GroupBox

The GroupBox is a labeled box surrounding a group of fields on a screen for visible grouping of like items. One of the most common uses of the GroupBox is to group RadioButtons together so they can determine their "siblings" by having a common parent. A GroupBox is actually a subclass of the StaticRect class.
