horizontal-panel% : class?

  superclass: panel%

A horizontal panel arranges its subwindows in a single row. See also panel%.

The style flags are the same as for panel%.

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<%>.

(send a-horizontal-panel set-orientation horizontal?) → void?
  horizontal? : boolean?
Sets the orientation of the panel, switching it between the behavior of the vertical-panel% and that of the horizontal-panel%.

(send a-horizontal-panel get-orientation) → boolean?
Initially returns #t, but if set-orientation is called, this method returns whatever the last value passed to it was.
