horizontal-panel% : class?
superclass: panel%

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

( new horizontal-panel% |
|  | [parent parent] |
| [ | [style style] |
|  | [enabled enabled] |
|  | [vert-margin vert-margin] |
|  | [horiz-margin horiz-margin] |
|  | [border border] |
|  | [spacing spacing] |
|  | [alignment alignment] |
|  | [min-width min-width] |
|  | [min-height min-height] |
|  | [stretchable-width stretchable-width] |
|  | [stretchable-height stretchable-height]]) |

→ ( is-a?/c horizontal-panel%)

parent

:

( or/c ( is-a?/c frame%) ( is-a?/c dialog%)
( is-a?/c panel%) ( is-a?/c pane%))

style : ( listof ( one-of/c 'border 'deleted)) = null
enabled : any/c = #t
vert-margin : ( integer-in 0 1000) = 0
horiz-margin : ( integer-in 0 1000) = 0
border : ( integer-in 0 1000) = 0
spacing : ( integer-in 0 1000) = 0

alignment

:

( list/c ( one-of/c 'left 'center 'right)
( one-of/c 'top 'center 'bottom))

|  |  | = |  | '(left center)

min-width : ( integer-in 0 10000) = graphical-minimum-width
min-height : ( integer-in 0 10000) = graphical-minimum-height
stretchable-width : any/c = #t
stretchable-height : any/c = #t

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). If style includes 'deleted, then the panel is created as hidden, and it does not affect its parent’s geometry; the 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 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.
