Detailed Description

GKGeoObject is the base class for all the objects with a graphical representation. They are stored in layers (GKLayer) and these layers are in the GKGeoModel.

When creating a geo object with its new command, the graphical object will be automatically added to the geo model. When creating a geo object with GKSystem::newObject, it will not be added to the geomodel automatically. It will not be visible util it is added. Add it using the GKGeoModel::add.

Objects are selected by model, what means that a selected object is selected in all the views in where it appears (2D and/or 3D).

An object can have a mark (or more than one) using GKGeoObject::setMark to mark it with a special color and/or shape (depending of the object).

An object can be grouped with other ones in a group (GKGeoObjectGroup). In this case the group and not the individual objects will be manipulated.

An object can have object on top of it (GKGeoObject::getTopObjects). These objects bellows to this bottom object and are translated, rotated and deleted with it.

Member Function Documentation

add()

void GKGeoModel::add	(	GKLayer *	layer,

	)

Adds an object to the geo model in a specific layer (the layer cannot be None).

GKViewBookmark *

abookmark

)

Add a bookmark to the geo model, the pointer is adopted.

addMode()

void GKGeoModel::addMode

(

GKViewMode *

)

Add a new mode: the mode is adopted.

addStyle()

void GKGeoModel::addStyle

(

GKViewModeStyle *

)

Adds a new style: the style is adopted.

anyStyleUsesThisColumn()

bool GKGeoModel::anyStyleUsesThisColumn

(

const GKColumn *

)

const

A style using this column is present ?

changeLayer()

void GKGeoModel::changeLayer	(	GKLayer *	,
		GKLayer *	,
		GKGeoObject *
	)

Changes the layer of an object.

deleteBookmarks()

void GKGeoModel::deleteBookmarks

(

)

Removes and deletes all the bookmarks from the model.

expandWorld() [1/2]

void GKGeoModel::expandWorld	(	const GKBBox &	,
		const GKPoint &	= GKPoint::zero
	)

Expand the world.

expandWorld() [2/2]

void GKGeoModel::expandWorld	(	const GKPoint &	,
		const GKPoint &	= GKPoint::zero
	)

Expand the world.

findClosestObject()

GKGeoObject * GKGeoModel::findClosestObject	(	const GKPoint &	p,
		GKType *	type = nullptr,
		double	distance = -1.0
	)

Returns the closest object to a point. If a type is specified, only objects of that type will be considered.

findClosestObjects()

QVector< GKGeoObject * > GKGeoModel::findClosestObjects	(	const GKPoint &	p,
		double	maxDistance,
		GKType *	type = nullptr
	)		const

Returns the closest objects to a point within the maxDistance range. Maximum Distance must be >= 0. If a type is specified, only objects of that type will be considered.

findLayer()

GKLayer * GKGeoModel::findLayer

(

const QString &

)

find a layer using its internal name (that is unique)

findMode()

GKViewMode * GKGeoModel::findMode	(	const QString &	iname,
		bool	automatic
	)

Find a mode by its internal name. If automatic is true only looks for automatic modes, if false for user-defined modes.

findStyle()

GKViewModeStyle * GKGeoModel::findStyle

(

const QString &

)

Finds a style by its internal name.

getActiveLayer()

GKLayer * GKGeoModel::getActiveLayer

(

bool

getAnything = false

)

Return the current active layer (the layer that has the focus in the GGui) or None if no layer is active. If getAnything is true it will return a layer (any) when no layer is active.

getBBox()

GKBBox GKGeoModel::getBBox

(

)

const

Returns the bbox (slow: the bbox is calculated)

getBookmarks()

const QVector< GKViewBookmark * > & GKGeoModel::getBookmarks

(

)

const

Returns all the bookmarks.

getCoordinateTranslator()

GKCoordinateTranslator & GKGeoModel::getCoordinateTranslator

(

)

Coordinate translation from/to degrees and meters.

getDefaultCS()

QString GKGeoModel::getDefaultCS

(

)

const

The coordinate system for this model. The default value is EPSG:32601 that corresponds to WGS 84 / UTM zone 1N.

(

)

const

Returns all the layers in this geomodel

getNetworkNodesInfo()

QPair< uint, uint > GKGeoModel::getNetworkNodesInfo

(

)

const

Returns the total number of nodes in the network. The first part of the pair is the number of nodes, the second part is the number of nodes that are evaluated as intersections.

getSectionsLength()

const

Returns the sum of lengths for all sections in the whole network (in m) or for the sections located inside the polygon. The first part of the pair has the sum of lengths (in 3D) by section, the second part of the pair has the sum of lengths by lane including side lanes (in 2D).

A list of selected objects (common for all the views)

getTotalNetworkLength()

Returns the current world size (min and max coordinates)

inverseSelection()

void GKGeoModel::inverseSelection

remove()

bool GKGeoModel::remove	(	GKLayer *	,
