Re: TreeView and Selection/Selected in Ruby-Gnome2?

Thanks: Not sure how you got your example working
though. Maybe you can give a piece of your code? :slight_smile:

For me, I tried a bit more, and when i used this signal
instead:

button_release_event

and

puts widget.selection.selected[0]

all seems to be fine now.

One problem less on my list, getting
closer to finish that little MidnightCommander
clone. :wink:

i changed your code a bit.
this can do multiple selection, which you’ll need in a
gtk-mini-midnight-commander :slight_smile:
