Class

Summary

The row-layout class lays its children out in a row.

Package

capi

Superclasses

grid-layout

Initargs

:ratios

The size ratios between the layout's children.

:adjust

The vertical adjustment for each child.

:gap

The gap between each child.

:uniform-size-p

If t , each child in the row has the same width.

Accessors

layout-ratios

Description

This 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 arguments x-ratios , y-adjust , x-gap and x-uniform-size-p .

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

Examples

(setq row (capi:contain

           (make-instance

            'capi:row-layout

            :description

            (list

             (make-instance 'capi:push-button

                            :text "Press me")

             (make-instance 'capi:title-pane

                            :text "Title")

             (make-instance 'capi:list-panel

                            :items '(1 2 3)))

            :adjust :center)))

(capi:apply-in-pane-process 

 row #'(setf capi:layout-y-adjust) :bottom row)

(capi:apply-in-pane-process 

 row #'(setf capi:layout-y-adjust) :top row)

This last example shows a row with a stretchable dummy pane between two other elements which are fixed at their minimum size. Try resizing it:

(capi:contain

 (make-instance 'capi:row-layout

                :description 

                (list (make-instance 'capi:push-button

                                     :text "foo")

                      nil

                      (make-instance 'capi:push-button

                                     :text "bar"))

                :ratios '(nil 1 nil)))
