将GtkSourceView与Rust一起使用

Question

我想在我的Rust应用程序中使用GtkSourceView。

我已经使用Glade创建了UI文件。我必须安装组件并链接它。

这是我的Rust代码：

use gtk::prelude::*;


fn main() {
    if gtk::init().is_err() {
        println!("Failed to initialize GTK.");
        return;
    }
    let glade_src = include_str!("user_interface.glade");
    let builder = gtk::Builder::new_from_string(glade_src);    
    let window: gtk::Window = builder.get_object("main_window").unwrap();

    window.show_all();

    gtk::main();
}

当我尝试cargo run时，...and我得到的错误

alex@smartalex-bed:~/.repos/codelib/rust/venom$ cargo run
    Finished dev [unoptimized + debuginfo] target(s) in 0.05s
     Running `target/debug/venom`

(venom:10028): Gtk-ERROR **: 04:25:30.689: failed to add UI: .:17:1 Invalid object type 'GtkSourceView'
Trace/breakpoint trap (core dumped)

我找到了this并尝试将其包含在我的Cargo.toml中，但是错误仍然存在。

如何在我的Rust应用程序中使用GtkSourceView？

这是user_interface.glade

我可以通过添加以下代码行来运行该程序：

sourceview::View::static_type();

完整的示例代码如下：

use gtk::prelude::*;

fn main() {
    if gtk::init().is_err() {
        println!("Failed to initialize GTK.");
        return;
    }

    sourceview::View::static_type();

    let glade_src = include_str!("user_interface.glade");
    let builder = gtk::Builder::new_from_string(glade_src);
    let window: gtk::Window = builder.get_object("main_window").unwrap();

    window.show_all();

    gtk::main();
}

此外，Cargo.toml还包含以下依赖关系：

[dependencies]
gtk = { version = "*", features = ["v3_22"] }
sourceview = "*"
