GTK is an object-oriented framework. It is written in C, which does not support object-orientation out of the box. That is why, GTK relies on the GObject library to provide the object system.
We already learned, that
gtk-rs maps GObject concepts like inheritance and interfaces to Rust traits.
In this chapter we will additionally find out:
- How to manage the memory of GObjects.
- How to create our own GObjects via subclassing.
- How to deal with generic values.
- How to use properties.
- How to emit and receive signals.
