public class SWT
extends Object

This class provides access to a small number of SWT system-wide methods, and in addition defines the public constants provided by SWT.

By defining constants like UP and DOWN in a single class, SWT can share common names and concepts at the same time minimizing the number of classes, names and constants for the application programmer.

Note that some of the constants provided by this class represent optional, appearance related aspects of widgets which are available either only on some window systems, or for a differing set of widgets on each window system. These constants are marked as HINTs. The set of widgets which support a particular HINT may change from release to release, although we typically will not withdraw support for a HINT once it is made available.

error

public static void error(int code)
Throws an appropriate exception based on the passed in error code.
Parameters:
code - the SWT error code

error

public static void error(int code,
                         Throwable throwable)
Throws an appropriate exception based on the passed in error code. The throwable argument should be either null, or the throwable which caused SWT to throw an exception.

In SWT, errors are reported by throwing one of three exceptions:

java.lang.IllegalArgumentException
thrown whenever one of the API methods is invoked with an illegal argument
org.eclipse.swt.SWTException (extends java.lang.RuntimeException)
thrown whenever a recoverable error happens internally in SWT
org.eclipse.swt.SWTError (extends java.lang.Error)
thrown whenever a non-recoverable error happens internally in SWT
This method provides the logic which maps between error codes and one of the above exceptions.

Parameters:
code - the SWT error code.
throwable - the exception which caused the error to occur.
