QString qtTrId(const char *id, int n=-1) const
Definition: context.h:656
Validates an input field for only alphabetic content.
QString genericValidationError(Context *c, const QVariant &errorData=QVariant()) const override
ValidatorAlpha(const QString &field, bool asciiOnly=false, const ValidatorMessages &messages=ValidatorMessages(), const QString &defValKey=QString())
Base class for all validator rules.

QString label(Context *c) const
void defaultValue(Context *c, ValidatorReturnType *result) const
QString value(const ParamsMultiMap &params) const
QString debugString(Context *c) const
static bool validate(const QString &value, bool asciiOnly=false)
Returns true if value only contains alphabetic characters.
The Cutelyst namespace holds all public Cutelyst API.
QString arg(Args &&... args) const const
bool contains(QChar ch, Qt::CaseSensitivity cs) const const
bool isEmpty() const const
void setValue(QVariant &&value)
Stores custom error messages and the input field label.
Contains the result of a single input parameter validation.
