gobject-subclass Build Status

This crate is deprecated and all functionality from in here was merged into glib-rs with the 0.7 release

Infrastructure for writing GObject subclasses in the Rust programming language, and (in the future) bindings for GObject and GIO classes.

Example usage of this can be found here

  • gst-plugin-rs: GStreamer plugin writing infrastructure
  • gtk-subclass: GTK class bindings
  • Listbox Model Data implementation: This is a good, quick example of how to create a GObject conforming struct in Rust. It shows how to make a GObject data class for using with gio::ListStore which is then passed to gtk::ListBox.bind_model()

This is different to gnome-class as it does not require usage of a C#-like DSL in a heavy procedural macro, but instead works directly with Rust traits. Both are built on top of the user-level GLib/GObject/GTK gtk-rs bindings.

It will likely not support all features gnome-class will support. For example it is not easily possible to create new GObject subclasses and expose them to C with the whole instance/class struct and allow adding new virtual methods. Subclassing and overriding of existing GObject virtual methods from C however is perfectly possible.
