl1Add.setText(String.valueOf((timesPlayedRed)));
activeColour=YELLOW;
}
else
{
timesPlayedYellow++;
jl2Add.setText("");
jl2Add.setText(String.valueOf((timesPlayedYellow)));
activeColour=RED;
}
I am just trying out java and netbeans.
I'm in the position where I have to reuse and modify another persons code to create an image processing application. The following code is used to setup the frame and its GUI. The problem I'm having is that when the file word is clicked on the menubar the menuitems are listed below the canvas contained in the originalImage container.
Here is the code:
public ImageLoader(){
super("IRIS Application");
JMenu fileMenu = new JMenu("File");
JMenuItem fileOpenChoice = new JMenuItem("Open File");
fileOpenChoice.addActionListener(new FileOpener());
fileMenu.add(fileOpenChoice);
JMenuItem fileSaveChoice = new JMenuItem("Save File");
fileSaveChoice.addActionListener(new FileSaver());
fileMenu.add(fileSaveChoice);
JMenu processMenu = new JMenu("Process");
JMenuItem reduceContrast = new JMenuItem("Reduce Contrast");
reduceContrast.addActionListener(new ReduceContrast());
processMenu.add(reduceContrast);
JMenuItem scale = new JMenuItem("Scale");
scale.addActionListener(new Scaler());
processMenu.add(scale);
JMenuItem sobel = new JMenuItem("Sobel");
sobel.addActionListener(new Sobel());
processMenu.add(sobel);
JMenuItem prewitt = new JMenuItem("Prewitt");
prewitt.addActionListener(new Prewitt());
processMenu.add(prewitt);
originalImage = new BufferedImage(565, 584, BufferedImage.TYPE_BYTE_GRAY);
processedImage = new BufferedImage(565, 584, BufferedImage.TYPE_BYTE_GRAY);
originalRaster = originalImage.getRaster();
processedRaster = processedImage.getRaster();
ic = new ImageCanvas();
pc = new ImageCanvas();
Container content = this.getContentPane();
content.setLayout(new FlowLayout());
JPanel originalContainer = new JPanel();
originalContainer.add(ic);
originalContainer.setSize(ic.getWidth(), ic.getHeight());
originalContainer.setBorder(new EtchedBorder());
JPanel processedContainer = new JPanel();
processedContainer.add(pc);
processedContainer.setSize(pc.getWidth(), pc.getHeight());
processedContainer.setBorder(new EtchedBorder());
JPanel imagePanel = new JPanel();
imagePanel.setLayout(new FlowLayout());
imagePanel.add(originalContainer);
imagePanel.add(processedContainer);
//content.add(imagePanel, BorderLayout.NORTH);
JPanel originalGrid = new JPanel();
originalGrid.setLayout(new GridLayout(0,1,5,0));
JPanel processedGrid = new JPanel();
processedGrid.setLayout(new GridLayout(0,1,5,0));
originalText = new JTextField("Original Text");
JButton originalButton = new JButton("View Coordinates Table");
originalGrid.add(originalText);
originalGrid.add(originalButton);
JTextField processedText = new JTextField("Processed Text");
JButton processedButton = new JButton("View Coordinates Table");
processedGrid.add(processedText);
processedGrid.add(processedButton);
JPanel informationPanel = new JPanel();
informationPanel.setBackground(Color.red);
informationPanel.setLayout(new BorderLayout());
informationPanel.add(originalGrid, BorderLayout.WEST);
informationPanel.add(processedGrid, BorderLayout.EAST);
//content.add(informationPanel, BorderLayout.SOUTH);
ic.addMouseMotionListener(new ImageMouseMotionListener(ic, originalText));
pc.addMouseMotionListener(new ImageMouseMotionListener(pc, processedText));
JMenuBar bar = new JMenuBar();
bar.add(fileMenu);
bar.add(processMenu);
content.add(imagePanel, BorderLayout.NORTH);
content.add(informationPanel, BorderLayout.SOUTH);
setJMenuBar(bar);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setSize(1200, 725);
setResizable(false);
setVisible(true);
setLocation(125, 0);
}
I know the menu bar is fine so I'm assuming its the way I've added the canvas to the JPanel. Should a set its z order in the JPanel?
I've read through the books I have at home and nothing mentions this kind of problem.
Thanks,
Daniel
Mixing AWT and Swing component will cause overlap issue, Canvas is a AWT component, use JPanel instead
After JDK1.6_12, you can use both safety.
