(newButton Able Dst Args)

This function makes a button used to create a new object. The following code comes from the demo app supplied with the PicoLisp distribution, in gui.l, and makes a button that when clicked creates a new object of the class +CuSu. The new object is initialised with the values used in a search for an existing one, if any such terms have been entered.

    (newButton T Dst '(+CuSu)
       '(nr genKey 'nr '+CuSu)
       'nm *CuSuNm
       'plz *CuSuPlz
       'ort *CuSuOrt
       'tel *CuSuTel
       'mob *CuSuMob )
