Struct qt_gui::q_text_block::Iterator

#[repr(C)]
pub struct Iterator { /* private fields */ }

The QTextBlock::iterator class provides an iterator for reading the contents of a QTextBlock.

C++ class: QTextBlock::iterator.

C++ documentation:

The QTextBlock::iterator class provides an iterator for reading the contents of a QTextBlock.

A block consists of a sequence of text fragments. This class provides a way to iterate over these, and read their contents. It does not provide a way to modify the internal structure or contents of the block.

An iterator can be constructed and used to access the fragments within a text block in the following way:

      QTextBlock::iterator it;
      for (it = currentBlock.begin(); !(it.atEnd()); ++it) {
          QTextFragment currentFragment = it.fragment();
          if (currentFragment.isValid())
              processFragment(currentFragment);
      }

Implementations

impl Iterator

pub unsafe fn at_end(&self) -> bool

Returns true if the current item is the last item in the text block.

Calls C++ function: bool QTextBlock::iterator::atEnd() const.

C++ documentation:

Returns true if the current item is the last item in the text block.

pub unsafe fn copy_from( &self, other: impl CastInto<Ref<Iterator>> ) -> Ref<Iterator>

The QTextBlock::iterator class provides an iterator for reading the contents of a QTextBlock.

Calls C++ function: QTextBlock::iterator& QTextBlock::iterator::operator=(const QTextBlock::iterator& other).

          if (currentFragment.isValid())
              processFragment(currentFragment);
      }

pub unsafe fn dec(&self) -> Ref<Iterator>

The prefix -- operator (--i) makes the preceding item current and returns an iterator pointing to the new current item.

Calls C++ function: QTextBlock::iterator& QTextBlock::iterator::operator--().

C++ documentation:

The prefix – operator (–i) makes the preceding item current and returns an iterator pointing to the new current item.

pub unsafe fn dec_postfix(&self, arg1: c_int) -> CppBox<Iterator>

The postfix -- operator (i--) makes the preceding item current and returns an iterator to the old current item.

Calls C++ function: QTextBlock::iterator QTextBlock::iterator::operator--(int arg1).

C++ documentation:

The postfix – operator (i–) makes the preceding item current and returns an iterator to the old current item.

pub unsafe fn fragment(&self) -> CppBox<QTextFragment>

Returns the text fragment the iterator currently points to.

Calls C++ function: QTextFragment QTextBlock::iterator::fragment() const.

C++ documentation:

Returns the text fragment the iterator currently points to.

pub unsafe fn inc(&self) -> Ref<Iterator>

The prefix ++ operator (++i) advances the iterator to the next item in the hash and returns an iterator to the new current item.

Calls C++ function: QTextBlock::iterator& QTextBlock::iterator::operator++().

C++ documentation:

The prefix ++ operator (++i) advances the iterator to the next item in the hash and returns an iterator to the new current item.

pub unsafe fn inc_postfix(&self, arg1: c_int) -> CppBox<Iterator>

The postfix ++ operator (i++) advances the iterator to the next item in the text block and returns an iterator to the old current item.

Calls C++ function: QTextBlock::iterator QTextBlock::iterator::operator++(int arg1).

C++ documentation:

The postfix ++ operator (i++) advances the iterator to the next item in the text block and returns an iterator to the old current item.

pub unsafe fn new() -> CppBox<Iterator>

Constructs an iterator for this text block.

Calls C++ function: [constructor] void QTextBlock::iterator::iterator().

C++ documentation:

Constructs an iterator for this text block.

pub unsafe fn new_copy(o: impl CastInto<Ref<Iterator>>) -> CppBox<Iterator>

Copy constructor. Constructs a copy of the other iterator.

Calls C++ function: [constructor] void QTextBlock::iterator::iterator(const QTextBlock::iterator& o).

C++ documentation:

Copy constructor. Constructs a copy of the other iterator.

Trait Implementations

              processFragment(currentFragment);
      }

impl Decrement for Iterator

unsafe fn dec(&self) -> Ref<Iterator>

The prefix -- operator (--i) makes the preceding item current and returns an iterator pointing to the new current item.

Calls C++ function: QTextBlock::iterator& QTextBlock::iterator::operator--().

C++ documentation:

The prefix – operator (–i) makes the preceding item current and returns an iterator pointing to the new current item.

type Output = Ref<Iterator>

Output type.

impl Increment for Iterator

unsafe fn inc(&self) -> Ref<Iterator>

The prefix ++ operator (++i) advances the iterator to the next item in the hash and returns an iterator to the new current item.

Calls C++ function: QTextBlock::iterator& QTextBlock::iterator::operator++().

C++ documentation:

The prefix ++ operator (++i) advances the iterator to the next item in the hash and returns an iterator to the new current item.

type Output = Ref<Iterator>

Output type.

impl PartialEq<Ref<Iterator>> for Iterator

fn eq(&self, o: &Ref<Iterator>) -> bool

Retuns true if this iterator is the same as the other iterator; otherwise returns false.

Calls C++ function: bool QTextBlock::iterator::operator==(const QTextBlock::iterator& o) const.

C++ documentation:

Retuns true if this iterator is the same as the other iterator; otherwise returns false.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
