127 QCollator is initialized with a QLocale and an optional collation strategy. It tries to -
128 initialize the collator with the specified values. The collator can then be used to compare -
129 and sort strings in a locale dependent fashion. -
130 -
131 A QCollator object can be used together with template based sorting algorithms such as std::sort -
132 to sort a list of QStrings. -
133 -
134 In addition to the locale and collation strategy, several optional flags can be set that influence -
135 the result of the collation. -
