How to capture the cursor in a window?

Question

C++ / C#

How to capture the cursor in the window (in the sense of restricting its movement within the window)?
I know that there is a function in WinApi ClipCursor. But maybe there is something better/more convenient in Builder (Embarcadero RAD C++ Builder 10.4)?

Answer 1

Make the app full screen. Otherwise, you will have to put low-level hooks on mouse movement to limit its movement (bad practice, it is better not to do this)
