Sometimes, we want to execute two or more Commands at the same time.
In this case, we can use Command::batch function.
use iced::{
widget::{button, column, text_input},
Element, Task,
};
const MY_TEXT_ID: &str = "my_text";
fn main() -> iced::Result {
iced::application(
"batch_commands",
MyApp::update,
MyApp::view,
)
.run()
}
struct MyApp {
some_text: String,
}
impl Default for MyApp {
fn default() -> Self {
MyApp::new().0
}
}
#[derive(Debug, Clone)]
enum Message {
UpdateText(String),
SelectAll,
}
impl MyApp {
fn new() -> (Self, Task<Message>) {
(
Self {
some_text: String::new(),
},
Task::none(),
)
}
fn update(&mut self, message: Message) -> Task<Message> {
match message {
Message::UpdateText(s) => self.some_text = s,
Message::SelectAll => {
return Task::batch(vec![
// Produces a Task that focuses the TextInput with the given Id.
text_input::focus(text_input::Id::new(MY_TEXT_ID)),
// Produces a Task that selects all the content of the TextInput with the given Id.
text_input::select_all(text_input::Id::new(MY_TEXT_ID)),
]);
}
}
Task::none()
}
fn view(&self) -> Element<Message> {
column![
text_input("", &self.some_text)
// Sets the Id of the TextInput.
.id(text_input::Id::new(MY_TEXT_ID))
.on_input(Message::UpdateText),
button("Select all").on_press(Message::SelectAll),
]
.into()
}
}
