我正在尝试增加一个Rust和GTK-RS应用程序的结构,但是我无法弄清如何处理事件连接。我发现问题在于错误的生命周期,但我并不真正理解它如何被修复。
#[derive(Debug)]
struct CreatingProfileUI {
window: gtk::MessageDialog,
profile_name_entry: gtk::Entry,
add_btn: gtk::Button,
cancel_btn: gtk::Button,
}
#[derive(Debug)]
struct UI {
window: gtk::Window,
// Header
url_entry: gtk::Entry,
open_btn: gtk::Button,
// Body
add_profile_btn: gtk::Button,
remove_profile_btn: gtk::Button,
profiles_textview: gtk::TextView,
// Creating profile
creating_profile: CreatingProfileUI,
// Statusbar
statusbar: gtk::Statusbar,
}
impl UI {
fn init(&self) {
self.add_profile_btn
.connect_clicked(move |_| { &self.creating_profile.window.run(); });
}
}
我遇到了以下错误:
error[E0477]: the type `[closure@src/main.rs:109:46: 111:6 self:&UI]` does not fulfill the required lifetime
--> src/main.rs:109:30
|
109 | self.add_profile_btn.connect_clicked(move |_| {
| ^^^^^^^^^^^^^^^
|
= note: type must satisfy the static lifetime
ButtonExt::connect_clicked
要求一个具有'static
