Hello,

CXTPTabControl looks great, but I have one question. Does it support multiline tabs or only singleline? I was not able to see it in samples.

Hey here is something that would be great if anyone is up to it:  Using the existing CXTTabControl inside a basic CView (as shown above), anyone think they can bring to life the Tab Group features demonstrated by CXTPTabClientWnd and shown in the TabManager sample application?

The group feature Im refering too is what allows you to create horizontal and vertical tab collections.  To see it in vc++, open a few source files and right-mouse-click on one of their tabs to see "New Tab XXX Group").  To see it in the TabManager sample demo, create a few tabbed docs, then drag a tab to the center of the doc area... you should be presented with the New Tab XXX Group menu.

It looks like there is a lot of maintenance code for this ready to go, its just a matter of taking the TabClientWnd class and replacing it with one that is more SDI-centric. 

Thanks!  This tabcontrol is significantly better than cxttabview.... users can drag-rearrange the tabs.  Hopefully today Ill finish moving over all the features I had in my old cxttabview subclass.

Use the WS_CLIPCHILDREN window style for your tab control.

LOL thanks guys... sometimes you can't see the forest for the trees.  Hey, maybe I WANTED an invisible tab, ever think of that?   Also, my onsize method was calling tabCtrl.OnSize() rather than the much more obvious MoveWindow.  Thanks!

BTW, if you replace CMyApplicationView with a CXTListView for the sake of discussion,  and assume you have a few tabs created, anyone notice the listview flickers like mad whenever the tabs are clicked or the window is resized?   The tabs themselves do not flicker, so I don't think its the creation of the tabCtrl member.

How do you get rid of this flickering? 

Thanks
Doug

Hi Doug,

I tried your code, too. It works after adding the OnSize handling and adding WS_VISIBLE and WS_CHILD flags to the m_tabCtrl.Create. Your code was creating an invisible tab control.

You forget the OnSize message handler. You should have something like this so that m_tabCtrl occupies the complete parent window:

// Resize the list control contained in the view to
// fill the entire view when the view's window is
// resized. CMyView is a CView derived class.
void CMyMainView::OnSize(UINT nType, int cx, int cy)
{
   CView::OnSize(nType, cx, cy);
   // Resize tab control to fill the whole view.
   m_tabCtrl.MoveWindow (0, 0, cx, cy);
}

I hope this solves your problem.

Oh by the way, just remove the WS_CLIPCHILDREN window style for your view. Otherwise the screen will flicker as soon as your view is resized.

How would one then use CXTPTabControl to manage views?  I have a simple generated CView from an SDI app and it has one member variable, m_tabCtrl (an XTPTabControl).

I call m_tabCtrl's Create in the view's OnCreate method.  The OnCreate,  AddATab and CreateView methods shown below try to add one of my app's views to the tabCtrl.

Nothing seems to work right.  Im not sure if I need to do something with my view's OnSize or OnPaint or OnDraw, but I just can't get this to work.  I've tried various onsize, onpaint, ondraw tests but haven't gotten anywhere really. 

Oleg, I know you are a busy guy, but do you have any thoughts on this?

Regards,
Doug
