-/*!
-
- \brief GConfItem is a simple C++ wrapper for GConf.
-
- Creating a GConfItem instance gives you access to a single GConf
- key. You can get and set its value, and connect to its
- valueChanged() signal to be notified about changes.
-
- The value of a GConf key is returned to you as a QVariant, and you
- pass in a QVariant when setting the value. GConfItem converts
- between a QVariant and GConf values as needed, and according to the
- following rules:
-
- - A QVariant of type QVariant::Invalid denotes an unset GConf key.
-
- - QVariant::Int, QVariant::Double, QVariant::Bool are converted to
- and from the obvious equivalents.
-
- - QVariant::String is converted to/from a GConf string and always
- uses the UTF-8 encoding. No other encoding is supported.
-
- - QVariant::StringList is converted to a list of UTF-8 strings.
-
- - QVariant::List (which denotes a QList<QVariant>) is converted
- to/from a GConf list. All elements of such a list must have the
- same type, and that type must be one of QVariant::Int,
- QVariant::Double, QVariant::Bool, or QVariant::String. (A list of
- strings is returned as a QVariant::StringList, however, when you
- get it back.)
-
- - Any other QVariant or GConf value is essentially ignored.
-
- \warning GConfItem is as thread-safe as GConf.
