@class wxDocument
The document class can be used to model an application's file-based data.
+
It is part of the document/view framework supported by wxWidgets, and
cooperates with the wxView, wxDocTemplate and wxDocManager classes.
+ A normal document is the one created without parent document and is
+ associated with a disk file. Since version 2.9.2 wxWidgets also supports a
+ special kind of documents called child documents which are virtual
+ in the sense that they do not correspond to a file but rather to a part of
+ their parent document. Because of this, the child documents can't be
+ created directly by user but can only be created by the parent document
+ (usually when it's being created itself). They also can't be independently
+ saved. A child document has its own view with the corresponding window.
+ This view can be closed by user but, importantly, is also automatically
+ closed when its parent document is closed. Thus, child documents may be
+ convenient for creating additional windows which need to be closed when the
+ main document is. The docview sample demonstrates this use of child
+ documents by creating a child document containing the information about the
+ parameters of the image opened in the main document.
