Struct glib::BindingGroup

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`

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 ObjectExt::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
