Is it possible using API to display the dialog which connect to object like as attached picture?
This is useful to show object information.
NX does not have any built in API to create these small 'temporary' dialogs (as far as I know).
But you could get something more like you want with some careful usage of the following (or their wrapper methods):
You could possibly even create a tiny WinForms dialog that sat at the end of the leader line you displayed. But that's an awful lot of work for a simple label.
