I'd like to embed another application window[*] in my application.
I found this code


and it works. Since my application should run under windows that should 
be enough, but I prefer to do my testing under Linux, so I'd like a 
solution for the qt5 widgetset.

I tried this code

procedure TForm1.Button1Click(Sender: TObject);
var kk:QWindowH;
   cc: QWidgetH;

and, while the other application window disappears, I don't see it in my 
form (it's still running though).

I tried to find some clues in the mplayer control but it doesn't work 
with qt (I tried to adapt it with no success), besides it just instructs 
mplayer to embed itself in a control.

[*] actually I need to embed a browser, but none of the alternatives in 
https://wiki.freepascal.org/Webbrowser work:

- turbopower is too limited
- I didn't try qtWebkit but it seems qt only
- geckoport has been discontinued
- fpCEF3 is old and couldn't make it work[**]
- CEF4Delphi is windows only at the moment

but playing with userChrome.css I could embed firefox as an external
