Detailed Description

Public slots in this class may be used in Stellarium scripts, and are accessed as member function to the "core" scripting object. Module-specific functions, such as setting and clearing of display flags (e.g. LandscapeMgr::setFlagAtmosphere) can be accessed directly via the scripting object with the class name, e.g. by using the scripting command: LandscapeMgr.setFlagAtmosphere(true);

Member Function Documentation

static void StelMainScriptAPI::addToSelectedObjectInfoString	(	const QString &	str,
		bool	replace = `false`
	)

staticslot

if

replace==true, replace this extra string, if false, add to it. Note that while most objects keep this information after unselection and reselection, stars will start with no extra information when they become selected again.

◆ clear

static void StelMainScriptAPI::clear ( const QString & state = "natural" )

staticslot

Preset states:

natural : azimuthal mount, atmosphere, landscape, no lines, labels or markers
starchart : equatorial mount, constellation lines, no landscape, atmosphere etc. labels & markers on.
deepspace : like starchart, but no planets, no eq.grid, no markers, no lines.
galactic : like deepspace, but in galactic coordinate system.
supergalactic : like deepspace, but in supergalactic coordinate system.
Parameters

state the name of a preset state.

◆ setDate

static void StelMainScriptAPI::setDate	(	const QString &	dateStr,

Parameters

dateStr

Defines the date or offset to use. Possible formats:

Date and time according to ISO 8601, without time zone, e.g., "2008-03-24T13:21:01"
Use "now" to set Stellarium's time to the system's (presumably) real time.
Specify an offset in the form <sign>

<unit> to set the date relative to its current value. <unit> may be one of second, minute, hour, day, sol, week, month, year, with a plural 's' optionally appended, e.g., "+3.25 days", " - 1 year".

Use "now" followed by an offset to set the date relative to the system's current value, e.g., "now+1hour".

You may append "sidereal" to use units derived from the length of a sidereal day, e.g., "now +2days sidereal".

Note: When sidereal time is used, the length of time for each unit is dependent on the current planet. By contrast, when sidereal time is not specified (i.e., solar time is used) the value is conventional so that 1 day means 1 Earth Solar day.

Parameters

spec	May be "local" or "utc". Only has an effect when an ISO format string is used. Defaults to "utc".
dateIsDT	set to true indicates that the given date is formulated in Dynamical Time, i.e. with DeltaT added.

Note: For fully compatible behaviour of this function with versions 0.11.4 or earlier you should call core.setDeltaTAlgorithm("WithoutCorrection"); before running core.setDate(); for disabling DeltaT correction.; Starting with version 0.13.2 all relative dates are set without DeltaT correction.; Starting with version 0.14.0 the Boolean argument has a different meaning and default!

This resets the position in the sound to the start so that subsequent playSound calls will start from the beginning.

Parameters

id	the identifier used when loadSound was called

◆ stopVideo

void StelMainScriptAPI::stopVideo ( const QString & id )

slot

This resets the position in the video to the start so that subsequent playVideo() calls will start from the beginning.

Parameters

id	the identifier used when loadVideo() was called

◆ wait

void StelMainScriptAPI::wait ( double t )

slot

Parameters

t	the number of seconds to wait

◆ waitFor

void StelMainScriptAPI::waitFor	(	const QString &	dt,
		const QString &	spec = `"utc"`
	)

slot

This function will take into account the rate (and direction) in which simulation time is passing. e.g. if a future date is specified and the time is moving backwards, the function will return immediately. If the time rate is 0, the function will not wait. This is to prevent infinite wait time.

Parameters

dt	the date string to use, format like "2012-06-06T4:44:00" or "-1428-03-04T22:23:45"
spec	"local" or "utc"
