Java:创建滚动子菜单 [英] Java: Creating a scrolling submenu

问题描述

我有一个程序，其中在特定子菜单下列出了大量项目.我正在寻找一种滚动浏览它们的方法，因为菜单现在比屏幕大.以前我见过顶部和底部图标是箭头的菜单，当鼠标悬停在上面时，分别向上或向下滚动.有人可以向我解释如何做到这一点吗?或者只是如何向我的子菜单添加滚动条?

I have a program in which I have a large amount of items listed under a specific submenu. I am looking for a way to scroll through them, as the menu is now larger then the screen. Previously i have seen menus in which the top and bottom icons are arrows which, when the mouse hovers over, scroll up or down respectively. Can someone please explain to me how to do this? Or else simply how to add a scrollbar to my submenu?

谢谢！
