Implementations

impl<'a, 'f, 't> BindingBuilder<'a, 'f, 't>

fn new( source: &'a impl ObjectType, source_property: &'a str, target: &'a impl ObjectType, target_property: &'a str, ) -> Self

pub fn transform_from_with_values<F: Fn(&Binding, &Value) -> Option<Value> + Send + Sync + 'static>( self, func: F, ) -> Self

Transform changed property values from the target object to the source object with the given closure.

This function operates on glib::Values. See Self::transform_from for a version which operates on concrete argument and return types.

pub fn transform_from<S: FromValue<'f>, T: Into<Value>, F: Fn(&'f Binding, S) -> Option<T> + Send + Sync + 'static>( self, func: F, ) -> Self

Transform changed property values from the target object to the source object with the given closure.

This function operates on concrete argument and return types. See Self::transform_from_with_values for a version which operates on glib::Values.

pub fn transform_to_with_values<F: Fn(&Binding, &Value) -> Option<Value> + Send + Sync + 'static>( self, func: F, ) -> Self

Transform changed property values from the source object to the target object with the given closure.

This function operates on glib::Values. See Self::transform_to for a version which operates on concrete argument and return types.

pub fn transform_to<S: FromValue<'t>, T: Into<Value>, F: Fn(&'t Binding, S) -> Option<T> + Send + Sync + 'static>( self, func: F, ) -> Self

Transform changed property values from the source object to the target object with the given closure.

This function operates on concrete argument and return types. See Self::transform_to_with_values for a version which operates on glib::Values.

pub fn flags(self, flags: BindingFlags) -> Self

Bind the properties with the given flags.

pub fn bidirectional(self) -> Self

Set the binding flags to BIDIRECTIONAL.

pub fn sync_create(self) -> Self

Set the binding flags to SYNC_CREATE.

pub fn invert_boolean(self) -> Self

Set the binding flags to INVERT_BOOLEAN.

pub fn build(self) -> Binding

Establish the property binding.

Panics

This panics if the provided properties do not exist.

Trait Implementations

impl<'a, 'f, 't> Debug for BindingBuilder<'a, 'f, 't>

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

Formats the value using the given formatter.
