makVrv::DtAttachableHatTextUpdater Class Reference

A DtAttachableHatTextUpdater is used to update a HAT text object that can be positioned in the scene by (possibly) attaching it to another object. This updater extends the usual updater paradigm in that it not only positions the object, but also calculates and sets the actual HAT text. To do so, the scene object must have a model of type DtWidgetLabel in its model list.

virtual void makVrv::DtAttachableHatTextUpdater::update ( double  simTime )

virtual

Update the scene object.

virtual void makVrv::DtAttachableHatTextUpdater::setUseHighestTerrainLod ( bool  useHighest )

virtual

Set whether the line is to currently visible terrain LOD or to highest available terrain LOD.

virtual bool makVrv::DtAttachableHatTextUpdater::useHighestTerrainLod ( ) const

virtual

Get whether line is to currently visible terrain LOD or to highest available terrain LOD.

virtual void makVrv::DtAttachableHatTextUpdater::setTextProportion ( double  proportion )

virtual

The location along the HAT line, from 0 (top) to 1 (bottom)

virtual void makVrv::DtAttachableHatTextUpdater::setDisplayUnitCollectionName ( const DtUnicode &  displayUnitCollectionName )

virtual

Set the display unit collection that this updater will use.

Parameters

displayUnitCollectionName

The name of the collection the updater will look for display units in This updater class makes use of the following display units: 'Altitude'

virtual void makVrv::DtAttachableHatTextUpdater::updateWidgetLabel ( DtWidgetLabel *  widgetLabel, double  distanceInMeters  )

protectedvirtual

Update the text in the widget label.

virtual DtVector makVrv::DtAttachableHatTextUpdater::findIntersect ( const DtVector &  start, const DtVector &  up  )

protectedvirtual

Attempt a terrain intersection. Note that isect will always be filled in. If start is below sea level, the point at sea level will be returned. If above sea level, an intersection will be attempted. If it fails, isect will be filled in with start. If it succeeds, doIntersect will check for a dynamic ocean layer. If one exists and the intersection is below it, the point at sea level is returned.

virtual void makVrv::DtAttachableHatTextUpdater::on_displayUnitChanged ( )

protectedvirtual

Called when signals indicating display units settings has changed are emitted.
