I am having a problem with loading images, as I am trying to load a background for my launcher. It works when I run it in Eclipse, but when I export it to a jar file, it doesn't. I have paged through the already asked questions, No luck.
Here is my code:
public void initializeJFrame(){
ImageIcon bg = new ImageIcon("src/background.png");
jb.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
if (jta.getText().length() < 3 || jta.getText().length() > 16) {
System.exit(-1);
} else {
try {
Runtime.getRuntime().exec(cmd, null, dir);
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
try {
Thread.sleep(500);
} catch (InterruptedException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
System.exit(0);
}
}
});
jf.setSize(WIDTH,HEIGHT);
jf.setTitle("Cracked Launcher");
jf.setLayout(null);
jf.setContentPane(new JLabel(bg));
jf.setResizable(false);
jf.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
t.start();
My image is in the src folder, nothing else. I cannot find what the problem is.
Thanks for your support.
ImageIcon bg = new ImageIcon("src/background.png");
This constructor takes a filename; it will not load resources from a jar. You want to pass a URL generated by a classloader, like so:
ImageIcon bg = new ImageIcon(getClass().retResource("background.png"));

I'm trying to implement a JEditorPane with hyperlinks. I'm using a HyperLinkListener but it seems to never trigger.
Code:
JEditorPane editorPane = new JEditorPane("text/html", programInfo);
editorPane.addHyperlinkListener(e -> {
System.out.println("CLICK");
if (e.getEventType().equals(HyperlinkEvent.EventType.ENTERED))
try {
if (Desktop.isDesktopSupported()) {
Desktop.getDesktop().browse(e.getURL().toURI());
}
} catch (IOException e1) {
e1.printStackTrace();
} catch (URISyntaxException e1) {
e1.printStackTrace();
}
});
JOptionPane.showMessageDialog(contentPane, editorPane);
Sample HTML:
<body>
<p><b>Author:</b> James - sample</p>
</body>
This leads to this:
But when I click on the links nothing happens.
Additional Info:
I'm testing this on Ubuntu 14.04.
I have set Look and Feel to system.
EDIT: thanks to #AndrewThompson for finding the real issue.
The reason why it does not trigger events is because the editor pane will only fire events when it is not editable. So, to make your code work you should add this line after the construction of the editorPane:
editorPane.setEditable(false);
Below you can find a self contained example:
public class TestFrame extends JFrame {
public static void main(String[] args) {
JEditorPane editorPane = new JEditorPane("text/html", "test link to example.com");
editorPane.addHyperlinkListener(new HyperlinkListener() {
#Override
public void hyperlinkUpdate(HyperlinkEvent e) {
System.out.println("CLICK");
if (e.getEventType().equals(HyperlinkEvent.EventType.ENTERED)) try {
if (Desktop.isDesktopSupported()) {
Desktop.getDesktop().browse(e.getURL().toURI());
}
}
catch (IOException e1) {
e1.printStackTrace();
}
catch (URISyntaxException e1) {
e1.printStackTrace();
}
}
});
editorPane.setEditable(false); // otherwise ignores hyperlink events!
JFrame frame = new JFrame("EditorPane Example");
frame.add(editorPane);
frame.setSize(300,200);
frame.setVisible(true);
} }
(sorry, I removed the lambda because I don't have a jdk8 on this PC)
The print button below displays the printer selection window but it prints nothing ...but the JTable contains data
print_button.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent e) {
try {
boolean complete = table2.print();
if (complete) {
JOptionPane.showMessageDialog(null, "Done printing");
} else {
JOptionPane.showMessageDialog(null, "printing.....");
}
} catch (PrinterException pe) {
}
}});
You need to give a size to your JTable in order to get printed:
table2.setSize(table2.getPreferredSize());
It's correct that it has data, but it needs to have a size for the priniting to work.
i got the answer
print_button.addActionListener(new ActionListener(){
#Override
public void actionPerformed(ActionEvent e) {
MessageFormat header = new MessageFormat("report printing");
MessageFormat footer = new MessageFormat("page{0,number,integer}");
try {
table1.print(JTable.PrintMode.NORMAL,header,footer);
} catch (PrinterException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}});
So I have this FormatedTextField
JFormattedTextField myFtf = new JFormattedTextField();
which has the following mask, placed in my application constructor
try {
myFtf.setFormatterFactory(
new DefaultFormatterFactory(
new MaskFormatter("###.###.###-##")));
} catch (java.text.ParseException ex) {
ex.printStackTrace();
}
Then, I have a two radio buttons, which should be changing the mask formatter in myFtf.
