swing里面有类似windows记事本中设置字体的组件吗？还是要自己写？

Question

各位大哥给个答案

Answer 1

没有什么现成的组建
不过也不用自己写.
你到www.chinajavaworld.com里，那里的版主sunking弄了一个OpenSwing，有很多东西
或者到google上搜一下，有很多swing不带的界面包，下一个就可以了

Answer 2

有！不过不是组件~
JEditPane里面有SetFont方法的
LZ可以去看看API~

Answer 3

hehe:)
这是我很早之前写的一个控件。

Answer 5

楼上专家的程序,能不能把FontResources.properties这个文件一起发是来?
