How to add frameless display to Windows taskbar?

Hello,
when creating a frameless display (with the ALLEGRO_NOFRAME option), the window is not displayed in the Windows taskbar anymore. Is there a way to keep/add the window to the taskbar?

It's a known bug, https://github.com/liballeg/allegro5/issues/795. It should be easy to fix, but I just tried for a few minutes and failed. As the bug describes, alt-tabbing still works, so it'll appear after an alt-tab.

Thanks for your reply.
I already figured out, that Alt+Tab brings the window to the taskbar, too.
If anyone might know a workaround to add to my code, which would bring the window to the taskbar immediately (without having to press Alt+Tab first), I would really appreciate that.

It should be as simple as removing the parent of the HWND that allegro is using. But that might cause other problems.

As stated here :

Managing Taskbar Buttons

The Shell creates a button on the taskbar whenever an application creates a window that isn't owned. To ensure that the window button is placed on the taskbar, create an unowned window with the WS_EX_APPWINDOW extended style. To prevent the window button from being placed on the taskbar, create the unowned window with the WS_EX_TOOLWINDOW extended style. As an alternative, you can create a hidden window and make this hidden window the owner of your visible window.
