Member Function Documentation

formatOutput()

QString FormatDateTime::formatOutput	(	CoordUnitsDate	coordUnitsDate,
		CoordUnitsTime	coordUnitsTime,
		double	value
	)		const

Format the date/time value according to date/time format settings.

Definition at line 127 of file FormatDateTime.cpp.

{
  LOG4CPP_INFO_S ((*mainCat)) << "FormatDateTime::formatOutput"
                              << " value=" << value;

  ENGAUGE_ASSERT (m_formatsDateFormat.contains (coordUnitsDate));
  ENGAUGE_ASSERT (m_formatsTimeFormat.contains (coordUnitsTime));

  QString format = m_formatsDateFormat [coordUnitsDate] + " " + m_formatsTimeFormat [coordUnitsTime];
  format = format.trimmed();

  // Range of unsigned versus signed is not a problem here. A signed value maxes out at 2.4 billion
  // which is year 2038
  QDateTime dt = QDateTime::fromTime_t (unsigned (qFloor (value)));

  return dt.toTimeSpec(REFERENCE_TIME_ZONE).toString (format);
}

parseInput()

QValidator::State FormatDateTime::parseInput	(	CoordUnitsDate	coordUnitsDate,
		CoordUnitsTime	coordUnitsTime,
		const QString &	stringUntrimmed,
		double &	value
	)		const

Parse the input string into a time value.

Success flag is false if parsing failed. Leading/trailing spaces are trimmed (=ignored)
