//! # GTK+ 3 bindings
//!
//! This library contains safe Rust bindings for [GTK+ 3](http://www.gtk.org), a
//! multi-platform GUI toolkit. It's a part of [Gtk-rs](http://gtk-rs.org/).
//!
//! The library is a work in progress: expect missing bindings and breaking
//! changes. A steadily increasing share of the code is machine-generated from
//! `GObject` introspection metadata. The API docs were converted from the
//! upstream ones so until they've all been reviewed there will be incongruities
//! with actual Rust APIs.
//!
//! See also:
//!
//! - [Gtk-rs documentation overview](http://gtk-rs.org/docs/)
//!
//! - [General `GLib` family types and object system overview](../glib/index.html)

//! # Hello World
//!
//! ```no_run
//! extern crate gtk;
//! use gtk::prelude::*;
//! use gtk::{ButtonsType, DialogFlags, MessageType, MessageDialog, Window};
//!
//! fn main() {
//!     if gtk::init().is_err() {
//!         println!("Failed to initialize GTK.");
//!         return;
//!     }
//!     MessageDialog::new(None::<&Window>,
//!                        DialogFlags::empty(),
//!                        MessageType::Info,
//!                        ButtonsType::Ok,
//!                        "Hello World").run();
//! }
//! ```
//!
//! # Initialization
//!
//! GTK+ needs to be initialized before use by calling [`init`](fn.init.html) or
//! [`Application::new`](struct.Application.html#method.new). You only need to
//! do it once and there is no 'finalize'.
//!
//! # The main loop
//!
//! In a typical GTK+ application you set up the UI, assign signal handlers
//! and run the main event loop:
//!
//! ```no_run
//! extern crate gtk;
//! extern crate gio;
//!
//! // To import all needed traits.
//! use gtk::prelude::*;
//! use gio::prelude::*;
//!
//! use std::env;
//!
//! fn main() {
//!     let uiapp = gtk::Application::new(Some("org.gtkrsnotes.demo"),
//!                                       gio::ApplicationFlags::FLAGS_NONE)
//!                                  .expect("Application::new failed");
//!     uiapp.connect_activate(|app| {
//!         // We create the main window.
//!         let win = gtk::ApplicationWindow::new(app);
//!
//!         // Then we set its size and a title.
//!         win.set_default_size(320, 200);
//!         win.set_title("Basic example");
//!
//!         // Don't forget to make all widgets visible.
//!         win.show_all();
//!     });
//!     uiapp.run(&env::args().collect::<Vec<_>>());
//! }
//! ```
//!
//! # Threads
//!
//! GTK+ is not thread-safe. Accordingly, none of this crate's structs implement
//! `Send` or `Sync`.
//!
//! The thread where `init` was called is considered the main thread. OS X has
//! its own notion of the main thread and `init` must be called on that thread.
//! After successful initialization, calling any `gtk` or `gdk` functions
//! (including `init`) from other threads will `panic`.
//!
//! Any thread can schedule a closure to be run by the main loop on the main
//! thread via [`glib::idle_add`](../glib/source/fn.idle_add.html) or
//! [`glib::timeout_add`](../glib/source/fn.timeout_add.html). This crate has
//! versions of those functions without the `Send` bound, which may only be
//! called from the main thread: [`idle_add`](fn.idle_add.html),
//! [`timeout_add`](fn.timeout_add.html).
//!
//! # Panics
//!
//! This and the `gdk` crate have some run-time safety and contract checks:
//!
//! - Any constructor or free function will panic if called before `init` or on
//! a non-main thread.
//!
//! - Any `&str` or `&Path` parameter with an interior null (`\0`) character will
//! cause a panic.
//!
//! - Some functions will panic if supplied out-of-range integer parameters. All
//! such cases will be documented individually but they're not yet.
//!
//! **A panic in a closure will abort the process.**
//!
//! # Crate features
//!
//! ## Library versions
//!
//! By default this crate provides only GTK+ 3.14 APIs. You can access more
//! modern APIs by selecting one of the following features: `v3_14`, `v3_16`, etc.
//!
//! `Cargo.toml` example:
//!
//! ```toml
//! [dependencies.gtk]
//! version = "0.x.y"
//! features = ["v3_16"]
//! ```
//!
//! **Take care when choosing the version to target: some of your users might
//! not have easy access to the latest ones.** The higher the version, the fewer
//! users will have it installed.
//!
//! ## Lgpl-docs
//!
//! The Gtk-rs crates come with API docs missing because of licensing
//! incompatibilty. You can embed those docs locally via the `embed-lgpl-docs`
//! feature, e.g.
//!
//! ```shell
//! > cargo doc --features embed-lgpl-docs
//! ```
//!
//! Its counterpart `purge-lgpl-docs` removes those docs regardless of edits.
//!
//! These features **rewrite the crate sources** so it's sufficient to enable
//! them once. **Omitting them in the following cargo invocations will not undo
//! their effects!**
