Constructor & Destructor Documentation

HorizonComponent::HorizonComponent ( SkyComposite *  parent )

explicit

Constructor parent Pointer to the parent SkyComposite object.

Definition at line 36 of file horizoncomponent.cpp.

HorizonComponent::~HorizonComponent ( )

virtual

Destructor.

Member Function Documentation

void HorizonComponent::draw ( SkyPainter *  skyp )

virtual

Draw the Horizon on the Sky map map Pointer to the SkyMap object psky Reference to the QPainter on which to paint.

Implements SkyComponent.

Definition at line 75 of file horizoncomponent.cpp.

bool HorizonComponent::selected ( )

virtual

Returns

true if component is to be drawn on the map.

Reimplemented from SkyComponent.

Definition at line 56 of file horizoncomponent.cpp.

void HorizonComponent::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. However, the precession and nutation must also be recomputed periodically. Requests to do so are sent through the doPrecess parameter. 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 PointListComponent.
