I'm trying to create my first widget for awesome. I've often have troubles
remembering what's in what X11 buffer (PRIMARY, SECONDARY, and CLIPBOARD). Thus
I wrote a little widget that shows me the contents. However, this widget seems
to cause awesome to freeze after a couple of hours of use.
I instantiate it this way:
-- selection box
cselp = widget({ type = "textbox"})
vicious.register(cselp, clip, '<span color="yellow">Pri: </span> $1 ||', 1,
"primary")
Any ideas?
Thanks.
