Struct gtk4::NumericSorter
source · #[repr(transparent)]pub struct NumericSorter { /* private fields */ }
Expand description
NumericSorter
is a Sorter
that compares numbers.
To obtain the numbers to compare, this sorter evaluates a
Expression
.
Properties
expression
The expression to evaluate on items to get a number to compare with.
Readable | Writeable
sort-order
Whether the sorter will sort smaller numbers first.

Implementations§
source§impl NumericSorter
impl NumericSorter
sourcepub fn new(expression: Option<impl AsRef<Expression>>) -> NumericSorter
pub fn new(expression: Option<impl AsRef<Expression>>) -> NumericSorter
Creates a new numeric sorter using the given @expression.
Smaller numbers will be sorted first. You can call
set_sort_order()
to change this.
expression
The expression to evaluate
Returns
a new NumericSorter
sourcepub fn builder() -> NumericSorterBuilder
pub fn builder() -> NumericSorterBuilder
Creates a new builder-pattern struct instance to construct NumericSorter
objects.
This method returns an instance of NumericSorterBuilder
which can be used to create NumericSorter
objects.
sourcepub fn expression(&self) -> Option<Expression>
pub fn expression(&self) -> Option<Expression>
sourcepub fn sort_order(&self) -> SortType
pub fn sort_order(&self) -> SortType
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 numbers from items.
Unless an expression is set on @self, the sorter will always compare items as invalid.
The expression must have a return type that can be compared
numerically, such as G_TYPE_INT
or G_TYPE_DOUBLE
.
expression
sourcepub fn set_sort_order(&self, sort_order: SortType)
pub fn set_sort_order(&self, sort_order: SortType)
Sets whether to sort smaller numbers before larger ones.
sort_order
whether to sort smaller numbers first
pub fn connect_expression_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId
pub fn connect_sort_order_notify<F: Fn(&Self) + 'static>( &self, f: F ) -> SignalHandlerId
