Function
GioSettingsGetMapping
Declaration
gboolean
(* GSettingsGetMapping) (
GVariant* value,
gpointer* result,
gpointer user_data
)
Description [src]
The type of the function that is used to convert from a value stored
in a GSettings to a value that is useful to the application.
If the value is successfully mapped, the result should be stored at
result and TRUE returned. If mapping fails (for example, if value
is not in the right format) then FALSE should be returned.
If value is NULL then it means that the mapping function is being
given a “last chance” to successfully return a valid value. TRUE
must be returned in this case.
