Ahh I got it working with this code:
public void setSelectionModel() {
final SingleSelectionModel<Member> selectionModel = new
SingleSelectionModel<Member>();
Handler selectionHandler = new SelectionChangeEvent.Handler() {
public void onSelectionChange(SelectionChangeEvent
event) {
Member member =
selectionModel.getSelectedObject();
eventBus.fireEvent(new
ShowMemberEvent(member.getBarcodeID()));
}
};
selectionModel.addSelectionChangeHandler(selectionHandler);
this.display.setSelectionModel(selectionModel);
}
is that the normal way?
