Struct MultiBindingExpression 

pub struct MultiBindingExpression { /* private fields */ }

The binding expression of a multi-binding: runs the child bindings and combines their values through a converter.

Implementations

impl MultiBindingExpression

pub fn new( priority: BindingPriority, bindings: Vec<Rc<dyn BindingBase>>, converter: Option<Rc<dyn IMultiValueConverter>>, converter_culture: Option<CultureInfo>, converter_parameter: Option<BoxedValue>, fallback_value: Option<BoxedValue>, target_null_value: Option<BoxedValue>, ) -> Rc<Self>

pub fn converter(&self) -> Option<&Rc<dyn IMultiValueConverter>>

pub fn converter_culture(&self) -> Option<&CultureInfo>

The culture in which the converter is evaluated; None for the current culture.

Trait Implementations

impl BindingExpressionBase for MultiBindingExpression

fn priority(&self) -> BindingPriority

The priority of the binding expression.

fn target_property(&self) -> Option<&'static FerroProperty>

The property that the binding expression is targeting.

fn default_priority(&self) -> BindingPriority

The preferred priority of the binding expression; the priority passed to attach may differ if the binding targets a direct property, in which case it is elevated to local value priority.

fn is_data_validation_enabled(&self) -> bool

Whether data validation is enabled for the binding expression.

fn update_source(&self)

Sends the current binding target value to the binding source property in two-way or one-way-to-source bindings. Does nothing for other modes. If the update source trigger of the binding is explicit, this must be called for changes to propagate back to the source.

fn update_target(&self)

Forces a data transfer from the binding source to the binding target.

fn as_any(&self) -> &dyn Any

impl IDisposable for MultiBindingExpression

fn dispose(&self)

impl UntypedBindingExpression for MultiBindingExpression

fn base(&self) -> &UntypedBindingExpressionBase

fn description(&self) -> String

A description of the binding expression.

fn start_core(&self)

Starts the binding expression. Do not call directly; call start.

fn stop_core(&self)

Stops the binding expression. Do not call directly; call stop.

fn write_value_to_source(&self, _value: Option<BoxedValue>) -> bool

Writes the specified value to the binding source if possible. Returns true if the value could be written.

fn should_log_error(&self) -> Option<Ref<FerroObject>>

The target to log errors against, if an error should be logged given the current state of the binding expression.

fn update_source_core(&self)

fn update_target_core(&self)

fn start(&self, produce_value: bool)

Starts the binding expression.

fn stop(&self)

Stops the binding expression.

fn dispose_expression(&self)

Terminates the binding.

fn log_error(&self, error: &str, level: LogEventLevel)

Logs a binding error against the target, if there is one.
