Transparent window

Hi, I am trying to make a transparent window, so the objects in the scene will display on top of windows. Take a look at this:
This is how it looks if I use that code:

Anyone know how to fix this? Thankyou

This works:

    const auto hwnd = GetActiveWindow();

    if (hwnd)
        SetWindowLongPtr(hwnd, GWL_STYLE, WS_VISIBLE);

        RECT rect;
        GetWindowRect(hwnd, &rect);
        SetWindowPos(hwnd, HWND_TOPMOST, rect.left,, rect.right - rect.left, rect.bottom -, SWP_SHOWWINDOW);

        const MARGINS margins{ -1 };
        DwmExtendFrameIntoClientArea(hwnd, &margins);

Remove WS_EX_LAYERED if you don’t want click-through

Thankyou very much!

Can you guide a bit upon where this should be done? Is it in unreal ? if yes then which file or classes needed to be modified ?

Hi, any idea why this works on windows 8 but doesn’t work on windows 11 ? I haven’t tried on windows 10.

I want to test it in Windows 10 but can’t figure out which class should I manipulate. Is it the regular SWindow in Slate? Something else?

Thanks for any clues on the implementation!
