Ok, so here another question...
I want to implement drag and drop in a gtklistbox.
If i add buttons to gtklistbox, set button as drag source, it works.
If i add complex widgets to gtklistbox, as my container (gtkgrid)
doesn't have a window, it fails to be a drag source.
That's why i'm looking for a container with a window (and tried with
GtkLayout)
https://wiki.gnome.org/GnomeLove/DragNDropTutorial
"Note that these GTK+ widgets must have an associated X Window, check
using GTK_WIDGET_NO_WINDOW(widget))."
any idea?
regards

What am i missing?
A GtkLayout is like a GtkViewport which you can place widgets at
specific locations and draw on etc, it has the special property
that it does not require space (typically it's used in a scrolled
window).
The reason you would not see the label would be that the layout
does not have any specific size request and as such does not get
allocated any space, so anything packed inside it would be clipped
away from view.

from gi.repository import Gtk
class mywindow(Gtk.Window):
def __init__(self):
Gtk.Window.__init__(self, title="Hello")
box = Gtk.ListBox()
label = Gtk.Label("Hello")
label2 = Gtk.Label("Hello2")
layout = Gtk.Layout()
layout.put(label, 0, 0)
box.add(layout)
box.add(label2)
self.add(box)
win = mywindow()
win.connect("delete-event", Gtk.main_quit)
win.show_all()
win.resize(300, 300)
Gtk.main()
