SDI and Tab Manager

Oleg,

In the TabManager sample is something called CXTPTabClientWnd.  Is there a way to use this in an SDI application (have each view (tab client) point to the same document)?

Im probably way off, but what if CMyAppView (the generated view class) acted as a placeholder who's only job in life is to provide its window to one of its member variables that is a CXTPTabClientWnd.  Then when I want to create a new view as a tab client,  I ask my host view's CXTPTabClientWnd to do so.

I wanted to ask first because the docs for TabClientWnd are sparse and mention MDI a lot.

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

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.

Use the WS_CLIPCHILDREN window style for your tab control.

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.
