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).

      • SWTException

        public SWTException​(String message)
        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.

                    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.

    • 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.

        Overrides:
        getCause in class Throwable
        Returns:
        the underlying throwable
        Since:
        3.1

      • 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
