17 ** Widget values depend on the Widget type:
19 ** widget: (name value key enabled data contents/selected)
21 ** label: ("name" "string" NULL NULL NULL NULL)
22 ** BUTTON: ("name" "string" "key" T/F data <default-button-p>)
23 ** CASCADE (button w/menu):
24 ** ("name" "string" "key" T/F data (label|button|button w/menu...))
25 ** INCREMENTAL (button w/menu construction callback):
26 ** ("name" "string" NULL T/F <opaque pointer>)
27 ** menubar: ("name" NULL NULL T/F data (button w/menu))
28 ** scrollbar:("name" NULL NULL T/F NULL NULL)
30 ** ("name" "string" "key" T/F data T/F)
31 ** checkbox: selectable thing
32 ** radio: ("name" NULL NULL T/F data (selectable thing...))
33 ** strings: ("name" NULL NULL T/F data (selectable thing...))
34 ** TEXT: ("name" "string" <ign> T/F data)
36 ** Note that the above is EXTREMELY bogus. The "type" of the various entities
37 ** that a widget_value structure can represent is implicit in the contents of
38 ** half a dozen slots, instead of there simply being a type field. This
39 ** should all be rethunk. I've added a type field, but for now it's only used
40 ** by the new xlwmenu code.
