public class PrefPanel
extends javax.swing.JPanel

Create a User Preferences Panel or Dialog. A PrefPanel manages a set of Fields with convenience methods for rapidly creating User Dialogs whose values are made persistent by a Preferences Store. All Fields contained in the PrefPanel share the same Preferences, and so must have unique names. Send ActionEvent when "accept" button is pressed. Can also listen on individual Fields. You must call one finish() method exactly once, when you are done adding Fields.

Example of use:

    PreferencesExt store = null;
    try {
      xstore = XMLStore.createFromFile("E:/dev/prefs/test/panel/panel.xml", null);
      store = xstore.getPreferences();
    } catch( Exception e) {
      System.out.println(e);
      System.exit( 1);
    }
    PrefPanel pp = new PrefPanel("test", store);
    pp.addTextField("name", "name", "defValue");
    pp.newColumn();
    pp.addTextField("name2", "name2", "defValue22");
    pp.newColumn();
    pp.addTextField("name3", "name3", "defValue22 asd jalskdjalksjd");
    pp.finish();

    pp.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
        // accept was called
      }
    });
  

Form layout

The PrefPanel is layed out with the jgoodies FormLayout layout manager and PanelBuilder, which use a row, colummn grid. Fields in the same column are aligned.

There are 2 ways to do form layout: implicit and explicit. With implicit, the position is implicitly specified by the order the fields are added, using, for example:

  addDoubleField(String fldName, String label, double defValue) 

The fields are all added in a column. To start a new column, use setCursor().

With explicit, you specify the row and col, and an optional constraint:

  addDoubleField(String fldName, String label, double defValue, int col, int row, String constraint) 

Row and column numbers are 0 based. Each field has a width of 2 columns (one for the label and one for the component) and a height of 1 row, unless you specify otherwise using a constraint. A heading takes up an entire row, spanning all columns
