+@page overview_docview Document/View Framework
+
+@tableofcontents
+
+The document/view framework is found in most application frameworks, because it
+can dramatically simplify the code required to build many kinds of application.
+
+The idea is that you can model your application primarily in terms of
+@e documents to store data and provide interface-independent operations upon
+it, and @e views to visualise and manipulate the data. Documents know how to do
+input and output given stream objects, and views are responsible for taking
+input from physical windows and performing the manipulation on the document
+data.
+
+If a document's data changes, all views should be updated to reflect the
+change. The framework can provide many user-interface elements based on this
+model.
+
+Once you have defined your own classes and the relationships between them, the
+framework takes care of popping up file selectors, opening and closing files,
+asking the user to save modifications, routing menu commands to appropriate
+(possibly default) code, even some default print/preview functionality and
+support for command undo/redo.
+
+The framework is highly modular, allowing overriding and replacement of
+functionality and objects to achieve more than the default behaviour.
+
+These are the overall steps involved in creating an application based on the
+document/view framework:
+
+@li Define your own document and view classes, overriding a minimal set of
+    member functions e.g. for input/output, drawing and initialization.
+@li Define any subwindows (such as a scrolled window) that are needed for the
+    view(s). You may need to route some events to views or documents, for
+    example, "OnPaint" needs to be routed to wxView::OnDraw.
+@li Decide what style of interface you will use: Microsoft's MDI (multiple
+    document child frames surrounded by an overall frame), SDI (a separate,
+    unconstrained frame for each document), or single-window (one document open
+    at a time, as in Windows Write).
+@li Use the appropriate wxDocParentFrame and wxDocChildFrame classes. Construct
+    an instance of wxDocParentFrame in your wxApp::OnInit, and a
+    wxDocChildFrame (if not single-window) when you initialize a view. Create
+    menus using standard menu ids (such as wxID_OPEN, wxID_PRINT).
+@li Construct a single wxDocManager instance at the beginning of your
+    wxApp::OnInit, and then as many wxDocTemplate instances as necessary to
+    define relationships between documents and views. For a simple application,
+    there will be just one wxDocTemplate.

+the view menu.

 
 

- These are the overall steps involved in creating an application based on the 
- document/view framework:
+Here are a few examples of the tailoring you can do to go beyond the default
+framework behaviour:
+
+@li Override wxDocument::OnCreateCommandProcessor to define a different Do/Undo
+    strategy, or a command history editor.
+@li Override wxView::OnCreatePrintout to create an instance of a derived
+    wxPrintout class, to provide multi-page document facilities.
+@li Override wxDocManager::SelectDocumentPath to provide a different file
+    selector.
+@li Limit the maximum number of open documents and the maximum number of undo
+    commands.
+
+Note that to activate framework functionality, you need to use some or all of
+the wxWidgets @ref overview_docview_predefid in your menus.
+
+@beginWxPerlOnly
+The document/view framework is available in wxPerl. To use it, you will need
+the following statements in your application code:
+
+@code{.pl}
+use Wx::DocView;
+use Wx ':docview';   # import constants (optional)
+@endcode
+@endWxPerlOnly
+
+@see @ref group_class_docview, 
+
+
+
+@section overview_docview_wxdoc wxDocument Overview
+
+The wxDocument 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. Using this framework
+can save a lot of routine user-interface programming, since a range of menu
+commands -- such as open, save, save as -- are supported automatically.

 
 

- @li Define your own document and view classes, overriding a minimal set of
-     member functions e.g. for input/output, drawing and initialization.
- @li Define any subwindows (such as a scrolled window) that are needed for the view(s).
-     You may need to route some events to views or documents, for example OnPaint needs 
-     to be routed to wxView::OnDraw.
- @li Decide what style of interface you will use: Microsoft's MDI (multiple
-     document child frames surrounded by an overall frame), SDI (a separate, unconstrained frame
-     for each document), or single-window (one document open at a time, as in Windows Write).
- @li Use the appropriate wxDocParentFrame and wxDocChildFrame classes. Construct an instance
-     of wxDocParentFrame in your wxApp::OnInit, and a wxDocChildFrame (if not single-window) when
-     you initialize a view. Create menus using standard menu ids (such as wxID_OPEN, wxID_PRINT).
- @li Construct a single wxDocManager instance at the beginning of your wxApp::OnInit, and then
-     as many wxDocTemplate instances as necessary to define relationships between documents and
-     views. For a simple application, there will be just one wxDocTemplate.
+The programmer just needs to define a minimal set of classes and member
+functions for the framework to call when necessary. Data, and the means to view
+and edit the data, are explicitly separated out in this model, and the concept
+of multiple @e views onto the same data is supported.

