//! Text widget, properties and other types.
//!
//! The [`Text!`] widget implements text layout and rendering, it is also the base widget for
//! [`SelectableText!`], [`TextInput!`] and [`label!`]. Text properties are largely contextual,
//! you can set `text::font_size` in any widget to affect all text inside that widget.
//!
//! The `Text!` widget provides *simple* text rendering, that is all text is of the same style and
//! different fonts are only used as fallback. You can implement *rich* text by combining multiple
//! `Text!` and `Wrap!` panels, see the [`wrap`] module docs for an example. Some widgets also parse
//! text and generate the rich text setup automatically, the [`Markdown!`] and [`AnsiText!`] widgets
//! are examples of this.
//!
//! The example below declares two text widgets, one displays a text that requires multiple fonts to render,
//! the other displays debug information about the first.
//!
//! ```
//! use zng::prelude::*;
//! # let _scope = APP.defaults();
//!
//! let txt = "text ใƒ†ใ‚ญใ‚นใƒˆ ๐Ÿ“‹";
//! let font_use = var(vec![]);
//! # let _ =
//! Stack! {
//!     text::font_family = ["Segoe UI", "Yu Gothic UI", "Segoe Ui Emoji", "sans-serif"];
//!     children = ui_vec![
//!         Text! {
//!             font_size = 1.5.em();
//!             txt;
//!             get_font_use = font_use.clone();
//!         },
//!         Text! {
//!             font_size = 0.9.em();
//!             txt = font_use.map(|u| {
//!                 let mut r = Txt::from("");
//!                 for (font, range) in u {
//!                     use std::fmt::Write as _;
//!                     writeln!(&mut r, "{} = {:?}", font.face().family_name(), &txt[range.clone()]).unwrap();
//!                 }
//!                 r.end_mut();
//!                 r
//!             });
//!         },
//!     ];
//!     direction = StackDirection::top_to_bottom();
//!     spacing = 15;
//! }
//! # ;
//! ```
//!
//! Note that the [`font_family`](fn@font_family) is set on the parent widget, both texts have the same
//! font family value because of this, the [`font_size`](fn@font_size) on the other hand is set for
//! each text widget and only affects that widget.
//!
//! [`Text!`]: struct@Text
//! [`SelectableText!`]: struct@crate::selectable::SelectableText
//! [`TextInput!`]: struct@crate::text_input::TextInput
//! [`label!`]: struct@crate::label::Label
//! [`Markdown!`]: struct@crate::markdown::Markdown
//! [`AnsiText!`]: struct@crate::ansi_text::AnsiText
//! [`wrap`]: crate::wrap
//!
//! # Full API
//!
//! See [`zng_wgt_text`] for the full widget API.
