void LoadConfig ( const tinyxml2::XMLElement *  _pluginElem)
override

◆ newProgress

void newProgress ( )
signal

Notify that progress has advanced in the log file.

◆ OnDrop

void OnDrop ( double  _value)
slot

Callback in Qt thread when the slider is released.

[in]_valueThe current value of the slider, from 0 to 1, inclusive

◆ OnTimeEntered

void OnTimeEntered ( const QString &  _time)
slot

Callback when a time is entered by the user.

Parameters
[in]_timeThe time in format dd hh:mm:ss.nnn

◆ Update()

void Update ( const UpdateInfo _info,
EntityComponentManager _ecm 
)
overridevirtual

Update callback called every time the system is stepped. This is called at an Ignition transport thread, so any interaction with Qt should be done through signals and slots.

Parameters
[in]_infoCurrent simulation information, such as time.
[in]_ecmMutable reference to the ECM, so the system can read and write entities and their components.
