TreeViewer and LabelProvider [message #453459]

Background:
I need to remove all deprecated code from a project migrated from RCP
3.0 to 3.1M6.

I am somewhat confused about the migration from TableTree to Tree:
- Why isn't TableTreeViewer deprecated as TableTree is?
- How am I supposed to do multi column trees using a label provider?
(TreeViewer only supports an ordinary ILabelProvider instead of a
ITableLabelProvider)

Any hints or comments are highly appreciated.

I have a the following label provider class and it works

class ViewLabelProvider extends LabelProvider implements ITableLabelProvider

Add columns to the tree of your viewer, this way the label provider will be
called with the column argument.

viewer.getTree().setLinesVisible(true);
TreeColumn tcTree = new TreeColumn(viewer.getTree(), SWT.LEFT);
tcTree.setWidth(200);
tcTree.setResizable(true);
TreeColumn tcIcon = new TreeColumn(viewer.getTree(), SWT.CENTER);
tcIcon.setResizable(false);
tcIcon.setWidth(50);

Thank you for your advice - it works now well!

One more question: Do you know how whether it is possible to make the
table cells in a Treetable editable?
