Hello,

First, thanks for answering some of my questions before.  
I was able to send commands to a VTE terminal using:

```
vte_terminal.feed_child("ls\n")

```

Now, to a new question, to Gtk::ComboBox.

Is there a way to open the dropdown box without  
clicking on the arrow?  
Specifically, I would like to open the dropdown box  
whenever the combo\_box is clicked:

combo\_box.signal\_connect(“event”) do |widget, event|  
case event.event\_type  
when Gdk::Event::BUTTON\_PRESS  
# now open the dropdown menu as if the user  
# would have clicked the arrow  
end  
end

However the wiki docu at  
[http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AComboBox](http://ruby-gnome2.sourceforge.jp/hiki.cgi?Gtk%3A%3AComboBox)  
does not seem to hint at doing this.

Regards,  
“shev”

Use Gtk::ComboBox#popup.

I think this is a default behavior.

## Thanks,
