How can I control the width of JTextFields in Java Swing?

Question

I am trying to have several JTextFields on a single row, but I don\'t want them to have the same width. How can I control the width and make some of them wider than others?

Answer 1

Try this:

textfield.setPreferredSize(new Dimension(int width, int height));

Answer 2

All Swing components have a preferred size. The preferred size of a text component is based on the text of the component. So generally the component is painted at its preferred size.

So I don't see the problem with your code snippet. Each text field should have a different preferred size. Also, as the frame is resized the width will be adjusted since the BoxLayout will try to resize each component up to its maximum/minimum size.

If you need more help post your SSCCE that actually demonstrates the sizing problem you are experiencing.

Edit:

Based on the latest requirement you can use the Relative Layout.

Answer 3

yourTextField = new JTextField("", 20);

if you start it like this it sets the textfield to be empty and to have 20 collumns

Answer 4

// 1. create JTextField
yourTextField = new JTextField();
// 2. store default height
int defaultHeight = yourTextField.getSize().getHeight();
// 3. set custom width and default height
yourTextField.setSize(new Dimension(yourWidth, defaultHeight));
