How to add tabs to CView Class?
-
First of all, create an CTabbedView derived from CTabView.
class CTabbedView : public CTabView
{
protected: // create from serialization only
CTabbedView();
DECLARE_DYNCREATE(CTabbedView)
...
};Then, in OnCreate:
int CTabbedView::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CTabView::OnCreate(lpCreateStruct) == -1)
return -1;m\_wndTabs.DestroyWindow(); if (! m\_wndTabs.Create(CMFCTabCtrl::STYLE\_3D, CRect(0, 0, 0, 0), this, 1, CMFCTabCtrl::LOCATION\_BOTTOM)) { TRACE(\_T("Failed to create output tab window\\n")); return -1; } m\_wndTabs.SetFlatFrame(); m\_wndTabs.SetTabBorderSize(0); m\_wndTabs.AutoDestroyWindow(TRUE); AddView(RUNTIME\_CLASS(CYourView1), \_T("Title 1")); AddView(RUNTIME\_CLASS(CYourView2), \_T("Title 2")); return 0;}
and in your childframe, where you create the view inside your splitter, you can put this CTabbedView as any CView:
if(! m\_wndSplitterTab.CreateView(1, 0, RUNTIME\_CLASS(CTabbedView), CSize(0, 0), pContext)) { m\_wndSplitterTab.DestroyWindow(); return FALSE; }Tell me if is not clear.
Thank you very much. It does not work even i followed the same code which you posted now and earlier. You can find the attached image which shows how i created the 5 views in my application using csplitterwnd class. In view 5 i need to add some tabs. I written a class CMyTabClass which derives from CTabView. i given this class as a RUNTIME_CLASS to view 5 as follows: bStatus = SpliterObj()->CreateView ( 1, 1, RUNTIME_CLASS(CMyTabClass), sizeView, pContext ); In CMyTabClass i created the tab as follows: if (!tab.Create(CMFCTabCtrl::STYLE_FLAT, CRect(150, 524, 250, 366), GetSplitter0()->GetPane(0, 0), 1)) { TRACE0("Failed to create output tab window\n"); return -1; // fail to create } Some times i feel the coordinates may be wrong(150,524,250,366) and hence the tab is located out side the view. I changed many times but still the tab is not visible in view 5. Click below for image Link: [^]

Could you reproduce more accurate my example in your code ? For instance, in my example CRect has 0 value ... and there is more.
I created a sample MFC application with single document template and added the Class which derived from CTabView and created another class which derives from CView. class MyTabClass : public CTabView { //this class created a window with tab control below. But not tab exactly. //Now i added below piece of code to create a tab. int OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CTabView::OnCreate(lpCreateStruct) == -1) return -1; // TODO: Add your specialized creation code here AddView(RUNTIME_CLASS(CView1), _T("View1")); return 0; } } The above code created a single tab on window as shown in below image. [^] But all i need to know is how to create this same tab on Splitter Window which is shown in my first image. A great thanks for you in quick response and support. Please let me know what wrong i did in adding the tab on csplitter window.

My sample code was for splitter case ... do you want to add tab views inside an frame, or inside an splitter ?
My childframe class contains 5 splitter windows. In one of splitter window i need to create tab. My app code as follows: BOOL CChildFrame::OnCreateClient ( LPCREATESTRUCT lpcs, CCreateContext* pContext ) { UNREFERENCED_PARAMETER (lpcs); CString csMessage = _T(""); CMainFrame* pMainFrame = (CMainFrame*) theApp.m_pMainWnd; // In floating views mode, do setup specific to it: // Create the appropriate view for it. switch (m_iCreationIndex) { case VIEW1: { // Create a four pane splitter window to use solely to pre-create the needed views. BOOL bStatus = GetSplitterObj()->CreateStatic ( this, 2, // rows 3 // columns ); if (FALSE == bStatus) { TRACE0 ("Failed to create splitter window.\n"); return FALSE; } // Create the five views when the first child frame is created. CSize sizeView (0,0); bStatus = GetSplitterObj()->CreateView ( 0, 0, RUNTIME_CLASS (MyScrollClass), sizeView, pContext ); //like wise view 2, view 3 , view 4 and below is view 5 bStatus = GetSplitterObj()->CreateView ( 1, 1, RUNTIME_CLASS (MyTabClass), sizeView, pContext ); } } } // Disconnect views from splitter window. // They will be attached to the appropriate // floating child frame as they are created. pView1->SetDlgCtrlID (-1); pView1->SetParent (this); pView1->ShowWindow (SW_HIDE); pView2->SetDlgCtrlID (-1); pView2->SetParent (this); pView2->ShowWindow (SW_HIDE); pView3->SetDlgCtrlID (-1); pView3->SetParent (this); pView3->ShowWindow (SW_HIDE); pView4->SetDlgCtrlID (-1); pView4->SetParent (this); pView4->ShowWindow (SW_HIDE); pView5->SetDlgCtrlID(-1); pView5->SetParent(this); pView5->ShowWindow(SW_HIDE); // Distroy the obsolete splitter window. GetSplitterObj()->SetDlgCtrlID (-1); GetSplitterObj()->SetParent (NULL); GetSplitterObj()->ShowWindow (SW_HIDE); GetSplitterObj()->DestroyWindow(); delete GetSplitterObj(); GetSplitterObj(NULL); The above piece of code created 5 splitter windows successfully. In Pane(1,1) i need to add tabs. MyTabClass is derived from CTabView. In MyTabClass, i created tab control as follows as you explained above. int MyTabClass::OnCreate(LPCREATESTRUCT lpCreateStruct) { if (CTabView::OnCreate(lpCreateStruct) == -1) return -1; if (!m_tab.Create(CMFCTabCtrl::STYLE_3D, CRect(0, 0, 0,

On splitter window tab control not added. tab.Create() function returns true but tab control is not visible on splitter window.

