+/**
+ * The Assets class allows assets such as images and property files to be
+ * combined into zip files rather than delivered individually. The Assets
+ * instance is a singleton served by a set of static methods. In particular, the
+ * three add(...) methods are used to create asset references, which include an
+ * arbitrary name, a path to a zip file asset, and one or more class paths that
+ * are covered by this zip file asset.
+ *
+ * For example:
+ *
+ * <code>
+ static {
+ try {
+ Assets.add(new Assets.Asset("osp", "osp-assets.zip", "org/opensourcephysics/resources"));
+ Assets.add(new Assets.Asset("tracker", "tracker-assets.zip",
+ "org/opensourcephysics/cabrillo/tracker/resources"));
+ Assets.add(new Assets.Asset("physlets", "physlet-assets.zip", new String[] { "opticsimages", "images" }));
+ // add the Info.assets last so that it can override these defaults
+ if (OSPRuntime.isJS) {
+ Assets.add(OSPRuntime.jsutil.getAppletInfo("assets"));
+ }
+ } catch (Exception e) {
+ OSPLog.warning("Error reading assets path. ");
+ }
+
+ }
+ * </code>
+ *
+ * It is not clear that Java is well-served by this zip-file loading, but
+ * certainly JavaScript is. What could be 100 downloads is just one, and SwingJS
+ * (but not Java) can cache individual ZipEntry instances in order to unzip them
+ * independently only when needed. This is potentially a huge savings.
+ *
+ * Several static methods can be used to retrieve assets. Principal among those
+ * are:
+ *
+ * <code>
+ * getAssetBytes(String fullPath)
+ * getAssetString(String fullPath)
+ * getAssetStream(String fullPath)
+ * </code>
+ *
+ * If an asset is not found in a zip file, then it will be loaded from its fullPath.

+package javajs.async;
+
+/**
+ * A package to manage asynchronous aspects of SwingJS
+ *
+ * The javajs.async package simplifies the production of methods that can be
+ * used equally well in Java and in JavaScript for handling "pseudo-modal"
+ * blocking in JavaScript, meaning the user is locked out of other interactions,
+ * as in Java, but the code is not actually blocking the thread.
+ *
+ * Included in this package are
+ *
+ * Async
+ *
+ * Provides few simple generic static methods.
+ *
+ * Async.isJS() -- true if we are running this in JavaScript
+ *
+ * Async.javaSleep() -- bypassing Thread.sleep() for JavaScript; allowing it for
+ * Java
+ *
+ *
+ * AsyncDialog
+ *
+ * Provides several very useful methods that act as a replacement for direct
+ * JOptionPane or JDialog calls, including both a synchronous callback
+ * (manifested in Java) and an asynchronous callback (JavaScript), both
+ * resulting in the same effect, except for the fact that the JavaScript code
+ * has returned immediately from the call with an "ignore me" reference, while
+ * Java is waiting at that call to return a value from JOptionPane (which is
+ * saved by AsyncDialog and not delivered as a return value).
+ *
+ * AsyncDialog does not extend JOptionPane, but it mirrors that classes public
+ * methods. There are a LOT of public methods in JOPtionPane. I suppose we
+ * should implement them all. In practice, AsyncDialog calls standard
+ * JOptionPane static classes for the dialogs.
+ *
+ * Initially, the following methods are implemented:
+ *
+ * public void showConfirmDialog(Component frame, Object message, String title,
+ * ActionListener a)
+ *
+ * public void showConfirmDialog(Component frame, Object message, String title,
+ * int optionType, ActionListener a)
+ *
+ * public void showConfirmDialog(Component frame, Object message, String title,
+ * int optionType, int messageType, ActionListener a)
+ *
+ * public void showInputDialog(Component frame, Object message, ActionListener
+ * a)
+ *
+ * public void showInputDialog(Component frame, Object message, String title,
+ * int messageType, Icon icon, Object[] selectionValues, Object
+ * initialSelectionValue, ActionListener a)
+ *
+ * public void showMessageDialog(Component frame, Object message, ActionListener
+ * a)
+ *
+ * public void showOptionDialog(Component frame, Object message, String title,
+ * int optionType, int messageType, Icon icon, Object[] options, Object
+ * initialValue, ActionListener a)
+ *
+ *
+ * All nonstatic methods, requiring new AsyncDialog(), also require an
+ * ActionListener. This listener will get a call to actionPerformed(ActionEvent)
+ * where:
+ *
+ * event.getSource() is a reference to the originating AsyncDialog (super
+ * JOptionPane) for all information that a standard JOptionPane can provide,
+ * along with the two methods int getOption() and Object getChoice().
