Detailed Description

Provide script API for Stellarium global functions.

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);

Definition at line 37 of file StelMainScriptAPI.hpp.

  • "now" (set sim time to real time)
  • relative, e.g. "+ 4 days", "-2 weeks". can use these units: seconds, minutes, hours, days, weeks, months, years. You may also append " sidereal" to use sidereal days and so on. You can also use "now" at the start. For example: "now + 3 hours sidereal"
Note
you must use the plural all the time, even when the number of the unit is 1. i.e. use "+ 1 days" not "+1 day".
