public class SWTException extends RuntimeException
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 athrowable
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).

getCause
public Throwable getCause()
Returns 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.

Returns 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:
getMessage
in classThrowable
- Returns:
- the error message string of this SWTException object
-
printStackTrace
public void printStackTrace()

- Overrides:
printStackTrace
in classThrowable
