[news.eclipse.tools] Re: having trouble using ViewerSorter

["Nick Edgar" <nick_edgar@xxxxxxx>]

From Tiger's first post, it looks like he's not using a content provider.

Tiger, you should be using setContentProvider and setInput() rather than
adding items directly to the viewer.
When the sorter changes, or when refresh() is called, the viewer asks the
content provider for the elements.
It then sorts them using the sorter and shows them.
The add(), remove() and update() methods on the viewers are intended to be
called by the content provider in response to model changes.
They should not be called by the model itself.
