Class SWTException
java.lang.Object
java.lang.Throwable
java.lang.Exception
java.lang.RuntimeException
org.eclipse.swt.SWTException
- All Implemented Interfaces:
- Serializable
This runtime exception is thrown whenever a recoverable error
 occurs internally in SWT. The message text and error code 
 provide a further description of the problem. The exception
 has a 
throwable field which holds the underlying
 exception that caused the problem (if this information is
 available (i.e. it may be null)).
 SWTExceptions are thrown when something fails internally, but SWT is left in a known stable state (eg. a widget call was made from a non-u/i thread, or there is failure while reading an Image because the source file was corrupt).

Method Details- 
getCauseReturns the underlying throwable that caused the problem, or null if this information is not available.NOTE: This method overrides Throwable.getCause() that was added to JDK1.4. It is necessary to override this method in order for inherited printStackTrace() methods to work. 
- 
getMessageReturns the string describing this SWTException object.It is combined with the message string of the Throwable which caused this SWTException (if this information is available). - Overrides:
- getMessagein class- Throwable
- Returns:
- the error message string of this SWTException object
 
- 
printStackTracepublic void printStackTrace()Outputs a printable representation of this exception's stack trace on the standard error stream.Note: printStackTrace(PrintStream) and printStackTrace(PrintWriter) are not provided in order to maintain compatibility with CLDC. - Overrides:
