Methods

BindCommandToObject(ICommand?, object?, IObservable<object?>)

Bind an ICommand to a UI object, in the "default" way. The meaning of this is dependent on the implementation. Implement this if you have a new type of UI control that doesn't have Command/CommandParameter like WPF or has a non-standard event name for "Invoke".

public IDisposable? BindCommandToObject(ICommand? command, object? target, IObservable<object?> commandParameter)

Parameters

command ICommand

The command to bind.

target object

The target object, usually a UI control of some kind.

commandParameter IObservable<object>

An IObservable source whose latest value will be passed as the command parameter to the command. Hosts will always pass a valid IObservable, but this may be Observable.Empty.

Returns

IDisposable

An IDisposable which will disconnect the binding when disposed.

BindCommandToObject<TEventArgs>(ICommand?, object?, IObservable<object?>, string)

Bind an ICommand to a UI object to a specific event. This event may be a standard .NET event, or it could be an event derived in another manner (i.e. in MonoTouch).

public IDisposable BindCommandToObject<TEventArgs>(ICommand? command, object? target, IObservable<object?> commandParameter, string eventName) where TEventArgs : EventArgs

Parameters

command ICommand

The command to bind.

target object

The target object, usually a UI control of some kind.

commandParameter IObservable<object>

An IObservable source whose latest value will be passed as the command parameter to the command. Hosts will always pass a valid IObservable, but this may be Observable.Empty.

eventName string

The event to bind to.

Returns

IDisposable

An IDisposable which will disconnect the binding when disposed.

Type Parameters

TEventArgs

The event argument type.

ForEvent(ICommand?, object?, IObservable<object?>, string, PropertyInfo)

Creates a commands binding from event and a property.

protected static IDisposable ForEvent(ICommand? command, object? target, IObservable<object?> commandParameter, string eventName, PropertyInfo enabledProperty)

Parameters

command ICommand

Command.

target object

Target.

commandParameter IObservable<object>

Command parameter.

eventName string

Event name.

enabledProperty PropertyInfo

Enabled property name.

Returns

IDisposable

The binding from event.

ForTargetAction(ICommand?, object?, IObservable<object?>, PropertyInfo)

Creates a commands binding from event and a property.

protected static IDisposable ForTargetAction(ICommand? command, object? target, IObservable<object?> commandParameter, PropertyInfo enabledProperty)

Parameters

command ICommand

The command.

target object

The target object.

commandParameter IObservable<object>

The command parameter.

enabledProperty PropertyInfo

The enabled property.

Returns

IDisposable

Returns a disposable.

GetAffinityForObject(Type, bool)

Returns a positive integer when this class supports BindCommandToObject for this particular Type. If the method isn't supported at all, return a non-positive integer. When multiple implementations return a positive value, the host will use the one which returns the highest value. When in doubt, return '2' or '0'.

public int GetAffinityForObject(Type type, bool hasEventTarget)

Parameters

type Type

The type to query for.

hasEventTarget bool

If true, the host intends to use a custom event target.

Returns

int

A positive integer if BCTO is supported, zero or a negative value otherwise.

Register(Type, int, Func<ICommand?, object?, IObservable<object?>, IDisposable>)

Registers an observable factory for the specified type and property.

protected void Register(Type type, int affinity, Func<ICommand?, object?, IObservable<object?>, IDisposable> createBinding)

Parameters

type Type

Type.

affinity int

The affinity for the type.

createBinding Func<ICommand, object, IObservable<object>, IDisposable>

Creates the binding.
