WinUI3:What is the right way to create and initialize UIElement Programatically with C++/Winrt

Question

Hi,

I'm trying to bring up the WinUI3 window programmatically with c++/winrt. To bring up the first window, I created a Window variable and activated it, Like this

using namespace winrt::Microsoft::UI::Xaml::Controls;  

Window SampleWindow;  
SampleWindow.Activate();  

By this, I was able to bring up a window, my concern here is, is this the correct way to initialize a window and activate it[Programatically]? I could not find any official documentation for Initializing UIElement programmatically with C++. So is this the right way to do it?

Hello @21939029 ，
Welcome to Microsoft Q&A!

Your code is ok.

You can refer to the example of Window Class, and the startup method of MainWindow.

winrt::Microsoft::UI::Xaml::Window window{ nullptr };  
  
void App::OnLaunched(LaunchActivatedEventArgs const&)  
{  
    window = make<MainWindow>();  
    window.Activate();  
}  

Thank you.
Junjie
