Button in the title

Hi all. Anyone has idea - how I can do the following

I found out that it's called DWM. But I don't know how to do this kind of stuff.

Hi and welcome to devnet,

Do you mean this ?

@SGaist I'm sorry. I have updated my link, so now you can see what I need. Thanks.

hi
That you cannot do. The windows decorations are drawn by the OS and
Qt cannot custom draw it. ( as far as i know)

You can remove the caption and draw all yourself and must also handle drag in caption and
all other windows function so not a small task.

As @mrjj wrote, that's outside the scope of Qt, you'll have to check with Windows native API in order to do something like that.
