Gtk.BitsetIter¶

record (struct)

Iterates over the elements of a Bitset.

`GtkBitSetIter is an opaque, stack-allocated struct.

Before a GtkBitsetIter can be used, it needs to be initialized with BitsetIter.init_first, BitsetIter.init_last or BitsetIter.init_at.

Methods¶

def get_value(self) -> int

Gets the current value that iter points to.

If iter is not valid and BitsetIter.is_valid returns False, this function returns 0.

def is_valid(self) -> bool

Checks if iter points to a valid value.

def next(self) -> tuple[bool, int]

Moves iter to the next value in the set.

If it was already pointing to the last value in the set, False is returned and iter is invalidated.

def previous(self) -> tuple[bool, int]

Moves iter to the previous value in the set.

If it was already pointing to the first value in the set, False is returned and iter is invalidated.

@staticmethod
def init_at(set: Bitset, target: int) -> tuple[bool, BitsetIter, int]

Initializes iter to point to target.

If target is not found, finds the next value after it. If no value >= target exists in set, this function returns False.

Parameters:

@staticmethod
def init_first(set: Bitset) -> tuple[bool, BitsetIter, int]

Initializes an iterator for set and points it to the first value in set.

If set is empty, False is returned and value is set to G_MAXUINT.

Parameters:

@staticmethod
def init_last(set: Bitset) -> tuple[bool, BitsetIter, int]

Initializes an iterator for set and points it to the last value in set.

If set is empty, False is returned.

Parameters:

private_data: list[int]  # read/write
