class layer_iterator

A special iterator that mimics the interface of the standard iterator but the increment and decrement operators move by sibling.

Public Methods

void next()

steps to the next sibling

void previous()

steps to the previous sibling

void next_sibling()

steps over this items's children to its next sibling

void previous_sibling()

steps over the previous item's children, to the previous sibling

void first_child()

steps to this item's first child

void last_child()

steps to this item's last child

void up_to_parent()

steps up to this item's parent

bool has_children()

Returns true if this widget has children

T& get_data()

Returns the item at this iterator

const T& get_data() const

Returns the item at this iterator

layer_iterator& operator++ ()

steps to the next sibling

layer_iterator& operator-- ()

steps to the previous sibling

layer_iterator operator++ (int)

steps to the next sibling

layer_iterator operator-- (int)

steps to the previous sibling

T& operator* ()

Returns the item at this iterator

const T& operator* () const

Returns the item at this iterator

bool operator!= (const layer_iterator& _other) const

Returns false if the iterators point to the same widget

bool operator== (const layer_iterator& _other) const

Returns true is the iterators point to the same object

layer_iterator& operator= (const layer_iterator& V)

Assign this iterator to the value of another

Documentation

A special iterator that mimics the interface of the standard iterator but the increment and decrement operators move by sibling. The only way to access the children is but using the first_child and last_child functions.
