◆ draw()

void HorizonComponent::draw ( SkyPainter skyp)
overridevirtual

Draw the Horizon on the Sky map.

map Pointer to the SkyMap object psky Reference to the QPainter on which to paint

Implements SkyComponent.

◆ selected()

bool HorizonComponent::selected ( )
overridevirtual
Returns
true if component is to be drawn on the map.

Reimplemented from SkyComponent.

◆ update()

void HorizonComponent::update ( KSNumbers )
overridevirtual

Update the sky position(s) of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of its member object(s). However, the precession and nutation must also be recomputed periodically. num Pointer to the KSNumbers object
