Struct gtk4::CustomFilter

#[repr(transparent)]
pub struct CustomFilter { /* private fields */ }

CustomFilter determines whether to include items with a callback.

Implements

FilterExt, glib::ObjectExt

Implementations

impl CustomFilter

pub fn new<F>(filter_func: F) -> Selfwhere F: Fn(&Object) -> bool + 'static,

Creates a new filter using the given @match_func to filter items.

If @match_func is None, the filter matches all items.

If the filter func changes its filtering behavior, gtk_filter_changed() needs to be called.

match_func

function to filter items

Returns

a new CustomFilter

pub fn set_filter_func<F>(&self, filter_func: F)where F: Fn(&Object) -> bool + 'static,

Sets the function used for filtering items.

If @match_func is None, the filter matches all items.

If the filter func changes its filtering behavior, gtk_filter_changed() needs to be called.

If a previous function was set, its @user_destroy will be called now.

match_func

function to filter items

pub fn unset_filter_func(&self)

Trait Implementations

impl Clone for CustomFilter

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CustomFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CustomFilter

fn default() -> Self

Returns the “default value” for a type.

impl Display for CustomFilter

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl HasParamSpec for CustomFilter

type ParamSpec = ParamSpecObject

type SetValue = CustomFilter

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(_: &str) -> ParamSpecObjectBuilder<'_, CustomFilter>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for CustomFilter

fn hash<H>(&self, state: &mut H)where H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CustomFilter

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Selfwhere Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for CustomFilter

type Parent = Filter

impl<OT: ObjectType> PartialEq<OT> for CustomFilter

fn eq(&self, other: &OT) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl<OT: ObjectType> PartialOrd<OT> for CustomFilter

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

This method tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

This method tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

This method tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for CustomFilter

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for CustomFilter

impl IsA<Filter> for CustomFilter
