So I want to use the ocr-a font for my Text in my little Brick Breaker Game.
I tried to import a font I downloaded as .ttf. Then I tried to use it on my JButton with "btn_StartGame.setFont(ocr);". But then when I try to run it the Font didn't change. Can somebody please help me. I'm still learning to code so if I can do something better just tell me.
This should only be something like a starting window and a game window where the actual game runs which is not created yet.

This is for a class assignment. I am supposed to load a file and display it on my Swing application.
I followed the process from the notes but they were vague, I also used other stackoverflow posts, but I am not able to get this to work. When I load an image the program does not crash, but nothing displays.
-Do I have to repaint or refresh the file after the image is loaded? I tried that but it did not work. what am I doing wrong? The repaint method is commented.

}
As was mentioned, you need to call frame.revalidate(); after you add the new component.
You also should call image.setPreferredSize(new Dimension(500, 500)); or similar to ensure that your image isn't tiny.
I am getting files from JFileChooser and showing them by reading with BufferedImage and putting in JLabels but there is a problem that my images are not completely shown in JLabels. Here is my code
public class ImagePreview
{
JPanel PicHolder= new JPanel();
public ImagePreview()
{
JButton GetImages = new JButton("Browse Images");
GetImages.addMouseListener(new MouseAdapter()
{
public void mouseClicked(MouseEvent evt)
{
CreatePreviews();
};
});
PicHolder.add(GetImages);
JFrame MainFrame = new JFrame("Image Preview");
MainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
MainFrame.getContentPane().add(PicHolder);
MainFrame.pack();
MainFrame.setVisible(true);
}
public void CreatePreviews()
{
JFileChooser chooser = new JFileChooser();
chooser.setMultiSelectionEnabled(true);
File[] selectedCarImages = chooser.getSelectedFiles();
for(int a=0; a<selectedImages.length; a++)
{
try
{
BufferedImage myPicture = ImageIO.read(new File(selectedImages[a].getAbsolutePath()));
JLabel picLabel = new JLabel(new ImageIcon(myPicture));
PicHolder.add(picLabel);
}
}
}
public static void main(String[] args)
{
java.awt.EventQueue.invokeLater(() -> {
new ImagePreview();
});
}
}
When I run this code, it shows user selected images but they are kind of automatically croped and not showing completely in JLabels.
What's wrong here? Why JLabels do not show full images?
You're adding all the components and images to a single panel having the default FlowLayout. Instead, use GridLayout for the picture labels and add the browse button to the frame's default BorderLayout, as shown below.
As tested:

In the last question I was asking the community why my JPopupMenu did not appear on the screen.
I was unable to come up with a simple , runnable, compilable example.
So, here is what I did for you guys:
Is the area too small to draw a popup?
I want my popup to be like this:
The code of what I did is visible in the first photo.
Code:
/* The old code entered here has been removed */
Complete code can be found here
edit 2
I copied the various JRadioButtonMenuItem and the setupJPopup() into a new file and ran. It works. Why doesn't it work in ScreenRecorder class?
Code
package demo;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import javax.swing.ButtonGroup;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JMenu;

public class PopupTrial {
public PopupTrial(){
setupJPopup();
JFrame frame = new JFrame();
try{
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
}catch(Exception e){
}
frame.getContentPane().add(label);
label.addMouseListener(new MouseAdapter(){
#Override
public void mouseClicked(MouseEvent e){
popup.show(e.getComponent(), e.getX(), e.getY());
}
});
frame.setVisible(true);
frame.setSize(300, 300);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable(){
#Override
public void run(){
new PopupTrial();
}
});
}
public void setupJPopup(){
encodingGroup.add(avi);
encodingGroup.add(quicktime);

