[Gtk-sharp-list] Switching focus on objects as pressing "tab" key ?

[Jesper K. Pedersen]

In connection with working on a small application where I need to
automate entry of data with a barcode reader I need to be able to
switch between gtk.entry objects on performing they keycode
"return" (activate) event.

I had hoped there were either a way to "inject" a keycode in the gtk
key event system or a simple way to switch to the next gtk.entry object.

Any ideas?

Thank's
