Constructor & Destructor Documentation

CatalogComponent::CatalogComponent	(	SkyComposite *	parent,
		const QString &	fname,
		bool	showerrs,
		int	index
	)

Constructor parent Pointer to the parent SkyComposite object.

virtual

Destructor.

Member Function Documentation

void CatalogComponent::draw ( SkyPainter *  skyp )

virtual

Draw custom catalog objects on the sky map.

psky Reference to the QPainter on which to paint

Implements SkyComponent.

Definition at line 107 of file catalogcomponent.cpp.

QString CatalogComponent::fluxFrequency ( ) const

inline

Returns

the frequency of the flux readings in the catalog, if any

Definition at line 66 of file catalogcomponent.h.

QString CatalogComponent::fluxUnit ( ) const

inline

Returns

the unit of the flux measurements in the catalog, if any

Definition at line 69 of file catalogcomponent.h.

bool CatalogComponent::getVisibility ( )

inline

Returns

true if visibility Option is set for this catalog

Note

this is complicated for custom catalogs, because Option::showCatalog() returns a QList<int>, not a bool. This function extracts the correct visibility value and returns the appropriate bool value

Definition at line 78 of file catalogcomponent.h.

QString CatalogComponent::name ( ) const

inline

Returns

the name of the catalog

Definition at line 63 of file catalogcomponent.h.

void CatalogComponent::update ( KSNumbers *  num )

virtual

Update the sky positions of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of the objects in this component. If the KSNumbers* argument is not NULL, this function also recomputes precession and nutation for the date in KSNumbers. num Pointer to the KSNumbers object

Note

By default, the num parameter is NULL, indicating that Precession/Nutation computation should be skipped; this computation is only occasionally required.

Reimplemented from ListComponent.
