// Item constructors...
|

//
|
||||
// XXX general design:
|
||||
// - each of these can take either a value or a function (constructor)
|
||||
// - the function has access to Items.* and context
|
||||
// - the constructor can be called from two contexts:
|
||||
// - external
|
||||
// called from the module or as a function...
|
||||
// calls the passed constructor (passing context)
|
||||
// builds the container
|
||||
// - nested
|
||||
// called from constructor function...
|
||||
// calls constructor (if applicable)
|
||||
// builds item(s)
|
||||
// XXX need a way to pass container constructors (a-la ui-widgets dialog containers)
|
||||
// - passing through the context (this) makes this more flexible...
|
||||
// - passing via args fixes the signature which is a good thing...
