较大的TextField Java中的较小TextField

Question

I want a textfield which looks like this :

textfield . textfield . textfield. textfield

and to enter just numbers in the textfields. Can you help me, please? :)

Answer 1

You don't need a parent textfield to act as a container for 4 textfields. Place 4 textfields inside a panel.

The steps to achieve this in java swing:
1.Create a JPanel with a white background.
2.Add 4 JTextField s seperated by JLabel with value . (Use the GridLayout to keep them in a single row).
3.Disable the highlighting of JTextField s and its border or make the textfield transparent
4.Instead add a border to the JPanel when any of the JTextfield s accepts input.
