SystemFont
==========
**继承：** :ref:`Font<class_Font>` **<** :ref:`Resource<class_Resource>` **<** :ref:`RefCounted<class_RefCounted>` **<** :ref:`Object<class_Object>`
从系统字体加载的字体。如果未在宿主操作系统上实现，则回退到默认主题字体。
.. rst-class:: classref-introduction-group
描述
----
**SystemFont** 会从系统字体中加载一个字体，该字体是名称能与 :ref:`font_names<class_SystemFont_property_font_names>` 匹配的第一个字体。
会尝试匹配字体样式，但是并不保证。
返回的字体可能属于某个字体合集，也可能是设置了 OpenType“字重”“宽度”和/或“斜体”特性的可变字体。
你可以创建系统字体的 :ref:`FontVariation<class_FontVariation>`\ ，以便对其特征进行精细控制。
\ **注意：**\ 这个类在 iOS、Linux、macOS、Windows 上实现，在其他平台上会回退到默认主题字体。
