I need to connect to "notify::active" signal for Switch widget to process changing of its state. The guides say I shouldn't use onActivate signal, but "notify:active". But I didn't find a way to do it. Can somebody help with it?

Are you referring to gtk.Switch ?

yes, gtk.Switch
if I connect to activate signal by means addOnActivate nothing works. Documentation says I should use "notify::active" event (it belongs to ObjectG, as I understand?), but I cannot find a way to connect to this signal by means of GtkD.

You can use addOnNotify it currently doesn't allow you to specify the property for witch you want to receive the signal (it probably should).

For now you could do:

Switch sw = new Switch();
sw.addOnNotify(&notify);

void notify(ParamSpec param, ObjectG obj)
{
	if(param.getName() == "active")
	{
		//Do stuff
	}
}

Hi!

I would like to share a small example of this:



module gtkd_switch;
// Compile: ldc -w  main.d  `pkg-config --cflags --libs gtkd-3`

import std.stdio;
import gtk.Builder;
import gtk.Main, gtk.Window, gtk.Switch, gtk.Widget;
import gobject.ObjectG ,gobject.ParamSpec;


void on_swt_change(ParamSpec param, ObjectG obj, Switch *obj_switch){
    bool state = obj_switch.getActive();
    writefln("Changed! %b", state);
}

void main(string[] args) {
    Main.init(args);

    Builder g = new Builder();
    g.addFromFile("vista.glade");

    // Widgets from glade file "vista.glade":
    Window w = cast(Window)g.getObject("window1");
    w.setDefaultSize(320, 80);
    w.setTitle("Gtkd Switch addOnNotify");
    Switch swt = cast(Switch)g.getObject("swt_test");

    // Actions:
    w.addOnHide( delegate void(Widget aux){ Main.quit(); } );
    swt.addOnNotify(delegate void (ParamSpec, ObjectG){on_swt_change(ParamSpec, ObjectG, &swt);}, "active");

    w.showAll();
    Main.run();
}
