Class SWTException

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).

      Constructs a new instance of this class with its stack trace and message filled in. The error code is set to an unspecified value. Specifying null as the message is equivalent to specifying an empty string.

      Parameters:
      code - the SWT error code
    • SWTException

      public SWTException(int code, String message)
      Constructs a new instance of this class with its stack trace, error code and message filled in. Specifying null as the message is equivalent to specifying an empty string.

    • 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.

      Overrides:
      getCause in class Throwable
      Returns:
      the underlying throwable

    • 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).

      Overrides:
      getMessage in class Throwable
      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.

      Overrides:
      printStackTrace in class Throwable
