This is Sushi, a quick previewer for Nautilus, the GNOME desktop file manager. ------------------------------------------------------------------------------ Sushi is a DBus-activated service. For Sushi to popup, applications will have to call the ShowFile method on the org.gnome.NautilusPreviewer interface. If you want to or debug Sushi without a calling application, you can use gdbus(1) to call the ShowFile method manually on the bus. ======= Methods ======= ShowFile(s: FileUri, i: ParentXid, b: CloseIfShown) Activates Sushi previewing the file at the provided URI. If a XID is specified, the Sushi window is made transient to that window. If the CloseIfShown parameter is TRUE, Sushi will close if it's already running. Close() Explicitly closes Sushi.
