Question about DockPane, CView & Document

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I'd like to create two DocPanes at the begin of program starting up, and I intend to add the imbeded views to the doc's view list,  thus I can manage all views more easily, but error was occured for the doc obj. itself was not initialized.
who know how the MFC framework could concord the doctemplate, doc, MainFrame, and views, why I cannot associate my newly created views with the Doc?  
I tried to use CCreateContext, but at the time, I can use this->GetActiveDocument(), or use this->GetActiveView()->GetDocument() in MainFrame to obtain the right Doc ptr.
I'm Waiting for the correct methods.
Best Regards

	Hi, Does anyone has ideas, don't hesitate, just reply it. I'm wondering how the virtual function of OnCreateClient can pass the CCreateContext object correctly. How to construct it, wow, I'm bothering with it.

	Hi, Ok, just a simple example: in your Applic.h: *CMultiDocTemplate m_pTemplate;** in your Applic.cpp: m_pTemplate = new CMultiDocTemplate(IDR_MAINFRAME, RUNTIME_CLASS(CYourDocument), RUNTIME_CLASS(CYourFrame), RUNTIME_CLASS(CYourView)); AddDocTemplate(m_pTemplate); What happened? you have created a document template, which will help you to create some views (CYourView) inside some frame windows (CYourframe) which are linked to a document (CYourDocument) Now we will create programatically a new view attached to the document. We have saved the templates's pointer to use it anywhere in the application class. First, we create a document: CDocument* pDocument = m_pTemplate->CreateNewDocument(); ASSERT_VALID(pDocument); then, we create the frame and give it the document because the frame will create the view in the method OnCreateClient(...): *CFrameWnd pFrameWnd = m_pTemplate->CreateNewFrame( pDocument, NULL ); ASSERT_VALID(pFrameWnd); And a least, we call the InitialUpdate frame. m_pTemplate->InitialUpdateFrame( pFrameWnd, pDocument );** You have now a new MDI window. If you want to create a view inside a docking pane, that is very easy and you will find in this site a lot of example. A simple example now (from the MainFrm.cpp): CXTPDockingPane* pwndPane = m_paneManager.CreatePane( IDR_PANE_SETTINGS, // Pane ID rcLeftPane, // Bounding rectangle xtpPaneDockLeft); ASSERT(pwndPane); pwndPane ->AttachView( this, RUNTIME_CLASS(CYourView), m_pDocument, NULL); //m_pDocument can be created from a template class Now you have a docking pane with a view attached to a document. If you need to use your own frame (and not a CFrameWnd), have a look at the method "AttachView". I Hope I helped you regards

	Thank you, though I've implemented this days before. I don't know if your method could attach newly created view to the viewlist of the document. I use app_ptr to get existed doc_ptr, and existed view_ptr, so I can construct a context, by this way I succeed in completing one doc- severay view structure. Edited by freesong

	This works fine. But if you open and close more than one document thus destroying and creating the pane with a new view/doc attached, the application crashes when you exit. What is the proper function call sequence for "unattaching" the view after call AttachView? I'm getting a crash in the DocumentTemplate class when my app closes.