+ *
+ * event.getID() is a reference to the standard JOptionPane int return code.
+ *
+ * event.getActionCommand() also holds a value, but it may or may not be of
+ * value.
+ *
+ *
+ * A few especially useful methods are static, allowing just one or two expected
+ * callbacks of interest:
+ *
+ * AsyncDialog.showOKAsync(Component parent, Object message, String title,
+ * Runnable ok)
+ *
+ * AsyncDialog.showYesAsync (Component parent, Object message, String title,
+ * Runnable yes)
+ *
+ * AsyncDialog.showYesNoAsync (Component parent, Object message, String title,
+ * Runnable yes, Runnable no)
+ *
+ * These methods provide a fast way to adjust JOptionPane calls to be
+ * asynchronous.
+ *
+ *
+ *
+ * AsyncFileChooser extends javax.swing.JFileChooser
+ *
+ * Accepted constructors include:
+ *
+ * public AsyncFileChooser()
+ *
+ * public AsyncFileChooser(File file)
+ *
+ * public AsyncFileChooser(File file, FileSystemView view)
+ *
+ * (Note, however, that FileSystemView has no equivalent in JavaScript.)
+ *
+ * It's three public methods include:
+ *
+ * public void showDialog(Component frame, String btnLabel, Runnable ok,
+ * Runnable cancel)
+ *
+ * public void showOpenDialog(Component frame, Runnable ok, Runnable cancel)
+ *
+ * public void showSaveDialog(Component frame, Runnable ok, Runnable cancel)
+ *
+ *
+ * ActionListener is not needed here, as the instance of new AsyncFileChooser()
+ * already has direct access to all the JFileChooser public methods such as
+ * getSelectedFile() and getSelectedFiles().
+ *
+ * As a subclass of JFileChooser, it accepts all three public showXXXX methods
+ * of JFileChooser, namely:
+ *
+ * public void showDialog(Component frame, String btnLabel)
+ *
+ * public void showOpenDialog(Component frame)
+ *
+ * public void showSaveDialog(Component frame)
+ *
+ *
+ * None of these are recommended. AsyncFileChooser will indicate errors if the
+ * first of these two are called. (showSaveDialog is fine, as it is modal even
+ * in JavaScript. However it is not recommended that showSaveDialog(Component
+ * frame) be used, as in the future browsers may implement some sort of file
+ * saver in HTML5.
+ *
+ *
+ *
+ * AsyncColorChooser
+ *
+ *
+ * AsyncColorChooser accesses JColorChooser asynchronously, using a private
+ * SwingJS setting that tells JColorChooser to report back to it with property
+ * changes. It is constructed using new AsyncColorChooser() and implements just
+ * two methods:
+ *
+ * public void showDialog(Component component, String title, Color initialColor,
+ * ActionListener listener)
+ *
+ * public Color getSelectedColor()
+ *
+ *
+ * The listener will get an actionPerformed(ActionEvent) callback with
+ * event.getID() equal to the color value or 0 if canceled. The
+ * getSelectedColor() method may also be called from this callback to retrieve
+ * the associated java.awt.Color object, using
+ *
+ * ((AsyncColorChooser)e.getSource()).getSelectedColor()
+ *
+ * As in Java, a null value for the selected color indicates that the
+ * JColorChooser was closed.
