Note that reverting to v1.7 will invalidate any saved working frequencies from v1.8 but proceeding to v1.8 again will present a reset set of working frequencies i.e. any user defined entries in v1.8 will be lost of a v1.8 -> v1.7 -> v1.8 transition is made. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@8018 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

// Encapsulates a collection of frequencies with associated modes.
|
|
// The implementation is a table containing the list of IARU region,
|
|
// Frequency and mode tuples which are editable. A third column is
|
|
// modeled in the model which is an immutable double representation
|
|
// of the corresponding Frequency item scaled to mega-Hertz.
|
|
//
|
|
// The list is ordered. A filter on IARU region and mode is
|
|
// available and is set by the filter(Region, Mode) method. The
|
|
// Region value IARURegions::ALL and the Mode value Modes::ALL may be
|
|
// optionally given which passes all rows in the filtered column.
|
|
//
|
|
// Responsibilities
|
|
//
|
|
// Stores internally a list of unique region, frequency mode tuples.
|
|
// Provides methods to add and delete list elements. Provides range
|
|
// iterators for a filtered view of the underlying table.
|
|
//
|
|
// Collaborations
|
|
//
|
|
// Implements the QSortFilterProxyModel interface for a list of spot

// frequencies.
