3.35  panel%

Implements: area-container-window<%>

Implements: subwindow<%>

A panel is a both a container and a containee window. It serves mainly as a geometry management device, but the 'border creates a container with a border. Unlike a pane% object, a panel% object can be hidden or disabled.

A panel% object has a degenerate placement strategy for managing its children; it places them all in the upper left corner and does not stretch any of them. The horizontal-panel% and vertical-panel% classes provide useful geometry management.

• (instantiate panel% () (parent _) [(style _)] [(enabled _)] [(vert-margin _)] [(horiz-margin _)] [(border _)] [(spacing _)] [(alignment _)] [(min-width _)] [(min-height _)] [(stretchable-width _)] [(stretchable-height _)]) -> panel% object
     parent : frame%, dialog%, panel%, or pane% object
     style = null : list of symbols in '(border)
   enabled = #t : boolean
     vert-margin = 0 : exact integer in [0, 1000]
     horiz-margin = 0 : exact integer in [0, 1000]
     border = 0 : exact integer in [0, 1000]
     spacing = 0 : exact integer in [0, 1000]
     alignment = '(left 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

  If the 'border style is specified, the window is created with a thin border (only in this case, the client size of the panel may be less than its total size).

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