QGeoTiledMapRequest::QGeoTiledMapRequest ()

Constructs a new tiled map request.

QGeoTiledMapRequest::QGeoTiledMapRequest ( QGraphicsGeoMap::ConnectivityMode connectivityMode, QGraphicsGeoMap::MapType mapType, qreal zoomLevel, int row, int column, const QRect & tileRect )

Constructs a new tiled map request.

At a zoom level of z the world is represented as a 2^z by 2^z grid of tiles.

This tiled map request represents a request for the tile at row row and column column at zoom level zoomLevel and type mapType.

The request will use connectivity mode connectivityMode when accessing the map data.

The rectangle that the tile occupies on the map at the maximum zoom level is also given as tileRect.

This function was introduced in Qt Mobility 1.1.

QGeoTiledMapRequest::QGeoTiledMapRequest ( const QGeoTiledMapRequest & other )

Constructs a tiled map request from the contents of other.

This function was introduced in Qt Mobility 1.1.

QGeoTiledMapRequest::~QGeoTiledMapRequest ()

Destroys this tiled map request.

int QGeoTiledMapRequest::column () const

Returns the column of the requested tile.

At a zoom level of z the world is represented as a 2^z by 2^z grid of tiles, and so the column will be between 0 and 2^z - 1.

This function was introduced in Qt Mobility 1.1.

QGraphicsGeoMap::ConnectivityMode QGeoTiledMapRequest::connectivityMode () const

Returns the connectivity mode of the tile request.

This function was introduced in Qt Mobility 1.1.

QGraphicsGeoMap::MapType QGeoTiledMapRequest::mapType () const

Returns the map type of the requested tile.

This function was introduced in Qt Mobility 1.1.

int QGeoTiledMapRequest::row () const

Returns the row of the requested tile.

At a zoom level of z the world is represented as a 2^z by 2^z grid of tiles, and so the row will be between 0 and 2^z - 1.

This function was introduced in Qt Mobility 1.1.

QRect QGeoTiledMapRequest::tileRect () const

Returns the rectangle that the tile covers on the map at the maximum zoon level.

At a zoom level of z the world is represented as a 2^z by 2^z grid of tiles. If m is the maximum zoom level and the tiles are t by t pixel squares, then the entire world could be viewed as a 2^m * t by 2^m * t pixel image.

The rectangle returned is specified relative to the pixel coordinates of the map at the maximum zoom level.

This function was introduced in Qt Mobility 1.1.

int QGeoTiledMapRequest::zoomLevel () const

Returns the zoom level of the requested tile.

The lower and upper bounds of the zoom level are set by the QGeoMappingManager that created this request.

This function was introduced in Qt Mobility 1.1.

QGeoTiledMapRequest & QGeoTiledMapRequest::operator= ( const QGeoTiledMapRequest & other )

Assigns other to this tiled map request and then returns a reference to this tiled map request.

This function was introduced in Qt Mobility 1.1.

bool QGeoTiledMapRequest::operator== ( const QGeoTiledMapRequest & other ) const

Returns with this tiled map request is equal to other.

This function was introduced in Qt Mobility 1.1.
