/* * Mac OS X / Cocoa front end to puzzles. * * Still to do: * * - I'd like to be able to call up context help for a specific * game at a time. * * Mac interface issues that possibly could be done better: * * - is there a better approach to frontend_default_colour? * * - do we need any more options in the Window menu? * * - can / should we be doing anything with the titles of the * configuration boxes? * * - not sure what I should be doing about default window * placement. Centring new windows is a bit feeble, but what's * better? Is there a standard way to tell the OS "here's the * _size_ of window I want, now use your best judgment about the * initial position"? * + there's a standard _policy_ on window placement, given in * the HI guidelines. Have to implement it ourselves though, * bah. * * - a brief frob of the Mac numeric keypad suggests that it * generates numbers no matter what you do. I wonder if I should * try to figure out a way of detecting keypad codes so I can * implement UP_LEFT and friends. Alternatively, perhaps I * should simply assign the number keys to UP_LEFT et al? * They're not in use for anything else right now. * * - see if we can do anything to one-button-ise the multi-button * dependent puzzle UIs: * - Pattern is a _little_ unwieldy but not too bad (since * generally you never need the middle button unless you've * made a mistake, so it's just click versus command-click). * - Net is utterly vile; having normal click be one rotate and * command-click be the other introduces a horrid asymmetry, * and yet requiring a shift key for _each_ click would be * even worse because rotation feels as if it ought to be the * default action. I fear this is why the Flash Net had the * UI it did... * + I've tried out an alternative dragging interface for * Net; it might work nicely for stylus-based platforms * where you have better hand/eye feedback for the thing * you're clicking on, but it's rather unwieldy on the * Mac. I fear even shift-clicking is better than that. * * - Should we _return_ to a game configuration sheet once an * error is reported by midend_set_config, to allow the user to * correct the one faulty input and keep the other five OK ones? * The Apple `one sheet at a time' restriction would require me * to do this by closing the config sheet, opening the alert * sheet, and then reopening the config sheet when the alert is * closed; and the human interface types, who presumably * invented the one-sheet-at-a-time rule for good reasons, might * look with disfavour on me trying to get round them to fake a * nested sheet. On the other hand I think there are good * practical reasons for wanting it that way. Uncertain. * * - User feedback dislikes nothing happening when you start the * app; they suggest a finder-like window containing an icon for * each puzzle type, enabling you to start one easily. Needs * thought. * * Grotty implementation details that could probably be improved: * * - I am _utterly_ unconvinced that NSImageView was the right way * to go about having a window with a reliable backing store! It * just doesn't feel right; NSImageView is a _control_. Is there * a simpler way? * * - Resizing is currently very bad; rather than bother to work * out how to resize the NSImageView, I just splatter and * recreate it. */ #ifndef COMBINED #error Expected -DCOMBINED to come from the makefile #endif #include <ctype.h> #include <time.h> #include <sys/time.h> #import <Cocoa/Cocoa.h> #include "puzzles.h" /* ---------------------------------------------------------------------- * Global variables. */ /* * The `Type' menu.
