Yes, it's the end of the code:
// defining
*private SingleSelectionModel<MyType> selectionModel =**
new SingleSelectionModel<MyType>();*
// inside TreeViewModel ctor (or in a better place)
* selectionModel.addSelectionChangeHandler(new
SelectionChangeEvent.Handler() {**
public void onSelectionChange(SelectionChangeEvent event) {
// fire rpc, a place change or something else
** // event.getSelectedObject() contain**s the selected element
}
});*
// return the DefaultNodeInfo with info about the selection strategy
public <T> NodeInfo<?> getNodeInfo(T value) {
// do something with the value and return the right DefaultNodeInfo
if(value instanceof MyType1) {
return new DefaultNodeInfo<SectionDTO>(
new SectionDataProvider(),
new MyCustomCellOrADefaultOne(),
*selectionModel*,
null);
}
else if ...
}
