Hi I'm experimenting with notify-send
[ecvej@localhost ~]$ notify-send --help
notify-send [OPTION...] <SUMMARY> [BODY] - create a notification
-?, --help Show help options
-u, --urgency=LEVEL Specifies the urgency level (low, normal, critical).
-t, --expire-time=TIME Specifies the timeout in milliseconds at which to expire the notification.
-i, --icon=ICON[,ICON...] Specifies an icon filename or stock icon to display.
-c, --category=TYPE[,TYPE...] Specifies the notification category.
-h, --hint=TYPE:NAME:VALUE Specifies basic extra data to pass. Valid types are int, double, string and byte.
-v, --version Version of the package.
I've googled and experimented but I can't figure out what -c and -h flags are used for?
Also I'd like to generate buttons that when clicked perform actions. Is this possible with notify-send? I think the yum-updatesd does something similar, how does that work?
ps I've seen notify-more but as yum-updatesd gets away with doing it with whats on my system I don't want to install something that isn't needed.
