Associating splitter views to document?

Hi there
I have posted this question before, though formulated differently, and
probably not understandable - so I'll try again!
Here's my problem. I have a mainframe with a static splitter window. The two
panes in the splitter have two different views both derived from CView. My
problem is how I can associate the two Views with the mainframe document. In
the document template definition I can only add one view to the document.
How can I 'tell' the second view that its associated with this document?
Hope this question makes any sense :0)

Have you tried CDocument::AddView(CView* pView)? This member function attaches
the view to the document and sets the view's document pointer to the document.
Hope this helps,

You can only associate one view class to a document through doc template.
But you can create your own CCreateContext before creating view so that
you can attach what ever view you like to the document.

My first hint for the future is to scan the MFC samples. Most problems I
have I can find a solution for among the samples. This one I found in the
viewex sample.
Here the solution that I have been using for my MDI apps.
Derive a class from CMDIChildWnd, add a variable of type CSplitterWnd and
override the OnCreateClient() function.
In your AddDocTemplate put the CDerivedChildWnd as view class
Good Luck!
Mats
Here are some code for the above as well:
BOOL CMyApp::InitInstance()
{
...
AddDocTemplate(new CMultiDocTemplate(IDR_MASKEDTYPE,
RUNTIME_CLASS(CWinMaskDoc),
RUNTIME_CLASS(CSplitterMDIFrame), // splitter MDI child
frame
RUNTIME_CLASS(CWinMaskView)));
...
}
class CSplitterMDIFrame : public CMdiChildWnd
{
DECLARE_DYNCREATE(CSplitterMDIFrame)
protected:
CSplitterMDIFrame (); // protected constructor used by dynamic
creation
// Attributes
protected:
CSplitterWnd m_wndSplitter;
public:
// Operations
public:
// Implementation
public:
virtual ~CSplitterMDIFrame();
virtual BOOL OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext
);
// Generated message map functions
//{{AFX_MSG(CMaskFrame)
//}}AFX_MSG
DECLARE_MESSAGE_MAP()
#ifdef _DEBUG
virtual void AssertValid() const;
virtual void Dump(CDumpContext& dc) const;
#endif
};
// Here is the code for the OnCreateClient()
BOOL CSplitterMDIFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{
// first create the static splitter window with two panes
if(!m_wndSplitter.CreateStatic(this, 1, 2, WS_CHILD | WS_VISIBLE |
WS_VSCROLL| WS_HSCROLL))
{
TRACE("Failed to CreateStatic Splitter\n");
return FALSE;
}
// create the views that are to be connected to the splitter panes
// pContext contains the document to be used and in the third parameter
you
// decide which view class to use for this pane (in this case CFirstView)
if (!m_wndSplitter.CSplitterWnd::CreateView(0, 0,
RUNTIME_CLASS(CFirstView), CSize(60, 30), pContext))
{
TRACE("Failed to create pane 0,0\n");
return FALSE;
}
// the second pane
if (!m_wndSplitter.CSplitterWnd::CreateView(0, 1,
RUNTIME_CLASS(CSecondView), CSize(35, 30), pContext))
{
TRACE("Failed to create pane 0,1\n");
return FALSE;
}
return TRUE;
}

Here is what I have done if you're interested. I have two views as
well, but only register the one:
In my windupe.cpp (derived from CWinApp):
CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate(
IDR_WINDUPTYPE,
RUNTIME_CLASS(CWindupeDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CWindupeTreeView));
AddDocTemplate(pDocTemplate);
// create main MDI Frame window
CMainFrame* pMainFrame = new CMainFrame;
if (!pMainFrame->LoadFrame(IDR_MAINFRAME))
return FALSE;
m_pMainWnd = pMainFrame;
Then, I create the splitter and then add the two views it. This is in
the CChildFrame, but you can just as easily put it into your mainframe
class:
BOOL CChildFrame::OnCreateClient( LPCREATESTRUCT /*lpcs*/,
CCreateContext* pContext)
{
CWindupeApp* pApp = (CWindupeApp*)AfxGetApp();
CRect rect;
CSize size;
BOOL bSuccess;
GetClientRect( &rect );
bSuccess = m_wndSplitter.CreateStatic( this, 1, 2,
WS_CHILD | WS_VISIBLE, AFX_IDW_PANE_FIRST );
// calculate the size of the tree view and create
size = rect.Size();
UINT TreeViewPos = pApp->GetProfileInt( _T("General"),
_T("TreeViewPos"), 333 );
size.cx = ( int )(( TreeViewPos*size.cx) / 1000 );
bSuccess &= m_wndSplitter.CreateView( 0, 0, RUNTIME_CLASS(
CWindupeTreeView ), size, pContext );
// calculate the size of the list view and create
size = rect.Size();
UINT ListViewPos = pApp->GetProfileInt( _T("General"),
_T("ListViewPos"), 667 );
size.cx = ( int )(( ListViewPos*size.cx) / 1000 );
bSuccess &= m_wndSplitter.CreateView( 0, 1, RUNTIME_CLASS(
CWindupeListView ), size, pContext );
return bSuccess;
}
That's all there is to it. You obviously do not need to use the code that calls
the GetProfileInt. I store the percentage position of the views based on the
overall child window size and restore it when the child window is restore.

Have you tried CDocument::AddView(CView* pView)? This member function attaches
the view to the document and sets the view's document pointer to the document.

Hi, You have to have a derived frame from CFrameWnd and use the
OnCreateClient to create the splitter - should be a member in the frame -
and all views.
The view assosieted with the frame and document in the template can you find
in the CCreateContext but you can use any view in the application for the
panes. bu using the RUNTIME_CLASS macro or get a CRuntimeClass from the
document (for dynamic view selection).
I think there is a sample how to use the splitter with different views but
here is how I use the function:
BOOL ActProgramFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext*
pContext)
{
// if a normal view is created the splitter should have AFX_IDW_PANE_SAVE as ID
// create the splitter window (2 rows, 1 col) and fill in the frames (views)
if ( ! m_wndSplitter.CreateStatic(this, 2, 1 ) )
{
TRACE0("Unable to create the splitter in ActProgramFrame\n");
return FALSE;
}
// create first pane, allways a ActProgramView
if ( ! m_wndSplitter.CreateView(0, 0, RUNTIME_CLASS(ActProgramView),
CSize(250, 250), pContext) )
{
TRACE0("Unable to create a ActProgramView pane\n");
return FALSE;
}
// create second pane, allways a ActSymbolView
if ( ! m_wndSplitter.CreateView(1, 0, RUNTIME_CLASS(ActSymbolView),
CSize(150, 150), pContext) )
{
TRACE0("Unable to create a ActSymbolView pane\n");
return FALSE;
}
return TRUE;
}
Hope this help.
