Detailed Description
A geometry for tracking objects made of (time, coordinates) pairs.
GeoDataTrack implements the Track tag defined in Google's extension of the Open Geospatial Consortium standard KML 2.2 at https://developers.google.com/kml/documentation/kmlreference#gxtrack .
A track is made of points, each point has a coordinates and a time value associated with the coordinates. New points can be added using the addPoint() method. The coordinates of the tracked object at a particular time can be found using coordinatesAt(), you can specify if interpolation should be used using the setInterpolate() function.
By default, a LineString that passes through every coordinates in the track is drawn. You can customize it by changing the GeoDataLineStyle, for example if the GeoDataTrack is the geometry of feature, you can disable the line drawing with:
For convenience, the methods appendCoordinates() and appendWhen() are provided. They let you add points by specifying their coordinates and time value separately. When N calls to one of these methods are followed by N calls to the other, the first coordinates will be matched with the first time value, the second coordinates with the second time value, etc. This follows the way "coord" and "when" tags inside the Track tag should be parsed.

◆ addPoint()
void Marble::GeoDataTrack::addPoint | ( | const QDateTime & | when, |
const GeoDataCoordinates & | coord | ||
) |
Add a new point with coordinates coord
associated with the time value when
.
Definition at line 219 of file GeoDataTrack.cpp.
◆ appendAltitude()
void Marble::GeoDataTrack::appendAltitude | ( | qreal | altitude | ) |
Add altitude information to the last appended coordinates.
Definition at line 247 of file GeoDataTrack.cpp.

◆ coordinatesAt() [1/2]
GeoDataCoordinates Marble::GeoDataTrack::coordinatesAt | ( | const QDateTime & | when | ) | const |
If interpolate() is true, return the coordinates interpolated from the time values before and after when
, otherwise return the coordinates of the point with the closest time value less than or equal to when

◆ extendedData()
const GeoDataExtendedData & Marble::GeoDataTrack::extendedData | ( | ) | const |
Return the ExtendedData assigned to the feature.
Definition at line 324 of file GeoDataTrack.cpp.
◆ firstWhen()
QDateTime Marble::GeoDataTrack::firstWhen | ( | ) | const |
Return the time value of the first point in the track, or an invalid QDateTime if the track is empty.
Definition at line 124 of file GeoDataTrack.cpp.
◆ interpolate()
bool Marble::GeoDataTrack::interpolate | ( | ) | const |
Returns true if coordinatesAt() should use interpolation, false otherwise.
The default is false.

- setInterpolate, coordinatesAt
Definition at line 110 of file GeoDataTrack.cpp.
◆ lastWhen()
QDateTime Marble::GeoDataTrack::lastWhen | ( | ) | const |

◆ lineString()
const GeoDataLineString * Marble::GeoDataTrack::lineString | ( | ) | const |
Return the GeoDataLineString representing the current track.
Definition at line 313 of file GeoDataTrack.cpp.
◆ nodeType()
|
overridevirtual |
Provides type information for downcasting a GeoNode.
Implements Marble::GeoNode.

void Marble::GeoDataTrack::removeBefore | ( | const QDateTime & | when | ) |
Remove all points from the track whose time value is less than when
.
Definition at line 280 of file GeoDataTrack.cpp.
◆ setExtendedData()
void Marble::GeoDataTrack::setExtendedData | ( | const GeoDataExtendedData & | extendedData | ) |
Sets the ExtendedData of the feature.
