This feat is accomplished with the help of 3 commands within an external command (XCMD) called "ButtonRgn". These commands are:

NewRgn: Creates the shape(s) of the new button(s) and pastes them on the screen.

TestHit: Checks the mouse locations against all the regions. Returns the number of the button hit or zero if none hit.

DisposeRgn: Removes the button regions from memory. Does NOT erase them from the screen.
