Struct glib::BindingGroup

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

Available on crate feature v2_72 only.

The BindingGroup can be used to bind multiple properties from an object collectively.

Use the various methods to bind properties from a single source object to multiple destination objects. Properties can be bound bidirectionally and are connected when the source object is set with set_source().

Implements

ObjectExt

Implementations

impl BindingGroup

pub fn new() -> BindingGroup

Creates a new BindingGroup.

Returns

a new BindingGroup

pub fn source(&self) -> Option<Object>

Gets the source object used for binding properties.

Returns

a Object or None.

pub fn set_source(&self, source: Option<&impl IsA<Object>>)

Sets source as the source object used for creating property bindings. If there is already a source object all bindings from it will be removed.

Note that all properties that have been bound must exist on source.

source

the source Object, or None to clear it

pub fn connect_source_notify<F: Fn(&Self) + Send + Sync + 'static>( &self, f: F ) -> SignalHandlerId

impl BindingGroup

pub fn bind<'a, O: ObjectType>( &'a self, source_property: &'a str, target: &'a O, target_property: &'a str ) -> BindingGroupBuilder<'a>

Creates a binding between source_property on the source object and target_property on target. Whenever the source_property is changed the target_property is updated using the same value. The binding flag BindingFlags::SYNC_CREATE is automatically specified.

See [ObjectExtManual::bind_property()][crate::prelude::ObjectExtManual::bind_property()] for more information.

source_property

the property on the source to bind

target

the target Object

target_property

the property on target to bind

flags

the flags used to create the Binding

Trait Implementations

impl Clone for BindingGroup

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 BindingGroup

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

Formats the value using the given formatter.

impl Default for BindingGroup

fn default() -> Self

Returns the “default value” for a type.

impl Display for BindingGroup

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

Formats the value using the given formatter.

impl Hash for BindingGroup

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 BindingGroup

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 BindingGroup

type Parent = Object

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

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 BindingGroup

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 BindingGroup

fn static_type() -> Type

Returns the type identifier of Self.

impl Eq for BindingGroup

impl Send for BindingGroup

impl Sync for BindingGroup
