Returns

The end time in format dd hh:mm:ss.nnn as a QString.

LoadConfig()

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.

Parameters

[in]	_info	Current simulation information, such as time.
[in]	_ecm	Mutable reference to the ECM, so the system can read and write entities and their components.
