Hello,
I've build a TreeViewer like the Mail-example.
The TreeViewer is build by a TreeParent with TreeParents and TreeObjects.
I add a DoubleClickEvent to open new views by clicking on the treeView. At
this event I check which Tree-Element has been selected, but I only can
check the elements' String and not the hole Elements-data.
some code:
viewer.addDoubleClickListener(new IDoubleClickListener(){public void
doubleClick(DoubleClickEvent event) {
...
IStructuredSelection selection = (IStructuredSelection)
event.getSelection();
String selectedString = selection.getFirstElement().toString();
Is there a way to get Access to the TreeObject which has been selected?
Thanks, Rob

Rob,
if the selection isn't empty, getFirstElement() will return your
model-object, presumably TreeObject/TreeParent in your case.
You need to explicitly cast the returned object.
