Detailed Description

Represents the deep sky objects separated by catalogs.

Custom Catalogs are a standalone component.

Note

this Component is similar to ListComponent, but the deep sky objects are stored in four separate QLists.

void DeepSkyComponent::clear

Definition at line 640 of file deepskycomponent.cpp.

void DeepSkyComponent::draw ( SkyPainter *  skyp )

virtual

Draw the object on the SkyMap skyp a pointer to the SkyPainter to use.

Implements SkyComponent.

Definition at line 363 of file deepskycomponent.cpp.

void DeepSkyComponent::drawLabels

(

)

Definition at line 473 of file deepskycomponent.cpp.

SkyObject * DeepSkyComponent::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.

Reimplemented from SkyComponent.

Definition at line 495 of file deepskycomponent.cpp.

const QList<DeepSkyObject*>& DeepSkyComponent::objectList ( ) const

inline

Definition at line 106 of file deepskycomponent.h.

SkyObject * DeepSkyComponent::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 521 of file deepskycomponent.cpp.

void DeepSkyComponent::objectsInArea ( QList< SkyObject * > &  list, const SkyRegion &  region  )

virtual

Searches the region(s) and appends the SkyObjects found to the list of sky objects.

Look for a SkyObject that is in one of the regions If found, then append to the list of sky objects list list of SkyObject to which matching list has to be appended to region defines the regions in which the search for SkyObject should be done within

Returns

void

Reimplemented from SkyComponent.

Definition at line 500 of file deepskycomponent.cpp.

bool DeepSkyComponent::selected ( )

virtual

Returns

true if component is to be drawn on the map.

Reimplemented from SkyComponent.

Definition at line 54 of file deepskycomponent.cpp.

void DeepSkyComponent::update ( KSNumbers *  num = 0 )

virtual

Update the sky positions of this component.

FIXME -jbb does nothing now

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 SkyComponent.
