Hi Antony,
great to see Scala and Wicket getting more popular. :-)
I've been using them together quite a while now and am convinced
that there are
lots of benefits in it!
I created a dynamic component (like wicket:component which isn't
officially
supported) which also works with Ajax. There's also a 'VarModel'
which is
similar to your Fodel. You'll find the sources here:
http://www.footprint.de/fcc/2008/11/some-wicket-scala/
I also use Scala's mixin capabilities to abstract layout
information out of the
pages/components. E.g. to define cell styles of datatable columns
or to format
cell output, I have something like:
trait Centered[T] extends IStyledColumn[T] {
abstract override def getCssClass: String = {
val style = super.getCssClass
if( style==null ) "columnCentered"
else style + " " + "columnCentered"
}
}
trait DateFormat[T] extends PropertyColumn[T] {
override protected def createLabelModel( embeddedModel:
IModel[T] ):
IModel[_] = {
val m = super.createLabelModel( embeddedModel )
m.getObject match {
case dt: DateTime =>
VarModel( dt.toString( dateFormatter.withLocale(
getLocale ) ) )
case _ => m
}
}
}
To create/apply a cell to use this style I just have to apply this
trait:
val col1 = new PropertyColumn[M]( new Model( "Date" ), COL_DATE,
"reg_date" )
with Centered[M] with DateFormat[M]
Scala's just great to abstract more between logic and layout.
