Detailed Description

template<class T, class R, typename I, I(T::*)() const Count, R *(T::*)(I) const Access>
class ml::ContainerProxy< T, R, I, Count, Access >

This template implements a proxy for containers that contain a collection of items normally accessed with a get-by-index method.

Due to this structure, it is not possible to use them in any STL-compatible algorithm or range-based for-loop. This way, the proxy provides a begin()/end() pair that follows the standard STL conventions. Note that calling *end() is not advisable.

By defining a proxy like:

   using TreeWidgetProxy = ContainerHelpers::ContainerProxy<QTreeWidget,
                                                             QTreeWidgetItem,
                                                             int,
                                                             &QTreeWidget::topLevelItemCount,
                                                             &QTreeWidget::topLevelItem>;
auto element = SCR::in(TreeWidgetProxy(*myListView)).find([&value](QTreeWidgetItem* item)
  { return item->text(0) == value; }).or_return_nullptr();

Note: It is not wise to add or remove items within any loop!
