QString Utils::qtcEnvironmentVariable(const QString &key)

Returns the value of key in Qt Creator's modified system environment.

See also Utils::Environment::systemEnvironment and qEnvironmentVariable.

QString Utils::qtcEnvironmentVariable(const QString &key, const QString &defaultValue)

Returns the value of key in Qt Creator's modified system environment if it is set, or otherwise defaultValue.

See also Utils::Environment::systemEnvironment and qEnvironmentVariable.

int Utils::qtcEnvironmentVariableIntValue(const QString &key, bool *ok = nullptr)

Returns the value of key in Qt Creator's modified system environment, converted to an int. If ok is not null, sets *ok to true or false depending on the success of the conversion

See also Utils::Environment::systemEnvironment and qEnvironmentVariableIntValue.

bool Utils::qtcEnvironmentVariableIsEmpty(const QString &key)

Returns if the environment variable key is not set or empty in Qt Creator's modified system environment.

See also Utils::Environment::systemEnvironment and qEnvironmentVariableIsEmpty.

bool Utils::qtcEnvironmentVariableIsSet(const QString &key)

Returns if the environment variable key is set Qt Creator's modified system environment.

See also Utils::Environment::systemEnvironment and qEnvironmentVariableIsSet.

QString Utils::trim(const QString &string, QChar ch)

Returns a copy of string that has ch characters removed from the start and the end.

QString Utils::trimBack(const QString &string, QChar ch)

Returns a copy of string that has ch characters removed from the end.
