Let's finish this chapter by adding the ability to open MP3 files and show their metadata in the playlist widget we just created.
First of all, we'll remove this line:
cover.set_from_file("cover.jpg");
This is because the image will be set from the data of the MP3 files we play.
We'll use a new crate, so add this line in the [dependencies]
section of your Cargo.toml
:
gtk-sys = "^0.5.0"
Also, add the following line to your main.rs
:
extern crate gtk_sys;
The *-sys
crates of the gtk-rs
ecosystem are low-level crates, the ones that directly bind to the GTK+ C library. Since they're very low-level and require the use of unsafe code, wrappers have been made; these are crates without the -sys
suffix, such as gtk
and gdk
.
