Overview
| Comment: | Make exposure menu functional - Make it function so that user is constrained to exposure menu initially and must select value there. - Once selected, the ISO menu becomes active and user must select value there - Finally make both shutter and aperture menus actives (switch between them with left/right arrow keys). Whichever is selected, the other will be calculated. This is not very pretty: - I don't like having both the selection_counter and menu_counter. Seems almost redundant. Made sense before I constrained selections and stepped through the menu's etc (and therefore you could re-select), but now seems annoying to have to keep it only for how last two menus work. - I don't like the repetitive menu creation stuff. That should be DRY-ed up. |

| 10:33 | For ref: Try wrapping menu and window creation in single function Got this so it drew everything ok, but segfaults as soon as a key is pressed. I obviously don't understand pointers, etc properly yet. As although it's drawn the menus it hasn't "attached" them the the objects/pointers I was expecting. check-in: a88f7285c1 user: base@atomicules.co.uk tags: origin/master, trunk | |

| 12:38 | Add in EV menu, doesn't function yet though - Add in free memory bits, also missed some for the other menus check-in: 6c315c3200 user: base@atomicules.co.uk tags: origin/master, trunk | |
