Rectangles are a - special case of Polygon with exactly 4 vertices and 4 "straight" edges. In - this case, "straight" means that the top-left point has the same latitude - as the top-right point (the top edge), and the bottom-left point has the - same latitude as the bottom-right point (the bottom edge). Similarly, the - points on the left side have the same longitude, and the points on the - right side have the same longitude. - - To specify the rectangle, it requires a \l topLeft and \l bottomRight point, - both given by a \l {coordinate}. - - By default, the rectangle is displayed with transparent fill and a 1-pixel - thick black border. This can be changed using the \l color, \l border.color - and \l border.width properties. - - \note Similar to the \l MapPolygon type, MapRectangles are geographic - items, thus dragging a MapRectangle causes its vertices to be recalculated - in the geographic coordinate space. Apparent stretching of the item - occurs when dragged to the a different latitude, however, its edges - remain straight. - - \section2 Performance - - MapRectangles have a rendering cost identical to a MapPolygon with 4 - vertices. - - Like the other map objects, MapRectangle is normally drawn without a smooth - appearance. Setting the \l opacity property will force the object to be - blended, which decreases performance considerably depending on the hardware - in use. - - \section2 Example Usage - - The following snippet shows a map containing a MapRectangle, spanning - from (-27, 153) to (-28, 153.5), near Brisbane, Australia. The rectangle - is filled in green, with a 2 pixel black border. - - \code - Map { - MapRectangle { - color: 'green' - border.width: 2 - topLeft { - latitude: -27 - longitude: 153 - } - bottomRight { - latitude: -28 - longitude: 153.5 - } - } - } - \endcode - - \image api-maprectangle.png -*/ - -/*! - \qmlproperty bool QtLocation::MapRectangle::autoFadeIn - - This property holds whether the item automatically fades in when zooming into the map - starting from very low zoom levels.
