Constructor & Destructor Documentation

SimClock()

SimClock::SimClock ( QObject * parent = nullptr, const KStarsDateTime & when = KStarsDateTime::currentDateTimeUtc() )

explicit

Constructor.

Parameters

parent	parent object for the clock
when	the date/time to which the SimClock should be initialized in UTC

Definition at line 18 of file simclock.cpp.

Member Function Documentation

clockToggled

void SimClock::clockToggled ( bool )

signal

This is an signal that is called on either clock start or clock stop with an appropriate boolean argument.

Required so that we can bind it to KToggleAction::slotToggled(bool)

isActive()

bool SimClock::isActive

(

)

Whether the clock is active or not is a bit complicated by the introduction of "manual mode".

In manual mode, SimClock's internal timer is stopped, because the clock is ticked manually when the current update has finished. So, if ManualMode is true, then isActive() checks whether ManualActive is true. Otherwise, it checks whether the timer is running.

Returns

true if the Simulation clock is actively running.

Definition at line 96 of file simclock.cpp.

isManualMode()

bool SimClock::isManualMode ( ) const

inline

Manual Mode is a new (04/2002) addition to the SimClock.

It is intended to be activated for large timesteps, when we want each frame drawn to the screen to be precisely Scale seconds later than the previous frame. (i.e., if the timescale is 1 year, then each successive frame should be 1 year later than the previous frame). ManualMode accomplishes this by stopping the internal timer and allowing the clock to be advanced manually (the manualTick() slot is called at the end of each KStars::updateTime()).

Returns

whether Manual Mode is active.

Definition at line 66 of file simclock.h.

manualTick

void SimClock::manualTick ( bool force = false, bool backward = false )

slot

Equivalent of tick() for manual mode.

If ManualActive is true, add Scale seconds to the SimClock time. (we may want to modify this slightly...e.g., the number of seconds in a year is not constant (leap years), so it is better to increment the year, instead of adding 31 million seconds. set backward to true to reverse sign of Scale value

Definition at line 83 of file simclock.cpp.

scale()

double SimClock::scale ( ) const

inline

Returns

the current timestep setting

Definition at line 51 of file simclock.h.

scaleChanged

void SimClock::scaleChanged ( float )

signal

The timestep has changed.

setClockScale

void SimClock::setClockScale ( double scale )

slot

DBUS function to set scale of simclock.

setClockScale Set simulation clock scale per second.

Parameters

scale

Scale per second. 1 means normal scale, each 1 simulation second equals 1 real second. Value less than one slows the simulation clock, while values over 1 speeds it up. A scale of 0.5 makes the simulation clock ticks once every 2 actual seconds (or half-ticks per one actual second), while a value of 60 make the simulation clock ticks 60 simulation seconds (1 simulation minute) for every 1 actual second.

Definition at line 169 of file simclock.cpp.

setManualMode()

void SimClock::setManualMode

(

bool

on = true

)

Sets Manual Mode on/off according to the bool argument.

Definition at line 61 of file simclock.cpp.

setNow

Q_SCRIPTABLE Q_NOREPLY void SimClock::setNow ( )

inlineslot

DBUS function to set the current time of the SimClock.

Definition at line 86 of file simclock.h.

setUTC

void SimClock::setUTC ( const KStarsDateTime & newtime )

slot

DBUS function to set the time of the SimClock.

Definition at line 143 of file simclock.cpp.

start

void SimClock::start ( )

slot

DBUS function to start the SimClock.

Definition at line 120 of file simclock.cpp.

stop

void SimClock::stop ( )

slot

DBUS function to stop the SimClock.

Definition at line 104 of file simclock.cpp.

tick

void SimClock::tick ( )

slot

Respond to the QTimer::timeout signal.

Definition at line 32 of file simclock.cpp.

timeAdvanced

void SimClock::timeAdvanced ( )

signal

The clock has ticked (emitted by tick() )

timeChanged

void SimClock::timeChanged ( )

signal

The time has changed (emitted by setUTC() )

utc()

const KStarsDateTime & SimClock::utc ( ) const

inline

Returns

const reference to the current simulation Universal Time.
