Trait containing manually implemented methods of NativeDialog.
Required Methods
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 gtk::prelude::*;
let dialog = gtk::FileChooserNative::builder()
.title("Select a File")
.build();
dialog.run_future().await;
println!("Selected file: {:?}", dialog.file());
dialog.destroy();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 gtk::prelude::*;
let dialog = gtk::FileChooserNative::builder()
.title("Select a File")
.build();
dialog.run_async(move |obj, answer| {
obj.destroy();
println!("Selected file: {:?}", obj.file());
});
