Constructor & Destructor Documentation

SolarSystemSingleComponent::SolarSystemSingleComponent ( SolarSystemComposite *  parent,
KSPlanetBase *  kspb,
bool(*)()  visibleMethod 
)

Initialize visible method, minimum size and sizeScale.

Definition at line 33 of file solarsystemsinglecomponent.cpp.

SolarSystemSingleComponent::~SolarSystemSingleComponent (  )  [virtual]

Definition at line 46 of file solarsystemsinglecomponent.cpp.


Member Function Documentation

void SolarSystemSingleComponent::draw ( QPainter &  psky  )  [virtual]

Draw the object on the SkyMap psky Reference to the QPainter on which to paint.

Implements SkyComponent.

Definition at line 90 of file solarsystemsinglecomponent.cpp.

void SolarSystemSingleComponent::drawTrails ( QPainter &   )  [protected, virtual]

Draw trails for objects.

Reimplemented from SkyComponent.

Definition at line 166 of file solarsystemsinglecomponent.cpp.

SkyObject * SolarSystemSingleComponent::findByName ( const QString &  name  )  [virtual]

Search the children of this SkyComponent for a SkyObject whose name matches the argument name the name to be matched.

Returns:
a pointer to the SkyObject whose name matches the argument, or a NULL pointer if no match was found.
Note:
This function simply returns the NULL pointer; it is reimplemented in various sub-classes

Reimplemented from SkyComponent.

Definition at line 56 of file solarsystemsinglecomponent.cpp.

SkyObject * SolarSystemSingleComponent::objectNearest ( SkyPoint *  p,
double &  maxrad 
) [virtual]

Find the SkyObject nearest the given SkyPoint.

Look for a SkyObject that is nearer to point p than maxrad. If one is found, then maxrad is reset to the separation of the new nearest object. p pointer to the SkyPoint to search around maxrad reference to current search radius

Returns:
a pointer to the nearest SkyObject
Note:
This function simply returns a NULL pointer; it is reimplemented in various sub-classes.

Reimplemented from SkyComponent.

Definition at line 65 of file solarsystemsinglecomponent.cpp.

KSPlanetBase* SolarSystemSingleComponent::planet (  )  [inline]

Return pointer to stored planet object.

Definition at line 49 of file solarsystemsinglecomponent.h.

bool SolarSystemSingleComponent::selected (  )  [virtual]
Returns:
true if component is to be drawn on the map.

Reimplemented from SkyComponent.

Definition at line 52 of file solarsystemsinglecomponent.cpp.

void SolarSystemSingleComponent::update ( KSNumbers *   )  [virtual]

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

See also:
SingleComponent::update()
ListComponent::update()
ConstellationBoundaryComponent::update()

Reimplemented from SkyComponent.

Definition at line 74 of file solarsystemsinglecomponent.cpp.

void SolarSystemSingleComponent::updatePlanets ( KSNumbers *  num  )  [virtual]

Reimplemented from SkyComponent.

Definition at line 80 of file solarsystemsinglecomponent.cpp.
