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->PointerReleased +=
ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &CoreWindowEvents::OnPointerReleased);
window->PointerMoved +=
ref new TypedEventHandler<CoreWindow^, PointerEventArgs^>(this, &CoreWindowEvents::OnPointerMoved);
// ...
}
備註
此物件是由針對下列其中一個事件註冊的委派所傳回:
- CoreWindow.PointerCaptureLost
- CoreWindow.PointerEntered
- CoreWindow.PointerExited
- CoreWindow.PointerMoved
- CoreWindow.PointerPressed
- CoreWindow.PointerReleased
- CoreWindow.PointerWheelChanged
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。 |
