Well Chuck I am afraid you have to do it all yourself since Windows does =
=3D
not handle the WS_CAPTION style for child windows and the views are =3D
child windows of the SplitterWnd. I read an article about it in the =3D
Windows Development Journal which dealt with the topic and actually used =
=3D
some code of it. However I had to modify some stuff to get the right =3D
behaviour. I give the implementation of my view class in the following =3D
it is part of a shipping application and has not caused any problems. I =3D
always use this view and when I don't need the captions I just set it to =
=3D
zero. BTW you MFC-Developers here on the list: wouldn't it be a good =3D
idea to add that pseudo-caption to CView. It is always a little bit =3D
confusing when using splitters to determine which view actually has =3D
focus, so many people will end up writing code like this.
But here is the code:
All Stuff overridden with Class Wizard exept the following 4 methods:
.H-File
void SetCaptionHeight(UINT nHeight) {m_nCaptionHeight =3D3D nHeight;}
UINT nCaptionHeight() const {return m_nCaptionHeight;}

CString strCaption() const {return m_strCaption;}
.CPP-File

To make your title bar showing, try this :
void CTitleView::OnInitialUpdate()=20
{
CFormView::OnInitialUpdate();

DWORD dwStyle =3D ::GetWindowLong(m_hWnd, GWL_STYLE);

I believe Chuck is asking a question that cannot be found in the VC++
help. When you create a splitter with two views in Win32, the only title
bar that appears is the one on the frame window. Even if you set the
titlebar style for the view window, a title bar does not appear. In VC++
1.5 (16 bit) the second title bar appeared. Chuck's question is a valid
one and I wait to see the response.

Kevin,
that would be an easy way - however your suggested solution has at least two undesired side-effects:
1. You cannot activate your view by clicking on the caption - at least the caption is not shown in highlighted state.
2. You can actually *move* the view to a different location by dragging the caption!
Sorry to say but the only working way of having a caption on a view is to draw it yourself.
Best regards,
Lin

Subject: How to let views in a splitter window have their own title
Author: mfc-l@netcom.com at vhsunix
Date: 12/7/96 9:30 PM
Environment: MSVC++ 4.0, Win NT 3.51
Problem statement:
A splitter window holds two form views created from dialog box templates.
I'd like to let each view have its own title bar to indicate which view is
the active view and display some info on the title bar. However,
even if I check the "Title Bar" box for the dialog box template style,
the title bar still does not show up. How to make this work?
Please give me some hints on this. Thanks in advance.
