Toolbar for bottom split window - CSplitterWnd

Anu_Bala

I have MDI MFC application. For a particular child window, i want to split in to two. Already i have toolbar for topview by using OnCreate() in ChildFrame.cpp. I want to add toolbar for bottom view also. ChildFrame OnCreateClient() code:

BOOL CChildFrame::OnCreateClient(LPCREATESTRUCT lpcs, CCreateContext* pContext)
{
// TODO: Add your specialized code here and/or call the base class

if(iWindowNumber == 4)
{

CRect cr; 
GetClientRect( &cr);

if (!m\_wndSplitter.CreateStatic(this, 2, 1))
	return FALSE;

if(!m\_wndSplitter.CreateView(0,0, RUNTIME\_CLASS(CTrendView),CSize(cr.Width(), cr.Height()-200),pContext)||		
	!m\_wndSplitter.CreateView(1,0, RUNTIME\_CLASS(CTrendListView),CSize(cr.Width(), cr.Height()-550),pContext))
{
	m\_wndSplitter.DestroyWindow();
	return FALSE;
}
//m\_wndSplitter.SetActivePane(1, 0);
return TRUE;

}
return CMDIChildWnd::OnCreateClient(lpcs, pContext);
}

In OnCreate(), im loading toolbar, but it adds only for TopView. I want to add different toolbar for bootmView. Can we add toolbar using CView::OnCreate()? i tried this but it is not happening. Otherwise i have to create 3 splitter window, middle winodw will have toolbar buttons that can be added using CMiddleView::OnCreate(). How can i get that?

In my CChildFrame::OnCreate(), im loading toolbar but it comes only for top view. But i want for bottom view.

int CChildFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CMDIChildWnd::OnCreate(lpCreateStruct) == -1)
return -1;
// TODO: Add your specialized creation code here

struct tagSIZE butSize,bmpSize;
bmpSize.cx = 25;bmpSize.cy = 23;butSize.cx = 35;butSize.cy = 30;
if(iWindowNumber == 4)
{
	if (!m\_wndWindowTool.Create(this,CBRS\_TOP|CBRS\_TOOLTIPS|CBRS\_FLYBY|WS\_VISIBLE | CBRS\_FLOAT\_MULTI) ||
		!m\_wndWindowTool.LoadBitmap(IDB\_GROUPVW) ||
		!m\_wndWindowTool.SetButtons(CtrlGrp,
		sizeof(CtrlGrp)/sizeof(UINT)))
	{
		TRACE0("Failed to create toolbar\\n");
		return -1;      
	}
	m\_wndWindowTool.SetWindowText("Trend");
	m\_wndWindowTool.SetSizes( butSize,bmpSize );
	m\_wndWindowTool.SetHeight( 40 );

	
	CRect rect;
	m\_wndWindowTool.GetItemRect(0, &rect);
	
	
	m\_wndWindowTool.m\_Static.IsTitle = true;
	if (!m\_wndWindowTool.m\_Static.Create("Title",WS\_CHILD|WS\_VISIBLE|BS\_OWNERDRAW,rect, &m\_wndWindowTool, IDD\_TITLESTATIC) )
	{
		TRACE0("Failed to create combo-box\\n");
		return FALSE;
	}
		}

}

Did you read the article? Did you download the code to test/debug it to know how it works?

I saw that one show CFrameWnd. My window is CMDIChildWnd. So i didnt try first. I tried now. i create CSPlitFrame as CFrameWnd and i coded like below. But when i want my particular window , it shows error on calling that view in Mainframe.cpp.

BEGIN_MESSAGE_MAP(CSplitFrame, CFrameWnd)
ON_WM_CREATE()
END_MESSAGE_MAP()

BOOL CSplitFrame::OnCreateClient(LPCREATESTRUCT /*lpcs*/, CCreateContext* pContext)
{

CTrendListView \*pview;

// Create a context.
CCreateContext context;
pContext = &context;

// Assign custom view.
pContext->m\_pNewViewClass = RUNTIME\_CLASS(CTrendListView);

// Create the view.
pview = (CTrendListView \*) CreateView(pContext, AFX\_IDW\_PANE\_FIRST);
if (pview == NULL)
	return FALSE;

// Notify the view.
//pview->SendMessage(WM\_INITIALUPDATE);
SetActiveView(pview, FALSE);

return TRUE;

}

int CSplitFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;

// TODO:  Add your specialized creation code here


if (!m\_wndWindowTool.CreateEx(this, TBSTYLE\_FLAT, WS\_CHILD | WS\_VISIBLE | CBRS\_TOP
	| CBRS\_GRIPPER | CBRS\_TOOLTIPS | CBRS\_FLYBY | CBRS\_SIZE\_DYNAMIC) ||
	!m\_wndWindowTool.LoadToolBar(IDR\_MAINFRAME))
{
	TRACE0("Failed to create toolbar\\n");
	return -1;      // fail to create
}

m\_wndWindowTool.EnableDocking(CBRS\_ALIGN\_ANY);

m_wndWindowTool.SetBorders(3, 3, 3, 3);
EnableDocking(CBRS_ALIGN_ANY);
DockControlBar(&m_wndWindowTool);
return 0;

