| /** |
| * hack for issue #67799, on macosx with single button mouse, |
| * make Ctrl-Click work as right click on multiselections |
| * |
| * Also handles issue #90371 - on Macintosh, JTextComponents |
| * are never sent focus lost events, resulting in multiple |
| * blinking carets. Hack tracks last known JTextComponent |
| * and sets its cursor to invisible if any other component |
| * gains focus (on Mac OS, getOppositeComponent() |
| * frequently returns null when coming from a JTextComponent) |
