}Expand description
Trait containing manually implemented methods of Dialog.
Required Methods
fn response_for_widget<P: IsA<Widget>>(&self, widget: &P) -> ResponseType
sourcefn run_future<'a>(&'a self) -> Pin<Box<dyn Future<Output = ResponseType> + 'a>>
 
fn run_future<'a>(&'a self) -> Pin<Box<dyn Future<Output = ResponseType> + 'a>>
Shows the dialog and returns a Future that resolves to the
ResponseType on response.
use gtk4::prelude::*;
let dialog = gtk4::MessageDialog::builder()
   .buttons(gtk4::ButtonsType::OkCancel)
   .text("What is your answer?")
   .build();
let answer = dialog.run_future().await;
dialog.close();
println!("Answer: {:?}", answer);sourcefn run_async<F: FnOnce(&Self, ResponseType) + 'static>(&self, f: F)
 
fn run_async<F: FnOnce(&Self, ResponseType) + 'static>(&self, f: F)
Shows the dialog and calls the callback when a response has been received.
Important: this function isn’t blocking.
use gtk4::prelude::*;
let dialog = gtk4::MessageDialog::builder()
   .buttons(gtk4::ButtonsType::OkCancel)
   .text("What is your answer?")
   .build();
dialog.run_async(|obj, answer| {
    obj.close();
    println!("Answer: {:?}", answer);
});
