Hi!
I only see the childs of the main TreeEditPart in the outline view. The main
TreeEditPart ist the corresponding TreeEditPart to the RootEditPart of the
editor. Both have the same model, which is also the top-level parent in my
model.
How can I configure the outline view to display this root as the firt point
and all childs in a tree under it?
Cu, Gunnar

Hello Randy:
I have the some question about how to display the tree root info in
outline.I have seen all the message about this topic,but i still can't
understand how to use a treeitem instead of the tree as other treeitem's
parent.Is it the tree has been there when you add a new TreeViewer to the
outlinePage?if it's true, how i can replace a tree with a treeitem ?
I try to implement it like this:
In the TreeEditPart refreshVisuals{
if (getWidgest() return tree)
{
Tree tree = (Tree) getWidgest();
TreeItem parentItem = new TreeItem(tree, SWT_STYLE);
parentItem.setText("root");
return;}
TreeItem item = (TreeItem)getWidgest();
item.setText("item");
}
but it can't work ,first when the treeItem added to outline eclipse throws a
nullpointerexception for there is no editpart when AbstractEditPartViewer
call
setSelection(),then the parentItem is added the some level of other treeItem
instead of as their parent.
Waiting for you advice ,thanks in advance.
