Not able to edit width of JTextField in JFrame with Border Layout

Thank you all who helped me on JTextField Issue. I got JTextField successfully added to my frame with Border Layout by using BorderLayout.PAGE_START. But now i am not able to edit the width of JTextField .Only height is changing. Please have a look at the underlined line.[This changes height of JTextField, but width is not changing].

JFrame with fully stretched TextField

Is border layout stretches all components to its maximum width?

Don't use setPreferredSize() like this, because you don't know how big the font will be. Do like this instead.

Edit: I forgot about BorderLayout.PAGE_START, so just use the FlowLayout of a new JPanel(); it uses the text field's built-in preferred size.

JTextField textField = new JTextField(10);
JPanel panel = new JPanel();
panel.add(textField);
frame.add(panel, BorderLayout.PAGE_START);
...
frame.pack();
frame.setVisible(true);
