QGeoCircle ¶

概要 ¶

详细描述 ¶

The circle is defined in terms of a QGeoCoordinate which specifies the center of the circle and a qreal which specifies the radius of the circle in meters.

The circle is considered invalid if the center coordinate is invalid or if the radius is less than zero.

This class is a Q_GADGET since Qt 5.5. It can be directly used from C++ and QML .

class QGeoCircle ¶

QGeoCircle(other)

PySide2.QtPositioning.QGeoCircle. translate ( degreesLatitude , degreesLongitude ) ¶

参数

• degreesLatitude – double

• degreesLongitude – double

Translates this geo circle by degreesLatitude northwards and degreesLongitude eastwards.

Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.

参数

• degreesLatitude – double

• degreesLongitude – double

返回类型

QGeoCircle

Returns a copy of this geo circle translated by degreesLatitude northwards and degreesLongitude eastwards.

Negative values of degreesLatitude and degreesLongitude correspond to southward and westward translation respectively.
