Linux application looks ugly when launched with sudo

Good day, colleagues!

I'm writing Linux application that needs root privelleges. The problem is when I launch it from normal user, it looks nice, but when I launch it with sudo it looks ugly (wrong style, fonts, etc).

Could you explain such behaviour?

Strange,
But mayby thats because root has different windowmanager settings.
Do you work with stylesheets?

No, I've just create simple window in Qt Designer.

Thats what i tought,
your 'sudo' window is in motif style.

Maybe this "link":http://helpforlinux.blogspot.com/2009/01/make-sudo-applications-beautiful.html could help.

Try running qtconfig via sudo and changing the default widget style to plastique or oxygen or whatever takes your fancy.

Executing an application with "sudo", takes the default theme, so not style configuration is applied.
You can customize the root theme, but is a solution per machine, or maybe you can set the style of the application through code with Qt.

Thank you all, sudo qtconfig did the trick!
