Windows.UI.Core.CoreWindow

-description

Represents the UWP app with input events and basic user interface behaviors.

-remarks

New instances of this class are obtained by calling CoreApplication.CreateNewView and then inspecting the CoreWindow property on the returned CoreApplicationView instance. Or you can obtain existing CoreWindow instances for a running app from the CoreApplication.Views property, or by calling CoreWindow.GetForCurrentThread, as seen in the following example.

// App.cpp
...
// An implementation of IFrameworkView::Run.
void Run()
{
    CoreWindow window{ CoreWindow::GetForCurrentThread() };
    window.Activate();

    CoreDispatcher dispatcher{ window.Dispatcher() };
    dispatcher.ProcessEvents(CoreProcessEventsOption::ProcessUntilQuit);
}

// The CoreApplication::Run call indirectly calls the App::Run function above.
int __stdcall wWinMain(HINSTANCE, HINSTANCE, PWSTR, int)
{
    CoreApplication::Run(App());
}

void MyCoreWindowEvents::Run() // this is an implementation of IFrameworkView::Run() used to show context
{
    CoreWindow::GetForCurrentThread()->Activate();

    /...

    CoreWindow::GetForCurrentThread()->Dispatcher->ProcessEvents(CoreProcessEventsOption::ProcessUntilQuit);
}
