Examples

void SetWindow(CoreWindow const & window)
{
    window.PointerCursor(Windows::UI::Core::CoreCursor{ CoreCursorType::Arrow, 0 });

    window.PointerPressed({ this, &App::OnPointerPressed });
    window.PointerReleased({ this, &App::OnPointerReleased });
    window.PointerMoved({ this, &App::OnPointerMoved });
}

// Pointer event data in PointerEventArgs.
void OnPointerPressed(Windows::UI::Core::CoreWindow const& /* sender */,
    Windows::UI::Core::PointerEventArgs const& /* args */) {}

void OnPointerReleased(Windows::UI::Core::CoreWindow const& /* sender */,
    Windows::UI::Core::PointerEventArgs const& /* args */) {}

void OnPointerMoved(Windows::UI::Core::CoreWindow const& /* sender */,
    Windows::UI::Core::PointerEventArgs const& /* args */) {}

// returning pointer events data through PointerEventArgs

void MyCoreWindowEvents::SetWindow( // implementation called by CoreApplication::Run(), provided for context
    _In_ CoreWindow^ window
    )
{
    window->PointerCursor = ref new CoreCursor(CoreCursorType::Arrow, 0);

    // ...
    window->PointerPressed +=
        ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &CoreWindowEvents::OnPointerPressed);
    window->PointerReleased +=
        ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &CoreWindowEvents::OnPointerReleased);
    window->PointerMoved +=
        ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &CoreWindowEvents::OnPointerMoved);

    // ...
}

Remarks

This object is returned by a delegate registered for one of the following events:

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).

Properties

CurrentPoint	Gets the pointer data of the last pointer event.
Handled	Gets or sets whether the pointer event was handled.
KeyModifiers	Gets the keyboard key or keys used to modify the pointer input, such as the "Ctrl" key when pressed in conjunction with another key, as in Ctrl+C.

Methods

GetIntermediatePoints()

Retrieves the pointer data for up to the last 64 pointer locations since the last pointer event.
