QVariant StelPropertyMgr::getStelPropertyValue ( const QString &  id) const
the current value of the StelProperty with the ID id, or an invalid QVariant when no property with the given ID is found.
void StelPropertyMgr::registerObject ( QObject *  obj)

The object must have an unique QObject::objectName, and this name should never change after registering. For all properties on this object, a StelProperty with an ID in the format <objectName>.<propertyName> is generated.

StelProperty* StelPropertyMgr::registerProperty ( const QString &  id,
QObject *  target,
const char *  propertyName 
idThe identifier of the property. Must be unique, app will exit otherwise. It should follow the naming conventions as described in StelProperty.
targetThe QObject which contains the property.
propertyNameThe name of the Q_PROPERTY on the target which should be linked
a new StelProperty linking to the property with name propertyName on the target object
bool StelPropertyMgr::setStelPropertyValue ( const QString &  id,
const QVariant &  value 
) const
true when the value of the StelProperty with the ID id has been successfully changed, and false if the value change failed or when no property with the given ID is found.
void StelPropertyMgr::stelPropertyChanged ( StelProperty prop,
const QVariant &  value 
propThe property that was changed
valueThe new value of the property
