How does Sierra Chart use WinUI?

Hello,

I would like to know how Sierra Chart works with WinUI.

I know that the appearance of certain elements, such as the main menu bar, scrollbars, and some menus, is controlled via WinUI. However, when I switch to dark mode in Windows, these elements remain light, whereas in other applications they turn dark.

I’m curious to know why this is the case. Thank you.

We were not sure what this is. And we looked it up. Sierra Chart does not use WinUI.

If Sierra Chart doesn't use WinUI 3, how are the elements pointed to by my arrows in the screenshot created? It doesn't appear that the Win32 API is being used for this.

I'm asking because I'm trying to customize the platform's colors, but I can't achieve everything I want by editing the Windows registry.

For example, if I change the MenuBar's color, nothing happens. Other elements can be customized.
