Focus/not focus only changes background color.
If it is gray and set foreground color to gray... sure you wont see the text anymore the foreground and background colors are the same.
Don't understand your question.... "The word change to none"
"How to do this?" How to do what ?

Initialization state.
txt1 is set a Text "Hello World" and it in GRAY foreground color.
After the user click on the txt1 field
The txt1 become Black froreground color, then the "Hello World" text disappear. The txt1 waiting for user to input new string.

import java.awt.*;
import javax.swing.*;
public class TField extends JFrame {
TField() {
super("TextField test");
setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
setSize(300, 150);
JTextField t = new JTextField("Hello World");
t.setForeground(Color.GRAY);
add(t, BorderLayout.CENTER);
// just to have 2 elements who can have focus
add(new JButton("OK"), BorderLayout.SOUTH);
setVisible(true);
}
public static void main(String[] args) {
new TField();
}
}
TextField appears with ForegroundColor gray
When we click on it
Hello World stays there
the cursor appears in the JTextField

Only have one component...
No need the Button appear there....
I think have to implements MouseListener.....
Remember only one Component ie ONE TEXTFIELD
Thank you

If also works without the button. I just added the button so I can change to see if what happens when the focus changes. Could not reproduce the behaviour you are experiencing. May be you will have to post your code.

Now it still researching for solution yet.
My coding a bit similar as yours.
Now I thinking how the Frame can detect which components are actived?
Do you know how?
Just say, the frame has JTEXTFIELD, JBUTTON, CHECKBOX....
When user click or tab either component, we will see the active message by using System.out.println("MSG");,
Example "USer click on JButton", "USer Click on CHeckBOX1", "USer Click on JTExtField".
Last time I got saw this tutorial. But now I have to retrieve it back....At that time I not save the URL down.
Thanks.....
