Detailed Description

Main class for objects that should be painted in maps.

Geometry is the root class of the hierarchy. Geometry is an abstract (non-instantiable) class.

This class and the derived classes Point, Curve and LineString are leant on the Simple Feature Specification of the Open Geospatial Consortium.

Member Function Documentation

virtual QRectF boundingBox

(

)

[pure virtual]

returns the BoundingBox

The bounding box in world coordinates

Returns:

the BoundingBox

Implemented in LineString, and Point.

Referenced by Layer::addGeometry(), and Geometry::setVisible().

bool Equals

(

Geometry *

geom

)

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
	)			[signal]

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

returns true if this Geometry is visible

Returns:

true if this Geometry is visible

Referenced by Point::Touches().

QString name

(

)

const

returns the name of this Geometry

Returns:

the name of this Geometry

Geometry * parentGeometry

(

)

const

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

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

void positionChanged

(

Geometry *

geom

)

[signal]

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

Parameters:

geom

the Geometry

void setName

(

QString

name

)

sets the name of the geometry

Parameters:

name

the new name of the geometry

void setVisible

(

bool

visible

)

[virtual, slot]

if visible is true, the layer is made visible

Parameters:

visible

if the layer should be visible

Reimplemented in Point.

References Geometry::boundingBox().

QString toString

(

)

returns a String representation of this Geometry

not implemented yet!

Returns:

a String representation of this Geometry
