Member Data Documentation

ALPHANUMERIC_ONLY

QRegularExpression Qx::RegularExpression::ALPHANUMERIC_ONLY = QRegularExpression(u"^[a-zA-Z0-9]*$"_s, QRegularExpression::CaseInsensitiveOption)

inlinestatic

Matches text that only contains Latin letters and numeric characters.

ANY_NON_HEX

QRegularExpression Qx::RegularExpression::ANY_NON_HEX = QRegularExpression(u"[^a-fA-F0-9 -]"_s, QRegularExpression::CaseInsensitiveOption)

inlinestatic

Matches text that contains at least a single non-hexadecimal character.

HEX_ONLY

QRegularExpression Qx::RegularExpression::HEX_ONLY = QRegularExpression(u"^[a-fA-F0-9]+$"_s, QRegularExpression::CaseInsensitiveOption)

inlinestatic

Matches text that only contains valid hexadecimal characters (case-insensitive).

LETTERS_ONLY

QRegularExpression Qx::RegularExpression::LETTERS_ONLY = QRegularExpression(u"^[a-zA-Z]+$"_s, QRegularExpression::CaseInsensitiveOption)

inlinestatic

Matches text that only contains Latin letters.

LINE_BREAKS

QRegularExpression Qx::RegularExpression::LINE_BREAKS = QRegularExpression(u"[\\r\\n\\v]"_s)

inlinestatic

Matches any line break character.

LONG_SEMANTIC_VERSION

QRegularExpression Qx::RegularExpression::LONG_SEMANTIC_VERSION

inlinestatic

Initial value:

= QRegularExpression(
                u"(?P<major>0|[1-9]\\d*)"_s
                u"\\."_s
                u"(?P<minor>0|[1-9]\\d*)"_s
                u"\\."_s
                u"(?P<patch>0|[1-9]\\d*)"_s
                u"\\."_s
                u"(?P<revision>0|[1-9]\\d*)"_s
                u"(?:-(?P<prerelease>(?:0|[1-9]\\d*|\\d*[a-zA-Z-][0-9a-zA-Z-]*)(?:\\.(?:0|[1-9]\\d*|\\d*[a-zA-Z-][0-9a-zA-Z-]*))*))?"_s
                u"(?:\\+(?P<buildmetadata>[0-9a-zA-Z-]+(?:\\.[0-9a-zA-Z-]+)*))?"_s)

Same as SEMANTIC_VERSION except that 4 digits are expected instead of 3, with the fourth digit corresponding to the additional capture group 'revision'.

NUMBERS_ONLY

QRegularExpression Qx::RegularExpression::NUMBERS_ONLY = QRegularExpression(u"^[0-9]*$"_s, QRegularExpression::CaseInsensitiveOption)

inlinestatic

Matches text that only contains numeric characters.

SEMANTIC_VERSION

QRegularExpression Qx::RegularExpression::SEMANTIC_VERSION

inlinestatic

Initial value:

= QRegularExpression(
                u"(?P<major>0|[1-9]\\d*)"_s
                u"\\."_s
                u"(?P<minor>0|[1-9]\\d*)"_s
                u"\\."_s
                u"(?P<patch>0|[1-9]\\d*)"_s
                u"(?:-(?P<prerelease>(?:0|[1-9]\\d*|\\d*[a-zA-Z-][0-9a-zA-Z-]*)(?:\\.(?:0|[1-9]\\d*|\\d*[a-zA-Z-][0-9a-zA-Z-]*))*))?"_s
        u"(?:\\+(?P<buildmetadata>[0-9a-zA-Z-]+(?:\\.[0-9a-zA-Z-]+)*))?"_s)

Matches text that denotes a semantic version in accordance with the Semantic Version 2.0.0 specification.

The resulting match is valid for VersionNumber::fromString().

Provides the following capture groups:

• major
• minor
• patch
• prerelease
• buildmetadata

Note

Unlike the officially recommended regular expression, this one does not use ^ or $ so that the semantic version section of a larger string may be matched.

VersionNumber.

WHITESPACE

QRegularExpression Qx::RegularExpression::WHITESPACE = QRegularExpression(u"[\\f\\n\\r\\t\\v\x20\xA0\x00A0\u2028\u2029]"_s)

inlinestatic

Matches any whitespace character. Specifically:

• \f
• \n
• \r
• \t
• \v
• \x20
• \xA0
• \u00A0
• \u2028
• \u2029
