information from the desktop to a Delphi app

When I switch from my application (MyApp) to another application (App), I can see, that my application still is receiving some inputs. For example I can detect when the cursor moves over MyApp even if MyApp is not the active/focused one. I can receive the input in OnMouseEnter.
Is it possible for MyApp to receive information of the movement of App, if App is dragged across the window of MyApp??
