类名称：Device
方法名：getSystemFont

Device.getSystemFont介绍

[英]Returns a reasonable font for applications to use. On some platforms, this will match the "default font" or "system font" if such can be found. This font should not be freed because it was allocated by the system, not the application.

Typically, applications which want the default look should simply not set the font on the widgets they create. Widgets are always created with the correct default font for the class of user-interface component they represent.
[中]返回应用程序要使用的合理字体。在某些平台上，这将与“默认字体”或“系统字体”匹配（如果可以找到）。不应释放此字体，因为它是由系统而不是应用程序分配的。
通常，想要默认外观的应用程序不应该在它们创建的小部件上设置字体。小部件总是使用它们所代表的用户界面组件类的正确默认字体创建。
