I'm trying to create a Windows Application via the Windows Api (Win32). I want to remove the Windows Titlebar, but keep other Decorations (Border, Shadow, Rounded Corners). I have tried quite a few combinations of window styles, but cant get it to work.
[https://learn.microsoft.com/en-us/windows/win32/winmsg/window-styles
[https://learn.microsoft.com/en-us/windows/win32/winmsg/extended-window-styles
I also tried DwmExtendFrameIntoClientArea, but it made no difference.
This should be possible, because I can do it with a framework like Tauri ([https://tauri.app/). (by disabling decorations and using the window-border plugin). And Tauri is also just calling the Win32 Api in the background.

2023-01-21T16:23:53.9366667+00:00 DwmExtendFrameIntoClientArea is the usual way (Custom Window Frame Using DWM)
But Rounded Corners are for Windows 11 (Apply rounded corners in desktop apps for Windows 11)
(I cannot test (Windows 10 only where I can customize borders))
