Java Swing Border和Boxlayout

Question

i have a Jtable and now i want to have a JLabel and a JTextField and a JButton in one row above this Jtable.

How do i do that?

until now i had this:

    final JTableHeader header = table.getTableHeader();
    setLayout(new BorderLayout());

    add(header, BorderLayout.PAGE_START);
    add(table, BorderLayout.CENTER);  

now i added this above:

    ImageIcon leftButtonIcon = createImageIcon("images/add.gif");
    JButton addButton = new JButton(leftButtonIcon);

    JLabel labelF = new JLabel("Filter:");
    labelF.setAlignmentX(Component.RIGHT_ALIGNMENT);

    JTextField eingabeF = new JTextField();
    eingabeF.setSize(50, 10);

but how to do, that there ist this: "Filter: TEXTFIELD BUTTON" and under this there is the Table ?

Answer 1

1. Add the labelF label, eingabeF text field and addButton button to an instance of JPanel with FLowLayout . And add it to the content pane(which has BorderLayout ) with constraint BorderLayout.PAGE_START . JPanel has FlowLayout as it's default layout

2. Enclose your table to an instance of JScrollPane and Then add the scroll pane to the content pane with constraint BorderLayout.CENTER . The scroll pane automatically places the table header at the top of the viewport.

    JScrollPane scrollPane = new JScrollPane(table); table.setFillsViewportHeight(true);
