[news.eclipse.platform.swt] Trees and Tables

[t.wilhelm@xxxxxx (T. Wilhelm)]

Hey all,

i have a general question about Trees and Tables. I wondering why Trees 
and Tables are derived from composite and do not have a common base (or 
interface) class where methods like getItemHeight(), getHeaderHeight(), 
getColumn() and so on are placed. In JFace i found a better structured 
hierachy, because there is the 
StructuredViewer->ColumnViewer->Table/TreeViewer.

Maybe i overlooked something? Or is there any good reason for that design? 

Thanks alot
Thomas
