StringSorter

class StringSorter(**properties: Any)

Superclasses: Sorter, Object

GtkStringSorter is a GtkSorter 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.

Constructors

class StringSorter

classmethod new(expression: Expression | None = None) → 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.

Parameters:: expression – The expression to evaluate

Methods

class StringSorter

get_collation() → Collation: Gets which collation method the sorter uses.

Added in version 4.10.

get_expression() → Expression | None: Gets the expression that is evaluated to obtain strings from items.

get_ignore_case() → bool: Gets whether the sorter ignores case differences.

set_collation(collation: Collation) → None

Sets the collation method to use for sorting.

Added in version 4.10.

Parameters:: collation – the collation method

set_expression(expression: Expression | None = None) → None

Sets the expression that is evaluated to obtain strings from items.

The expression must have the type str.

Parameters:: expression – a GtkExpression

set_ignore_case(ignore_case: bool) → None

Sets whether the sorter will ignore case differences.

Parameters:: ignore_case – True to ignore case differences

Properties

class StringSorter

props.collation: 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.

Added in version 4.10.

props.expression: Expression: The expression to evaluate on item to get a string to compare with.

props.ignore_case: bool: If sorting is case sensitive.
