Font editor
A Font editor in a Traits UI allows the user to select a font from the
operating system.
Typically, you then pass the Font trait to another UI editor, which uses it to
display text. You can also read the Font trait as a string, or access its
individual attributes (note that these attributes are specific to the UI
toolkit -- QT or WX.)
The default 'simple' Font editor style is usually the most useful and powerful
style - it pops up a font selection dialog which is specific to the OS and
toolkit.
This example also displays some other less common style choices.
Please refer to the `FontEditor API docs`_ for further information.
