Is there any way to create un-decorated windows in Qt

[premjith]

Is there any way to create un-decorated, borderless with custom close button window in Qt. I want to design it with qt designer , but im not found any option to hide the system default titlebar and controls.

Qt is not responsible for windows border. You can use window border or not. For more information see window flags.

I think this is what you want:
