3.20  group-box-panel%

Superclass: vertical-panel%

A group-box panel arranges its subwindows in a single column, but also draws an optional label at the top of the panel and a border around the panel content.

Unlike most panel classes, a group-box panel's horizontal and vertical margins default to 2.

• (instantiate group-box-panel% () (label _) (parent _) [(style _)] [(enabled _)] [(vert-margin _)] [(horiz-margin _)] [(border _)] [(spacing _)] [(alignment _)] [(min-width _)] [(min-height _)] [(stretchable-width _)] [(stretchable-height _)]) -> group-box-panel% object
     label : string (up to 200 characters)
     parent : frame%, dialog%, panel%, or pane% object
     style = null : list of symbols in '(deleted)
   enabled = #t : boolean
     vert-margin = 2 : exact integer in [0, 1000]
     horiz-margin = 2 : exact integer in [0, 1000]
     border = 0 : exact integer in [0, 1000]
     spacing = 0 : exact integer in [0, 1000]
     alignment = '(center top) : two-element list: 'left, 'center, or 'right and 'top, 'center, or 'bottom
   min-width = 0 : exact integer in [0, 10000]
     min-height = 0 : exact integer in [0, 10000]
     stretchable-width = #t : boolean
     stretchable-height = #t : boolean

  Creates a group pane whose title is label.

  If style includes 'deleted, then the group panel is created as hidden, and it does not affect its parent's geometry. The group panel can be made active later by calling parent's add-child method.

  For information about the enabled argument, see window<%>. For information about the horiz-margin and vert-margin arguments, see subarea<%>. For information about the min-width, min-height, stretchable-width, and stretchable-height arguments, see area<%>.
