addBut = new JButton("Add");
addBut.addActionListener(this);
deleteBut = new JButton("Delete");
deleteBut.addActionListener(this);

selectionPanel.setLayout(new GridLayout(2,2));
TitledBorder selectionBorder = new TitledBorder("Options");

I believe setting GridLayout(2,2) will override size changes made to the panels. To be more precise, use GridBagConStraints;
我相信设置 GridLayout(2,2) 将覆盖对面板所做的大小更改。更准确地说，使用 GridBagConStraints；
private JTextField field1 = new JTextField();
private JButton addBtn = new JButton("Save: ");
public void addComponents(Container pane) {
pane.setLayout(new GridBagLayout());
GridBagConstraints c = new GridBagConstraints();
// Components
c.gridwidth = 1;
c.weightx = .01;
c.weighty = .2;
c.gridx = 0;
c.gridy = 1;
pane.add(field1, c);
c.gridwidth = 1;
c.weightx = .01;
c.weighty = .2;
c.gridx = 0;
c.gridy = 1;
pane.add(addBtn, c);
}
public MainView() {
//Create and set up the window.
JFrame frame = new JFrame("NAME");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//Set up the content pane.
addComponents(frame.getContentPane());
//Display the window.
frame.pack();
frame.setVisible(true);
frame.setResizable(false);
frame.setSize(400, 125);
frame.setLocation(400, 300);
}
