GridBagLayout

• A GridBagLayout allows arbitrary gridded arrangements
• Each component managed by a GridBagLayout has an associated GridBagLayoutConstraint to control it

  GridBagLayout gridbag = 
          new GridBagLayout();
  Button btn = new Button("Hello");
  GridBagConstraints c = 
          new GridBagConstraints();
  // set values in c ...
  gridbag.setConstraints(btn, c);
  

• A GridBagConstraints can be reused or changed for many objects
