Struct CreatesCommandBindingViaEvent 

pub struct CreatesCommandBindingViaEvent<C> { /* private fields */ }

Binds a command to an event of a control of type C (CreatesCommandBindingViaEvent): executed with the latest command parameter each time the event is raised, if the command can execute with it.

The events are registered by name (with_event). Without an event name, the command binds to the first of DEFAULT_COMMAND_EVENTS that is registered, then to the first registered event.

The affinity is BindingAffinity::EXPLICIT for a named event and BindingAffinity::DEFAULT_EVENT for a default event, for a control of type C only.

Implementations

impl<C: 'static> CreatesCommandBindingViaEvent<C>

pub fn new() -> Self

A binder with no event.

pub fn with_event<A: ?Sized + 'static>( self, name: impl Into<String>, event: fn(&C) -> &Event<A>, ) -> Self

Registers the event named name that event reads from a control.

pub fn with_event_subscription( self, name: impl Into<String>, subscription: ControlEventSubscription<C>, ) -> Self

Registers the event named name that subscription adds a handler to.

Trait Implementations

impl<C> Debug for CreatesCommandBindingViaEvent<C>

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

Formats the value using the given formatter.

impl<C: 'static> Default for CreatesCommandBindingViaEvent<C>

fn default() -> Self

Returns the “default value” for a type.

impl<C: 'static> ICreatesCommandBinding for CreatesCommandBindingViaEvent<C>

fn get_affinity_for_object( &self, target_type: TypeId, has_event_target: bool, ) -> i32

A positive number when this plugin can bind a command to an object of the type target_type, the highest number winning among the plugins; zero or less when it cannot (GetAffinityForObject<T>(bool hasEventTarget)). has_event_target says whether the caller names the event to bind to.

fn bind_command_to_object( &self, command: Option<Rc<dyn ICommand>>, target: Option<Rc<dyn Any>>, command_parameter: Rc<dyn IObservable<CommandParameter>>, ) -> Option<Rc<dyn IDisposable>>

Binds command to target through the default event of the target (Click, …), executed with the latest value of command_parameter; None when no binding was made, as for a missing command (BindCommandToObject<T>). Disposing the result unbinds the command.

fn bind_command_to_object_event( &self, command: Option<Rc<dyn ICommand>>, target: Option<Rc<dyn Any>>, command_parameter: Rc<dyn IObservable<CommandParameter>>, event_name: &str, ) -> Option<Rc<dyn IDisposable>>

Binds command to the event named event_name of target (BindCommandToObject<T, TEventArgs>(..., string eventName)).

fn bind_command_to_object_with_handlers( &self, command: Option<Rc<dyn ICommand>>, target: Option<Rc<dyn Any>>, command_parameter: Rc<dyn IObservable<CommandParameter>>, subscription: CommandEventSubscription, ) -> Option<Rc<dyn IDisposable>>

Binds command to the event that subscription adds a handler to (BindCommandToObject<T, TEventArgs>(..., addHandler, removeHandler)).
