Detailed Description

Sort by comparing strings.

Gtk::StringSorter is a Gtk::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 Gtk::Expression.

◆ get_collation()

Collation Gtk::StringSorter::get_collation ( ) const

Gets which collation method the sorter uses.

Since gtkmm 4.10:

Returns: The collation method.

◆ get_expression() [1/2]

Glib::RefPtr<Expression<Glib::ustring> > Gtk::StringSorter::get_expression ( )

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

Returns: A Gtk::Expression.

◆ get_expression() [2/2]

Glib::RefPtr<const Expression<Glib::ustring> > Gtk::StringSorter::get_expression ( ) const

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

Returns: A Gtk::Expression.

◆ get_ignore_case()

bool Gtk::StringSorter::get_ignore_case ( ) const

Gets whether the sorter ignores case differences.

Returns: true if self is ignoring case differences.

◆ get_type()

static

Get the GType for this class, for use with the underlying GObject type system.

◆ gobj() [1/2]

GtkStringSorter* Gtk::StringSorter::gobj ( )

inline

Provides access to the underlying C GObject.

◆ gobj() [2/2]

const GtkStringSorter* Gtk::StringSorter::gobj ( ) const

inline

Provides access to the underlying C GObject.

◆ gobj_copy()

GtkStringSorter* Gtk::StringSorter::gobj_copy ( )

◆ operator=()

noexcept

◆ property_collation() [1/2]

Glib::PropertyProxy< Collation > Gtk::StringSorter::property_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.

Since gtkmm 4.10:

Default value: Gtk::Collation::UNICODE

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_collation() [2/2]

Glib::PropertyProxy_ReadOnly< Collation > Gtk::StringSorter::property_collation ( ) const

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.

Since gtkmm 4.10:

Default value: Gtk::Collation::UNICODE

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_expression() [1/2]

Glib::PropertyProxy< Glib::RefPtr<Expression<Glib::ustring> > > Gtk::StringSorter::property_expression ( )

The expression to evaluate on item to get a string to compare with.

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_expression() [2/2]

Glib::PropertyProxy_ReadOnly< Glib::RefPtr<Expression<Glib::ustring> > > Gtk::StringSorter::property_expression ( ) const

The expression to evaluate on item to get a string to compare with.

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ property_ignore_case() [1/2]

Glib::PropertyProxy< bool > Gtk::StringSorter::property_ignore_case ( )

If sorting is case sensitive.

Default value: true

Returns: A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

◆ property_ignore_case() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::StringSorter::property_ignore_case ( ) const

If sorting is case sensitive.

Default value: true

Returns: A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

◆ set_collation()

void Gtk::StringSorter::set_collation ( Collation collation )

Sets the collation method to use for sorting.

Since gtkmm 4.10:

Parameters

collation The collation method.

◆ set_expression()

void Gtk::StringSorter::set_expression ( const Glib::RefPtr< Expression< Glib::ustring >> & expression )

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

The expression must have the type G_TYPE_STRING.

Parameters

expression A Gtk::Expression.

◆ set_ignore_case()

void Gtk::StringSorter::set_ignore_case ( bool ignore_case = true )

Sets whether the sorter will ignore case differences.

Parameters

ignore_case true to ignore case differences.

◆ wrap()

Glib::RefPtr< Gtk::StringSorter > wrap	(	GtkStringSorter *	object,
		bool	take_copy = `false`
	)

A Glib::wrap() method for this object.

Parameters

object	The C instance.
take_copy	False if the result should take ownership of the C instance. True if it should take a new copy or ref.

Returns: A C++ instance that wraps this C instance.
