The container manager manages overlapping of views and their life time based on their type
and scope. Performs loading of views through the specified loader.
1. Overlapping of views
UI consists of several layers. Each layer has its own Z index. It allows to control overlapping
of views (views of the top level layer overlap views of underlying layers). The set of default
layers depends on entry (application) type (lobby and battle have their own configuration).
Each view can belong to one layer and it is defined by view's type. With each layer associated
one view container that is managed by the container manager. There are two types of layers
(view containers):
- DefaultContainer - only one top level view can be placed in the container (layer) and if a
new view is placed to it the previous one is destroyed;
- PopUpContainer - several views can exist at the same time in one layer.
Also any top level view can include a subview that is placed into a sub-container. If a top
level view can include a sub-view, the sub-container is created after the top level view is loaded and
initialized. When sub-view is loaded, it is placed into the top level view's sub-container. The sub-container
is destroyed when the top level view is destroyed.
2. Views life time
The 'view scope' concept is introduced to simplify views lifetime management. View lifetime is
defined by its scope and is controlled by the container manager through the scope controller.
View scope defines when the view should be destroyed: if the parent view (parent scope) is
destroyed, the subview is destroyed too. For details please see ScopeController description.
