There is no equivalent in QML. But, you can easily create your own widget with a TextField and a custom validator:

In QML:

TextField 
 text : "01/01/1970 00:00:00"
 inputMask: "99/99/9999 99:99:99"
 validator: DateTimeValidator 
 

In C++:

// datetimevalidator.h
#include <QValidator>
#include <QDateTime>

class DateTimeValidator: public QValidator

public:
 DateTimeValidator();

 State validate(QString& input, int& pos) const;
;

// datetimevalidator.cpp
#include <datetimevalidator.h>
DateTimeValidator::DateTimeValidator(): QValidator()


QValidator::State DateTimeValidator::validate(QString& input, int& pos) const

 QDateTime dt = QDateTime::fromString(input, "MM/dd/yyyy HH:mm:ss");
 if (dt.isNull()) // If null, the input cannot be parsed
 
 return QValidator::Invalid;
 
 return QValidator::Acceptable;

In the main(), register your validator to be able to use it in QML:

#include "datetimevalidator.h"

int main(int argc, char** argv)

 QApplication app(argc, argv);
 qmlRegisterType<DateTimeValidator>("my.components", 1, 0, "DateTimeValidator");
...

  Add #include <QValidator>. Create a header file (.h). You can move the implementation in a source file, if you want.
