Detailed Description

A polyline that will be drawn on the map.

A polyline is a series of connected line segments going through a series of points.

Constructor & Destructor Documentation

◆ Polyline() [1/2]

Wt::WLeafletMap::Polyline::Polyline	(	const std::vector< Coordinate > &	points,
		const WPen &	pen = `WPen()`,
		const WBrush &	brush = `WBrush()`
	)

explicit

Create a new polyline going trough the given points.

Creates a new polyline going through the given points, drawn with the given pen and filled with the given brush.

◆ Polyline() [2/2]

Wt::WLeafletMap::Polyline::Polyline	(	const std::vector< Coordinate > &	points,
		const WBrush &	brush
	)

explicit

Create a new polyline going trough the given points.

Creates a new polyline going through the given points and filled with the given brush.

Member Function Documentation

◆ createItemJS()

void Wt::WLeafletMap::Polyline::createItemJS	(	WStringStream &	ss,
		WStringStream &	postJS,
		long long	id
	)

overrideprotectedvirtual

Writes the JS code to create this item to the stream.

This method should write in ss the JS code that creates the item. The postJS stream can be used to write JS code that should be executed after the item has been created.

Implements Wt::WLeafletMap::AbstractMapItem.

◆ move()

void Wt::WLeafletMap::Polyline::move ( const Coordinate & pos )

overridevirtual

Move the polyline.

This moves the polyline so that its first point is at the given position. The other points are moved by the same offset.

Reimplemented from Wt::WLeafletMap::AbstractMapItem.

◆ points()

const std::vector< Coordinate > & Wt::WLeafletMap::Polyline::points ( ) const

Return the points the polyline goes trough.

See also: setPoints()

◆ setPoints()

void Wt::WLeafletMap::Polyline::setPoints ( const std::vector< Coordinate > & points )

Set the points the polyline go trough.

This sets the points the polyline goes trough to the given list of points.
