Exemples

Ici, nous créons un DispatcherQueue sur un thread d’arrière-plan dédié, puis initialisons un objet RadialControllerInpdependentInputSource, qui est créé sur le thread d’arrière-plan.

public void CreateCoreIndependentInputSourceSample() 
{ 
    // Create a new thread, initialize DispatcherQueueController, 
    // and run a DispatcherQueue event loop on it. 
    _queueController =  
        DispatcherQueueController.CreateOnDedicatedThread(); 
    _queue = _queueController.DispatcherQueue;  

    // This is the first TryEnqueue() after creating the DispatcherQueue 
    // callback is guaranteed to be invoked first despite priority on the 
    // newly created thread. 
    bool isQueued = _queue.TryEnqueue( () => 
        {
            // The RadialControllerIndependentInputSource will raise events 
            // on the thread that created it.  
            radialInput = 
                RadialControllerIndependentInputSource.CreateForView(view); 
            radialInput.Controller.ButtonClicked += OnButtonClicked; 
            radialInput.Controller.ButtonHeld += OnButtonHeld; 
            radialInput.Controller.ButtonPressed += OnButtonPressed;  

            // Add RadialControllerMenuItems for this controller. 
            AddMenuItems(radialInput.Controller) 
        });         

    if (!isQueued) 
    { 
        // throw exception as this callback is enqueued. 
    } 

    // Enqueuing future tasks to this thread can be done using the DispatcherQueue 
    // property in RadialControllerIndependentInputSource.
    bool isTaskQueued = radialInput.DispatcherQueue.TryEnqueue( () => 
        { 
            // TODO. 
        }); 
}  

private DispatcherQueueController _queueController; 
private DispatcherQueue _queue; 
private RadialControllerIndependentInputSource radialInput; 

Remarques

Appelez DispatcherQueueController.CreateOnDedicatedThread pour créer le DispatcherQueue sur le thread d’arrière-plan où radialControllerIndependentInputSource est instancié. Accédez à ce DispatcherQueue à l’aide de la propriété RadialControllerIndependentInputSource.DispatcherQueue .
