Struct gtk4::StringSorter
source · #[repr(transparent)]pub struct StringSorter { /* private fields */ }
Expand description
StringSorter
is a Sorter
that compares strings.
It does the comparison in a linguistically correct way using the current locale by normalizing Unicode strings and possibly case-folding them before performing the comparison.
To obtain the strings to compare, this sorter evaluates a
Expression
.
Properties
collation
The collation method to use for sorting.
The GTK_COLLATION_NONE
value is useful when the expression already
returns collation keys, or strings that need to be compared byte-by-byte.
The default value, GTK_COLLATION_UNICODE
, compares strings according
to the Unicode collation algorithm.
Readable | Writeable
expression
The expression to evaluate on item to get a string to compare with.
Readable | Writeable
ignore-case
If sorting is case sensitive.

Implementations§
source§impl StringSorter
impl StringSorter
sourcepub fn new(expression: Option<impl AsRef<Expression>>) -> StringSorter
pub fn new(expression: Option<impl AsRef<Expression>>) -> StringSorter
Creates a new string sorter that compares items using the given @expression.
Unless an expression is set on it, this sorter will always compare items as invalid.
expression
The expression to evaluate
Returns
a new StringSorter
sourcepub fn builder() -> StringSorterBuilder
pub fn builder() -> StringSorterBuilder
Creates a new builder-pattern struct instance to construct StringSorter
objects.
This method returns an instance of StringSorterBuilder
which can be used to create StringSorter
objects.

pub fn expression(&self) -> Option<Expression>
sourcepub fn ignores_case(&self) -> bool
pub fn ignores_case(&self) -> bool
sourcepub fn set_collation(&self, collation: Collation)
Available on crate feature v4_10
only.

v4_10
only.sourcepub fn set_expression(&self, expression: Option<impl AsRef<Expression>>)
pub fn set_expression(&self, expression: Option<impl AsRef<Expression>>)
Sets the expression that is evaluated to obtain strings from items.
The expression must have the type G_TYPE_STRING
.