 
 

- If you wish to implement Undo/Redo, you need to derive your own class(es) from wxCommand
- and use wxCommandProcessor::Submit instead of directly executing code. The framework will
- take care of calling Undo and Do functions as appropriate, so long as the wxID_UNDO and
- wxID_REDO menu items are defined in the view menu.
+Note that the document/view model will suit many but not all styles of
+application. For example, it would be overkill for a simple file conversion
+utility, where there may be no call for @e views on @e documents or the ability
+to open, edit and save files. But probably the majority of applications are
+document-based.

 
 

- Here are a few examples of the tailoring you can do to go beyond the default framework
- behaviour:
+See the example application in @c samples/docview. To use the abstract
+wxDocument class, you need to derive a new class and override at least the
+member functions SaveObject and LoadObject. SaveObject and LoadObject will be
+called by the framework when the document needs to be saved or loaded.

 
 

- @li Override wxDocument::OnCreateCommandProcessor to define a different Do/Undo strategy,
-     or a command history editor.
- @li Override wxView::OnCreatePrintout to create an instance of a derived wxPrintout
-     class, to provide multi-page document facilities.
- @li Override wxDocManager::SelectDocumentPath to provide a different file selector.
- @li Limit the maximum number of open documents and the maximum number of undo commands.
+Use the macros DECLARE_DYNAMIC_CLASS and IMPLEMENT_DYNAMIC_CLASS in order to
+allow the framework to create document objects on demand. When you create a
+wxDocTemplate object on application initialization, you should pass
+CLASSINFO(YourDocumentClass) to the wxDocTemplate constructor so that it knows
+how to create an instance of this class.

 
 

- Note that to activate framework functionality, you need to use some or all of
- the wxWidgets @ref overview_docview_predefid in your menus.
+If you do not wish to use the wxWidgets method of creating document objects
+dynamically, you must override wxDocTemplate::CreateDocument to return an
+instance of the appropriate class.
+
+
+
+@section overview_docview_wxview wxView Overview
+
+The wxView class can be used to model the viewing and editing component of an
+application's file-based data. It is part of the document/view framework
+supported by wxWidgets, and cooperates with the wxDocument, wxDocTemplate and
+wxDocManager classes.
+
+See the example application in @c samples/docview.
+
+To use the abstract wxView class, you need to derive a new class and override
+at least the member functions OnCreate, OnDraw, OnUpdate and OnClose. You will
+probably want to respond to menu commands from the frame containing the view.
+
+Use the macros DECLARE_DYNAMIC_CLASS and IMPLEMENT_DYNAMIC_CLASS in order to
+allow the framework to create view objects on demand. When you create a
+wxDocTemplate object on application initialization, you should pass
+CLASSINFO(YourViewClass) to the wxDocTemplate constructor so that it knows how
+to create an instance of this class.

+@section overview_docview_wxdoctemplate wxDocTemplate Overview

 
 

- <hr>
+The wxDocTemplate class is used to model the relationship between a document
+class and a view class. The application creates a document template object for
+each document/view pair. The list of document templates managed by the
+wxDocManager instance is used to create documents and views. Each document
+template knows what file filters and default extension are appropriate for a
+document/view combination, and how to create a document or view.

 
 

+For example, you might write a small doodling application that can load and
+save lists of line segments. If you had two views of the data -- graphical, and
+a list of the segments -- then you would create one document class
+DoodleDocument, and two view classes (DoodleGraphicView and DoodleListView).
+You would also need two document templates, one for the graphical view and
+another for the list view. You would pass the same document class and default
+file extension to both document templates, but each would be passed a different
+view class. When the user clicks on the Open menu item, the file selector is
+displayed with a list of possible file filters -- one for each wxDocTemplate.
+Selecting the filter selects the wxDocTemplate, and when a file is selected,
+that template will be used for creating a document and view.

