function.
orientation
represents direction and can create curtain widgets in five different directions: up, down, left, right, and center.
Scope

typedef enum
{
CURTAIN_UNDEFINED,
CURTAIN_UP,
CURTAIN_DOWN,
CURTAIN_LEFT,
CURTAIN_RIGHT,
CURTAIN_MIDDLE,
} T_GUI_CURTAIN_ENUM;

gui_curtain_t *ct_clock = gui_curtain_create(ct, "1", 0, 0, 368, 448, CURTAIN_MIDDLE, 1);
gui_curtain_t *ct_control0 = gui_curtain_create(ct, "2", 0, 0, 368, 448, CURTAIN_UP, 1);
gui_curtain_t *ct_left = gui_curtain_create(ct, "3", 0, 0, 368, 448, CURTAIN_LEFT, 0.65f);
gui_curtain_t *ct_card = gui_curtain_create(ct, "card", 0, 0, 368, 448, CURTAIN_DOWN, 1);
