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.

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 ?

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.

Sure. In my code I give it an empty CRect, and it work fine.

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()....

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
{
}
class MyTabClass : public CTabView
{
void OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CTabView::OnCreate(lpCreateStruct) == -1)
return -1;
AddView(RUNTIME_CLASS(View),_T("Sheet1"));
}
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.
Exception as follows:
---------------------------

Can you let me know how to get rid of this problem?

And what did exactly didn't work when you had applied my example ?
|
|
|
|
|
On splitter window tab control not added. tab.Create() function returns true but tab control is not visible on splitter window.
|
|
|
|

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.?
|

AddTab call is creating the tab area:
"Call this method to add a pane as a new tab on a tabbed pane"
CBaseTabbedPane Class[^]
and AddView call 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[^]
|
|
|
|
|
In my case, i need to create tabs dynamically. 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?
|
|
|
|
|
Yes, AddView() is creating a tab, so, it is enough.

Hi. Have you solved this ?
|
|
|
|
|
I am serializing CMapStringToPtr object without any problem, key by key, pointer to pointer.
For this case, the key order it is matter.
So, if I archive this CMapStringToPtr object, and de-archive on the same machine, the key order are fine. But, if I de-archive this object on other machine, the key order are not the same, and this is a PROBLEM. How can avoid this issue ?
Yes, I could serialize another CStringArray with the CMapStringToPtr keys, but I don't know if this a good idea ... can you tell me how to overcome this problem ?
Thank you.

Key order is not a property of such a collection (see the documentation[^]) unlike, for instance, the std::map.
So yes, you have to work around that.
