Hi,

i have a multicolumn tree with a treeviewer. At some point i need to get the model object given a TreeItem. How can I do this? as it is easier with tableviewer using tableviewer.getElementAt(index). I think i have to use treeviewer.getVisibleExpandedElements() but how?

EDIT: and yes i select the leave node which is not retrieved by treeviewer#getVisibleExpandedElements() Sad

. I need the model object of the selected leave node

appreciate any help.
Mok

Hi,

one solution is to work with TreeSelection:

((TreeSelection) getViewer().getSelection());
(IStructuredSelection) getViewer().getSelection();

JFace sets the element as the un-named data object, so you can get the
element by simply calling the TreeItem:getData method.
