Class1 which is a NewJFrame Form and is also a calling class to class2, NewJFrame3 has a Jbutton component, jButton1, for which method actionPerformed has been over-ridden. I call the object with a thread. On calling, Class2, NewJFrame3, a new frame pops up. Problem is when I press the default cross of called class, NewJFrame3, button [X], both screens gets cancelled. I was not using threads before and was calling the layout method for JFrame3 with just object, but it had this problem, so i used thread but it wouldnt work.
Code of calling class (Layout is fine for this and on clicking its button JButton1, class NewJframe3’s layout pops up) :
public class NewJFrame extends javax.swing.JFrame implements ActionListener
{
public NewJFrame()
{
initComponents();
jButton1.addActionListener(this);
}
private void initComponents()
{
//layout code for JFrame1 – gives the desired layout/output
}
public void actionPerformed(ActionEvent e)
{
If(some_condition)
{
NewJFrame3 obj2 = new NewJFrame3();
Thread th1 = new Thread(obj2, "thread1");
th1.start();
}
}
public static void main(String args[])
{
java.awt.EventQueue.invokeLater(new Runnable()
{
public void run()
{
new NewJFrame().setVisible(true);
}
});
}//Main ends
}//Calling Class NewJFrame1 ends
Code for called class(same package) :
public class NewJFrame3 extends javax.swing.JFrame implements Runnable
{
public void run()
{
// System.out.println("Inside Run");
this.test();
this.setVisible(true);
}
protected void test()
{
//layout code for JFrame3 – gives the desired layout/output
}
PSVM()
{
//Main method code not relevant here, since layout function is called from run() which gets called on starting thread for this class.
}
} //Called Class NewJFrame3 end
Thanks a ton for your time!
