Another Question with StyleSheets

[daiheitan]

Thanks.In fact just a few minutes ago I solved this problem just like Lykurg did.I read the file into a QString and replaced all "url(./" to absolute Path.

Another question:
In Windows vista&7, the maximize,minimize and close button are put in a line and there 's no space between them.But when one button is hovered, the button has shadow.The most important is :the shadow is partly on the other buttons.

In Qt,a QPushButton could also look different by using a PNG file(e.g: a shadow Button) as backgound-image when hovered.But,two widgets could not overlap each other.
I wonder how to do it in Qt to create a group of vista-like buttons.

Or anyone know how to create a Google Chrome-style UI?(No titleBar But has the windows control Buttons)?
Still, waiting online for any reply.
