Ένα γραφικό στοιχείο κουμπιού συνδεμένο με μια γραμμή προόδου.
public class MyWindow : Gtk.ApplicationWindow {
Gtk.Widget progress_bar;
internal MyWindow (MyApplication app) {
Object (application: app, title: "Grid Example");
var grid = new Gtk.Grid();
progress_bar = new Gtk.ProgressBar ();
progress_bar.show ();
var button = new Gtk.Button.with_label ("Button");
button.clicked.connect (on_button_click);
button.show ();
this.add(grid);
grid.attach(button, 0, 1, 1, 1);
grid.attach_next_to (progress_bar, button, Gtk.PositionType.BOTTOM, 1, 1);
grid.show ();
}
void on_button_click (Gtk.Button button) {
(progress_bar as Gtk.ProgressBar).pulse ();
}
}
public class MyApplication : Gtk.Application {
protected override void activate () {
new MyWindow (this).show ();
}
internal MyApplication () {
Object (application_id: "org.example.MyApplication");

public int main (string[] args) {
