c – 是否有QPair课程,但有三个而不是两个？

如 QTBUG-22441所示,开发人员无意添加std :: tuple的Qt模拟. (尽管 QTBUG-3283给了我们希望它可以完成,它的日期是09年12月,而新的报告,带有WONTFIX,是在2015年5月).因此,您需要回退到std :: tuple或者提出自己的数据结构.

引自Marc Mutz：

A hypothetical QTuple wouldn’t do anything differently,anyway,except drain Qt developer resources.

此外,the docs for Qt 5 Algorithms module明确说明如下：

Historically,Qt used to provide functions which were direct equivalents of many STL algorithmic functions. Starting with Qt 5.0,you are instead encouraged to use directly the implementations available in the STL; most of the Qt ones have been deprecated (although they are still available to keep the old code compiling).

因此,在使用Qt 5进行编程时使用STL是正式鼓励的,如果它成为必需品.
