|
* @brief The MapObjectIndicatorImpl can be used to ease the locating of an object.
|
|
* The MapObjectIndicatorImpl can by parametrized with just the UniqueMapId to point to.
|
|
* updateView() will do the rest for you:
|
|
* - retrieve the object to point to,
|
|
* - get the bounding box of that object and
|
|
* - create an indicator from the current center of the map to the object.
|
|
* \note <b> If the object to point to disappears, you are responsible for removing the MapObjectIndicatorImpl! </b>
|
|
*
|
|
* A class instance consists of the following logical elements:
|
|
* - mainGraphicalObject (GraphicalObjectPath displaying the line with arrowhead)
|
|
* - m_pictureMarker of type GraphicalObjectPictureMarker / Image to show circle at the center of the map.
|
|
* - mainGraphicalObjectText (displaying the text/name/identifier)
|
|
* - tacticalAppearance (irrelevant)
