I am programmatically trying to select a node of a tree. I was able to
do everything using tree.setSelection() method. However it doesnt fire
the selection event and hence the handler is never called. If I manually
select the item, the event is fired. Is this correct behavior?
Here is my code registering for the selection event.
tree.addListener(SWT.Selection, new Listener(){
public void handleEvent(Event event) {
TreeItem[] itemsSelected = tree.getSelection();
// do something with the selected items;
}
}

Yes, because you not always want selection event, and if you don't
want and it sent, you have to create flag, set it, check, etc. In
current variant you just need call your handler, if you want.
