Graphic interface

Using Arduino Programming Questions
1

hello, i'm beginner, i'm doing an graphic interface ( arduino screen). i'm trying now to do basic tests, for now i would like to display the home menu (principal menu) with it's items.
i'm having problem in the code, propoply the acces to the structere, any help ?
typedef enum {
IDM_MAIN=0,

typedef struct

typedef struct {

}t_PAGE;

void displayMenu_task(void)
{

}

You can't initialize a pointer to a structure with a list of structure initializers. Use an array of structures instead:

t_PAGE pscreenMenu[] =
{
  //{ enum page, page_title, enum parent_page,{ { item1,func1 },{ item2, func2 } }, Itemsize },
  //0
  { IDM_MAIN, "PRINCIPAL MENU", IDM_MAIN, { {IDM_FIX_MODE}, {IDM_MOBILE_MODE} }, 2 }, // t-page1

yes actually i tried that, but it doesn't work, i did like that, is it right ?

typedef enum {
IDM_MAIN=0,
IDM_FIX_MODE,
IDM_MOBILE_MODE,
IDM_LAST_SETTING,
IDM_POSITION=11,
IDM_RESET,
IDM_YOUR_COORDINATES=21,
IDM_APPLY_LAST_SETTING=31,
IDM_OLD_POSITION=111,
IDM_NEW_POSITION,
IDM_APPLY_RESET=121,
IDM_LAST_SETTING_CONFIRMED=131,
IDM_APPLY_OLD_POSITION=1111,
IDM_NAME=2111,
IDM_X,
IDM_Y,
IDM_Z,
IDM_RESET_CONFIRMED = 1211,
IDM_OLD_POSITION_CONFIRMED = 11111
}IDM_page;

typedef struct
{
IDM_page next_page;
void function(void);
}t_ITEM_MODE;

typedef struct {
IDM_page page;
char page_title[20];
IDM_page parent_page;
t_ITEM_MODE item[10];
int ItemsSize;

}t_PAGE;

t_PAGE screenMenu[] = {

//{ enum page, page_title[], enum parent_page,{ { item1,func1 },{ item2, func2 } }, Itemsize },
//0
{ IDM_MAIN, "PRINCIPAL MENU", IDM_MAIN, { {IDM_FIX_MODE},{IDM_MOBILE_MODE} }, 2 }, // t-page1
//
{ IDM_FIX_MODE,"FIXE MODE",IDM_MAIN, { {IDM_POSITION},{IDM_RESET} }, 2 }, // t_page2
{ IDM_MOBILE_MODE,"MOBLIE MODE",IDM_MAIN, { {IDM_YOUR_COORDINATES} }, 1 },
{ IDM_LAST_SETTING,"LAST SETTING",IDM_MAIN,{ {IDM_APPLY_LAST_SETTING} }, 1 },
{ IDM_OLD_POSITION_CONFIRMED, "OLD_POSITION", IDM_OLD_POSITION }
};

in the cpp file :

void SCREEN::displayMenu_funct(t_PAGE screenMenu[], int ItemCurrent , int ItemMini, int ItemMax)
{
int n=0;
u8g2.firstPage();
do {
u8g2.setFont(u8g2_font_ncenB10_tr);
u8g2.drawStr(32,8,*screenMenu[0]->page_title);
}while ( u8g2.nextPage() );
}

void SCREEN :: displayMenu_task(void)
{
displayMenu_funct(*screenMenu[0], ItemCurrent, ItemMini, ItemMax);
}

in the prog.ino file :

screen.displayMenu_task();

I can't tell. it is not a complete sketch and it appears to use unspecified libraries.

yes i just would like to know, if i want to acces to a specific structure in my array of structure, for exemple the first structure is it like that ?

displayMenu_funct(screenMenu[0]);
/**************************************/
void SCREEN::displayMenu_funct(t_PAGE screenMenu[])
{
u8g2.drawStr(32,8,screenMenu[0].page_title);
}

Since the 't_PAGE' you pass is a struct, not an array of structs, you would not use an array index:

`u8g2.drawStr(32,8,screenMenu.page_title);'

It gets a little confusing because your global array of structs and the function argument are both called 'screenMenu'. It might be easier if you change the function argument to 'menuPage'.
