- add bMenu.c and bMenu.h to your project .
- calling bM_Init() function. add malloc and free interface
- building your menu structure
item1----item2-----item3-----item4
|
item5----item6----item7
|
item8--item9
|
item10
it's a four levels menu. then, divide it:
create four objects by bM_CreateObject();
add items and creating UI function to the object by bM_AddItemToObject();
object1 {item1----item2----item3----item4}
object2 {item5----item6----item7}
object3 {item8----item9}
object4 {item10}
user_id of every object and item must be different.
maybe you can do that through enum:
enum
{
USER_ID_OBJECT_1,
USER_ID_ITEM1,
USER_ID_ITEM2,
USER_ID_ITME3,
USER_ID_ITEM4,
USER_ID_OBJECT_2,
USER_ID_ITEM5,
USER_ID_ITEM6,
USER_ID_ITEM7,
USER_ID_OBJECT_3,
USER_ID_ITEM8,
USER_ID_ITEM9,
USER_ID_OBJECT_4,
USER_ID_ITEM10
};
example_func
{
bM_OBJ_Handle hobj, hobj_tmp;
bM_ITEM_Handle hItem;
hobj = bM_CreateObject(bM_HANDLE_INVALID, USER_ID_OBJECT_1);
bM_AddItemToObject(hobj, USER_ID_ITEM1, func1);
hItem = bM_AddItemToObject(hobj, USER_ID_ITEM2, func2);
bM_AddItemToObject(hobj, USER_ID_ITME3, func3);
bM_AddItemToObject(hobj, USER_ID_ITEM4, func4);
hobj_tmp = bM_CreateObject(hItem, USER_ID_OBJECT_2);
bM_AddItemToObject(hobj_tmp, USER_ID_ITEM5, func5);
hItem = bM_AddItemToObject(hobj_tmp, USER_ID_ITEM6, func6);
bM_AddItemToObject(hobj_tmp, USER_ID_ITEM7, func7);
hobj_tmp = bM_CreateObject(hItem, USER_ID_OBJECT_3);
hItem = bM_AddItemToObject(hobj_tmp, USER_ID_ITEM8, func8);
bM_AddItemToObject(hobj_tmp, USER_ID_ITEM9, func9);
hobj_tmp = bM_CreateObject(hItem, USER_ID_OBJECT_4);
bM_AddItemToObject(hobj_tmp, USER_ID_ITEM10, func10);
//then set the entry point:
bM_SetMenuEntryPoint(hobj);
}then the menu structure has been created.
add bM_BMenuModuleTask() to while(1)
then:
you can call bM_SendMessage() to control switching.
for example:
bM_SendMessage(BM_OPERATE_NEXT, 0); // to show the next item
bM_SendMessage(BM_OPERATE_JUMP_TO, USER_ID_ITEM5); //to show the item5Ok! you can try it by yourself now!
if you have some suggestion, please contact me.
