Member Type Documentation

enum QIfFilterTerm::Operator

Constant	Value	Description
`QIfFilterTerm::Equals`	`0`	Tests whether the value from the identifier is the equal to the passed value. In case of a string the comparison is case-senstitive.
`QIfFilterTerm::EqualsCaseInsensitive`	`1`	Tests whether the value from the identifier is the equal to the passed value, but the comparison is done case-insensitive.
`QIfFilterTerm::Unequals`	`2`	Tests whether the value from the identifier is the unequal to the passed value. In case of a string the comparison is case-senstitive.
`QIfFilterTerm::GreaterThan`	`3`	Tests whether the value from the identifier is greater than the passed value. This does only work for numbers.
`QIfFilterTerm::GreaterEquals`	`4`	Tests whether the value from the identifier is greater than or equal to the passed value. This does only work for numbers.
`QIfFilterTerm::LowerThan`	`5`	Tests whether the value from the identifier is lower than the passed value. This does only work for numbers.
`QIfFilterTerm::LowerEquals`	`6`	Tests whether the value from the identifier is lower than or equal to the passed value. This does only work for numbers.
