Thread: how to avoid flickering when calling another swing from

Hi,

I am trying to call another swing frame from my current frame. And after calling second frame i dispose the current frame.
But while second frame comming on the screen, current frame gets dispose and second frame takes some seconds to appear on screen.
So its creating a bad flickering effect on screen and its not suitable for my application.

i want that first frame will call sencond frame and it will not look like second frame is called. I just want to cancel flickering effect.

Here is my source code.
1st Frame:

public class Welcome extends JFrame
{
JFrame f;
JTextArea nameField,nameField1;
JLabel lable;


public Welcome() throws IOException, ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException, InterruptedException
{
f=new JFrame();
lable.setLayout(null );

/*****heading text WELCOME*****/
nameField = new JTextArea("Welcome");

nameField.setBounds(320,370,650,150);
nameField.setForeground(new Color(6,42,120));
nameField.setFont(new Font("Caladea", Font.BOLD, 55 ));
nameField.setOpaque(false);
nameField.setEditable(false);

nameField1 = new JTextArea("Here");
nameField1.setBounds(170,470,750,150);
nameField1.setForeground(new Color(6,42,120));
nameField1.setFont(new Font("Caladea", Font.BOLD, 55 ));
nameField1.setOpaque(false);
nameField1.setEditable(false);

lable.add(nameField);
lable.add(nameField1);

f.add(lable);
f.setResizable(false);
f.setUndecorated(true);
f.validate();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
GraphicsEnvironment.getLocalGraphicsEnvironment(). getDefaultScreenDevice().setFullScreenWindow(f);
f.setVisible(true);

Thread.sleep(3000);
PBEnter pe = new PBEnter();
}
public static void main(String[] args) throws IOException, ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException, InterruptedException
{
new Welcome();
}
}



2nd Frame:

public class PBEnter {

JFrame f;
JTextArea nameField1,nameField2,nameField3;
JLabel lable;

public PBEnter() throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException, IOException, InterruptedException
{

f=new JFrame();

nameField1 = new JTextArea("Enter Ur Name");
nameField1.setBounds(200,350,650,150);
nameField1.setForeground(new Color(6,42,120));
nameField1.setFont(new Font("Caladea", Font.BOLD, 50));
nameField1.setOpaque(false);
nameField1.setEditable(false);

nameField2 = new JTextArea("Middle Name");
nameField2.setBounds(230,450,650,150);
nameField2.setForeground(new Color(6,42,120));
nameField2.setFont(new Font("Caladea", Font.BOLD, 50));
nameField2.setOpaque(false);
nameField2.setEditable(false);

nameField3 = new JTextArea("Sirname");
nameField3.setBounds(400,550,650,150);
nameField3.setForeground(new Color(6,42,120));
nameField3.setFont(new Font("Caladea", Font.BOLD, 50));
nameField3.setOpaque(false);
nameField3.setEditable(false);

lable.setLayout(null );

lable.add(nameField1);
lable.add(nameField2);
lable.add(nameField3);

f.add(lable);
f.setResizable(false);
f.setUndecorated(true);
f.validate();
f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
GraphicsEnvironment.getLocalGraphicsEnvironment(). getDefaultScreenDevice().setFullScreenWindow(f);
f.setVisible(true);

Thread.sleep(3000);

Registration r = new Registration();
f.dispose();
}

public static void main(String[] args) throws IOException, ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException, InterruptedException
{

}
}

Please post your code correctly per the instructions that were given you in response to your first post.

when second screen is called it comes up like a pop up on the screen. But i want Smooth navigation within my pages.
I am using Linux Puppy as OS. And JRE 1.7 version.

The delay is the time it takes to actually create the frame. Your computer is too slow to make it smoother.
There are 2 things you can do:
1) Have the first frame wait until the second one is displayed, possibly with busy-waiting. This is not nice and I would not recommend it, but its easy to do.

2) Dont create a second frame. Instead, clear your first frame and fill it up with new components. This will probably need some refactoring to clean up references.
