Constructor & Destructor Documentation

◆ TrailObject() [1/2]

TrailObject::TrailObject ( int t = TYPE_UNKNOWN,
dms r = dms(0.0),
dms d = dms(0.0),
float m = 0.0,
const QString & n = QString() )
explicit

Constructor.

Definition at line 25 of file trailobject.cpp.

◆ TrailObject() [2/2]

TrailObject::TrailObject ( int t,
double r,
double d,
float m = 0.0,
const QString & n = QString() )

Constructor.

Definition at line 29 of file trailobject.cpp.

◆ ~TrailObject()

TrailObject::~TrailObject ( )
override

Definition at line 33 of file trailobject.cpp.

Member Function Documentation

◆ addToTrail()

void TrailObject::addToTrail ( const QString & label = QString())

adds a point to the planet's trail

Definition at line 60 of file trailobject.cpp.

◆ clearTrail()

void TrailObject::clearTrail ( )

clear the Trail

Definition at line 79 of file trailobject.cpp.

◆ clearTrailsExcept()

void TrailObject::clearTrailsExcept ( SkyObject * o)
static

Remove trail for all objects but one which is passed as parameter.

It has SkyObject type for generality.

Definition at line 86 of file trailobject.cpp.

◆ clipTrail()

void TrailObject::clipTrail ( )

removes the oldest point from the trail

Definition at line 67 of file trailobject.cpp.

◆ clone()

TrailObject * TrailObject::clone ( ) const
overridevirtual

Create copy of object.

This method is virtual copy constructor. It allows for safe copying of objects. In other words, KSPlanet object stored in SkyObject pointer will be copied as KSPlanet.

Each subclass of SkyObject MUST implement clone method. There is no checking to ensure this, though.

Returns
pointer to newly allocated object. Caller takes full responsibility for deallocating it.

Reimplemented from SkyObject.

Definition at line 38 of file trailobject.cpp.

◆ drawTrail()

void TrailObject::drawTrail ( SkyPainter * skyp) const

Definition at line 102 of file trailobject.cpp.

◆ hasTrail()

bool TrailObject::hasTrail ( ) const
inline
Returns
whether the planet has a trail

Definition at line 36 of file trailobject.h.

◆ initPopupMenu()

void TrailObject::initPopupMenu ( KSPopupMenu * pmenu)
overridevirtual

Initialize the popup menut.

This function should call correct initialization function in KSPopupMenu. By overloading the function, we don't have to check the object type when we need the menu.

Reimplemented from SkyObject.

Definition at line 51 of file trailobject.cpp.

◆ trail()

const QList< SkyPoint > & TrailObject::trail ( ) const
inline
Returns
a reference to the planet's trail

Definition at line 42 of file trailobject.h.

◆ updateTrail()

void TrailObject::updateTrail ( dms * LST,
const dms * lat )

update Horizontal coords of the trail

Definition at line 45 of file trailobject.cpp.

◆ m_TrailLabels

protected

Definition at line 72 of file trailobject.h.

◆ MaxTrail

const int TrailObject::MaxTrail = 400
static

Maximum trail size.

Definition at line 66 of file trailobject.h.

◆ Trail

QList<SkyPoint> TrailObject::Trail
protected

Definition at line 71 of file trailobject.h.

◆ trailObjects

QSet< TrailObject * > TrailObject::trailObjects
