CharacterReceivedEventArgs Class

Definition

Namespace:

Windows.UI.Core

Provides the arguments returned by the event raised when a character is received by the input queue.

public ref class CharacterReceivedEventArgs sealed

/// [Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Standard)]
class CharacterReceivedEventArgs final

Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Remarks

Windows 10 Apps do not receive this event when an Input Method Editor (IME) is enabled. The Input Method Editor (IME) handles all keyboard input and sets Handled to true.

Windows Phone This API is supported in native apps only.

This object is returned by a delegate registered for the following event:

• CoreWindow.CharacterReceived

void SetWindow(CoreWindow const& window)
{
    ...
    window.CharacterReceived({this, &App::OnCharacterReceived });
}

// Character received event data in CharacterReceivedEventArgs.
void OnCharacterReceived(
    Windows::UI::Core::CoreWindow const& /* sender */,
    Windows::UI::Core::CharacterReceivedEventArgs const& /* args */)
{
}

// returning character received events data through CharacterReceivedEventArgs

void MyCoreWindowEvents::SetWindow( // implementation called by CoreApplication::Run(), provided for context
    _In_ CoreWindow^ window
    )
{
    // ...
    window->CharacterReceived +=
        ref new TypedEventHandler<CoreWindow^, CharacterReceivedEventArgs^>(this, &CoreWindowEvents::OnCharacterReceived);
    // ...
}

Note

This class is not agile, which means that you need to consider its threading model and marshaling behavior. For more info, see Threading and Marshaling (C++/CX).
