Yes, Gtk is built using GLib and so depends on it. Here's some example
code I'm using in a Vala project (sorry) that uses GLib.Timeout:
public class TimeoutEntry : Granite.Entry, Gtk.Buildable {
private static const uint DEFAULT_TIMEOUT = 300; // in ms
/**
* The timeout length in milliseconds before {@see #timed_out} signal
* is called. The value defaults to 300.
*/
public uint timeout { get; set; default = DEFAULT_TIMEOUT; }
/**
* A callback fired after {@see timeout} length of time has expired in the
* non-empty entry field.
*/
public signal void timed_out();
private bool timeout_changed = false;
construct {
// add signals and callbacks
notify["timeout"].connect(() => { timeout_changed = false; });
realize.connect(() => { GLib.Timeout.add(timeout, emit_timed_out); });
changed.connect(() => { timeout_changed = true; }); // reset timeout
}
private bool emit_timed_out() {
if (timeout_changed) {
GLib.Timeout.add(timeout, emit_timed_out);
return (timeout_changed = false);
}
if (text != "") { timed_out(); }
return !timeout_changed;
}
}
Here I'm calling the timed_out signal which will execute an associated
callback. I'm not sure what you mean by "trigger a gtk event on a
timer", if I understand it correctly this should be helpful
gobject.Signals.emitv <http://gtkd.mikewey.eu/src/gobject/Signals.html>
and have a look here:

Hope this helps,

PS: the problems you're encountering seem less and less like problems
with D (unless they're compiler bugs)... and more like issues with
Gtk/GLib. The GTK IRC channel can be very (very) quiet but it might help.

It turned out there was a Timer in glib and glib is a part of gtk(I
think). When you use gtkd you have acces to glib and that worked but
it takes 50 procent of my cpu. (this was actually pretty strange. It
worked fast and good untill I rebooted. Now it runs prety slow)
and I don't think you can trigger a gtk event on a timer.

Is there a timer function built into gtk? Or can you have a
separate thread trigger a gtk event on a timer?

is that when using gtk I have to call Main.run(); and it pauses
then untill the windows are all closed. when I place a loop before
Main.run() I never get a window so If I want to use some kind of
timer using threads I need to use shared? (correct me if I'm wrong)
