Declaration [src]

GArray*
ipuz_nonogram_get_clues (
  IpuzNonogram* self,
  guint index,
  IpuzClueDirection direction
)

Description [src]

Returns an array containing the run of IpuzNonogramClue indicated by index and direction.

As an example, consider the second row of the example at IpuzNonogram:

Nonogram row

It will be represented by an array with four IpuzNonogramClue structs. The count of the clues will be [5, 4, 3, 3], and the group of all four clues will be IpuzPuzzle:block.

GArray *row;
IpuzNonogramClue clue_segment;

row = ipuz_nonogram_get_clues (nonogram, 1, IPUZ_CLUE_DIRECTION_ACROSS);
g_assert_cmpint (row->len, ==, 4);

clue_segment = g_array_index (row, IpuzNonogramClue, 2);
g_assert_cmping (clue_segment.index, ==, 3);
g_assert_cmpstr (clue_segment.group, ==,
                 ipuz_puzzle_get_block (IPUZ_PUZZLE (nonogram)));

Note

This function will return an empty array — and not NULL — if the puzzle has no blocks in the indicated row or column.
