public class SWTException

extends java.lang.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).