 
 

- @section overview_docview_wxdoc wxDocument overview
+For the case where an application has one document type and one view type,
+a single document template is constructed, and dialogs will be appropriately
+simplified.

 
 

- Class: wxDocument
+wxDocTemplate is part of the document/view framework supported by wxWidgets,
+and cooperates with the wxView, wxDocument and wxDocManager classes.

 
 

- The wxDocument class can be used to model an application's file-based
- data. It is part of the document/view framework supported by wxWidgets,

- the data, are explicitly separated out in this model, and the concept of multiple
- @e views onto the same data is supported.
+To use the wxDocTemplate class, you do not need to derive a new class. Just
+pass relevant information to the constructor including
+CLASSINFO(YourDocumentClass) and CLASSINFO(YourViewClass) to allow dynamic
+instance creation.

 
 

- Note that the document/view model will suit many but not all styles of application.
- For example, it would be overkill for a simple file conversion utility, where there
- may be no call for @e views on @e documents or the ability to open, edit and save
- files. But probably the majority of applications are document-based.
+If you do not wish to use the wxWidgets method of creating document
+objects dynamically, you must override wxDocTemplate::CreateDocument

+@section overview_docview_wxdocmanager wxDocManager Overview

 
 

+The wxDocManager class is part of the document/view framework supported by
+wxWidgets, and cooperates with the wxView, wxDocument and wxDocTemplate
+classes.

 
 

- @section overview_docview_wxview wxView overview
+A wxDocManager instance coordinates documents, views and document templates. It
+keeps a list of document and template instances, and much functionality is
+routed through this object, such as providing selection and file dialogs. The
+application can use this class 'as is' or derive a class and override some
+members to extend or change the functionality.

 
 

- Class: wxView
+Create an instance of this class near the beginning of your application
+initialization, before any documents, views or templates are manipulated.

 
 

- The wxView class can be used to model the viewing and editing component of
- an application's file-based data. It is part of the document/view framework 
- supported by wxWidgets, and cooperates with the wxDocument, wxDocTemplate
- and wxDocManager classes.
+There may be multiple wxDocManager instances in an application. See the example
+application in @c samples/docview.

 
 

- See the example application in @c samples/docview.

 
 

- To use the abstract wxView class, you need to derive a new class and override
- at least the member functions OnCreate, OnDraw, OnUpdate and OnClose. You will probably
- want to respond to menu commands from the frame containing the view.
+@section overview_docview_events Event Propagation in Document/View framework

 
 

- Use the macros DECLARE_DYNAMIC_CLASS and IMPLEMENT_DYNAMIC_CLASS in order
- to allow the framework to create view objects on demand. When you create
- a wxDocTemplate object on application initialization, you
- should pass CLASSINFO(YourViewClass) to the wxDocTemplate constructor
- so that it knows how to create an instance of this class.
+While wxDocument, wxDocManager and wxView are abstract objects, with which the
+user can't interact directly, all of them derive from wxEvtHandler class and
+can handle events arising in the windows showing the document with which the
+user does interact. This is implemented by adding additional steps to the event
+handling process described in @ref overview_events_processing, so the full list
+of the handlers searched for an event occurring directly in wxDocChildFrame is:
+<ol>
+    <li>wxDocument opened in this frame.</li>
+    <li>wxView shown in this frame.</li>
+    <li>wxDocManager associated with the parent wxDocParentFrame.</li>
+    <li>wxDocChildFrame itself.</li>
+    <li>wxDocParentFrame, as per the usual event bubbling up to parent rules.</li>
+    <li>wxApp, again as the usual fallback for all events.</li>
+</ol>

 
 

- If you do not wish to use the wxWidgets method of creating view
- objects dynamically, you must override wxDocTemplate::CreateView
- to return an instance of the appropriate class.
+This is mostly useful to define handlers for some menu commands directly in
+wxDocument or wxView and is also used by the framework itself to define the
+handlers for several standard commands, such as wxID_NEW or wxID_SAVE, in
+wxDocManager itself. Notice that due to the order of the event handler search
+detailed above, the handling of these commands can @e not be overridden at
+wxDocParentFrame level but must be done at the level of wxDocManager itself.

