layout-spacing

The class of layout-spacing sub-objects of object-editor dialogs. If the default spacing that is used when an object-editor automatically lays out its widgets is not satisfactory, then the object-editor can be given a layout-spacing object whose properties specify custom spacing values.

The Class Interface Editor dialog does not include widgets for specifying this value interactively, but it could edited in the Inspect dialog after the Class Interface Editor sets up an object-editor form window.

Creating an object-editor programmatically with a layout-spacing sub-object would have this general format:

(make-window :my-object-editor
  :class 'object-editor
  :edited-class ...
  :edited-slots ...
  :layout-spacing (make-instance 'layout-spacing
                    :layout-widget-spacing 4
                    :layout-outer-margin 12
                    ...))

Here are the particular properties of a layout-spacing object:

• layout-outer-margin
• layout-widget-width
• layout-single-line-widget-height
• layout-multi-line-widget-height
• layout-widget-spacing
• layout-label-spacing
• layout-column-spacing
• layout-button-height
• layout-button-width
• layout-button-spacing
• layout-button-group-spacing
• layout-table-height
