Detailed Description

Basic viewer application for loading and simulating IPSA scenes.

Create an instance of this class to use it for simulating IPSA scenes. The code usually looks like the following example (Note that you have to call SO_PLATFORM::init() before instantiating an IpsaViewer):

 #include "IpsaViewer.h"
 #include <Inventor/Qt/SoQt.h>

 int main (int argc, char ** argv)
     SO_WINDOW parentWidget = SO_PLATFORM::init(argc, argv, argv[0]);
     IpsaViewer viewer("FileToOpen.iv", parentWidget, argv[0]); // create an instance of the IpsaViewer
     viewer.run(); // start the visualisation/simulation
     return 0;

The simulation behaviour can be changed by creating a subclass of IpsaSimulator and using this instead of the default IpsaSimulator instance.

Constructor & Destructor Documentation

IpsaViewer::IpsaViewer ( std::string  filename = "",
SO_WINDOW  parent = NULL,
const char *  name = "IPSA Viewer",
SbBool  embed = TRUE 

The constructor of the IpsaViewer class.
It creates an IpsaSimulator instance and stores it in IpsaViewer::ipsaSimulator. Afterwards the

filename is set on IpsaViewer::ipsaSimulator and the IpsaViewer::window variable is set to parent.
filename name of the file getting opened by IpsaViewer::readSceneryFromFile() (default = "")
parent the parent widget of the viewer (default = NULL)
name name of the viewer (default = "IPSA Viewer")
embed tells if viewer should be embedded (default TRUE)

IpsaViewer::~IpsaViewer (  )  [virtual]

The virtual destructor of the IpsaViewer class. It deletes IpsaViewer::ipsaSimulator.

Member Function Documentation

void IpsaViewer::createViewerButtons ( SO_WINDOW  parent,
SbPList *  buttonlist 
) [protected, virtual]

Add custom Qt buttons for scheduling the simulation, for showing the IpsaViewer::dialog and for resetting the simulation.

parent parent Qt widget
buttonlist a coin list containing all buttons already created

bool IpsaViewer::getVerbosity (  ) 

true if verbosity of IpsaViewer::ipsasimulator is on, false otherwise

Definition at line 319 of file IpsaViewer.cpp.

References IpsaSimulator::getVerbosity(), and ipsaSimulator.

bool IpsaViewer::isScheduled (  ) 

true if the worlds in the scenegraph are scheduled and false otherwise

Definition at line 299 of file IpsaViewer.cpp.

References ipsaSimulator, and IpsaSimulator::isScheduled().

void IpsaViewer::reloadSimulation (  )  [slot]

This method creates a new scenegraph by calling IpsaSimulator::reload() on IpsaViewer::ipsaSimulator and afterwards sets it on IpsaViewer::examinerViewer.

void IpsaViewer::resetSimulation (  )  [slot]

Resets the simulation by calling IpsaSimulator::reset() in IpsaViewer::ipsaSimulator.

bool IpsaViewer::run ( bool  doSchedule = false,
std::string  scenerySaveFile = "" 

This method calls IpsaSimulator::reload() to initialise the simulator and create a scenegraph.
Afterwards the scenegraph is saved to the file scenerySaveFile if the parameter is not empty. When everything was set up correctly the ExaminerViewer gets started.

doSchedule schedules the worlds at startup if true, or not if false
scenerySaveFile save the loaded scenegraph to this file if parameter is not an empty string
true if the scenegraph was built correctly and the visualisation finished

false if an error occured before the visualisation could be run

void IpsaViewer::saveSceneToFile (  )  [slot]

Save current inventor scenegraph to file at location IpsaViewer::saveFile. Do nothing if IpsaViewer::saveFile is empty.

void IpsaViewer::setSceneryFilename ( const std::string &  newFile  ) 

This method sets newFile as the new filename on IpsaViewer::ipsaSimulator. After calling IpsaViewer::reload() the new file is read.

void IpsaViewer::setVerbosity ( bool  verbosityOn = true  ) 

Sets the verbosity flag on IpsaViewer::ipsaSimulator.

verbosityOn true for turning verbosity on, false for turning it of (default = true)

void IpsaViewer::showDialog (  )  [slot]

Shows the IpsaViewer::dialog if it isn't on screen or raises it otherwise.
