4.清空字符串 //example 1 QString str="hello world"; str.clear(); qDebug() <<str.size(); str="" ="" example 2="" qstring str="hello world" ;="" str="" qdebug() <<str.size(); ="" 5.字符串比较 int x = QString::compare("aUtO", "AuTo", Qt::CaseInsensitive); // ...
static int QString::localeAwareCompare(const QString &s1, const QString &s2) 作用:按照Locale设定的进行字符串比较 除此之外还有3个重载函数,其中有1个静态函数,功能类似compare()函数; 其中有2个重载函数是在Qt6.0之后引入的: int QString::localeAwareCompare(QStringView other) const [since 6.0] stati...
QString 由两个compare,一个是自身的: int compare(const QString & other, Qt::CaseSensitivity cs = Qt::CaseSensitive) const int compare(QLatin1String other, Qt::CaseSensitivity cs = Qt::CaseSensitive) const int compare(const QStringRef & ref, Qt::CaseSensitivity cs = Qt::CaseSensitive) ...
if (QString::compare(a, b, Qt::CaseInsensitive) == STR_EQUAL) { out << "a, b are equal" << endl; } else { out << "a, b are not equal" << endl; } if (QString::compare(b, c) == STR_EQUAL) { out << "b, c are equal" << endl; } else { out << "b, ...
For example, if you want to compare a QString with a string literal, you can write code like this and it will work as expected:QString str; if (str == "auto" || str == "extern" || str == "static" || str == "register") { // ... }...
字符串存储、字符存储。 1.QString 简介 QString字符串,Qt当中非常重要的一个类。 QString内部的方法非常多,每一个给大家都讲解一遍,那你就睡着了。遵循2/8定律,我把我工作中最常用的API分析给大家。(过多的API会给大家造成困扰) 对于字符串操作可以分为:增、删、查、改 ...
