The class structure for IpuzCrosswords.

Class members

parent_class: IpuzGridClass

The grid class structure representing the parent.

fix_symmetry: void (* fix_symmetry) ( IpuzCrossword* self, IpuzSymmetry symmetry, GArray* symmetry_coords )

Vfunc that enforces the board symmetry of the cells in summetry_coords in the direction of symmetry.

fix_numbering: void (* fix_numbering) ( IpuzCrossword* self )

Vfunc that goes through all the normal cells in the grid and calculates the numbers for clues. This will clear any existing numbers or labels associated with cells.

fix_clues: void (* fix_clues) ( IpuzCrossword* self )

Vfunc that ensures that there are IpuzClues for every sequenctial run of across or down normal cells of two or more. This will potentially add or remove existing clues as necessary.

fix_enumerations: void (* fix_enumerations) ( IpuzCrossword* self )

Vfunc that ensures that every clue has an enumeration if IpuzCrossword:show-enumerations is set to TRUE. If not set already set, an enumeration the apparent length of the clue will be created.

fix_styles: void (* fix_styles) ( IpuzCrossword* self )

Vfunc that clears empty IpuzStyles from all the cells.

fix_all_valist: void (* fix_all_valist) ( IpuzCrossword* self, va_list var_args )

Convenience vfunc for calling all the _fix() functions in crosswords sequentially. This is not available for language bindings.

clue_continues_up: gboolean (* clue_continues_up) ( IpuzCrossword* self, const IpuzCellCoord* coord )

Vfunc that returns TRUE if the down clue crossing coord can be continued up.

clue_continues_down: gboolean (* clue_continues_down) ( IpuzCrossword* self, const IpuzCellCoord* coord )

Vfunc that returns TRUE if the down clue crossing coord can be continued down.

clue_continues_left: gboolean (* clue_continues_left) ( IpuzCrossword* self, const IpuzCellCoord* coord )

Vfunc that returns TRUE if the down clue crossing coord can be continued left.

clue_continues_right: gboolean (* clue_continues_right) ( IpuzCrossword* self, const IpuzCellCoord* coord )

Vfunc that returns TRUE if the down clue crossing coord can be continued right.

mirror_cell: void (* mirror_cell) ( IpuzCrossword* self, const IpuzCellCoord* src_coord, const IpuzCellCoord* dest_coord, IpuzSymmetry symmetry, IpuzSymmetryOffset symmetry_offset )

Vfunc that makes the cell at dest_coord match the appearance of the cell at src_coord while maintaining symmetry.

check_mirror: gboolean (* check_mirror) ( IpuzCrossword* self, const IpuzCellCoord* src_coord, const IpuzCellCoord* dest_coord, IpuzSymmetry symmetry, IpuzSymmetryOffset symmetry_offset )

Vfunc that checks the cell at dest_coord to see if it’s the symmetric opposite of the cell at src_coord.
