Class

Summary

The column-layout lays its children out in a column.

Package

capi

Superclasses

grid-layout

Initargs

:ratios

The size ratios between the layout's children.

:adjust

The horizontal adjustment for each child.

:gap

The gap between each child.

:uniform-size-p

If t , each child in the column has the same height.

Accessors

layout-ratios

Description

The column-layout lays its children out by inheriting the behavior from grid-layout. The description is a list of the layout's children, and the layout also translates the initargs ratios , adjust , gap and uniform-size-p into the grid-layout's equivalent initargs y-ratios , x-adjust , y-gap and y-uniform-size-p .

description may also contain the keyword :divider which automatically creates a divider as a child of the column-layout . When specifying :ratios in a column with :divider , you should use nil to specify that the divider is given its minimum size, as in the example below.

Example

(capi:contain (make-instance

               'capi:column-layout

               :description

                (list

                 (make-instance 'capi:push-button

                                :text "Press me")

                "Title"

                (make-instance 'capi:list-panel

                               :items '(1 2 3)))))

(setq column (capi:contain

              (make-instance

               'capi:column-layout

               :description

               (list

                (make-instance 'capi:push-button

                               :text "Press me")

                "Title:"

                (make-instance 'capi:list-panel

                               :items '(1 2 3)))

               :adjust :center)))

(capi:apply-in-pane-process

 column #'(setf capi:layout-x-adjust) :right column)

(capi:apply-in-pane-process

 column #'(setf capi:layout-x-adjust) :left column)

(capi:apply-in-pane-process

 column #'(setf capi:layout-x-adjust) :center column)

(flet ((make-list-panel (x y)

         (make-instance

          'capi:list-panel

          :items

          (loop for i below x

                collect i)

          :selection

          (loop for i below x by y

                collect i)

          :interaction

          :multiple-selection)))

  (capi:contain

   (make-instance

    'capi:column-layout

    :description

    (list

     (make-list-panel 100 5)

     :divider

     (make-list-panel 100 10))

    :ratios '(1 nil 2))))
