| /** |
| * An EventQueue subclass which adds selective tracing of events as they |
| * are posted to an EventQueue. Tracing is globally enabled and disabled |
| * by the AWT.TraceEventPosting property in awt.properties. <P> |
| * |
| * The optional AWT.NoTraceIDs property defines a list of AWTEvent IDs |
| * which should not be traced, such as MouseEvent.MOUSE_MOVED or PaintEvents. |
| * This list is declared by specifying the decimal value of each event's ID, |
| * separated by commas. |