 
 
 
 

+@section overview_docview_wxcommand wxCommand Overview

 
 

- @section overview_docview_wxdoctemplate wxDocTemplate overview
+wxCommand is a base class for modelling an application command, which is an
+action usually performed by selecting a menu item, pressing a toolbar button or
+any other means provided by the application to change the data or view.

 
 

- Class: wxDocTemplate
+Instead of the application functionality being scattered around switch
+statements and functions in a way that may be hard to read and maintain, the
+functionality for a command is explicitly represented as an object which can be
+manipulated by a framework or application.

 
 

- The wxDocTemplate class is used to model the relationship between a
- document class and a view class. The application creates a document
- template object for each document/view pair. The list of document
- templates managed by the wxDocManager instance is used to create
- documents and views. Each document template knows what file filters
- and default extension are appropriate for a document/view combination,
- and how to create a document or view.
+When a user interface event occurs, the application @e submits a command to a
+wxCommandProcessor object to execute and store.

 
 

- For example, you might write a small doodling application that can load
- and save lists of line segments. If you had two views of the data -- graphical,
- and a list of the segments -- then you would create one document class DoodleDocument,
- and two view classes (DoodleGraphicView and DoodleListView). You would also
- need two document templates, one for the graphical view and another for the
- list view. You would pass the same document class and default file extension to both
- document templates, but each would be passed a different view class. When
- the user clicks on the Open menu item, the file selector is displayed
- with a list of possible file filters -- one for each wxDocTemplate. Selecting
- the filter selects the wxDocTemplate, and when a file is selected, that template 
- will be used for creating a document and view.
+The wxWidgets document/view framework handles Undo and Redo by use of wxCommand
+and wxCommandProcessor objects. You might find further uses for wxCommand, such
+as implementing a macro facility that stores, loads and replays commands.

 
 

- For the case where an application has one document type and one view type,
- a single document template is constructed, and dialogs will be appropriately
- simplified.
+An application can derive a new class for every command, or, more likely, use
+one class parameterized with an integer or string command identifier.

 
 

- wxDocTemplate is part of the document/view framework supported by wxWidgets,
- and cooperates with the wxView, wxDocument and wxDocManager classes.

 
 

- See the example application in @c samples/docview.

 
 

- To use the wxDocTemplate class, you do not need to derive a new class.
- Just pass relevant information to the constructor including CLASSINFO(YourDocumentClass) 
- and CLASSINFO(YourViewClass) to allow dynamic instance creation.
+@section overview_docview_wxcommandproc wxCommandProcessor Overview

 
 

- If you do not wish to use the wxWidgets method of creating document
- objects dynamically, you must override wxDocTemplate::CreateDocument
- and wxDocTemplate::CreateView to return instances of the appropriate class.
+wxCommandProcessor is a class that maintains a history of wxCommand instances,
+with undo/redo functionality built-in. Derive a new class from this if you want
+different behaviour.

 
 

- @note The document template has nothing to do with the C++ template construct.

 
 
 
 

+@section overview_docview_filehistory wxFileHistory Overview

 
 

- @section overview_docview_wxdocmanager wxDocManager overview
+wxFileHistory encapsulates functionality to record the last few files visited,
+and to allow the user to quickly load these files using the list appended to
+the File menu. Although wxFileHistory is used by wxDocManager, it can be used
+independently. You may wish to derive from it to allow different behaviour,
+such as popping up a scrolling list of files.

 
 

- Class: wxDocManager
+By calling wxFileHistory::UseMenu() you can associate a file menu with the file
+history. The menu will then be used for appending filenames that are added to
+the history.

 
 

- The wxDocManager class is part of the document/view framework supported by wxWidgets,
- and cooperates with the wxView, wxDocument and wxDocTemplate classes.
+Please notice that currently if the history already contained filenames when
+UseMenu() is called (e.g. when initializing a second MDI child frame), the menu
+is not automatically initialized with the existing filenames in the history and
+so you need to call wxFileHistory::AddFilesToMenu() after UseMenu() explicitly
+in order to initialize the menu with the existing list of MRU files (otherwise
+an assertion failure is raised in debug builds).

