pub struct BuilderRustScope { /* private fields */ }
Expand description
An implementation of BuilderScope
that can bind Rust callbacks.
use gtk::prelude::*;
use gtk::subclass::prelude::*;
let builder = gtk::Builder::new();
let scope = gtk::BuilderRustScope::new();
scope.add_callback("print_label", |values| {
let button = values[1].get::<gtk::Button>().unwrap();
println!("{}", button.label().unwrap().as_str());
None
});
builder.set_scope(Some(&scope));
// can also be used with template_callbacks
pub struct Callbacks {}
#[gtk::template_callbacks]
impl Callbacks {
#[template_callback]
fn button_clicked(button: >k::Button) {
button.set_label("Clicked");
}
}
Callbacks::add_callbacks_to_scope(&scope);
GLib type: GObject with reference counted clone semantics.
Implementations§
source§impl BuilderRustScope
impl BuilderRustScope
pub fn new() -> Self
sourcepub fn add_callback<N: Into<String>, F: Fn(&[Value]) -> Option<Value> + 'static>(
&self,
name: N,
callback: F,
)
pub fn add_callback<N: Into<String>, F: Fn(&[Value]) -> Option<Value> + 'static>( &self, name: N, callback: F, )
Adds a Rust callback to the scope with the given name
. The callback
can then be accessed from a Builder
by referring
to it in the builder XML, or by using
Builder::create_closure
.
