Class Details

class Gtk.StringFilter(**kwargs)

Bases:

Gtk.Filter

Abstract:

No

Structure:

Gtk.StringFilterClass

Determines whether to include items by comparing strings to a fixed search term.

The strings are obtained from the items by evaluating an expression set with [method`Gtk`.StringFilter.set_expression], and they are compared against a search term set with [method`Gtk`.StringFilter.set_search].

GtkStringFilter has several different modes of comparison - it can match the whole string, just a prefix, or any substring. Use [method`Gtk`.StringFilter.set_match_mode] choose a mode.

It is also possible to make case-insensitive comparisons, with [method`Gtk`.StringFilter.set_ignore_case].

classmethod new(expression)

Parameters:

expression (Gtk.Expression or None) – the expression to evaluate

Returns:

a new GtkStringFilter

Return type:

Gtk.StringFilter

Creates a new string filter.

You will want to set up the filter by providing a string to search for and by providing a property to look up on the item.

get_expression()

Returns:

the expression

Return type:

Gtk.Expression or None

Gets the expression that the string filter uses to obtain strings from items.

get_ignore_case()

Returns:

true if the filter ignores case

Return type:

bool

Returns whether the filter ignores case differences.

get_match_mode()

Returns:

the match mode of the filter

Return type:

Gtk.StringFilterMatchMode

Returns the match mode that the filter is using.

get_search()

Returns:

the search term

Return type:

str or None

Gets the search term.

set_expression(expression)

Parameters:

expression (Gtk.Expression or None) – the expression

Sets the expression that the string filter uses to obtain strings from items.

The expression must have a value type of G_TYPE_STRING.

set_ignore_case(ignore_case)

Parameters:

ignore_case (bool) – true to ignore case

Sets whether the filter ignores case differences.

set_match_mode(mode)

Parameters:

mode (Gtk.StringFilterMatchMode) – the new match mode

Sets the match mode for the filter.

set_search(search)

Parameters:

search (str or None) – the string to search for

Sets the string to search for.
