Usage of Jtextarea in JTable

I have a JTABLE with three columns. First column is textfield, the Second and third is JTextarea.. Using tab key I can navigate from one cell to another.

How I will set that color.? Please give some suggestions..

Thanks in Advance Vishwa

Solution

  • Create a Color object and invoke the setBackground(Color) method on your JTextArea, after checking if it has focus using the hasFocus().

    For example:

            JTextArea area = new JTextArea();
        Color c = Color.CYAN;

        if(area.hasFocus())
        {
            area.setBackground(c);
        }

    Don't forget to save the original color of the (accessible by calling area.getBackground()) before you change it, and to set it back to this when it loses focus.
