Fields to store cached instances of reader and writer drivers for each format are added in CDF_Application. Method DefineFormat() is added in TDocStd_Application, allowing defining format completely by single call, including drivers to be used for persistence. All OCAF driver packages provide static method DefineFormat() that defines standard OCAF persistence format supported by corresponding package; these methods are called in DRAW to enable all persistence by default. DRAW commands (except TObj-specific ones) now use single instance of OCAF Application, returned by DDocStd::GetApplication(). Other instances are eliminated, as well as method DDocStd::Find(const Handle(TDocStd_Application)&). Method MessageDriver() and relevant field are moved to TDocStd_Application from its descendants. Method CDF_Application::ReaderFromFormat() is made virtual to allow its redefinition in descendants. Creation of storage driver is moved from PCDM::StorageDriver() to new virtual method CDF_Application::WriterFromFormat(). The code loading driver as plugin is retained in both these methods for compatibility. Test command OCC24925 is converted to use virtual methods instead of defining plugin resource. Migration table for old OCAF types is hard-coded in Storage_Schema::CheckTypeMigration(). Removed obsolete and unused items: - FWOSPlugin library (driver is created directly) - Methods in classes CDM_Document dealing with unused parameters of format - DRAW command OCC23010 for testing non-reproducible issue #23010 - Methods PCDM::StorageDriver(), PCDM::FindStorageDriver() - Method Formats() from CDF_Application and descendants - Methods LoadExtensions and SchemaName from PCDM_StorageDriver - Method Plugin::AdditionalPluginMap() - Method BinLDrivers_DocumentStorageDriver::SchemaName() - Method CDF_Application::DefaultExtension(), Reader(), FindReader(), FindReaderFromFormat() - Method CDF_Store::Check()

Sample Open Cascade Demo Presentation Application
========================================================================
This application is a one from a set of applications intended to show
some features of Open Cascade.
You can see how a particular feature is realized in the source code.
The WNT implementation uses Microsoft Foundation Classes.
/////////////////////////////////////////////////////////////////////////////
Summary of what you will find in each of the files that
make up this application.
Below the string <Project> should be substituted by the name of the
particular project downloaded by you.
<Project>/
This folder contains source files specific to this project.
<Project>.dsp
This file (the project file) contains information at the project level
and is used to build a project.
<Project>/<Project>_Presentation.h, <Project>/<Project>_Presentation.cpp
These files contain the project presentation class <Project>_Presentation,
which inherits OCCDemo_Presentation and determines the samples and
the behaviour of all samples in the presentation.
<Project>_Presentation.cpp contains also the initialisation of the
pointer OCCDemo_Presentation::Current with the new object of type
<Project>_Presentation.
Common/
This folder contains source files common to all possibly downloaded
projects.
Common/OCCDemo_Presentation.h, Common/OCCDemo_Presentation.cpp
These files contain the abstract class OCCDemo_Presentation which is
the base for all project presentation classes. It serves as a link
between a platform independent project class and the platform dependent
classes responsible for drawing objects on the screen (mainly
COCCDemoDoc class). OCCDemo_Presentation class contains static field
Current which points to a particular object of type <Project>_Presentation.
This pointer is initialized where <Project>_Presentation is implemented,
and is used by the class COCCDemoDoc.
Common/WNT/OCCDemo.h, Common/WNT/OCCDemo.cpp
These files contain the main application class COCCDemoApp.
Common/WNT/MainFrm.h, Common/WNT/MainFrm.cpp
These files contain the frame class CMainFrame, which is derived from
CFrameWnd and controls all SDI frame features.
Common/WNT/OCCDemoDoc.h, Common/WNT/OCCDemoDoc.cpp
These files contain COCCDemoDoc class which inherits CDocument. It
controls the sequence of samples using the pointer
OCCDemo_Presentation::Current. It also contains the objects of types
AIS_InteractiveContext and V3d_Viewer to store and manipulate the
drawable objects. It also manipulates by the object of type CResultDialog
in which the source code and results of samples are shown.
Common/WNT/OCCDemoView.h, Common/WNT/OCCDemoView.cpp
These files contain COCCDemoView class which inherits CView. It processes
all mouse and keyboard events dedicated to the 3d View.
Common/WNT/ResultDialog.h, Common/WNT/ResultDialog.cpp
These files contain the class CResultDialog which is used to show
the source code and results of samples.
Common/WNT/StdAfx.h, Common/WNT/StdAfx.cpp
These files are used to build a precompiled header (PCH) file
named <Project>.pch and a precompiled types file named StdAfx.obj.
Common/WNT/Resource.h
This is the standard header file, which defines new resource IDs.
Microsoft Visual C++ reads and updates this file.
Common/WNT/OCCDemo.rc
This is a listing of all of the Microsoft Windows resources that the
program uses. It includes the icons and bitmaps that are stored
in the RES subdirectory.
Common/WNT/res/OCCDemo.ico
This is an icon file, which is used as the application's icon. This
icon is included by the main resource file OCCDemo.rc.
Common/WNT/res/OCCDemo.rc2
This file might contain resources that are not edited by Microsoft
Visual C++. Really it is empty.
Common/WNT/res/Toolbar.bmp, Common/WNT/res/Toolbar1.bmp
These files contain bitmaps used to create tiled images for the toolbars.
Common/ISession/ISession_Curve.h, Common/ISession/ISession_Curve.cpp
These files define the class ISession_Curve which is derived from
AIS_InteractiveObject. It is intended to display Curves directly
(not via Edges) in the AIS_Interactive_Context.
Common/ISession/ISession_Surface.h, Common/ISession/ISession_Surface.cpp
These files define the class ISession_Surface which is derived from
AIS_InteractiveObject. It is intended to display Surfaces directly
(not via Faces) in the AIS_Interactive_Context.
