Commit 336c338c authored by Andrew den Exter's avatar Andrew den Exter Committed by Qt by Nokia

Fix text wrapping and eliding with implicitWidth.

Update the implicitWidth of the item before continuing with the layout
rather than after it's completed this gives any bindings dependent on
the implicitWidth the opportunity to update the width before the layout
continues.
