Hi all,
How can we change the selection on clicking a child node to its
parent node. So that I can view the properties of the parent node in the
property view even on selecting child node(which is my requirement).
Thanks, Biju

Hi all,
Got it, I did it by adding a selection listener and changing the
selection in the child edit part, as follows.I am calling the following
method from the createDefaultEditPolicies() function of my child edit
part.
Thanks, Biju
private void addSelectionListener() {
this.getViewer().addSelectionChangedListener(new
ISelectionChangedListener(){
@Override
public void selectionChanged(SelectionChangedEvent selectionEvent) {
if(selectionEvent.getSelection() instanceof StructuredSelection){
StructuredSelection selection=(StructuredSelection)
selectionEvent.getSelection();
if(selection.getFirstElement() instanceof ConveyorSlotEditPart){
getViewer().setSelection(new
StructuredSelection(((ConveyorSlotEditPart)selection.getFirs tElement()).getParent()));
}
}
}
});
}

Hi Biju,
You may use isSelectable() method to control selectability of the node.
If the node is not selectable, the node underneath will get selected
(and normally, it is the parent node).
Another solution is to override method getTargetEditPart in your
(non-)resizable edit policy to return getHost().getParent() as the
target edit part for the REQ_SELECTION request.
Your solution is also ok, but seems to leak deleted edit parts for the
lifetime of the graphical viewer.
Best regards,
Boris

Hi Boris Blajer,
Thanks for your Idea,
Its working better, and is simple, I just override the
isSelectable() of child edit part to return false.
Thanks, Biju
