Description

Methods

	`constructor Create();`
Constructor.

	`destructor Destroy; override;`
Destructor.

procedure Add(const Item: TGPSPosition);

Add GPS position to collection.

Parameters

Item: GPSPosition item.

procedure Insert(index: Integer; const Item: TGPSPosition);

Insert GPS position into collection.

Parameters

index: Index, where the position is inserted.
Item: GPSPosition item.

procedure Delete(index: Integer);

Delete position from collection.

Parameters

index: Index, where the position is deleted from.

	`procedure Clear;`
Remove all positions from collection.

Properties

	`property Count: Integer read GetCount;`
GPSPosition count.

	`property Items[index:Integer]: TGPSPosition read GetItem write SetItem;`
GPSPosition items.

	`property Name: String read fName write fName;`
Path name.

	`property StrokeColor: TColor read fStrokeColor write fStrokeColor;`
Color of the stroke.

	`property StrokeOpacity: Double read fStrokeOpacity write fStrokeOpacity;`
Opacity of the stroke.

	`property StrokeWeight: Integer read fStrokeWeight write fStrokeWeight;`
Weight of the stroke.

	`property FillColor: TColor read fFillColor write fFillColor;`
Fill color of the shape.

	`property FillOpacity: Double read fFillOpacity write fFillOpacity;`
Opacity of the shape.

	`property GeodesicStatus: Boolean read fGeodesicStatus write fGeodesicStatus;`
Indicates whether the segments of the polyline should be drawn as geodesics, as opposed to straight lines on the Mercator projection. A geodesic is the shortest path between two points on the Earth's surface. The geodesic curve is constructed assuming the Earth is a sphere.

	`property PathType: TPathType read fPathType write fPathType;`
Path type (polygon or polyline).

	`property Visible: Boolean read fVisible write fVisible default true;`
Indicates that the path is visible on the map.
