Anyone knows the tricks to use the MouseListener events so that I can hover a random text in the frame and highlight the hovered text. Then, use Clipboard to copy the hovered text.
My current codes:
Main Class:
package copypastefunctionality;
/**
*
* @author myu
*/
public class CopyPasteFunctionality {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
NewJFrame run = new NewJFrame();
run.runProgram();
}
}
Frame Class:
package copypastefunctionality;
import java.awt.Color;
import java.awt.datatransfer.*;
import java.awt.Toolkit;
/**
*
* @author myu
*/
public class NewJFrame extends javax.swing.JFrame {
/**
* Creates new form NewJFrame
*/
public NewJFrame() {
initComponents();
}
/**
* This method is called from within the constructor to initialize the form.
* WARNING: Do NOT modify this code. The content of this method is always
* regenerated by the Form Editor.

The GUI will look like this:
The result is not what I expecting. When I hover to the jLabel, it will change the text color and highlight the whole jLabel contents. While I only want to hover parts of the texts. And, currently I can only copy one jLabel, is there a way I can hover the whole frame's contents and copy them to the Clipboard?
