Constructs an identifiable object from a list of components, in a declarative fashion.

Constructs an identifiable object from a list of components, in a declarative fashion.

Parameters

id	[OUTPUT] A pointer to an LCD_ObjID variable, where the ID of the object will be stored. This ID can be used to remove the object from the list, or to update it. You can specify NULL if you don't need the ID (in that case just use the LCD_RENDER_IMM!)
...	The components that make up the object.

LCD_ObjID id; LCD_Error err = LCD_OBJECT(&id, { LCD_RECT(pos_rect, { .width = 10, .height = 10, .fill_color = LCD_COL_RED, }), LCD_TEXT(pos_text, { .text = "Hello, World!", .font = LCD_DEF_FONT_SYSTEM, .text_color = LCD_COL_BLUE, }), });

if (err != LCD_ERR_OK) LCD_RMRender();

Note

Since the objects are identifiable, they need space in the memory arena specified during the initialization of the LCD module. If the memory arena is full, the function will return the error.

Returns

The LCD_Error that LCD_RMAdd returns.
