Using a Key to stop a timer outside of the jframe

So I'm making a simple AutoClicker just to test myself. Now I've ran into a small problem. I am trying to make it so when I use "control + minus" it stops the auto clicker. Problem is I have to have the jframe focused to do so. Is there any way I get the key the user touched outside of the jframe?
For example: Your playing cookie clicker and you hit "control and =" to start the auto clicker, then you can stop it while playing cookie clicker by doing "control and +"
My Listener:
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
public class JListener implements ActionListener
{
#Override
public void actionPerformed(ActionEvent e) {
if(e.getActionCommand() == "exit") {
GUIs.frame.dispose();
AutoClicker.getTimer().cancel();
} else if(e.getActionCommand() == "start") {
} else if(e.getActionCommand() == "stop") {
AutoClicker.getTimer().cancel();
}
}
}

why BufferedImage does not show full image in JLabel?

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:
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
public class ImagePreview {
JFrame mainFrame = new JFrame("Image Preview");
JPanel picHolder = new JPanel(new GridLayout(0, 1));
public ImagePreview() {
JButton getImages = new JButton("Browse Images");
getImages.addMouseListener(new MouseAdapter() {
#Override
public void mouseClicked(MouseEvent evt) {
CreatePreviews();
}
});
mainFrame.add(getImages, BorderLayout.NORTH);
mainFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
mainFrame.add(new JScrollPane(picHolder));
mainFrame.pack();
mainFrame.setLocationByPlatform(true);
mainFrame.setVisible(true);
}
public void CreatePreviews() {
JFileChooser chooser = new JFileChooser();
chooser.setMultiSelectionEnabled(true);
chooser.showOpenDialog(mainFrame);
File[] selectedImages = 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);
mainFrame.pack();
} catch (IOException ex) {
ex.printStackTrace();
}
}
}
public static void main(String[] args) {
java.awt.EventQueue.invokeLater(() -> {
new ImagePreview();
});
}
}

Adding Text In a New Window

I'm in a bit of a situation here.I'm making a new program, when you click on the menu bar it opens a new window for the Licence, now here is the problem, how would I add text into that new window, here is my code for the new window:
JFrame frame = new JFrame("Licence");
frame.setSize(500,120);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
I know this is a easy question, I just can't think of the correct code for it.

You can try something like
JDialog dialog = new JDialog(your_frame_reference, "Licence");
dialog .setModal(true);
dialog .setLocationRelativeTo(null);
dialog. getContentPane().add(new JLabel(your_text);
dialog .setVisible(true);

You can use label
JFrame frame = new JFrame("Licence");
JLabel label = new JLabel("Text-Only Label");
label.setFont(new Font("Serif", Font.PLAIN, 36));
frame.add(label);

You can add text by creating JLabels like so:
JLabel label = new JLabel("Hello World");
This can then be added to your JFrame.

Try this Example
import java.awt.BorderLayout;
import java.awt.Window;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JFrame;
import javax.swing.JLabel;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;
public class TestDialog {
protected static void initUI() {
JPanel pane = newPane("Label in frame");
JFrame frame = new JFrame("Title");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(pane);
frame.pack();
frame.setVisible(true);
}
public static JPanel newPane(String labelText) {
JPanel pane = new JPanel(new BorderLayout());
pane.add(newLabel(labelText));
pane.add(newButton("Open dialog"), BorderLayout.SOUTH);
return pane;
}
private static JButton newButton(String label) {
final JButton button = new JButton(label);
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
Window parentWindow = SwingUtilities.windowForComponent(button);
JDialog dialog = new JDialog(parentWindow);
dialog.setLocationRelativeTo(button);
dialog.setModal(true);
dialog.add(newPane("Label in dialog"));
dialog.pack();
dialog.setVisible(true);
}
});
return button;
}
private static JLabel newLabel(String label) {
JLabel l = new JLabel(label);
l.setFont(l.getFont().deriveFont(24.0f));
return l;
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
initUI();
}
});
}
}

stopCellEditing on JDialog

My question is similar to this one: JTable Cell Update doesn't work.
However, I am using JDialog instead of a JTable specified in above link. I have a custom class which extends JDialog. I use JEditorPane as a text-component in that dialog and create simple OK, Cancel buttons. Now the problem is, when I enter something in the JEdiorPane and presses OK button, the value is not applied to the text-component until I move the focus out of a JDialog or hit tab/ENTER.
I want the container to be notified that I am done with editing as soon as I press the OK button. In short I want to explicitly have a feature similar to stopCellEditing(). How can I do that?

See this example which seems to work correctly and does the same thing as you described:
import java.awt.BorderLayout;
import java.awt.GridLayout;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import javax.swing.JButton;
import javax.swing.JDialog;
import javax.swing.JEditorPane;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.SwingUtilities;
public class TestEditorPaneDialog {
public void init() {
final JFrame frame = new JFrame();
JButton clickMe = new JButton("Click me");
clickMe.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
showDialog(frame);
}
});
frame.add(clickMe);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setSize(400, 300);
frame.setLocationRelativeTo(null);
frame.setVisible(true);
showDialog(frame);
}
private void showDialog(final JFrame frame) {
final JDialog dialog = new JDialog(frame, true);
final JEditorPane pane = new JEditorPane();
pane.setText("Type something here");
JPanel south = new JPanel();
JPanel buttons = new JPanel(new GridLayout(1, 0, 10, 10));
JButton ok = new JButton("OK");
ok.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
dialog.dispose();
JOptionPane.showMessageDialog(frame, "You have typed in: " + pane.getText());
}
});
JButton cancel = new JButton("Cancel");
cancel.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
dialog.dispose();
}
});
buttons.add(ok);
buttons.add(cancel);
south.add(buttons);
dialog.add(new JScrollPane(pane));
dialog.add(south, BorderLayout.SOUTH);
dialog.setSize(250, 150);
dialog.setLocationRelativeTo(frame);
dialog.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
new TestEditorPaneDialog().init();
}
});
}
}

Java Swings Select Tab

I have 4 JPanels. In one of the panel I have a combo Box.Upon selecting "Value A" in combo box Panel2 should be displayed.Similarly if I select "Value B" Panel3 should be selected....
Though action Listener should be used in this context.How to make a call to another tab with in that action listener.
public class SearchComponent
{
....
.
public SearchAddComponent(....)
{
panel = addDropDown(panelList(), "panel", gridbag, h6Box);
panel.addComponentListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
ItemSelectable is = (ItemSelectable)actionEvent.getSource();
Object name=selectedString(is);
}
});
}
public static final Vector<String> panelList(){
List<String> panelList = new ArrayList<String>();
panelList.add("A");
panelList.add("B");
panelList.add("C");
panelList.add("D");
panelList.add("E");
panelList.add("F);
Vector<String> panelVector = null;
Collections.copy(panelVector, panelList);
return panelVector;
}
public Object selectedString(ItemSelectable is) {
Object selected[] = is.getSelectedObjects();
return ((selected.length == 0) ? "null" : (ComboItem)selected[0]);
}
}
