类org.eclipse.ui.actions.ReadOnlyStateChecker源码实例Demo

下面列出了怎么用org.eclipse.ui.actions.ReadOnlyStateChecker的API类实例代码及写法,或者点击链接到github查看源代码。

@Override

		DropTargetEvent event, Object target) {

	try {

			}
			return Status.OK_STATUS;
		}
	} 
	finally {

		// since this drop adapter did the remove of the source even
		// if we moved something.

	}
	return Status.CANCEL_STATUS;
}
