How to create a button on the title bar using Qtcreator?

[himanshu chauhan]

I want to create a button named as "Log Out" in the title bar in the rightmost corner of the application.

@himanshu-chauhan I don't think you can do that with Qt, unless you implement your own title bar (title bar is handled by the OS window manager, not Qt).
Also, this would be unusual: why do you want to put a button in the title bar?

Ok thanks.
If I ever had multiple users than I can just make use of that logout button.

@himanshu-chauhan Yes, but this button does not have to be in the title bar :-)
There are applications putting UI controls into title bar (like Firefox), but most don't do this.
You would either have to use native APIs or implement the title bar by yourself.
