swing

The swing package contains additional classes which work with the Java swing package.

JCloseableTabbedPane

The JCloseableTabbedPane class is a closeable tabbed pane. It is a JTabbedPane with a close button to close each tab.

Example:

Generic dialog

The GenericDialog class is a generic dialog component, with Yes / No buttons. The minimal method to implement is the GenericDialog.createPanel() method, which allows to create the main panel of the dialog.

Example:

Dialog builder

The DialogBuilder class simplifies the creation of popup dialogs, allowing to create several rows of content, optionally enclosed in their titled borders.

Example:

File choosers

Several classes extend the Swing JFileChooser class:

• The JOptionalFileChooser class allow to present an additional button in the interface to allow to unset the file
• The UnsortableFileChooser class return the selected files in the order in which they were added by the user rather than the order chosen by the JFileChooser class
• The JFileSelector class is a file chooser backed by a component. See JFileSelector
• The JMultipleFileSelector class is a multiple file chooser backed by a component, where the order of the files is clearly specified by the user. See JMultipleFileSelector

JColorSelector

The JColorSelector class is a JColorChooser backed by a component.

Example

  JFrame f = new JFrame("test");
  f.setSize(200, 300);
  JColorSelector cs = new JColorSelector(new DefaultColorSelectionModel());
  cs.setColor(Color.lightGray);

  cs.addActionListener(new ActionListener() {
    public void actionPerformed(ActionEvent e) {
      System.out.println("Action : ");
    }
  });

  f.getContentPane().setLayout(new FlowLayout());
  f.getContentPane().add(cs);
  f.addWindowListener(new WindowAdapter() {
    @Override
    public void windowClosing(WindowEvent e) {
      System.exit(0);
    }
  });
  f.pack();
  f.setVisible(true);

Result:

JListChooser

The JListChooser class is a JList allowing to define a list of data, which can be added / removed / changed.

Example

  String[] fillValues = { "NONE", "HORIZONTAL", "VERTICAL VALUE", "BOTH" };
  JComboBox cb = new JComboBox(fillValues);
  cb.setSelectedItem("VERTICAL VALUE");

  ListChooserHandler handler = new ListChooserHandler() {
    @Override
    public Object getCurrentValue(JComponent c) {
      JComboBox cb = (JComboBox) c;
      return cb.getSelectedItem();
    }
  };
  JListChooser chooser = new JListChooser(cb, handler);

  chooser.setHandler(handler);
  chooser.setTitle("test");
  int retour = chooser.showDialog(null);
  if (retour == JListChooser.APPROVE_OPTION) {
    System.out.println("APPROVE: " + chooser.getValues().size());
  } else {
    System.out.println("CANCEL");
  }

Result:

JMultilineTextEditor

The JMultilineTextEditor class is a JTextComponent backed by a small component which can be shown on one line.


The text can be directly edited on the text field, or by editing a multiline dialog after clicking on the left button.

Note that it is possible to customize the dialog itself by overriding the JMultilineTextEditor.createMultilineDialog() method.

JListSelector

The JListSelector class is a JListChooser backed by a component.

JMemoryViewer

The JMemoryViewer class is a component which shows the memory used by the program compared to the total memory available for the JVM.

Property editor

The PropertyEditor class is a component which presents datas in a two-dimensional table format. It can be used to show and modify every types of properties.

There are only two columns in this Table:

• the left column shows the name of the property to be shown
• the right column shows the value of this property to edit. All editors managed by the ExtendedCellEditor class can be used

It extends the functionalities of the generic JTable component by allowing to:

• add every type of editor / renderer for each row, providing that they are JComponents managed by the ExtendedCellEditor class

The process of the creation of a PropertyEditor must follow these rules:

• create a new PropertyEditor
• add all the properties by the PropertyEditor.addProperty(JComponent, Object, String) method
• show the Table by the setVisible method

The component can then be used as any JPanel.

Note: Events fired by each rows are managed by the editor added in the row by the PropertyEditor.addProperty(JComponent, Object, String) method.

Extended Cell Editor

The ExtendedCellEditor class allows to put custom components in JTable cells.

Layout utilities

The LayoutUtils class propose some utilities for Swing Layouts which provide greedy Box fillers to use with the BoxLayout.
