[UWP]从不同的线程获取ApplicationView /从不同的线程切换到全屏; [英] [UWP] Get ApplicationView from different thread / switching to fullscreen from different thread;

问题描述

你好，



有没有办法从主应用程序线程以外的地方访问ApllicationView？  ; $


Windows :: UI :: ViewManagement :: ApplicationView :: GetForCurrentView（）;总是导致"找不到元素"错误，即使在"alt-enter"时也是如此。在应用程序主线程中定义的全屏切换功能完美无缺。

解决方案

CoreApplicationView提供的属性可以返回应用程序的MainView或返回所有应用程序视图的集合。

获得View后即可使用其Dispatcher属性来编组一个函数，以便在视图的调度程序线程上运行。

Hallo,

Is there any way to get to the ApllicationView from other than the main app thread? 

Windows::UI::ViewManagement::ApplicationView::GetForCurrentView(); always causes "element not found" error, even when the "alt-enter" fullscreen switch function defined in the main thread of the app works perfect.

Best, Radek

解决方案

The CoreApplicationView provides properties to return the app's MainView or to return a collection of all of the app's Views.

Once you have the View you can use its Dispatcher property to marshal a function to run on the view's dispatcher thread.
