We can implement theme method in Sandbox to return the desired theme.
use iced::{
widget::{column, text},
Element,
};
fn main() -> iced::Result {
iced::application("changing_theme", MyApp::update, MyApp::view)
.theme(MyApp::theme)
.run()
}
struct MyApp {
_state: String,
}
impl Default for MyApp {
fn default() -> Self {
MyApp::new()
}
}
#[derive(Debug, Clone)]
enum Message {
_Message1,
}
impl MyApp {
fn new() -> Self {
Self {
_state: String::new(),
}
}
fn update(&mut self, _message: Message) {
todo!()
}
fn view(&self) -> Element<Message> {
column!(text("Hello World!".to_string()),).into()
}
fn theme(&self) -> iced::Theme {
iced::Theme::Dark
// or
// iced::Theme::Light
}
}
