4 | * Still to do: |
5 | * |
6 | * - Improve the help. For a start I probably ought to split it |
7 | * into pieces (which means Halibut needs to acquire a mechanism |
8 | * of putting something in the head section of _only one_ HTML |
9 | * file); then I'd also like to be able to call up context help |
10 | * for a specific game at a time. Also I just idly wonder |
11 | * whether changing font might be nice, to match up to Apple |
12 | * norms. |

13 | * |

14 | * Mac interface issues that possibly could be done better: |
15 | * |
16 | * - is there a better approach to frontend_default_colour? |
17 | * |
18 | * - do we need any more options in the Window menu? |
00461804 |
19 | * |
2411c162 |
20 | * - can / should we be doing anything with the titles of the |
21 | * configuration boxes? |
22 | * |
9494d866 |
23 | * - not sure what I should be doing about default window |
24 | * placement. Centring new windows is a bit feeble, but what's |
25 | * better? Is there a standard way to tell the OS "here's the |
26 | * _size_ of window I want, now use your best judgment about the |
27 | * initial position"? |
00461804 |
28 | * |
9494d866 |
29 | * - a brief frob of the Mac numeric keypad suggests that it |
30 | * generates numbers no matter what you do. I wonder if I should |
31 | * try to figure out a way of detecting keypad codes so I can |
6d634196 |
32 | * implement UP_LEFT and friends. Alternatively, perhaps I |
33 | * should simply assign the number keys to UP_LEFT et al? |
34 | * They're not in use for anything else right now. |
00461804 |
35 | * |
00461804 |
36 | * - see if we can do anything to one-button-ise the multi-button |
37 | * dependent puzzle UIs: |
38 | * - Pattern is a _little_ unwieldy but not too bad (since |
39 | * generally you never need the middle button unless you've |
40 | * made a mistake, so it's just click versus command-click). |
41 | * - Net is utterly vile; having normal click be one rotate and |
42 | * command-click be the other introduces a horrid asymmetry, |
43 | * and yet requiring a shift key for _each_ click would be |
44 | * even worse because rotation feels as if it ought to be the |
45 | * default action. I fear this is why the Flash Net had the |
46 | * UI it did... |
47 | * |
e1107f8b |
48 | * - Should we _return_ to a game configuration sheet once an |
49 | * error is reported by midend_set_config, to allow the user to |
50 | * correct the one faulty input and keep the other five OK ones? |
51 | * The Apple `one sheet at a time' restriction would require me |
52 | * to do this by closing the config sheet, opening the alert |
53 | * sheet, and then reopening the config sheet when the alert is |
54 | * closed; and the human interface types, who presumably |
55 | * invented the one-sheet-at-a-time rule for good reasons, might |
56 | * look with disfavour on me trying to get round them to fake a |
57 | * nested sheet. On the other hand I think there are good |
58 | * practical reasons for wanting it that way. Uncertain. |
59 | * |
7e04cb48 |
60 | * Grotty implementation details that could probably be improved: |
61 | * |
62 | * - I am _utterly_ unconvinced that NSImageView was the right way |
63 | * to go about having a window with a reliable backing store! It |
64 | * just doesn't feel right; NSImageView is a _control_. Is there |
65 | * a simpler way? |
66 | * |
67 | * - Resizing is currently very bad; rather than bother to work |
68 | * out how to resize the NSImageView, I just splatter and |
69 | * recreate it. |
