Member Function Documentation

◆ appendListObject()

void ListComponent::appendListObject ( SkyObject * object)

Add an object to the Object list.

This method is a handy wrapper, which automatically appends the given SkyObject to m_ObjectList and inserts references with all common names (name, name2, longname) into the m_ObjectHash QHash to enable a faster findbyname.

Definition at line 37 of file listcomponent.cpp.

◆ clear()

void ListComponent::clear ( )

Definition at line 27 of file listcomponent.cpp.

◆ findByName()

SkyObject * ListComponent::findByName ( const QString & name,
bool exact = true )

Search the children of this SkyComponent for a SkyObject whose name matches the argument name the name to be matched exact If true, it will return an exact match, otherwise it can return a partial match.

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

Reimplemented from SkyComponent.

Definition at line 61 of file listcomponent.cpp.

◆ objectList()

const QList< SkyObject * > & ListComponent::objectList ( ) const

Definition at line 49 of file listcomponent.h.

◆ objectNearest()

SkyObject * ListComponent::objectNearest ( SkyPoint * p,
double & maxrad )

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 in degrees

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

Reimplemented from SkyComponent.

Reimplemented in StarComponent, and SupernovaeComponent.

Definition at line 78 of file listcomponent.cpp.

◆ update()

void ListComponent::update ( KSNumbers * num = nullptr)

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 nullptr, this function also recomputes precession and nutation for the date in KSNumbers. num Pointer to the KSNumbers object

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

Reimplemented from SkyComponent.

Reimplemented in SolarSystemListComponent, StarComponent, and SupernovaeComponent.
