## dialog-units-p

Arguments: dialog-item

Returns whether dialog-item's coordinates are specified in dialog-units rather than in pixels. If true, then the dialog-item's coordinates are measured in dialog-units, which are defined as one-fourth of a system-font space width wide or one-eighth of a system-font line-height high. If `nil`, the coordinates are in pixels, which are the coordinates that are usually used by common graphics.

Dialog-items will be created using pixel coordinates unless the :dialog-units-p initarg is passed as true when creating the `dialog-item` with make-instance.

Because the system-font varies from one machine to the next, using dialog-units is discouraged.
