== Creating a Slot Metaclass ==

{{PrF_UG_TOC_meta}}<div id='prf_ug'>

<b>Note:</b> <i>Before you create and use metaclasses,
you should be confident with the basic {{#var:PrF}} interface and be comfortable designing a project,
and creating and modifying classes,
slots,
forms and instances.</i>

Creating a slot metaclass is almost identical to creating a
[[PrF_UG_meta_metaclass_create|metaclass]].
You simply have to make sure the class is created subordinate to <b>:SLOT</b>.
Usually,
it is desirable to create a slot metaclass subordinate to <b>:STANDARD-SLOT</b>,
so that the slot created using the slot metaclass will have the various properties defined by <b>:STANDARD-SLOT</b>.

To create a new slot metaclass:

<ol class='a'>
<li><p>
Click on the desired superclass in the Class Browser.
The selected superclass must itself be a slot metaclass.
As mentioned above,
this will be true only if the selected superclass is subordinate to <b>:SLOT</b>.

</p><p> <div>[[Image:PrF_UG_meta_metaslot_hierarchy.png|metaclasses_metaslot_hierarchy]]</div>
</p>

<li><p>
Click the <b>Create Class</b>
[[Image:PrF_UG_classes_class.create.gif|classes_class.create]]
button at the right of the Class Browser,
or click the right mouse button and select <b>Create subclass</b> from the
[[PrF_UG_classes_class_menu|Class Menu]].
The new class will be added under the highlighted class.
It will inherit the properties of the selected metaclass.

</p><p> <div>[[Image:PrF_UG_meta_metaslot_new.png|metaclasses_metaslot_new]]</div>
</p>

<li><p>
Use the
[[PrF_UG_classes_class_editor|Class Editor]]
to name the slot metaclass,
create constraints,
and create and edit template slots.
For example,
click the <b>Create Slot</b>
[[Image:PrF_UG_slots_slot.create.gif|slots_slot.create]]
button at the right of the Template Slots pane to create a new slot.
This slot will show up as an entry field in the
[[PrF_UG_slots_slot_editor|Slot Editor]]
for any slot that uses the slot metaclass.
</p>
</ol>
