为什么 GTK+ 3 会抛出这个错误?

(.:11977): Gtk-ERROR **: 21:10:01.149: failed to add UI: Errore alla riga 1 carattere 1: Il documento deve iniziare con un elemento (es. <book>)

从意大利语翻译成英语:

(.:11977): Gtk-ERROR **: 21:10:01.149: failed to add UI: Error on line 1 char 1: Document must begin with an element (e.g. <book>)

错误表明 Rust 正在尝试打开一个空文件(由 Glade 制作)或者它的语法错误。

我的 Rust 文件编译没有任何错误:

extern crate gtk;

use gtk::traits::*;
use gtk::Builder;
use gtk::Inhibit;

fn main() {
// Initialise gtk components
if gtk::init().is_err() {
println!("Unable to load GTK.");
return;
}

// Load glade file
let builder = Builder::new_from_string("mainWindow.glade");

// Create Window
let window: gtk::Window = builder.get_object("mainWindow").unwrap();

// Set close event
window.connect_delete_event(|_, _| {
gtk::main_quit();
Inhibit(true)
});

// Show the window and call the main() loop of gtk
window.show_all();
gtk::main();
}

( Rust file )

Glade 文件是:

我试图搜索这个错误,但似乎除了我之外没有人遇到过这个尴尬的错误。也许它与我的操作系统有关?我正在使用 Pop!_OS,一个基于 Ubuntu 的 Linux 发行版,由 System76 制作。

最佳答案

gtk::Builder::new_from_string() 函数需要一个包含完整 XML 内容的字符串,而不是文件名。您正在传递 "mainWindow.glade",这是无效的 XML 语法,因此您会收到错误消息(在第 1 行,因为您只写了一行)。

你想要的是调用:

Builder::new_from_file("mainWindow.glade")

PS:Rust 编译器的一个很好的特性是您可以将文件作为文字字符串包含在内,因此您可以编写:

Builder::new_from_string(include_str!("mainWindow.glade"))

然后您将文件的内容编译到程序中。
