rgtk

Rust bindings and wrappers for GLib, GDK 3, GTK+ 3 and Cairo.

Installation

rgtk expects GTK+, GLib and Cairo development files to be installed on your system. Optionally, it is recommended to install the debug packages containing helpful debug symbols.

For Debian based system:

> apt-get install libgtk-3-dev   libglib2.0-dev   libcairo2-dev
> apt-get install libgtk-3-0-dbg libglib2.0-0-dbg libcairo2-dbg

For Fedora:

> yum install gtk3-devel glib2-devel

For OSX, install XQuartz, then:

> brew install gtk+3 --without-x11
> export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig

rgtk targets GTK+ 3.6 by default, verions 3.4 to 3.14 support is enabled by requesting a corresponding feature e.g.

> cargo build --features GTK_3_10

We are currently targetting rust master compiler to build rgtk, make sure you have the latest version before submitting any bugs.

In examples you can find some tests showing off the functionality, these can be built and run as follows:

> cd examples/gtktest
> cargo run

> cd examples/cairotest
> cargo run

rgtk should build and work on both OSX and GNU/Linux. We plan on adding windows support in the future.

When building documentation don't forget to specify the feature set you're using:

> cargo doc --feature GTK_3_12

Your local copy can be accessed using your browser at

file:///{rgtk_location}/target/doc/rgtk/index.html

You can also access a daily build of the docs via the internet:

Including rgtk as a cargo dependency

To include rgtk as a cargo dependency you have to add it to your Cargo.toml and specify the GTK version you want using Cargo features

[dependencies.rgtk]
git = "https://github.com/jeremyletang/rgtk.git"
features = ["GTK_3_12"]

Currently available GTK versions are 3.14, 3.12, 3.10, 3.8, 3.6 and 3.4

Use rgtk

To implement GTK+ inheritance in rust, we implemented gtk superclasses as traits located in rgtk::gtk::traits::*. The various widgets implement these traits and live in rgtk::gtk::*.

For your convenience the various traits are reexported in the rgtk::* namespace as Gtk{trait_name}Trait so you can just use...

extern mod rgtk;
use rgtk::*;

...to easily access all the gtk widgets and all traits methods:

let button = gtk::Button:new(); // You have access to the struct methods of gtk::Button aswell
                                // as the trait methods from gtk::traits::Button as GtkButtonTrait.

You probably know but Gtk+ uses its own GObject system: inherited class and interface.

To respect this design, I follow a special design on rgtk:

• Interface -> Implement them on a trait with only default methods.
• Class -> Implement the construct on the class impl and other methods on a traits.
• Sub-class -> Implement all the methods on the class.

Example for GtkOrientable, GtkBox, GtkButtonBox:

GtkOrientable is an interface with all methods implemented as default method of the trait gtk::traits::Orientable.

GtkBox is a class with constructors implemented on the struct gtk::Box, and the other method as default methods of the trait gtk::traits::Box. So gtk::Box implements gtk::traits::Orientable and gtk::traits::Box.

GtkButtonBox is a sub-class of GtkBox, the struct gtk::ButtonBox implements all the methods of GtkButtonBox and the traits gtk::traits::Orientable and gtk::traits::Box.

Finally, all the gtk widgets implement the trait gtk::traits::Widget.
