Fantom-text in jTextField. How?

We come across some popular sites login screen, where a faint gray Username is written in username textbox. I wonder can be this implemented in java swings?

I have theories, implementing by mouseEvents. Couldn't figure out how to to.

Solution

  • Check out Text Prompt.

    It allows you to display text and/or icon as a prompt for the usage of the text field. The prompt will be removed as soon as any characters are entered into the text field.

    You can also control when the prompt is displayed:

    1. ALWAYS – the prompt is displayed whether the text field has focus or not.
    2. FOCUS_GAINED – the prompt is displayed when the text field gains focus (and is hidden when focus is lost)
    3. FOCUS_LOST – the prompt is displayed when the text field loses focus (and is hidden when focus is gained)
