Concrete classes must define this.
Concrete classes must define this. It causes the actual DOM node to come into existence.
Fetches the actual rendered DOM Node for this Frag.
Fetches the actual rendered DOM Node for this Frag.
IMPORTANT: this is convenient, but fundamentally unsafe! Only use it in places where you are *certain* that the Node has already been rendered; otherwise, use the safer elemOpt or elemOptRx!
An Rx member containing the actual Node iff it has been rendered.

This is called immediately after this fragment is inserted into its parent, so that you can provide additional stuff that happens then.

Subclasses can override this to define behaviour that happens in the middle of the render function.

The parent of the resulting Node, once it has been created.

We intercept render (which is part of Scalatags), to record the Node when it gets created, and to provide access to the creation event.

IMPORTANT: this imperatively renders the Gadget; if you call it repeatedly, it will render again! Use rendered by preference most of the time.
Lazy version of render().
Lazy version of render(). This returns the rendered content of the Gadget, rendering if need be. This allows you to easily fetch the elem repeatedly, without worrying about re-rendering.
Slam the element for this Gadget.
Slam the element for this Gadget. You should only call this iff the element was created from an external mechanism and you're building this Gadget around that element.
This is intentionally designed for chaining, for ease of use -- it returns this Gadget.
A reactive text Modifier, which lets you place some Text into Scalatags, and have it change when the underlying Rx changes. It does this by setting the .text() jQuery property of the parent node.
Note that this requires an Rx[String] specifically, to keep things simple. Use rx.ops.map to turn other types into Strings.
