UI 字体是 "Andale Sans UI"
查看openoffice的README文档(我的 Debian 是在 /usr/lib/openoffice/README),有关于如何替换界面字体的方法。
Changing the User Interface Font
In OpenOffice.org you can change the font used for screen display and printing by replacing it with a different font installed on your system. This can be done using the font replacement function. Choose Tools - Options - OpenOffice.org - Font Replacement to access this function.
To change the font of the OpenOffice.org user interface, you have to replace the default font "Andale Sans UI" with another font and mark the "always" setting for this replacement.
Refer to the OpenOffice.org Help for a detailed explanation of the dialog.
