how to reposition JButton on resizing the window

Question

I have kept a JButton in the bottom middle part of my JFrame. Now whenever I resize the window the JButton should be repositioned (in the new centre) depending on new resized window. Can anyone tell me how to accomplish this. Thanks in advance.

Answer 1

Components in Swing are rendered according to the frame's layout manager. The default layout manager is BorderLayout, which divides the frame into five logical parts: North (up), South (down), East (right), West (left) and Center (everything in between). Components are centered by default.

You can create subframes for each part, and give them the a similar layout manager, or a completely different layout manager. in your case you'd want to create a new subframe at the South position of the main frame, and put your button in one of its North, Center or South positions.

Hope this helps...

Answer 2

1) Create a JPanel usign a FlowLayout with "center alignment" and add your JButton to the panel. 2) Add this panel to the "SOUTH" of the content pane which uses a BorderLayout by default.
