Member Type Documentation

enum QIfFilterTerm::Operator

ConstantValueDescription
QIfFilterTerm::Equals0Tests whether the value from the identifier is the equal to the passed value. In case of a string the comparison is case-senstitive.
QIfFilterTerm::EqualsCaseInsensitive1Tests whether the value from the identifier is the equal to the passed value, but the comparison is done case-insensitive.
QIfFilterTerm::Unequals2Tests whether the value from the identifier is the unequal to the passed value. In case of a string the comparison is case-senstitive.
QIfFilterTerm::GreaterThan3Tests whether the value from the identifier is greater than the passed value. This does only work for numbers.
QIfFilterTerm::GreaterEquals4Tests whether the value from the identifier is greater than or equal to the passed value. This does only work for numbers.
QIfFilterTerm::LowerThan5Tests whether the value from the identifier is lower than the passed value. This does only work for numbers.
QIfFilterTerm::LowerEquals6Tests whether the value from the identifier is lower than or equal to the passed value. This does only work for numbers.
