Getting the type of a control

[Ben Rubinstein]

Is there a clean way to get the type of a control?

If I write a script that goes through the controls of a stack in order, I
can get the properties of each control, and list them.  The only property I
don't seem to be able to get is what type of control it is - field, button,
etc.  You can even get the number property, which is dependant on the type -
eg if you have a group containing a field, a button, and another field, you
get
    layer number
    1       1  - first group
    2       1  - first field
    3       1  - first button
    4       2  - second field

...but I can't see anything to return the type.  The workaround I've found
is to get first word of the long name - but that seems like a hack.  Is
there a clean way?

TIA,
