Detailed Description

Input iterator used to iterate over all the widgets in a form.

This class is mainly used by templates to render widgets. It recursively iterates over all the widgets and subforms.

Note

it iterates over widgets only and never form objects.

iterator p=f.begin();
if(p!=f.end())
  if p!=f.end() --> *p is derived from widgets::base_widget.

Constructor & Destructor Documentation

cppcms::form::iterator::iterator

(

)

End iterator.

cppcms::form::iterator::iterator

(

form &

)

Create a widget iterator.

cppcms::form::iterator::~iterator

(

)

Destructor.

cppcms::form::iterator::iterator

(

iterator const &

other

)

Copy the iterator. This operation is not cheap.

Member Function Documentation

bool cppcms::form::iterator::operator!= ( iterator const &  other ) const

inline

Check if two iterators point to different elements.

widgets::base_widget& cppcms::form::iterator::operator* ( ) const

inline

Return the underlying widget. Condition: *this!=iterator().

iterator cppcms::form::iterator::operator++ ( int  )

inline

Post increment operator. It forwards the iterator to the next widget. Note it does not point to the higher level form container.

Note: it is preferable to use ++i rather than i++ as copying iterators is not cheap.

iterator& cppcms::form::iterator::operator++ ( )

inline

Increment operator. It forwards the iterator to the next widget. Note it does not point to the higher level form container.

widgets::base_widget* cppcms::form::iterator::operator-> ( ) const

inline

Return the underlying widget. Condition: *this!=iterator().

iterator const& cppcms::form::iterator::operator=

(

iterator const &

other

)

Assign the iterator. This operation is not cheap.

bool cppcms::form::iterator::operator== ( iterator const &  other ) const

inline

Check if two iterators point to the same element.
