Class ExceptionDialog

java.lang.Object
eu.svjatoslav.commons.gui.dialog.ExceptionDialog
public class ExceptionDialog extends Object
A graphical dialog for displaying exceptions with stack traces.

This Swing-based dialog provides a user-friendly way to display exceptions and their stack traces in graphical applications. It shows:

  • Exception type (class name)
  • Error message
  • Cause message (if available)
  • Complete stack trace

Example usage:


 try {
     // some operation that might fail
 } catch (Exception e) {
     new ExceptionDialog(e);
 }

The dialog opens a new JFrame window with the exception details. The window is 800x600 pixels and centered on screen.

Note: This class requires a graphical environment and Swing libraries. It is not suitable for headless or server-side applications. For non-graphical error reporting, use standard logging or console output instead.
