Detailed Description

A spin box for displaying/entering angular values.

This class can accept angles in various formats commonly used in astronomy including decimal degrees, DMS and HMS.


Member Enumeration Documentation

Used to decide how to display the angle.

Enumerator:
DMSLetters  Degrees, minutes and seconds, e.g. 180d 4m 8s.
DMSSymbols  Degrees, minutes and seconds, e.g. 180° 4' 8".
HMSLetters  Hours, minutes and seconds, e.g. 12h 4m 6s.
HMSSymbols  Hours, minutes and seconds, e.g. 12h 4' 6s".
DecimalDeg  Decimal degrees, e.g. 180.06888.

Determines how positive and negative values are indicated.

Enumerator:
Normal  negative values have '-' prefix
NormalPlus  positive values have '+' prefix, negative values have '-' prefix.
Longitude  positive values have 'E' prefix, negative values have 'W' prefix.
Latitude  positive values have 'N' prefix, negative values have 'S' prefix.
