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).

Definition at line 34 of file AngleSpinBox.hpp.

Member Enumeration Documentation

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.

Definition at line 41 of file AngleSpinBox.hpp.

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.
