- DEFINITION MODULE DuWindow;
-
- (*
- PART OF DirUtil for Modula 2
-
- This creates, opens and maintains the DirUtil window.
- It contains a couple of other importable routines for
- user alteration.
-
- Written: 3/21/87 by Greg Browne
-
- Compiles on TDI's Modula-2 Compiler version 2.20a
-
- NOTES: I kept being bugged with RefreshWindow not being exported from
- Intuition as a flag. Then I found that it is either misspelled
- in the .def module (as ResfreshWindow) or that it is supposed
- to mean ResetFreshWindow. Don't know whats up but it works now.

- Gadgets are addressed as a set. First are the devices, then the message
- string gadgets, then the command gadgets, and finally the slider. Note
- that this is larger than a BITSET already, so the 'GadgetID' is passed as
- a set name and converted as CARDINAL(ORD(whatever)). Expansion of the set
- should be easy, with only screen positioning being the hard part.
