Member Function Documentation

virtual void makVrv::DtHeadingLineUpdater::update ( DtTime  tNow )

virtual

update the symbol decorations

Implements makVrv::DtTickable.

virtual bool makVrv::DtHeadingLineUpdater::needsUpdate ( DtTime  tNow )

virtual

The check function called by DtTickableManager to verify if an update is required.

If this function returns true, the DtTickableManager will then call update().

Parameters

[in]

tNow

is the current time-stamp.

Return values

true	if this object needs to be ticked.
false	otherwise.

Reimplemented from makVrv::DtTickable.

virtual void makVrv::DtHeadingLineUpdater::setSceneObject ( DtSceneObject *  sceneObject )

virtual
