gtk:icon-paintable-icon-name (object)

object -- a gtk:icon-paintable object
name -- a string with the themed icon name for the icon, or nil if its not a themed icon

Accessor of the icon-name slot of the gtk:icon-paintable class. The gtk:icon-paintable-icon-name function gets the icon name being used for this icon.

When an icon looked up in the icon theme was not available, the icon theme may use fallback icons - either those specified to the gtk:icon-theme-lookup-icon function or the always-available "image-missing". The icon chosen is returned by this function.

If the icon was created without an icon theme, this function returns nil.
