    Default Simple Question (hopefully)

    I have searched for a little while ('cause i find that before my thread is answered sometimes i find the answer either on my own or from Google or something) for how to set the background text for a JTextField. I have found results for how to do it on javascript... though that's not what i want. i have also looked around how to use TextFields in Oracle's tutorials.

    What i mean by background text (dont read if you know what i'm talking about):

    Say i have a TextField, and before i type anything, theres text already there(not the default text you can set when u initiate it), and when i click the cursor that text is gone....

    any help appreciated

    How I would do this:

    Start with the JTextField already containing your background text.

    Add a focus listener to the JTextField, and when someone focuses on the JTextField, clear the default text and allow the user to type as they want.

    Some things to keep in mind:

    1. Do you want the default text re-displayed if the JTextField loses focus and doesn't contain any text? In this case, you need to add the reverse operation (insert the default text when the JTextField loses focus).

    2. Use an external boolean flag to determine if the JTextField really is just displaying the background text, not actual text the user has typed in which matches the background text

    Much thanks. I like how you explain in english. It helps understand what I need to do instead of trying to figure out what the code does so I can replicate it.

    +thanks
