Detailed Description

Draws a fixed image into the map.

This class draws a image overlay onto a map, whose upper left and lower right corners lay always on the given coordinates. The methods setBaselevel, setMaxsize and setMinsize have no effect for this class.

Constructor & Destructor Documentation

FixedImageOverlay	(	qreal	x_upperleft,
		qreal	y_upperleft,
		qreal	x_lowerright,
		qreal	y_lowerright,
		QString	filename,
		QString	name = `QString()`
	)

Creates an image overlay which loads and displays the given image file.

Use this contructor to load the given image file and let the point display it. When you want multiple points to display the same image, use the other contructor and pass a pointer to that image.

Parameters

x_upperleft	the coordinate of the upper left corner where the image should be aligned
y_upperleft	the coordinate of the upper left corner where the image should be aligned
x_lowerright	the coordinate of the lower right corner where the image should be aligned
y_lowerright	the coordinate of the lower right corner where the image should be aligned
filename	the file which should be loaded and displayed
name	the name of the image point

FixedImageOverlay	(	qreal	x_upperleft,
		qreal	y_upperleft,
		qreal	x_lowerright,
		qreal	y_lowerright,
		QPixmap	pixmap,
		QString	name = `QString()`
	)

Creates an image overlay which displays the given image.

Use this contructor to display the given image.

Parameters

x_upperleft	the coordinate of the upper left corner where the image should be aligned
y_upperleft	the coordinate of the upper left corner where the image should be aligned
x_lowerright	the coordinate of the lower right corner where the image should be aligned
y_lowerright	the coordinate of the lower right corner where the image should be aligned
pixmap	pointer to the image pixmap
name	the name of the image point

Member Function Documentation

QRectF boundingBox ( )

virtualinherited

returns the bounding box of the point

The Bounding contains the coordinate of the point and its size. The size is set, if the point contains a pixmap or a widget

Returns: the bounding box of the point

Implements Geometry.

References Point::latitude(), and Point::longitude().

QPointF coordinate ( ) const

inherited

returns the coordinate of the point

The x component of the returned QPointF is the longitude value, the y component the latitude

Returns: the coordinate of a point

Referenced by MapControl::setView(), and Point::Touches().

bool Equals ( Geometry * geom )

inherited

returns true if the given Geometry is equal to this Geometry not implemented yet!

Parameters

geom	The Geometry to be tested

Returns: true if the given Geometry is equal to this

void geometryClicked	(	Geometry *	geometry,
		QPoint	point
	)

signalinherited

This signal is emitted when a Geometry is clicked.

A Geometry is clickable, if the containing layer is clickable. The objects emits a signal if it gets clicked

Parameters

geometry	The clicked Geometry
point	-unused-

Referenced by Point::Touches().

bool isVisible ( ) const

inherited

returns true if this Geometry is visible

Returns: true if this Geometry is visible

Referenced by Point::Touches().

qreal latitude ( ) const

inherited

returns the latitude of the point

Returns: the latitude of the point

Referenced by LineString::boundingBox(), and Point::boundingBox().

qreal longitude ( ) const

inherited

returns the longitude of the point

Returns: the longitude of the point

Referenced by LineString::boundingBox(), and Point::boundingBox().

QString name ( ) const

inherited

returns the name of this Geometry

Returns: the name of this Geometry

Referenced by Geometry::setName().

Geometry * parentGeometry ( ) const

inherited

returns the parent Geometry of this Geometry

A LineString is a composition of many Points. This methods returns the parent (the LineString) of a Point

Returns: the parent Geometry of this Geometry

QPen * pen ( ) const

inherited

returns the QPen which is used on drawing

The pen is set depending on the Geometry. A CirclePoint for example takes one with the constructor.

Returns: the QPen which is used for drawing

Referenced by ArrowPoint::ArrowPoint(), CirclePoint::CirclePoint(), LineString::LineString(), ArrowPoint::setPen(), and CirclePoint::setPen().

QPixmap pixmap ( )

inherited

returns the pixmap of the point

Returns: the pixmap of the point

Referenced by FixedImageOverlay::FixedImageOverlay(), and ImagePoint::ImagePoint().

void positionChanged ( Geometry * geom )

signalinherited

A Geometry emits this signal, when its position gets changed.

Parameters

geom	the Geometry

void setBaselevel ( int zoomlevel )

inherited

Sets the zoom level on which the points pixmap gets displayed on full size.

Use this method to set a zoom level on which the pixmap gets displayed with its real size. On zoomlevels below it will be displayed smaller, and on zoom levels thereover it will be displayed larger

See also: setMinsize, setMaxsize

Parameters

zoomlevel the zoomlevel on which the point will be displayed on full size

void setMaxsize ( QSize maxsize )

inherited

sets a maximal size for the pixmap

When the point´s pixmap should change its size on zooming, this method sets the maximal size.

See also: setBaselevel

Parameters

maxsize the maximal size which the pixmap should have

void setMinsize ( QSize minsize )

inherited

sets a minimal size for the pixmap

When the point's pixmap should change its size on zooming, this method sets the minimal size.

See also: setBaselevel

Parameters

minsize the minimal size which the pixmap should have

void setName ( QString name )

inherited

sets the name of the geometry

Parameters

name	the new name of the geometry

References Geometry::name().

QString toString ( )

inherited

returns a String representation of this Geometry

not implemented yet!

Returns: a String representation of this Geometry

bool Touches	(	Point *	click,
		const MapAdapter *	mapadapter
	)

protectedvirtualinherited

returns true if the given Point touches this Point

The collision detection checks for the bounding rectangulars.

Parameters

geom	the other point which should be tested on collision
mapadapter	the mapadapter which is used for calculations

Returns

Implements Geometry.

QWidget * widget ( )

inherited

returns the widget of the point

Returns: the widget of the point
