# Objective Remove the `new_with_` prefixes from the `TextLayout` constuctor functions. Generally, the "new" part is redundant and "with" is used by fluent APIs. ## Solution Just delete the prefixes, shorten the names (all on `TextLayout`). * `new_with_justify` -> `justify` * `new_with_linebreak` -> `linebreak` * `new_with_no_wrap` -> `no_wrap`

//! This example demonstrates generic font families,
|
|
//! which allow font faces to be selected using broadly defined
|
|
//! categories (such as serif or monospace) without selecting
|
|
//! a specific font family.
|
|
//!
|
|
//! Each generic font family is first resolved to a concrete
|
|
//! family name, which is then matched to a font in the internal
|
|
//! font database. This example loads system installed fonts to
|
|
//! populate the database.
|
|
//!
|
|
//! This feature is most useful for non-game applications;
|
|
//! most games instead choose to simply bundle their required fonts
|
|
//! to ensure a unified visual look.
