我正在使用Rust稳定版1.30和Relm。我想出了如何设置默认窗口大小,但至少在视图内部,我不知道如何设置图标!宏。
这是我的main.rs
extern crate gtk;
extern crate chessground;
#[macro_use]
extern crate relm;
extern crate relm_attributes;
#[macro_use]
extern crate relm_derive;
extern crate shakmaty;
extern crate rsvg;
use gtk::prelude::*;
use gtk::GtkWindowExt;
use relm::Widget;
use relm_attributes::widget;
use shakmaty::{Square, Board};
use chessground::{Ground, UserMove, SetBoard};
use rsvg::{Handle};
use self::Msg::*;
#[derive(Msg)]
pub enum Msg {
Quit,
PieceMoved(Square, Square),
}
#[widget]
impl Widget for Win {
fn model() -> Board {
Board::default()
}
fn update(&mut self, event: Msg) {
match event {
Quit => gtk::main_quit(),
PieceMoved(orig, dest) => {
if let Some(piece) = self.model.remove_piece_at(orig) {
self.model.set_piece_at(dest, piece, false);
self.ground.emit(SetBoard(self.model.clone()));
}
}
}
}
view! {
gtk::Window {
title: "Chessground",
property_default_width: 600,
property_default_height: 600,
#[name="ground"]
Ground {
UserMove(orig, dest, _) => PieceMoved(orig, dest),
},
delete_event(_, _) => (Quit, Inhibit(false)),
}
}
}
fn main() {
let icon = Handle::new_from_str(include_str!("wQ.svg")).expect("Could not find icon !");
// how to set up the given icon ?
Win::run(()).expect("initialized gtk");
}
我的意思是,如何将窗口main中定义的图标设置为其图标? 请注意,该图标已使用rsvg crate实例化。
答案 0 :(得分:1)
最后我管理了:
哪个给我:
extern crate gtk;
extern crate chessground;
#[macro_use]
extern crate relm;
extern crate relm_attributes;
#[macro_use]
extern crate relm_derive;
extern crate shakmaty;

use gtk::prelude::*;
use gtk::GtkWindowExt;
use relm::Widget;
use relm_attributes::widget;
use shakmaty::{Square, Board};
use chessground::{Ground, UserMove, SetBoard};
use rsvg::{Handle};
use rsvg::HandleExt;
use self::Msg::*;
#[derive(Msg)]
pub enum Msg {

}
#[widget]

}

self.ground.emit(SetBoard(self.model.clone()));
}
}
}
}
view! {

property_default_height: 600,
// HERE
icon: &Handle::new_from_str(include_str!("wQ.svg"))
.expect("Could not find icon !")
.get_pixbuf()
.expect("No pixbuf for the icon !"),
#[name="ground"]
Ground {

},
delete_event(_, _) => (Quit, Inhibit(false)),

}
}