}
JLabel label = new JLabel("Click Me");
ButtonGroup recordingAreaGroup = new ButtonGroup();
ButtonGroup cursorGroup = new ButtonGroup();
ButtonGroup encodingGroup = new ButtonGroup();
JPopupMenu popup = new JPopupMenu();
JRadioButtonMenuItem avi = new JRadioButtonMenuItem("AVI",true);
JRadioButtonMenuItem quicktime = new JRadioButtonMenuItem("QuickTime",false);
JRadioButtonMenuItem entireScreen = new JRadioButtonMenuItem("Entire Screen",true);
JRadioButtonMenuItem custom = new JRadioButtonMenuItem("Custom...",false);
JMenuItem selectCursor = new JMenu("Select a cursor");
JRadioButtonMenuItem selectWhiteCursor = new JRadioButtonMenuItem("White Cursor",true);
JRadioButtonMenuItem selectBlackCursor = new JRadioButtonMenuItem("Black Cursor",false);
JRadioButtonMenuItem selectNoCursor = new JRadioButtonMenuItem("No Cursor",false);
}
No, the size of the JFrame isn't related to why the PopupMenu isn't showing. Here's an example showing something similar to what you want (and using similar methods) working:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class PopupMenu extends Box{
Dimension preferredSize = new Dimension(400,30);
public PopupMenu(){
super(BoxLayout.Y_AXIS);
final JPopupMenu menu = new JPopupMenu("Options");
for(int i = 1; i < 20; i++)
menu.add(new JMenuItem("Option" + i));
JLabel clickMe = new JLabel("ClickMe");
clickMe.setAlignmentX(RIGHT_ALIGNMENT);
clickMe.addMouseListener(new MouseAdapter(){
#Override
public void mouseClicked(MouseEvent e) {
menu.show(e.getComponent(), e.getX(), e.getY());
}});
add(clickMe);
}
public Dimension getPreferredSize(){
return preferredSize;
}
public static void main(String[] args) {
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setContentPane(new PopupMenu());
frame.validate();
frame.pack();
frame.setVisible(true);
}
}
Designing a questionary, the scope of answer can be elected by radioButtons.
To display a greater clickable area (the application is for touchscreen), I layed icon_1 over the radiobuttons.
Every mouseclick can change the displayed icon to icon_2 and permantly vice versa.
I am sorry, using
jRadioButtonActionPerformed
ImageIcon o_ButtonIcon = new ImageIcon ("....")
jRadioButton.setIcon(Icon m_ButtonIcon).
I get no changing, clickable image.
Can you please give me a helping hand?
Seems to be working fine.
Post an SSCCE to show specific problems.
Here is example ( i do not recommend getScaledInstance(..) just used it for quick example)

I have a problem with my JLayeredPane, I am probably doing something incredibly simple but I cannot wrap my head around it. The problem i have is that all the components are merged together and have not order. Could you please rectify this as I have no idea. The order I am trying to do is have a layout like this
output
label1 (behind)
input (in Front)
import java.awt.BorderLayout;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;
import java.io.IOException;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JTextArea;
import javax.swing.JTextField;
public class window extends JFrame implements KeyListener {
/**
*
*/
private static final long serialVersionUID = 7092006413113558324L;
private static int NewSize;
public static String MainInput;
public static JLabel label1 = new JLabel();
public static JTextField input = new JTextField(10);
public static JTextArea output = new JTextArea(main.Winx, NewSize);
public window() {
super("Satine. /InDev-01/");
JLabel label1;
NewSize = main.Winy - 20;
setLayout(new BorderLayout());
output.setToolTipText("");
add(input, BorderLayout.PAGE_END);
add(output, BorderLayout.CENTER);
input.addKeyListener(this);
input.requestFocus();
ImageIcon icon = new ImageIcon("C:\\Users\\" + System.getProperty("user.name") + "\\AppData\\Roaming\\.Satine\\img\\textbox.png", "This is the desc");
label1 = new JLabel(icon);
add(label1, BorderLayout.PAGE_END);
}
public void keyPressed(KeyEvent e) {
int key = e.getKeyCode();
if (key == KeyEvent.VK_ENTER) {
try {
MainMenu.start();
} catch (IOException e1) {
System.out.print(e1.getCause());
}
}
}
#Override
public void keyReleased(KeyEvent e) {
}
#Override
public void keyTyped(KeyEvent e) {
}
}
And the main class.
import java.awt.Container;
import java.io.IOException;
import javax.swing.JFrame;
import javax.swing.JLayeredPane;
public class main {
public static int Winx, Winy;
private static JLayeredPane lpane = new JLayeredPane();
public static void main(String[] args) throws IOException{
Winx = window.WIDTH;
Winy = window.HEIGHT;
window Mth= new window();
Mth.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Mth.setSize(1280,720);
Mth.setVisible(true);
lpane.add(window.label1);
lpane.add(window.input);
lpane.add(window.output);
lpane.setLayer(window.label1, 2, -1);
lpane.setLayer(window.input, 1, 0);
lpane.setLayer(window.output, 3, 0);
Mth.pack();
}
}
Thank you for your time and I don't expect the code to be written for me, all I want is tips on where I am going wrong.
I recommend that you not use JLayeredPane as the overall layout of your GUI. Use BoxLayout or BorderLayout, and then use the JLayeredPane only where you need layering. Also, when adding components to the JLayeredPane, use the add method that takes a Component and an Integer. Don't call add(...) and then setLayer(...).
Edit: it's ok to use setLayer(...) as you're doing. I've never used this before, but per the API, it's one way to set the layer.
