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. You should set upper and lower limits (maximum, minimum) and decide whether the values wrap around or are blocked at the limits (wrapping).

Member Enumeration Documentation

DisplayFormat

enum AngleSpinBox::DisplayFormat

Used to decide how to display the angle.

Enumerator
DMSLetters	Degrees, minutes and seconds, e.g. 180d 4m 8s, with negative values, [-360..360d].
DMSSymbols	Degrees, minutes and seconds, e.g. 180° 4' 8", with negative values, [-360..360°].
DMSLettersUnsigned	Degrees, minutes and seconds, e.g. 180d 4m 8s, [0..360d].
DMSSymbolsUnsigned	Degrees, minutes and seconds, e.g. 180° 4' 8", [0..360°].
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.

PrefixType

enum AngleSpinBox::PrefixType

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.
