 Ops! I wanted going too fast 0:)

 Thank you for your ideas. Only a last question. If I destroy
 Gtk.ComboBox, is respective Gtk.ListStore destroyed?

have you tried having a set_model(Gtk::ListStore) after your super() ?
try 'p model.inspect' or 'p model.methods' before your model.clear, to=20
see, if there's a model assigned.

 If I do that, get:

 	(eval):2:in `set_property': Class isn't supported (TypeError)

 I think there isn't. This is result from inspect:

 	"#<#<Class:0xb681ce58>:0xb6794058 ptr=3D0x85c5790>"

sorry, i thought you should add:<br>
@mymodel=Gtk::ListStore.new(String,String)<br>
super()&nbsp; # for ComboBox.new<br>
set_model(@mymodel)<br>
<br>
and then these should do the same:<br>
@mymodel.clear<br>
model.clear<br>
<br>
it works this way for me in 0.14.1<br>

 Ops! I wanted going too fast 0:)

 Thank you for your ideas. Only a last question. If I destroy
 Gtk.ComboBox, is respective Gtk.ListStore destroyed?

i think so, <br>
if not, connect a signal to combobox's destroy event, and destroy model
too,<br>
verify that by connecting a to treemodel's destroy and print a 'I'm
treemodel, and i'm called to be destroyed :)"<br>
this is the way I'd verify it, at least.<br>

btw, don't you experience strange segfaults in 0.15? since i any time i
upgrade to gentoo's 0.15 ruby-gtk2, i have lots of errors and segfaults
on different checkpoints of my programs, running the same job, so i
decide to downgrade each time. :(<br>
what distro are you running?<br>
