2 * Mac OS X / Cocoa front end to puzzles.
6 * - I'd like to be able to call up context help for a specific
9 * Mac interface issues that possibly could be done better:
11 * - is there a better approach to frontend_default_colour?
13 * - do we need any more options in the Window menu?
15 * - can / should we be doing anything with the titles of the
16 * configuration boxes?
18 * - not sure what I should be doing about default window
19 * placement. Centring new windows is a bit feeble, but what's
20 * better? Is there a standard way to tell the OS "here's the
21 * _size_ of window I want, now use your best judgment about the
23 * + there's a standard _policy_ on window placement, given in
24 * the HI guidelines. Have to implement it ourselves though,
27 * - a brief frob of the Mac numeric keypad suggests that it
28 * generates numbers no matter what you do. I wonder if I should
29 * try to figure out a way of detecting keypad codes so I can
30 * implement UP_LEFT and friends. Alternatively, perhaps I
31 * should simply assign the number keys to UP_LEFT et al?
32 * They're not in use for anything else right now.
34 * - see if we can do anything to one-button-ise the multi-button
35 * dependent puzzle UIs:
36 * - Pattern is a _little_ unwieldy but not too bad (since
37 * generally you never need the middle button unless you've
38 * made a mistake, so it's just click versus command-click).
39 * - Net is utterly vile; having normal click be one rotate and
40 * command-click be the other introduces a horrid asymmetry,
41 * and yet requiring a shift key for _each_ click would be
42 * even worse because rotation feels as if it ought to be the
43 * default action. I fear this is why the Flash Net had the
45 * + I've tried out an alternative dragging interface for
46 * Net; it might work nicely for stylus-based platforms
47 * where you have better hand/eye feedback for the thing
48 * you're clicking on, but it's rather unwieldy on the
49 * Mac. I fear even shift-clicking is better than that.
51 * - Should we _return_ to a game configuration sheet once an
52 * error is reported by midend_set_config, to allow the user to
53 * correct the one faulty input and keep the other five OK ones?
54 * The Apple `one sheet at a time' restriction would require me
55 * to do this by closing the config sheet, opening the alert
56 * sheet, and then reopening the config sheet when the alert is
57 * closed; and the human interface types, who presumably
58 * invented the one-sheet-at-a-time rule for good reasons, might
59 * look with disfavour on me trying to get round them to fake a
60 * nested sheet. On the other hand I think there are good
61 * practical reasons for wanting it that way. Uncertain.
63 * - User feedback dislikes nothing happening when you start the
64 * app; they suggest a finder-like window containing an icon for
65 * each puzzle type, enabling you to start one easily. Needs
68 * Grotty implementation details that could probably be improved:
70 * - I am _utterly_ unconvinced that NSImageView was the right way
71 * to go about having a window with a reliable backing store! It
72 * just doesn't feel right; NSImageView is a _control_. Is there
75 * - Resizing is currently very bad; rather than bother to work
76 * out how to resize the NSImageView, I just splatter and
