This driver illustrates the use of state views to access sim data. When the DtAttachManager emits its attachment changed signal, the DtStateViewDriver will get a state view onto the currently attached entity and print out some information from the sim state at a 1hz update rate.

Member Function Documentation

virtual const std::string& DtStateViewDriver::className ( ) const

virtual

Get the class name as a string.

Implements makVrv::DtDriver.

virtual bool DtStateViewDriver::onStart ( )

protectedvirtual

When late-joining display engines are connected to the master display engine, all drivers are stopped and restarted. It is critical to implement these methods correctly to make late-joining display engines work correctly.

Called when the driver is started by the display engine Restores state that existed the last time the driver was stopped

Implements makVrv::DtDriver.

virtual bool DtStateViewDriver::onStop ( )

protectedvirtual

Called when the driver is stopped by the display engine.

Implements makVrv::DtDriver.

virtual void DtStateViewDriver::slot_displayEngineAdded ( const DtDeRecord & igRecord )

protectedvirtual

Called when a display engine is connected; restarts the driver.

Reimplemented from makVrv::DtDriver.

virtual bool DtStateViewDriver::onTick ( )

protectedvirtual

Stub implementation since this driver doesn't have anything that needs updating.

Implements makVrv::DtDriver.

virtual void DtStateViewDriver::handleAttachToChanged ( DtObserver * observer )

protectedvirtual

Called by signal when an observer's attachment changes; used as a cue to start listening to the attached entity's state.

DtSimEntry* DtStateViewDriver::findSimEntry ( DtUniqueID elementId )

protected

Find a sim entry corresponding to a visual object's unique element ID.

void DtStateViewDriver::disableCurrentStateView ( )

protected

Disables the currently active state view.

virtual void DtStateViewDriver::slot_stateViewUpdated ( DtVrlinkEntityStateView * stateView )

protectedvirtual

Called when the currently active state view emits an update.

virtual void DtStateViewDriver::slot_simObjectRemoved ( DtSimObjectEntry & )

protectedvirtual

Called when a sim object is removed, so its state view can be removed from the cache if present.
