範例

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->PointerMoved +=
        ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &CoreWindowEvents::OnPointerMoved);

此物件是由針對下列其中一個事件註冊的委派所傳回：

注意

這個類別不是敏捷的，這表示您必須考慮其線程模型和封送處理行為。 如需詳細資訊，請參閱 線程和封送處理 (C++/CX) 。

屬性

CurrentPoint

取得最後一個指標事件的指標數據。
Handled

取得或設定是否已處理指標事件。
KeyModifiers

取得鍵盤按鍵或按鍵，用來修改指標輸入，例如當與另一個按鍵一起按下時，如 Ctrl+C 中的 “Ctrl” 鍵。

方法

GetIntermediatePoints()

擷取自最後一個指標事件以來，最多64個指標位置的指標數據。
