Yes. QRegExp was deprecated in Qt 5, replaced by QRegularExpression.

Similarly, QRegExpValidator was replaced by QRegularExpressionValidator.

@JKSH It's getting more verbose with each iteration. Still better to use than std::regex ! 😉

It's getting more verbose with each iteration.

This change makes it consistent with one of Qt's API design principles ("Avoid abbreviations"): https://wiki.qt.io/API_Design_Principles#The_Art_of_Naming

Well... "better than std" is not that hard to achieve, really... 😉

The STL and other std:: APIs seem to be designed for raw performance and compatibility with general templates; they don't seem to be designed for readability and ease-of-use (although things have been improving lots from C++11 onwards)

@JKSH So, renamed. Replaced is not incorrect, but sounds like a bigger change than renamed.

@Bo-Katan Hi and welcome to devnet,

No, it's not a renaming, QRegExp and friend classes have been deprecated in Qt 5 and removed in Qt 6. QRegularExpression and friends are new classes built on top of PCRE.
