VariantIter - An opaque data structure used to iterate through VariantContainerBase containers such as arrays. 
- Since glibmm 2.28:
◆ VariantIter() [1/5]
      
        
          | Glib::VariantIter::VariantIter | ( |  | ) |  | 
      
 
Constructs an invalid object. 
E.g. for output arguments to methods. There is not much you can do with the object before it has been assigned a valid value. 
 
 
◆ VariantIter() [2/5]
◆ VariantIter() [3/5]
◆ VariantIter() [4/5]
◆ ~VariantIter()
  
  | 
        
          | Glib::VariantIter::~VariantIter | ( |  | ) |  |  | noexcept | 
 
 
◆ VariantIter() [5/5]
◆ get_n_children()
      
        
          | gsize Glib::VariantIter::get_n_children | ( |  | ) | const | 
      
 
Queries the number of child items in the container that we are iterating over. 
This is the total number of items – not the number of items remaining.
This function might be useful for preallocation of arrays.
- Since glibmm 2.24:
- Returns
- The number of children in the container. 
 
 
◆ gobj() [1/2]
◆ gobj() [2/2]
◆ gobj_copy()
Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs. 
 
 
◆ init()
Initialises (without allocating) a VariantIter. 
iter may be completely uninitialised prior to this call; its old value is ignored.
The iterator remains valid for as long as value exists, and need not be freed in any way.
- Since glibmm 2.24:
- Parameters
- 
  
  
- Returns
- The number of items in value. 
 
 
◆ next_value()
      
        
          | bool Glib::VariantIter::next_value | ( | VariantBase & | value | ) |  | 
      
 
 
◆ operator=() [1/2]
◆ operator=() [2/2]
◆ swap()
◆ swap()
- Parameters
- 
  
    | lhs | The left-hand side |  | rhs | The right-hand side |  
 
 
 
◆ wrap()
A Glib::wrap() method for this object. 
- Parameters
- 
  
    | object | The C instance. |  | take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref. |  
 
- Returns
- A C++ instance that wraps this C instance.
