CSingleDocTemplate::CSingleDocTemplate
构造 CSingleDocTemplate 对象。
CSingleDocTemplate(
UINT nIDResource,
CRuntimeClass* pDocClass,
CRuntimeClass* pFrameClass,
CRuntimeClass* pViewClass
);
参数
nIDResource
指定资源的ID用于文件类型。这可能包括菜单、图标、快捷键对应表和字符串资源。字符串资源包括“\ n字符分隔的七子字符串(“\ n符必须作为占位符,如果子字符串不包括在内;但是,后缀“\ n字符不是必需的);这些子字符串描述文件类型。有关子字符串的信息,请参见 CDocTemplate::GetDocString。该字符串资源在应用程序的资源文件中找到。例如:
// MYCALC.RC
STRINGTABLE PRELOAD DISCARDABLE
BEGIN
IDR_MAINFRAME "MyCalc Windows Application\nSheet\nWorksheet\n Worksheets (*.myc)\n.myc\nMyCalcSheet\n MyCalc Worksheet"
END
使用字符串编辑器,可以编辑此字符串;整个字符串形式出现在字符串编辑器的条目,不为七不同项。
有关这些资源类型的更多信息,请参见 字符串编辑器。
pDocClass
指向 CRuntimeClass 文档选件类的对象。此选件类是 CDocument-您定义了表示您的派生类文档。pFrameClass
指向 CRuntimeClass 框架窗口选件类的对象。此选件类可以是 CFrameWnd派生类也可以是 CFrameWnd,如果您希望自己的主框架窗口的默认行为。pViewClass
指向 CRuntimeClass 视图选件类的对象。此选件类是 CView-您定义显示您的派生类文档。
备注
请动态分配一 CSingleDocTemplate 对象并将其传递给从应用程序选件类的 InitInstance 成员函数的 CWinApp::AddDocTemplate。
示例
// The following code fragment is from CMyWinApp::InitInstance.
// CMyWinApp is derived from CWinApp.
// Establish the document type
// supported by the application
AddDocTemplate(new CSingleDocTemplate(IDR_MAINFRAME,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CMyView)));
// The following code fragment is from CMyWinApp::InitInstance.
// CMyWinApp is derived from CWinApp.
// Normally, an application creates a document
// template and registers it with MFC as a part
// of its initialization.
// IDR_SAMPLERESOURCE is a resource ID string;
// see the CDocTemplate class overview documentation
// for more information on its format.
// The next three parameters use the RUNTIME_CLASS()
// macro to get runtime type information for the doc,
// frame, and view classes that will be associated by
// the template.
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(IDR_MAINFRAME,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CMainFrame), // main SDI frame window
RUNTIME_CLASS(CMyView));
if (!pDocTemplate)
return FALSE;
// After the following call, MFC is aware of the doc
// template and will free it when the application is
// shut down. The doc templates known to MFC will
// automatically be used when CWinApp:OnFileOpen() or
// CWinApp::OnFileNew() are called.
AddDocTemplate(pDocTemplate);