I have tried the following:
private radioButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try {
myFtf.setFormatterFactory(
new DefaultFormatterFactory(
new MaskFormatter("###.###.###-##")));
} catch (Exception e) {
e.printStackTrace();
}
}
private void radioButton2ActionPerformed(java.awt.event.ActionEvent evt) {
try {
myFtf.setFormatterFactory(
new DefaultFormatterFactory(
new MaskFormatter("##.###.###/####-##")));
} catch (Exception e) {
e.printStackTrace();
}
}
Which works fine, until I try to change their masks when there is input within the text field. In case there is, it doesn't change the mask anymore. Here are a couple of prints:
OK scenario:
img a:
switching radio buttons gives me this:
img b:
Buggy scenario:
img c:
switching radio buttons gives me this:
img d:
I was expecting img d to be exactly like img a
How can I dynamically change its mask correctly?
Change your action listeners to this:
private radioButton1ActionPerformed(java.awt.event.ActionEvent evt) {
try {
myFtf.setFormatterFactory(
new DefaultFormatterFactory(
new MaskFormatter("###.###.###-##")));
myFtf.setText("");
} catch (Exception e) {
e.printStackTrace();
}
}
private void radioButton2ActionPerformed(java.awt.event.ActionEvent evt) {
try {
myFtf.setFormatterFactory(
new DefaultFormatterFactory(
new MaskFormatter("##.###.###/####-##")));
myFtf.setText("");
} catch (Exception e) {
e.printStackTrace();
}
}
That should clear the text fields.
Good luck!
I got it working correctly! All I needed to do was adding a
myFtf.setValue(null);
after setting the new formatter factory. myFtf.setText("") wasn't working as expected, but it was a close shot! :-)
My image was displaying properly before I had a JButton on top of it. Now that I have added a JButton to my code, my image does not display. In the ActionPerformed method I am telling the button to setVisbible(false). When I click the button, it disapears and all that is behind it is the background.
public class Main extends JFrame implements ActionListener {
public static void main(String[] args) {
Main main = new Main();
}
ImageIcon GIF = new ImageIcon("src/Zombie Steve gif.gif");
JButton button = new JButton("Click me!");
JLabel Label = new JLabel(GIF);
public Main() {
button.addActionListener(this);
Label.setHorizontalAlignment(0);
JFrame Frame = new JFrame("zombieSteveGIF");
Frame.setSize(650, 650);
Frame.setVisible(true);
Frame.add(Label);
Frame.add(button);
Frame.setDefaultCloseOperation(EXIT_ON_CLOSE);
while (true) {
Frame.getContentPane().setBackground(Color.BLUE);
try {
Thread.sleep(200);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Frame.getContentPane().setBackground(Color.GREEN);
try {
Thread.sleep(200);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
Frame.getContentPane().setBackground(Color.RED);
try {
Thread.sleep(200);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public void actionPerformed(ActionEvent e) {
button.setVisible(false);
}
}
Your problem is that you have a BorderLayout (the default for JFrames), and you are adding two components in the same position. The default is BorderLayout.CENTER, and by adding two components with just the default constraints, the first one is removed and the second put in its place.
As for fixing your problem, what do you want to achieve? If you want the components to show on top of one another, you can use the OverlayLayout. If you don't want this, try some other layout manager.
I have a JDesktopPane with this code.
public class Menu extends JFrame implements ActionListener{
/**
* Creates new form Portada
*/
public static JDesktopPane desktop;
public JDesktopPane getDesktop() {
return desktop;
}
public Menu() {
desktop = new JDesktopPane();
setContentPane(desktop);
desktop.setDragMode(JDesktopPane.OUTLINE_DRAG_MODE);
initComponents();
}
}
then i add the new components like this
desktop.add(orden);
and when i want to call them i use
if(e.getSource()==jMenuItem1_1){
orden.setVisible(true);
desktop.setSelectedFrame(orden);
desktop.moveToFront(orden);
try {
orden.setSelected(true);
} catch (PropertyVetoException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
The problem i get is that when "orden" wants to pop out another JInternalFrame i use the next code.
searchSupplier.setVisible(true);
Main.getInstance().getPortada().getDesktop().add(searchSupplier);
Main.getInstance().getPortada().getDesktop()
.moveToFront(searchSupplier);
try {
searchSupplier.setSelected(true);
} catch (PropertyVetoException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
When I execute the event more than 2 times i get the next error:
Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: illegal component position
Where should i add the new JInternalFrame to the DesktopPane? or to Orden?, or What can i do to fix this error?
If the searchSupplier frame is already on the desktop, it is unlikely that you will able to add it again. Try using getParent to determine if the frame needs to be added
if (searchSupplier.getParent() == null) {
Main.getInstance().getPortada().getDesktop().add(searchSupplier);
}
searchSupplier.setVisible(true);
Main.getInstance().getPortada().getDesktop().moveToFront(searchSupplier);
try {
searchSupplier.setSelected(true);
} catch (PropertyVetoException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
