Detailed Description

Macro Definition Documentation

n_GRect

#define n_GRect	(		x,
			y,
			w,
			h
	)		((n_GRect) {{x, y}, {w, h}})

Convenience macro to quickly define a rectangle.

n_grect_standardize

#define n_grect_standardize

(

a

)

Value:

((a).size.w >= 0 \
        ? (a).size.h >= 0 \
            /* normal */ \
            ? (n_GRect) { {  (a).origin.x,      (a).origin.y }, \
                          {  (a).size.w,        (a).size.h     }} \
            /* switch vertically */ \
            : (n_GRect) { {  (a).origin.x,      (a).origin.y + (a).size.h - 1 }, \
                          {  (a).size.w,       -(a).size.h + 2 }} \
        : (a).size.h >= 0 \
            /* switch horizontally */ \
            ? (n_GRect) { {  (a).origin.x + (a).size.w - 1, (a).origin.y }, \
                          { -(a).size.w + 2,    (a).size.h     }} \
            /* switch horizontally and vertically */ \
            : (n_GRect) { {  (a).origin.x + (a).size.w - 1, (a).origin.y + (a).size.h - 1 }, \
                          { -(a).size.w + 2,   -(a).size.h + 2 }})

Convenience macro to standardize a rectangle.

Warning

Differs from the Pebble OS implementation, which is in-place and takes a pointer.