Dear member, in order to read easily, please format your code (use "code" button from above edit area). And, yes,
m_tab.Create(...)return TRUE, but further more, you do nothing ...Hey sorry for the wrong indentation. Its working absolutely fine with same piece of code. The problem is what i mentioned earlier i.e., the coordinates what i provided does not show the tab control in my split window. I changed the values with hit and trail and some portion of tab control is visible on split window.
if (!m_tab.Create(CMFCTabCtrl::STYLE_3D, CRect(500, -500, 900, 300), this, 1, CMFCTabCtrl::LOCATION_BOTTOM))
{
TRACE(_T("Failed to create output tab window\n"));
return -1;
}The values 500,-500,900,300 shown the control on my window. I need to write logic to show this control at the bottom of split window. Thanks for your support. Now, i will tweak this and try to add tabs to it. In case of any block i will post it back.

Please correct me if i am wrong. While creating a Split window using below statement.
bStatus = GetSplitterObj()->CreateView ( 1, 1, RUNTIME\_CLASS(CMyTabClass), sizeView, pContext );Above call create Split Window. CMyTabClass is derived from CTabView. So, by default the split window should contain tab splitter at the bottom of the window. Am i right? Because this is how it working in my sample application. In sample i created a Class which derives from CTabView and the window is created with tab splitter in the bottom by default. Later i started adding view using addview(). Then why in my application, splitter is not visible in bottom of the splitter window? why should i explicitly create it using Create()..?

The code:
bStatus = GetSplitterObj()->CreateView
(
1,
1,
RUNTIME_CLASS(CMyTabClass),
sizeView,
pContext
);it is only put CMyTabClass view into your splitter window. The creation of the tabs inside this CMyTabClass should be done in CMyTabClass::OnCreate, where AddView(...) calling is mandatory. So, you should add at least one tab in order to see something inside your splitter window :)

Then how come in sample application, below code itself creating a tab bar (horizontal with arrow buttons) in window?
if (CTabView::OnCreate(lpCreateStruct) == -1)
return -1;The same above piece of code in my application not creating that horizontal tab bar unless i create MFCTabCtl tab; tab.create()....

In above provided sample code, i have some doubts. When i created a class CTabbedView which is inherited from CTabView, in OnCreate(), the below call it self created a tab control (horizontal splitter) without any tabs.
if (CTabView::OnCreate(lpCreateStruct) == -1)
return -1;Then what is the use of below call?
if (!m_tab.Create(CMFCTabCtrl::STYLE_3D, CRect(0, 0, 500, 100), this, 1, CMFCTabCtrl::LOCATION_BOTTOM))
{
TRACE(_T("Failed to create output tab window\n"));
return -1;
}What is the exact difference between AddTab and AddView.?

AddTabcall is creating the tab area: "Call this method to add a pane as a new tab on a tabbed pane" CBaseTabbedPane Class[^] andAddViewcall is creating the view which are hosted by CTabView: "Call this function to add a view to the tab control that is embedded in a frame" CTabView Class[^] -

Lets say. When my application starts user will input a value between 1 to 10. Based on user input i need to create the tabs (no. of tabs). later in each tab in need to display different images. In this case, should i create my class which is inheriting from CTabView or CTabPane?

" should i create my class which is inheriting from CTabView or CTabPane?" Definitely from CTabView. And this CMyTabClass, should include at least one tab, with one view.
If i call AddView(), this itself is creating a tab. Is this not enough? No need to call AddTab() right?

Dear member, in order to read easily, please format your code (use "code" button from above edit area). And, yes,
m_tab.Create(...)return TRUE, but further more, you do nothing ...If i call AddView() and run my program, it working absolutely fine with a window and a view(tab). But instead of calling AddView() initially, at runtime i based on user input, i called addview() which leads to a crash. What could be the reason.
class View : public CScrollView
{}
//below is my main class
class MyTabClass : public CTabView
{
//this function gets called automatically during creation of window.
void OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CTabView::OnCreate(lpCreateStruct) == -1)
return -1;
AddView(RUNTIME_CLASS(View),_T("Sheet1")); //this works fine.
}//this function i will call based on user input and hence its crashing during addView call. void RunTimeBasedOnUserInput() { for(int i = 0 ; i < userinput; i++) { AddView(RUNTIME\_CLASS(View),\_T("sheet %d",i)); } }}
After investigation, what i found is, During creation of window itself, OnInitUpdate function in class View is getting called each time when AddView() is called. But if i create the views dynamically, then AddView() wont call OnInitUpdate of my View class and hence the crash occurs.
