Sliding around on the Ipod * scrollwheel will move the icons around. If you stop * scrolling the icons will refocus on the one icon closest * to the center. This is the icon you would 'select' if the * select key is clicked. * * For the devices without a scrollwheel, the left and right * button lets you scroll through the menu. This is just not * as elegant as the scrollwheel (however it is very effective). * * 'Menu' takes you back to the menu. * * things to do: * - Do something when 'select' is clicked. * - Insert this code into the existing menu drawing code so * the graphical menu is shown for Ipod videos on the * playlist/plugins menu. * - Scaling of the icons is done outside of Rockbox, just 10 * variations of each icon have been provided to the plugin. * This is not the most memory effective way), However it is * the fastest solution (and I get away with not writing * code for real-time scaling...) */ PLUGIN_HEADER /* Key assignement */ #if (CONFIG_KEYPAD == IPOD_4G_PAD) || \ (CONFIG_KEYPAD == IPOD_3G_PAD) #define GFXMENU_ACTION BUTTON_ACTION #define GFXMENU_QUIT BUTTON_MENU #define GFXMENU_RIGHT2 BUTTON_LEFT #define GFXMENU_LEFT2 BUTTON_RIGHT #define GFXMENU_RIGHT BUTTON_SCROLL_FWD #define GFXMENU_LEFT BUTTON_SCROLL_BACK #elif (CONFIG_KEYPAD == IAUDIO_X5_PAD) #define GFXMENU_QUIT BUTTON_POWER #define GFXMENU_RIGHT BUTTON_RIGHT #define GFXMENU_LEFT BUTTON_LEFT #define GFXMENU_RIGHT2 BUTTON_UP #define GFXMENU_LEFT2 BUTTON_DOWN #elif (CONFIG_KEYPAD == GIGABEAT_PAD) #define GFXMENU_QUIT BUTTON_A #define GFXMENU_RIGHT BUTTON_RIGHT #define GFXMENU_LEFT BUTTON_LEFT #define GFXMENU_RIGHT2 BUTTON_UP #define GFXMENU_LEFT2 BUTTON_DOWN #else #define GFXMENU_QUIT BUTTON_NAVI #define GFXMENU_RIGHT2 BUTTON_UP #define GFXMENU_LEFT2 BUTTON_DOWN #define GFXMENU_RIGHT BUTTON_RIGHT #define GFXMENU_LEFT BUTTON_LEFT #endif /* external bitmaps */ extern const fb_data gfxmenu_menuitems48[]; extern const fb_data gfxmenu_menuitems47[]; extern const fb_data gfxmenu_menuitems46[]; extern const fb_data gfxmenu_menuitems45[]; extern const fb_data gfxmenu_menuitems44[]; extern const fb_data gfxmenu_menuitems43[]; extern const fb_data gfxmenu_menuitems42[]; extern const fb_data gfxmenu_menuitems41[]; extern const fb_data gfxmenu_menuitems40[]; extern const fb_data gfxmenu_menuitems39[]; extern const fb_data gfxmenu_menuitems38[]; #define CALCX(x) x * LCD_WIDTH #define CALCY(y) y * LCD_HEIGHT #define ICON_SIZE_MAX 48 #define ICON_SIZE_MIN 38 // GFXMENU_WAIT_FOR_FOCUS is the number of cycles to wait // before automatic focussing to the center. #define GFXMENU_WAIT_FOR_FOCUS 10 // GFXMENU_STEP is the step size when using the scroll wheel // 1 is very nice, but slow (needs a lot of scrolling). // 4 seems okay (3 revolutions on scrollwheel for one revolution on screen). #define GFXMENU_STEP 4 static struct plugin_api* rb; const int path_elements = 180; const int focus_in_path = 90; // GFXMENU_MAX_MENU_ELEMENTS is the maximum number of menuitems // to be allocated by the application.
