Highlighting a set of controls on mouse hover.

[GAURAV PANT]

Hi
I am developing an existing GUI application which is developed in C# to QT.
I want to highlight a set of controls i.e one check box and a push button on mouse hover i.e when mouse is over any of these controls then both check box and push button both gets highlited or a round box will highlight both of them.
I c# StackPanel is used to group items together. Is there any stackpanel equivalent in QT or is there any other way to highlight group a set of controls.
Thanks.
