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.

Provides access to the underlying C instance. The caller is responsible for freeing it. Use when directly setting fields in structs.
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.

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.
