Qt Location API 仍然可用吗？

Question

在Qt Location API page at Nokia网站，the link to SDK's download需要使用我在他们网站上的现有帐户登录，但一直说“正在唱歌……”并且再也没有回来。有人有想法吗？ Nokia/Degia 是否关闭了该项目？

Qt Location 本来是 Qt 5.0 的一个完整的附加模块，但它被删减并重新设计。从 Qt 5.5 开始，Qt Location is listed as a Technology Preview ，这表明它将很快成为一个标准模块。

Here's a couple quotes关于它为何被删减以及如何重新加工:

Unfortunately, some modules either lost their maintainers, or their quality was not up to scratch, so they were excluded from the Qt 5.0.0 release. Qt Location did not make the cut, and its code base still requires lots of cleaning up.

The plan is to include those modules when they are ready though.

A lot of the components in Qt Location have been converted to value types. Previously components such as Coordinate, GeoCircle, GeoRectangle etc were QObjects. Now they are value types which provides a much nicer API.

顺便一提，Nokia 不再参与 Qt 的开发。我不建议从诺基亚下载旧的 SDK。您可以从 http://qt.io/download 获取最新版本
