(Rectangle)->x = X; \ (Rectangle)->y = Y; \ (Rectangle)->w = W; \ (Rectangle)->h = H;
Macro to set the values of a Eina_Rectangle.
- Parameters:
-
Rectangle The rectangle to set the values. X The X coordinate of the top left corner of the rectangle. Y The Y coordinate of the top left corner of the rectangle. W The width of the rectangle. H The height of the rectangle.
This macro set the values of Rectangle
. (X
, Y
) is the coordinates of the top left corner of Rectangle
, W
is its width and H
is its height.
Function Documentation
EAPI Eina_Rectangle_Pool* eina_rectangle_pool_get | ( | Eina_Rectangle * | rect | ) |
Return the pool of the given rectangle.
- Parameters:
-
rect The rectangle.
- Returns:
- The pool of the given rectangle.
This function returns the pool in which rect
is. If rect
is NULL
, NULL
is returned.
EAPI Eina_Bool eina_rectangle_pool_geometry_get | ( | Eina_Rectangle_Pool * | pool, | |
int * | w, | |||
int * | h | |||
) |
Return the width and height of the given pool.
- Parameters:
-
pool The pool. w The returned width. h The returned height.
- Returns:
- EINA_TRUE on sucess, EINA_FALSE otherwise.
This function returns the width and height of pool
and store them in respectively w
and h
if they are not NULL
. If pool
is NULL
, EINA_FALSE is returned. Otherwise EINA_TRUE is returned.
EAPI void* eina_rectangle_pool_data_get | ( | Eina_Rectangle_Pool * | pool | ) |
Get the data from the given pool.
- Parameters:
-
pool The pool.
- Returns:
- The returned data.
This function gets the data from pool
set by eina_rectangle_pool_data_set(). If pool
is NULL
, this function returns NULL
.
EAPI void eina_rectangle_pool_data_set | ( | Eina_Rectangle_Pool * | pool, | |
const void * | data | |||
) |
Set the data to the given pool.
- Parameters:
-
pool The pool. data The data to set.
This function sets data
to pool
. If pool
is NULL
, this function does nothing.
EAPI int eina_rectangle_pool_count | ( | Eina_Rectangle_Pool * | pool | ) |
Return the number of rectangles in the given pool.
- Parameters:
-
pool The pool.
- Returns:
- The number of rectangles in the pool.
This function returns the number of rectangles in pool
.
EAPI Eina_Rectangle* eina_rectangle_new | ( | int | x, | |
int | y, | |||
int | w, | |||
int | h | |||
) |
Create a new rectangle.
- Parameters:
-
x The X coordinate of the top left corner of the rectangle. y The Y coordinate of the top left corner of the rectangle. w The width of the rectangle. h The height of the rectangle.
- Returns:
- The new rectangle on success, @ NULL otherwise.
This function creates a rectangle which top left corner has the coordinates (x
, y
), with height w
and height h
and adds it to the rectangles pool. No check is done on w
and h
. This function returns a new rectangle on success, NULL
otherwhise.
EAPI void eina_rectangle_free | ( | Eina_Rectangle * | rect | ) |
Free the given rectangle.
- Parameters:
-
rect The rectangle to free.
This function removes rect
from the rectangles pool.
