e628. Setting the Stretchyness of a Component Within the Cell of a GridBagLayout Using Fill

By default, when the cell is larger than the preferred size of a component, the component is centered within the cell. You can stretch a component horizontally or vertically, or in both directions within the cell by setting its fill constraint.

See e622 Creating a GridBagLayout for an example on how to use a gridbag layout with gridbag constraints.

    GridBagLayout gbl = new GridBagLayout();
    container.setLayout(gbl);
    
    GridBagConstraints gbc = new GridBagConstraints();
    
    // Make the component on stretchable
    gbc.fill = GridBagConstraints.NONE;
    
    // Make the component only stretch horizontally
    gbc.fill = GridBagConstraints.HORIZONTAL;
    
    // Make the component only stretch vertically
    gbc.fill = GridBagConstraints.VERTICAL;
    
    // Make the component stretch in both directions
    gbc.fill = GridBagConstraints.BOTH;
    
    gbl.setConstraints(component, gbc);
    container.add(component);
