CoreWindowResizeManager 类

定义

命名空间:

Windows.UI.Core

定义用于管理 CoreWindow.SizeChanged 事件的类型。 此类型由框架 (（如 XAML) 或实现自己的 IFrameWorkView 的应用）使用，以同步 shell 绘制的 placholder (（如初始屏幕) ）与应用第一个绘制帧之间的切换，以便在从一个帧到另一个帧的转换中没有间隙。 如果应用未实现 IFrameWorkView 本身，则不应参与此同步，因为框架会为你执行此同步。

注解

触发 CoreWindow.SizeChanged 时，调用静态 CoreWindowResizeManager.GetForCurrentView 方法以获取当前 CoreWindow 的此类型的实例。

if (m_windowSizeChangeInProgress)
{
    // A window size change has been initiated and the app has just completed presenting
    // the first frame with the new size. Notify the resize manager so that we can abbreviate
    // any resize animation and prevent unnecessary delays.
    Windows::UI::Core::CoreWindowResizeManager::GetForCurrentView().NotifyLayoutCompleted();
    m_windowSizeChangeInProgress = false;
}

if (m_windowSizeChangeInProgress)
{
 // A window size change has been initiated and the app has just completed presenting
 // the first frame with the new size. Notify the resize manager so we can abbreviate
 // any resize animation and prevent unnecessary delays.
 CoreWindowResizeManager::GetForCurrentView()->NotifyLayoutCompleted();
 m_windowSizeChangeInProgress = false;
}

属性

ShouldWaitForLayoutCompletion

获取或设置调用方是否应等待新布局完成。

方法

GetForCurrentView()	获取正在运行的应用当前 CoreWindow 的 CoreWindowResizeManager 实例。
NotifyLayoutCompleted()	通知父 CoreWindow 对象新布局已完成。
