georectangle QML Basic Type

The georectangle type is a geoshape that represents a rectangular geographic area. The type is direct representation of a QGeoRectangle. It is defined by a pair of coordinates which represent the top-left and bottom-right corners of the georectangle. The coordinates are accessible from the topLeft and bottomRight attributes.

A georectangle is considered invalid if the top-left or bottom-right coordinates are invalid or if the top-left coordinate is south of the bottom-right coordinate.

The coordinates of the four corners of the georectangle can be accessed with the topLeft, topRight, bottomLeft and bottomRight attributes. The center attribute can be used to get the coordinate of the center of the georectangle. The width and height attributes can be used to get the width and height of the georectangle in degrees. Setting one of these attributes will cause the other attributes to be adjusted accordingly.

Limitations

A georectangle can never cross the poles.

If the height or center of a georectangle is adjusted such that it would cross one of the poles the height is modified such that the georectangle touches but does not cross the pole and that the center coordinate is still in the center of the georectangle.

Example Usage

Use properties of type variant to store a georectangle. To create a georectangle value, use the QtPositioning.rectangle() function:

import QtPositioning 5.2

Item {
    property variant region: QtPositioning.rectangle(QtPositioning.coordinate(-27.5, 153.1), QtPositioning.coordinate(-27.6, 153.2))
}

When integrating with C , note that any QGeoRectangle value passed into QML from C is automatically converted into a georectangle value, and vice-versa.
