Mx Toolkit

Mx is a widget toolkit based on Clutter originally designed for the Moblin/MeeGo netbook experience, but evolved into an independent project. To compile these examples you have to install Mx 1.x.

Expander Demo

using Mx;

int main (string[] args) {
    var init_rc = Clutter.init (ref args);

    if (init_rc != Clutter.InitError.SUCCESS) {
        stderr.printf("Clutter Init Error %i\n", init_rc);
        return init_rc;
    }

    var stage = new Clutter.Stage ();
    stage.set_title ("Expander Demo");
    stage.set_size (640, 480);
    stage.user_resizable = true;

    stage.delete_event.connect (() => {
        stdout.printf("Bye!\n");
        Clutter.main_quit();
        return false;
    });

    var expander = new Mx.Expander ();
    expander.label = "Expander";
    stage.add_actor (expander);
    expander.set_position (10, 10);

    expander.expand_complete.connect (() => {
        stdout.printf ("Expand complete (%s)\n",
                       expander.expanded ? "open" : "closed");
    });

    var scroll = new Mx.ScrollView ();
    expander.add_actor (scroll);
    scroll.set_size (320, 240);

    var grid = new Mx.Grid ();
    scroll.add_actor (grid);

    for (var i = 1; i <= 50; i++) {
        grid.add_actor (new Mx.Button.with_label (@"Button $i"));
    }

    stage.show ();
    Clutter.main ();

    return 0;
}
