Class SWTException

              extended by

All Implemented Interfaces:
Serializable

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 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).

Since:
1.0

Method Detail

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 underlying throwable
Since:
1.0

getMessage

public 
String getMessage()
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).

Returns:
the error message string of this SWTException object

printStackTrace

public 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.
