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

[Windows.Foundation.Metadata.ContractVersion(typeof(Windows.Foundation.UniversalApiContract), 65536)]
[Windows.Foundation.Metadata.MarshalingBehavior(Windows.Foundation.Metadata.MarshalingType.Standard)]
public sealed class WindowSizeChangedEventArgs

示例

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

// Size changed data in WindowSizeChangedEventArgs.
void OnWindowSizeChanged(Windows::UI::Core::CoreWindow const& /* sender */, Windows::UI::Core::WindowSizeChangedEventArgs const& /* args */) {}

// returning window size change events data through WindowSizeChangedEventArgs
void MyCoreWindowEvents::SetWindow( // implementation called by CoreApplication::Run(), provided for context
    _In_ CoreWindow^ window
    )
{
    // ...
    window->SizeChanged +=
        ref new TypedEventHandler<CoreWindow^, WindowSizeChangedEventArgs^>(this, &CoreWindowEvents::OnWindowSizeChanged)
    // ...
}

注解

此对象由为 CoreWindow.SizeChanged 事件注册的委托返回。

注意

此类不是敏捷类，这意味着需要考虑其线程模型和封送处理行为。 有关详细信息，请参阅 线程处理和封送处理 (C++/CX) 。
