| 21 * This error is thrown whenever an unrecoverable error | |
| 22 * occurs internally in SWT. The message text and error code | |
| 23 * provide a further description of the problem. The exception | |
| 24 * has a <code>throwable</code> field which holds the underlying | |
| 25 * throwable that caused the problem (if this information is | |
| 26 * available (i.e. it may be null)). | |
| 27 * <p> | |
| 28 * SWTErrors are thrown when something fails internally which | |
| 29 * either leaves SWT in an unknown state (eg. the o/s call to | |
| 30 * remove an item from a list returns an error code) or when SWT | |
| 31 * is left in a known-to-be-unrecoverable state (eg. it runs out | |
| 32 * of callback resources). SWTErrors should not occur in typical | |
| 33 * programs, although "high reliability" applications should | |
| 34 * still catch them. | |
| 35 * </p><p> | |
| 36 * This class also provides support methods used by SWT to match | |
| 37 * error codes to the appropriate exception class (SWTError, | |
| 38 * SWTException, or IllegalArgumentException) and to provide | |
| 39 * human readable strings for SWT error codes. | |
