Hi,

I’m on porting the ComboBox sample from C to ruby.

There is Gtk::ComboBoxText in use. This class has an remove-methode  
itself and a remove-methode inherited from Gtk::Container. The one from  
Gtk::Container, which will remove the child and not the text from the  
Combo can’t be used?!

Cheers, detlef

It seems that the sample is too tricky for Ruby-GNOME2…  
I think that we don’t need to port the sample.

If you want to port the sample, the following code will work:

text.signal\_emit(“remove”, text.child)  
text.signal\_emit(“add”, entry)

## Thanks,
