Document Template Creation
| Overview | How Do I | | Tutorial
While creating a new document in response to a New or Open command from the File menu, the document template also creates a new frame window through which to view the document.
The document-template constructor specifies what types of documents, windows, and views the template will be able to create. This is determined by the arguments you pass to the document-template constructor. The following code illustrates creation of a for a sample application:
AddDocTemplate( new CMultiDocTemplate( IDR_SCRIBTYPE,
RUNTIME_CLASS( CScribDoc ),
RUNTIME_CLASS( CMDIChildWnd ),
RUNTIME_CLASS( CScribView ) ) );
The pointer to a new CMultiDocTemplate object is used as an argument to . Arguments to the CMultiDocTemplate constructor include the resource ID associated with the document type's menus and accelerators, and three uses of the macro. RUNTIME_CLASS returns the object for the C++ class named as its argument. The three CRuntimeClass objects passed to the document-template constructor supply the information needed to create new objects of the specified classes during the document creation process. The example shows creation of a document template that creates CScribDoc objects with CScribView objects attached. The views are framed by standard MDI child frame windows.
