Struct TemplateBindingExpression 

pub struct TemplateBindingExpression { /* private fields */ }

A binding expression that reads a property of the templated parent of its target.

Implementations

impl TemplateBindingExpression

pub fn new( property: Option<&'static FerroProperty>, converter: Option<Rc<dyn IValueConverter>>, converter_culture: Option<CultureInfo>, converter_parameter: Option<BoxedValue>, mode: BindingMode, ) -> Rc<Self>

Trait Implementations

impl BindingExpressionBase for TemplateBindingExpression

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 Drop for TemplateBindingExpression

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl IDisposable for TemplateBindingExpression

fn dispose(&self)

impl UntypedBindingExpression for TemplateBindingExpression

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.
