LabelProviders and Tree with columns [message #458680] Tue, 19 July 2005 08:03 Go to next message

Hello,
I am new to Eclipse and Java development, so probably I am posing a
trivial question, but I have read the very good articles by Adrian Emmenis
at http://www-128.ibm.com/developerworks/opensource/library/os- ecgui1/ and
I want to extend the project (a simple file explorer) using the new Tree
with columns introduced in 3.1.
However, I don't understand how to rewrite the class FileTreeLabelProvider
in this case to supply labels for every column. It seems I can't, since
the getText() function returns a single String.
Could someone please explain me whether it is possible to solve this
problem and how?
Thanks in advance,

Lanfranco

I am not familiar with the FileTreeLabelProvider, but I have used the new
Tree in 3.1 within a TreeViewer. To get the right calls for columns in the
label provider, the label provider has to be subclassed from
ITableLabelProvider.
