| 24 | /** | |
| 25 | * Context menu finder that uses events to get the current context menu. It must be used instead of ContextMenuFinder | |
| 26 | * when the context menu is not associated with a Widget. It must be registered before the context menu appears. | |
| 27 | * <p> | |
| 28 | * Here is a sample usage: | |
| 29 | * </p> | |
| 30 | * | |
| 31 | * <pre> | |
| 32 | * EventContextMenuFinder eventContextMenuFinder = new EventContextMenuFinder(); | |
| 33 | * try { | |
| 34 | * eventContextMenuFinder.register(); | |
| 35 | * button.click(); // a popup menu appears below the button | |
| 36 | * SWTBotMenu menu = new SWTBotMenu(new Finder(new ControlFinder(), eventContextMenuFinder), "Menu Text"); | |
| 37 | * menu.click(); | |
| 38 | * } finally { | |
| 39 | * eventContextMenuFinder.unregister(); | |
| 40 | * } | |
| 41 | * </pre> | |
| 42 | * | |
| 43 | * This is not convenient to use but the need for this is not so frequent. In case you have better idea on the | |
| 44 | * implementation or usage please add a comment to <a href="http://swtbot.org/bugzilla/show_bug.cgi?id=19">this bug</a>. | |
