| 2 | * Mac OS X / Cocoa front end to puzzles. |
| 3 | * |
| 4 | * Still to do: |
| 5 | * |
| 6 | * - I'd like to be able to call up context help for a specific |
| 7 | * game at a time. |
| 8 | * |
| 9 | * Mac interface issues that possibly could be done better: |
| 10 | * |
| 11 | * - is there a better approach to frontend_default_colour? |
| 12 | * |
| 13 | * - do we need any more options in the Window menu? |
| 14 | * |
| 15 | * - can / should we be doing anything with the titles of the |
| 16 | * configuration boxes? |
| 17 | * |
| 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 |
| 22 | * initial position"? |
| 23 | * + there's a standard _policy_ on window placement, given in |
| 24 | * the HI guidelines. Have to implement it ourselves though, |
| 25 | * bah. |
| 26 | * |
| 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. |
| 33 | * |
| 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 |
| 44 | * UI it did... |
| 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. |
| 50 | * |
| 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. |
| 62 | * |
| 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 |
| 66 | * thought. |
| 67 | * |
| 68 | * Grotty implementation details that could probably be improved: |
| 69 | * |
| 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 |
| 73 | * a simpler way? |
| 74 | * |
| 75 | * - Resizing is currently very bad; rather than bother to work |
| 76 | * out how to resize the NSImageView, I just splatter and |
| 77 | * recreate it. |
