/**
 * 

JXErrorPane is a common error component suitable for displaying errors, * warnings, and exceptional application behavior to users.

* *

User interaction with the JXErrorPane includes the ability to * view details associated with the error. This is the primary feature that differentiates * JXErrorPane from JOptionPane. In addition, * JXErrorPane specializes in handling unrecoverable errors. If you * need an error dialog that allows the user to take some action to recover * from an error (such as "Repair Disk", "Replace All", etc) then you should * use JOptionPane.

* *

Data and application state associated with an error are encapsulated * in the {@link org.jdesktop.swingx.error.ErrorInfo} class. The * {@code JXErrorPane} displays the data contained in the {@code ErrorInfo}. * In addition, {@code ErrorInfo} is passed to the * {@link org.jdesktop.swingx.error.ErrorReporter} if the user decides to report * the incident.

* *

Basic Usage

*

Typically, the JXErrorPane * is not created and displayed directly. Instead, one of the static showXXX methods * are called that create and display the JXErrorPane in a * JDialog, JFrame, or JInternalFrame.

* *

These static showXXX methods all follow the same pattern, namely ( * where XXX could be one of Dialog, Frame, or InternalFrame): *

    *
  • showXXX(Throwable e): This usage allows you to show a default error * window, detailing the error
  • *
  • showXXX(Component owner, ErrorInfo info): This usage shows an * error dialog based on the given ErrorInfo. The component * argument is the component over which the dialog should be centered.
  • *
  • showXXX(Component owner, JXErrorPane pane): This usage shows * an error dialog using the given error pane. This allows you to completely * modify the pane (perhaps installing a custom UI delegate, etc) to present * to the user
  • *
  • createXXX(Component owner, JXErrorPane pane): Creates and returns * a dialog for presenting the given JXErrorPane, but does not * show it. This allows the developer to modify properties of the dialog * prior to display
  • *

* *

Following are some examples and further discussion regarding some of these * static methods. Example of the most basic usage: *


 *      try {
 *          //do stuff.... something throws an exception in here
 *      } catch (Exception e) {
 *          JXErrorPane.showDialog(e);
 *      }
 * 
. Alternatively there are showFrame and * showInternalFrame variants of each of the showDialog * methods described in this API.

* *

While this is the simplest usage, it is not the recommended approach for * most errors since it yields the most difficult messages for users to understand. * Instead it is recommended to provide a more useful message for users. For example: *


 *      URL url = null;
 *      try {
 *          url = new URL(userSuppliedUrl);
 *      } catch (MalformedURLException e) {
 *          String msg = "The web resource you entered is not formatted"
 *                      + " correctly.";
 *          String details = "<html>Web resources should begin with \"http://\""
 *                      + " and cannot contain any spaces. Below are a few"
 *                      + " more guidelines.<ul>"
 *                      + getURLGuidelines()
 *                      + "</ul></html>";
 *          JXErrorPane.showDialog(myWindow, "Unknown Resource", msg, details, e);
 *          return false;
 *      }
 * 

* *

Before showing the JXErrorPane in a frame or dialog, you may modify * the appearance and behavior of the JXErrorPane by setting one or more of its bean * properties. For example, to modify the icon shown with a particular * instance of a JXErrorPane, you might do the following: *


 *      JXErrorPane pane = new JXErrorPane();
 *      pane.setErrorIcon(myErrorIcon);
 *      pane.setErrorInfo(new ErrorInfo("Fatal Error", exception));
 *      JXErrorPane.showDialog(null, pane);
 * 

* *

JXErrorPane may also be configured with a "Report" button which allows * the user to send a bug report, typically through email. This is done through * the pluggable {@link org.jdesktop.swingx.error.ErrorReporter} class. Simply instantiate * some custom subclass of ErrorReporter and pass the instance into the * {@link #setErrorReporter} method.

* *

JXErrorPane can also be used for displaying fatal error messages to * users. Fatal messages indicate a serious error in the application that cannot * be corrected and that must result in the termination of the application. * After the close of a fatal error dialog, the application should * automatically exit. Fatal messages are identified by the Level * of the ErrorInfo being * {@link org.jdesktop.swingx.error.ErrorLevel}.FATAL.

* *

By default, when Fatal error dialogs are closed the application exits with * a code of "1". In other words, System.exit(1). If you wish to implement * custom handling, you can replace the default fatal action in the ActionMap * of the JXErrorPane instance. If you specify a custom fatal * action, then the default action of calling * System.exit will not occur. You are therefore responsible for shutting down * the application.

* *
