/*! \file * * This is the demo program for the animated menu. We will use to test the MBAF API. * We need to have group item1-item9 in the SVG file. Initially, we will show * item1-item8 only. When a up/down key is pressed, we will draw the next item in item9 and * add two words to move item1-item9 smoothly. The first word move items to the 3/4 position * fastly. The second will move it from 3/4 to the final position slowly to make retard effect. * * If we press another key before the second words finish, we will delete the word and replace * it with a word to move it fastly to the final position and then we will repeat the procedure * to add another two words to move it to the next position. */ #include <stdio.h> #include <mb.h> #include <string.h> #include <dirent.h> //#include "menu.h" #include "mb_af.h" #include <mb_ani_menu.h> struct fileinfo { int height; int width; int depth; int bitrate; int duration; int year; char *comment; }; #define MAX_ENTRY 1000 typedef struct { mb_animated_menu_t *m; char *curDir; struct fileinfo *files[MAX_ENTRY]; char *titles[MAX_ENTRY]; int nFiles; }app_data_t; mbaf_t *app; void myselect(mb_animated_menu_t *m, int select) { app_data_t *data = MBAF_DATA(app,app_data_t); char path[1024]; int len,i; if (strcmp(data->titles[select],"..")==0) { strcpy(path, data->curDir); len = strlen(path); for(i=len-2;i>0;i--) { if (path[i] == '/') { path[i] = 0; break; } } } else { snprintf(path,1024,"%s%s", data->curDir,data->titles[select]); } MyApp_fillDirInfo(app, path); } void mypreview(app_data_t *data, char *path) { redraw_man_t *rdman = MBAF_RDMAN(app); paint_t *paint, *old_paint; shape_t *obj = (shape_t *) MB_SPRITE_GET_OBJ(app->rootsprite, "previewimg"); int w, h; printf("Preview %s\n",path); paint = rdman_img_ldr_load_paint(rdman, path); /* return a cached * paint if the * path was loaded * before */ if (paint) { paint_image_get_size(paint, &w, &h); printf("image %d %d\n",w, h); old_paint = sh_get_fill(obj); rdman_paint_fill(rdman, paint, obj); if(old_paint != paint) rdman_paint_free(rdman, old_paint); rdman_shape_changed(MBAF_RDMAN(app),obj); rdman_redraw_changed(MBAF_RDMAN(app)); } } int endWith(char *path, char *ext) { int i; char *s; s = path+strlen(path)-1; for(i=strlen(ext)-1;i>=0;i--) { if (*s != ext[i]) return 0; s--; if (s < path) return 0; } return 1; } void myupdate(mb_animated_menu_t *m, int select) { app_data_t *data = MBAF_DATA(app,app_data_t); char *s = data->titles[select]; char path[1024]; printf("check %s\n",s); if (endWith(s,".png") || endWith(s, ".jpg") || endWith(s, ".PNG") || endWith(s, ".JPG")) { snprintf(path,1024,"%s%s", data->curDir,data->titles[select]); mypreview(data,path); } } struct fileinfo *fileinfo_new() { struct fileinfo *f = (struct fileinfo *) malloc(sizeof(struct fileinfo)); f->width = 0; f->height = 0; f->depth = 0; f->bitrate = 0; f->duration = 0; f->year = 0; f->comment = NULL; return f; } void fileinfo_free(struct fileinfo *f) { free(f); } MyApp_fillDirInfo(mbaf_t *app,char *curdir) { app_data_t *data = MBAF_DATA(app,app_data_t); DIR *dir; struct dirent *e; struct fileinfo *f; char *path; int sz; int i; dir = opendir(curdir); if (dir == NULL) { printf("We can not open the direftory %s\n", curdir); return; } if (data->curDir) free(data->curDir); sz = strlen(curdir); if(curdir[sz - 1] != '/') sz++; data->curDir = (char *)malloc(sz + 1); strcpy(data->curDir, curdir); if(curdir[sz - 1] == '\0') strcat(data->curDir, "/"); if (data->files) { for(i=0;i<data->nFiles;i++) { fileinfo_free(data->files[i]); free(data->titles[i]); } } data->nFiles = 0; while(e = readdir(dir)) { if (strcmp(e->d_name,".")==0) continue; if (e->d_type == DT_DIR) { if (data->nFiles < MAX_ENTRY) { f = fileinfo_new(); data->files[data->nFiles] = f; data->titles[data->nFiles++] = strdup(e->d_name); printf("%s\n", e->d_name); } } } closedir(dir); dir = opendir(curdir); while(e = readdir(dir)) { if (strcmp(e->d_name,".")==0) continue; printf("e->d_type=%d %d name=%s\n",e->d_type,DT_REG,e->d_name); if (e->d_type == DT_REG || e->d_type == DT_LNK) { if (data->nFiles < MAX_ENTRY) { f = fileinfo_new(); data->files[data->nFiles] = f; data->titles[data->nFiles++] = strdup(e->d_name); printf("%s\n", e->d_name); } } } closedir(dir); data->titles[data->nFiles] = NULL; mb_animated_menu_set_titles(data->m,data->titles); } MyApp_InitContent(char *dir) { app_data_t *data = MBAF_DATA(app,app_data_t); subject_t *key = MBAF_KB_SUBJECT(app); char name[255]; coord_t *l; int i; mb_sprite_t *sprite=app->rootsprite; data->m = mb_animated_menu_new(app,app->rootsprite,"item",NULL); mb_animated_menu_set_callback(data->m, myselect); mb_animated_menu_set_update_callback(data->m, myupdate); data->curDir = NULL; data->nFiles=0; MyApp_fillDirInfo(app,dir); mb_animated_menu_set_speed(data->m,300); } int main(int argc, char * const argv[]) { subject_t *subject; mb_obj_t *button; app_data_t data; mb_timeval_t tmo,interval; char *dir; if (argc > 1) dir = argv[1]; else dir ="/tmp"; app = mbaf_init("browser", ".libs"); mbaf_set_data(app,&data); MyApp_InitContent(dir); mbaf_loop(app); return 0; } /* vim: set ts=4 */
