Add a layout field to fwt::Widget.

class Widget
{
  Obj? layout := null
}

Ticket resolved in 1.0.56

Widget.layout now available. This should open the door for some more interesting Panes. Most notably a MigLayout implementation should now be feasible.

Is this analogous to SWT's Composite.layout property or to Control.layoutData?

I have not used that specifically in SWT - but from looking at the javadoc, yes looks like the same thing.

That was an either-or question. :)

Composite.layout controls the layout of the composite's children, whereas Control.layoutData advises the control's parent container how it should be placed out in the container's layout.

I'll assume it is analogous to Control.layoutData since the field is declared in fwt::Widget and not fwt::Pane. Thus:

HBox {
  Label { text = "Description" },
  Text {
    text = model.description ?: "<description>"
    multiLine = true
    layout = HBoxLayout { hExpand = true; vAlign = VAlign.fill }
  },
}

Here the layout property is just advising the container on how the Text control should be aligned.

Is this the intended purpose of this new field?

The intention is that its a hint that may be used by the container Pane. In the case of a MigPane, it would be the string encoding of how its laid out.
