Using XScalaWT, this compiled under Scala 2.7:
class NodeView(parent: Composite) extends Composite(parent) {
var nodeName: Label = null
this.contains(
label(
nodeName = _
)
)
}
With 2.8.0 RC1, I get this error:
type mismatch; found : main.scala.NodeView required: org.eclipse.swt.widgets.Label
The types are:
label(setups: (Label => Unit)*)(parent: Composite) : Label
contains(setups: (W => Unit)*) : W
So it looks like _ now binds to the outer function instead of inner.
Is this change intentional?
