Filter

Superclasses: Object

Filter(**properties)

Methods

class Filter

changed(change: FilterChange) → None

Notifies all users of the filter that it has changed.

This emits the changed signal. Users of the filter should then check items again via match.

Depending on the change parameter, not all items need to be changed, but only some. Refer to the FilterChange documentation for details.

This function is intended for implementers of GtkFilter subclasses and should not be called from other functions.

get_strictness() → FilterMatch

Gets the known strictness of filters.

If the strictness is not known, SOME is returned.

This value may change after emission of the changed signal.

This function is meant purely for optimization purposes, filters can choose to omit implementing it, but GtkFilterListModel uses it.

match(item: Object) → bool

Checks if the given item is matched by the filter or not.

class Filter.signals

changed(change: FilterChange) → None

Emitted whenever the filter changed.

Users of the filter should then check items again via match.

GtkFilterListModel handles this signal automatically.

Depending on the change parameter, not all items need to be checked, but only some. Refer to the FilterChange documentation for details.

class Filter

do_get_strictness() → FilterMatch

Gets the known strictness of filters.

If the strictness is not known, SOME is returned.

This value may change after emission of the changed signal.

This function is meant purely for optimization purposes, filters can choose to omit implementing it, but GtkFilterListModel uses it.

do_match(item: Object | None = None) → bool

Checks if the given item is matched by the filter or not.
