想用java做一个像windows里一样的txt编辑软件，涉及到字体设置选项卡，在网上找了很久都没找到，就生气啦自己写一个，现在贴这里分享一下，下次再遇到这样的问题就不用自己亲自打代码啦！![[JAVA] java仿windows 字体设置选项卡](https://image.shishitao.com:8440/aHR0cHM6Ly93d3cuaXRkYWFuLmNvbS9nby9hSFIwY0RvdkwybHRZV2RsY3k1amJtbDBZbXh2Wnk1amIyMHZZbXh2Wnk4MU1EWXpOekF2TWpBeE5EQXlMekU0TVRrME56RXhNell4T1RNek1TNXdibWM9.jpg?w=700 "[JAVA] java仿windows 字体设置选项卡")
