QCollator 被初始化采用 QLocale and an optional collation strategy. It tries to initialize the collator with the specified values. The collator can then be used to compare and sort strings in a locale dependent fashion.
A QCollator object can be used together with template based sorting algorithms such as std::sort to sort a list of QStrings.
In addition to the locale and collation strategy, several optional flags can be set that influence the result of the collation.
Move constructor. Moves from other into this collator.
Note that a moved-from QCollator can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.
Creates a copy of other .
构造 QCollator 从 locale .
另请参阅 setLocale ().
Constructs a QCollator using the system's default collation locale.
该函数在 Qt 5.13 引入。
另请参阅 setLocale () 和 QLocale::collation ().
Move-assigns from other to this collator.
Note that a moved-from QCollator can only be destroyed or assigned to. The effect of calling other functions than the destructor or one of the assignment operators is undefined.
赋值 other to this collator.
Destroys the collator.
Returns case sensitivity of the collator.
另请参阅 setCaseSensitivity ().
比较 s1 with s2 .
Returns an integer less than, equal to, or greater than zero depending on whether s1 sorts before, with or after s2 .
该函数在 Qt 5.13 引入。
这是重载函数。
比较 s1 with s2 .
Returns an integer less than, equal to, or greater than zero depending on whether s1 sorts before, with or after s2 .
这是重载函数。
比较 s1 with s2 .
Returns an integer less than, equal to, or greater than zero depending on whether s1 sorts before, with or after s2 .
这是重载函数。
比较 s1 with s2 . len1 and len2 specify the lengths of the QChar arrays pointed to by s1 and s2 .
Returns an integer less than, equal to, or greater than zero depending on whether s1 sorts before, with or after s2 .
返回
true
if punctuation characters and symbols are ignored when determining sort order.
另请参阅 setIgnorePunctuation ().
Returns the locale of the collator.
另请参阅 setLocale ().
返回
true
if numeric sorting is enabled, false otherwise.
另请参阅 setNumericMode ().
Sets the case sensitivity of the collator.
另请参阅 caseSensitivity ().
若 on is set to true, punctuation characters and symbols are ignored when determining sort order.
The default is locale dependent.
注意： This method is not currently supported if Qt is configured to not use ICU on Linux.
另请参阅 ignorePunctuation ().
Sets the locale of the collator to locale .
另请参阅 locale ().
Enables numeric sorting mode when on is set to true.
This will enable proper sorting of numeric digits, so that e.g. 100 sorts after 99.
By default this mode is off.
另请参阅 numericMode ().
Returns a sortKey for string .
Creating the sort key is usually somewhat slower, than using the compare () methods directly. But if the string is compared repeatedly (e.g. when sorting a whole list of strings), it's usually faster to create the sort keys for each string and then sort using the keys.
注意： Not supported with the C (a.k.a. POSIX) locale on Darwin.
Swaps this collator with other 。此函数非常快，且从不失败。
