# Renaissance Outlets and Actions
Use XML elements and attributes in your `.gsmarkup` file to wire up outlets and actions between objects in the markup, and to the file's owner.

### Object references

Set the `id` attribute on an object element to give that object a unique identifier that you use when you reference it in outlets and actions. For example, if you define an `NSImageView` as `<image id="profileImageView" editable="YES"/>`, then you refer to it in an outlet or action as `#profileImageView`.

Refer to the file's owner as `#NSOwner`. The file's owner is the object you pass when you load the markup using `-[NSBundle loadGSMarkupNamed:owner:]`.

### Outlets

Connect outlets in a `<connections/>` block in your `.gsmarkup` file. The block contains any number of `<outlet/>` elements. Outlets have the following attributes:

 - `source`: The object that owns the connection. This is the object that has the outlet property you're connecting.
 - `target`: The destination object for the connection. This is the object that you want to connect to the outlet.
 - `key`: The name of the outlet.

For example:

```xml
<connections>
	<outlet source="#NSOwner" target="#window" key="window"/>
</connections>
```

### Actions

Connect an action to a receiver using the `target` attribute on the object that has the action. Use the `action` attribute to set the selector that it invokes on the receiver when the action occurs; include a colon in the action name if the action method has a parameter. For example:

```xml
<image id="imageView" editable="yes" target="#NSOwner" action="imageDropped:"/>
```
