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.

Gets which collation method the sorter uses.

Since gtkmm 4.10:
Returns
The collation method.

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 ( )

Provides access to the underlying C GObject.

◆ gobj() [2/2]

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
collationThe 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
expressionA 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_casetrue to ignore case differences.

bool  take_copy = false 
)
related

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

Parameters
