pyswt SWT.NULL

[3rdshiftcoder]

hi-

i am trying to make a pyswt gui and when it gets to this line:
 colType = Combo(self.shell, SWT.NULL)

i get:
colType = Combo(self.shell, SWT.NULL)
AttributeError: NULL

when using swt with java i had to have lots of imports at the beginning of a 
swt file.
are they not needed when using pyswt?

thanks for any help,
jim
