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.
◆ findByName()
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.
- Returns
- a pointer to the SkyObject whose name matches the argument, or a nullptr pointer if no match was found.
- Note
- 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.
◆ objectNearest()
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
- Returns
- a pointer to the nearest SkyObject
- Note
- 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 67 of file listcomponent.cpp.
◆ update()
|
overridevirtual |
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
- Note
- 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 SupernovaeComponent, StarComponent, and SolarSystemListComponent.
