| 46 * IMPORTANT: This class is intended to be subclassed <em>only</em> | |
| 47 * within the SWT implementation. However, it has not been marked | |
| 48 * final to allow those outside of the SWT development team to implement | |
| 49 * patched versions of the class in order to get around specific | |
| 50 * limitations in advance of when those limitations can be addressed | |
| 51 * by the team. Any class built using subclassing to access the internals | |
| 52 * of this class will likely fail to compile or run between releases and | |
| 53 * may be strongly platform specific. Subclassing should not be attempted | |
| 54 * without an intimate and detailed understanding of the workings of the | |
| 55 * hierarchy. No support is provided for user-written classes which are | |
| 56 * implemented as subclasses of this class. | |
