OpenIconic
OpenIconic is an very nice open source icon set. Those icons have been integrated into the link::creole[creole parser], so you can use them out-of-the-box.
You can use the following syntax: <&ICON_NAME>
.
@startuml
title: <&heart>Use of OpenIconic<&heart>
class Wifi
note left
Click on <&wifi>
end note
@enduml
It also works with link::salt[salt, the graphical interface designer].
@startsalt
{
Login<&person> | "MyName "
Password<&key> | "**** "
[Cancel <&circle-x>] | [OK <&account-login>]
}
@endsalt
The complete list is available on OpenIconic Website, or you can use the following special diagram:
