Trying to find the sweet spot for completeness, usefulness, safety and, performance from the various custom item models and item delegates. git-svn-id: svn+ssh://svn.code.sf.net/p/wsjt/wsjt/branches/wsjtx@5474 ab8295b8-cf94-4d9e-aec4-7959e3be5d79

// Encapsulates information about a collection of unique operating
|
|
// stations per band. The implementation is a table model with the
|
|
// first column being the unique (within the table rows) band name
|
|
// and, the second the frequency offset for transverter usage and,
|
|
// the third the antenna description. All are editable.
|
|
//
|
|
// Responsibilities
|

//
|
|
// Stores internally an unordered table of bands.
|
|
//
|
|
// If an ordered representaion is required then wrapping with an
|
|
// appropriate proxy model is sufficient
|
|
// e.g. QSortFilterProxyModel. A custom SortRole role is provided for
|
|
// the band name column which returns a numeric value (Bands lower
|
|
// frequency limit) which gives a strict frequency ordering by band.
|

// Collaborations

// Implements the QAbstractTableModel interface for a grid of bands
|
|
// with offset frequencies and antenna descriptions.

// Uses the Bands model to lookup band information.