}

CChildFrame.cpp OnCreateClient()

if (!m_wndSplitter.CreateStatic(this, 2, 1))
return FALSE;

if(!m\_wndSplitter.CreateView(0,0, RUNTIME\_CLASS(CTrendView),CSize(cr.Width(), cr.Height()-200),pContext)||		
	!m\_wndSplitter.CreateView(1,0, RUNTIME\_CLASS(CSplitFrame),CSize(cr.Width(), cr.Height()-550),pContext))
{
	m\_wndSplitter.DestroyWindow();
	return FALSE;
}

But it shows error in calling TrendView()

if( pTrendDisplayFrame == NULL )
{
iWindowNumber = 4;
CDocTemplate *pTemplate = theApp.pTrendViewTemplate;
CCS3OprDoc* pDoc = new CCS3OprDoc;
pTrendDisplayFrame = (CMDIChildWnd *)pTemplate->CreateNewFrame( pDoc ,NULL ); //It shows error in creating new MDIChhildWnd
if( pTrendDisplayFrame == NULL )
{
MessageBox( "Unable to Create Trend Display" );
return;
}
pTemplate->InitialUpdateFrame( pTrendDisplayFrame,NULL );
}
else
MDIActivate( pTrendDisplayFrame );

When i create SplitFrame as MDICHildWnd, it shows asse

Where exactly the Assertion fails?

If i use

class CSplitFrame : public CframeWnd

Here, I call the TrendView using following fucntion in mainfrm.cpp,

void CMainFrame::OnTrendview()
{

if( pTrendDisplayFrame == NULL )
{
	iWindowNumber = 4;
	CDocTemplate \*pTemplate = theApp.pTrendViewTemplate;
	CCS3OprDoc\* pDoc = new CCS3OprDoc;
	pTrendDisplayFrame = (CMDIChildWnd \*)pTemplate->CreateNewFrame( pDoc ,NULL );
	if( pTrendDisplayFrame == NULL )
	{
		MessageBox( "Unable to Create Trend Display" );
		return;
	}
	pTemplate->InitialUpdateFrame( pTrendDisplayFrame,NULL );
}
else
	MDIActivate( pTrendDisplayFrame );

}

Here it comes messagebox “Unable to create trend display” becoz pTrendDisplayFrmae is null. Frame is not created in CreateNewFrame(),it return null from this function call from doctempl.cpp

// create new from resource
if (!pFrame->LoadFrame(m_nIDResource,
WS_OVERLAPPEDWINDOW | FWS_ADDTOTITLE, // default frame styles
NULL, &context))
{
TRACE(traceAppMsg, 0, "Warning: CDocTemplate couldn't create a frame.\n");
// frame will be deleted in PostNcDestroy cleanup
return NULL;
}

When I use CsplitFrame as MDIChilWNd

class CSplitFrame : public CMDIChildWnd

IT shows assertion error in winmdi.cpp

// walk up two parents for MDIFrame that owns MDIChild (skip MDIClient)
CMDIFrameWnd* CMDIChildWnd::GetMDIFrame()
{
ASSERT_KINDOF(CMDIChildWnd, this);
ASSERT(m_hWnd != NULL);
HWND hWndMDIClient = ::GetParent(m_hWnd);
ASSERT(hWndMDIClient != NULL);

CMDIFrameWnd\* pMDIFrame;
pMDIFrame = (CMDIFrameWnd\*)CWnd::FromHandle(::GetParent(hWndMDIClient));
ASSERT(pMDIFrame != NULL);
ASSERT\_KINDOF(CMDIFrameWnd, pMDIFrame); //Assertion error occurred here
ASSERT(pMDIFrame->m\_hWndMDIClient == hWndMDIClient);
ASSERT\_VALID(pMDIFrame);
return pMDIFrame;

}

My TrendView base class is

class CTrendView : public CView

TrendListView base class is also CView

class CTrendListView : public CView

Im invoking this TrendListView as follow

void CMainFrame::OnTrendListView()
{
// TODO: Add your command handler code here
iGraphView = 0; //Code added by Mohan //Graph view inactive
if( pTrendListDisplayFrame == NULL )
{
iWindowNumber = 11;
CDocTemplate *pTemplate = theApp.pTrendListViewTemplate;
CCS3OprDoc* pDoc = new CCS3OprDoc;
pTrendListDisplayFrame = (CMDIChildWnd *)pTemplate->CreateNew

return;

pTemplate->InitialUpdateFrame( pTrendListDisplayFrame ,NULL );

else
MDIActivate( pTrendListDisplayFrame );

}

What is the theApp.pTrendListViewTemplate? How is it defined/initialized?