 
 

- A wxDocManager instance coordinates documents, views and document templates. 
- It keeps a list of document and template instances, and much functionality is routed 
- through this object, such as providing selection and file dialogs. 
- The application can use this class 'as is' or derive a class and override some members 
- to extend or change the functionality.
+The filenames are appended using menu identifiers in the range @c wxID_FILE1 to
+@c wxID_FILE9.

 
 

- Create an instance of this class near the beginning of your application initialization,
- before any documents, views or templates are manipulated.
+In order to respond to a file load command from one of these identifiers, you
+need to handle them using an event handler, for example:

 
 

- There may be multiple wxDocManager instances in an application.
- See the example application in @c samples/docview.
+@code
+BEGIN_EVENT_TABLE(wxDocParentFrame, wxFrame)
+    EVT_MENU(wxID_EXIT, wxDocParentFrame::OnExit)
+    EVT_MENU_RANGE(wxID_FILE1, wxID_FILE9, wxDocParentFrame::OnMRUFile)
+END_EVENT_TABLE()

 
 

+void wxDocParentFrame::OnExit(wxCommandEvent& WXUNUSED(event))
+{
+    Close();
+}

 
 

+void wxDocParentFrame::OnMRUFile(wxCommandEvent& event)
+{
+    wxString f(m_docManager->GetHistoryFile(event.GetId() - wxID_FILE1));
+    if (!f.empty())
+        (void)m_docManager-CreateDocument(f, wxDOC_SILENT);
+}
+@endcode

- Classes: wxCommand, wxCommandProcessor

 
 

- wxCommand is a base class for modelling an application command,
- which is an action usually performed by selecting a menu item, pressing
- a toolbar button or any other means provided by the application to
- change the data or view.
+@section overview_docview_predefid Predefined Command Identifiers
+
+To allow communication between the application's menus and the document/view
+framework, several command identifiers are predefined for you to use in menus.

 
 

- Instead of the application functionality being scattered around
- switch statements and functions in a way that may be hard to
- read and maintain, the functionality for a command is explicitly represented
- as an object which can be manipulated by a framework or application.
-
- When a user interface event occurs, the application @e submits a command
- to a wxCommandProcessor object to execute and store.
-
- The wxWidgets document/view framework handles Undo and Redo by use of
- wxCommand and wxCommandProcessor objects. You might find further uses

-
-
-
- @section overview_docview_wxcommandproc wxCommandProcessor overview
-
- Classes: wxCommandProcessor, wxCommand
-
- wxCommandProcessor is a class that maintains a history of wxCommand
- instances, with undo/redo functionality built-in. Derive a new class from this
- if you want different behaviour.
-
-
-
- @section overview_docview_filehistory wxFileHistory overview
-
- Classes: wxFileHistory, wxDocManager
-
- wxFileHistory encapsulates functionality to record the last few files visited, and
- to allow the user to quickly load these files using the list appended to the File menu.
- Although wxFileHistory is used by wxDocManager, it can be used independently. You may wish
- to derive from it to allow different behaviour, such as popping up a scrolling
- list of files.
-
- By calling wxFileHistory::UseMenu() you can associate a file menu with the file history. 
- The menu will then be used for appending filenames that are added to the history.
-
- Please notice that currently if the history already contained filenames when UseMenu() 
- is called (e.g. when initializing a second MDI child frame), the menu is not automatically
- initialized with the existing filenames in the history and so you need to call
- wxFileHistory::AddFilesToMenu() after UseMenu() explicitly in order to initialize the menu with 
- the existing list of MRU files (otherwise an assertion failure is raised in debug builds).
-
- The filenames are appended using menu identifiers in the range @c wxID_FILE1 to @c wxID_FILE9.
-
- In order to respond to a file load command from one of these identifiers,
- you need to handle them using an event handler, for example:
-
- @code
- BEGIN_EVENT_TABLE(wxDocParentFrame, wxFrame)
-     EVT_MENU(wxID_EXIT, wxDocParentFrame::OnExit)
-     EVT_MENU_RANGE(wxID_FILE1, wxID_FILE9, wxDocParentFrame::OnMRUFile)
