I noticed on the Xwt Wiki it stated that Cavas, Paned, HBox, VBox and Table are listed as Container classes, and suspect that leaving out ScrolledView was an oversight, so I update the wiki to show this as a container.
However, it actually seems that Frame and Window are also containers, because they allow a ".Content=", same as a Paned allows.
Have I misunderstood how the container classes are defined, so should we be listing all these as containers? If so, I will happily update the Wiki to show all these as containers...
