Вы можете рассмотреть два основных подхода: Один из них - использовать очень гибкий менеджер раскладки, например MigLayout
.Я не знаком с этим, но я могу рекомендовать GridbagLayout для работы:
JPanel helper = new JPanel( );
GridBagLayout gbl_helper = new GridBagLayout();
gbl_helper.columnWidths = new int[]{200, 7, 200, 60, 18, 0};
gbl_helper.rowHeights = new int[]{20, 20};
gbl_helper.columnWeights = new double[]{1.0, 0.0, 1.0, 0.0, 0.0, Double.MIN_VALUE};
gbl_helper.rowWeights = new double[]{0.0, 0};
helper.setLayout(gbl_helper);
GridBagConstraints gbc1 = new GridBagConstraints();
gbc1.fill = GridBagConstraints.HORIZONTAL;
gbc1.gridwidth = 2;
gbc1.anchor = GridBagConstraints.NORTHWEST;
gbc1.insets = new Insets(5,5,5,5);
gbc1.gridx = 0;
gbc1.gridy = 0;
JButton button1 = new JButton( "Add puncta coordinates from CSV" );
helper.add( button1, gbc1 );
GridBagConstraints gbc2 = new GridBagConstraints();
gbc2.fill = GridBagConstraints.HORIZONTAL;
gbc2.gridwidth = 2;
gbc2.anchor = GridBagConstraints.NORTHWEST;
gbc2.insets = new Insets(5,5,5,5);
gbc2.gridx = 2;
gbc2.gridy = 0;
JButton button2 = new JButton( "Add track coordinates from CSV" );
helper.add( button2, gbc2 );
GridBagConstraints gbc3 = new GridBagConstraints();
gbc3.insets = new Insets(0, 0, 0, 5);
gbc3.gridx = 0;
gbc3.gridy = 1;
JLabel label = new JLabel( "Move to time:" );
helper.add( label, gbc3 );
JTextField tMoveTime = new JTextField();
tMoveTime.setColumns(15);
GridBagConstraints gbc4 = new GridBagConstraints();
gbc4.anchor = GridBagConstraints.WEST;
gbc4.insets = new Insets(0, 0, 0, 5);
gbc4.gridx = 1;
gbc4.gridy = 1;
helper.add( tMoveTime, gbc4);
JButton bMoveTime = new JButton("Move");
GridBagConstraints gbc5 = new GridBagConstraints();
gbc5.insets = new Insets(0, 0, 0, 5);
gbc5.anchor = GridBagConstraints.NORTHEAST;
gbc5.gridx = 3;
gbc5.gridy = 1;
helper.add( bMoveTime, gbc5 );
Другой подходразделить сложный макет на более простые макеты с помощью подпанелей, каждая со своим собственным менеджером макетов:
JPanel helper = new JPanel( );
helper.setLayout(new BoxLayout(helper, BoxLayout.Y_AXIS));
getContentPane().add(helper);
JPanel topPanel = new JPanel();
helper.add(topPanel);
JButton button1 = new JButton( "Add puncta coordinates from CSV" );
topPanel.add(button1);
JButton button2 = new JButton( "Add track coordinates from CSV" );
topPanel.add(button2);
JPanel bottomPanel = new JPanel();
helper.add(bottomPanel);
bottomPanel.setLayout(new BoxLayout(bottomPanel, BoxLayout.X_AXIS));
JPanel bottomRIght = new JPanel();
bottomPanel.add(bottomRIght);
JLabel label = new JLabel( "Move to time:" );
bottomRIght.add(label);
JTextField tMoveTime = new JTextField();
bottomRIght.add(tMoveTime);
tMoveTime.setColumns(15);
JPanel bottomleftPanel = new JPanel();
bottomPanel.add(bottomleftPanel);
bottomleftPanel.setLayout(new FlowLayout(FlowLayout.RIGHT, 5, 5));
JButton bMoveTime = new JButton("Move");
bottomleftPanel.add(bMoveTime);
