Hi,
I'm writing an 3D editor and I'm trying to get my viewport arrangement running.

I thought I should create it like this:

CMainWnd (CWnd)
-- CViewport x 4 (CView)
---- CViewportControl (CFormView)
---- CCameraView (CView. My CD3D9View actually..)

I then place four CViewport in a splitter window. The problem is that i don't know how to place the CViewportControl FormView inside the CViewport view. For some reason I had no problems with creating the CCameraView but the CFormView is a b**ch... I successfully added it with an odd hack but whenever I clicked it the came crashed with an odd assertion. How do I create it when there is no "Create()"?

u really need a view inside a view. if so it has to be in a splitter again. thats teh right approch. or else go for a dockable style dialog inside a view.

what do u think?

The thing is that I'm a total newbie with MFC so I don't really know how to do it. The CViewport "view" doesn't have to be a view I suppose, only the CCameraView has to be a view since it's the only part of the "framework" that actually display data from the document. What class should i derive CViewport from instead and how do I add controls (a combo and a checkbox) to a dockable toolbar?

Could anyone guide me how I should structure the classes to make a viewport window like the ones you see in 3dsmax, maya etc.

I hope my questions doesn't sound too confusing, though I AM really confused about MFC. Whatever I do seems to cause assertions and trace errors or odd memory exceptions Frown | :(

I just realized after typing my response that the creation of the sub-view wasn't the problem. The problem was with creating the "control panel" inside each viewport from my dialog resource. How the heck do I do that? Big Grin | :-D

So do you have this part working?

Yeah. But each frame in the splitter (2x2) is a CViewport which I derive from CView. Shoulw it really be derived from a CView when it's not hosting and "viewing code" in itself, but only exists as a host frame of a control bar for the viewport and the real view (CCameraView)?

I know I'm making this hard to understand Frown | :(

What I want is the exact same feature as in 3dsmax. 4 viewports in a splitter. Each viewport should contain a combobox where you can select what view/camera that will be used. There will also be a button there to toggle maximization of the viewport. Below this "control bar" the actual view will placed.

I started with MFC just a couple of days ago so I really don't know how to construct this kind of layout.

Re: Add multiple CView/CFormView to a CView? [modified]

4-Aug-06 6:04

I've only used a splitter window a few times and they were both 1Rx2C. Both panes had a CView-derived object in it (one was a CListView and the other was a CTreeView). I've seen examples of more, however. In those, the main splitter window had two panes, both of which were CSplitterWnd objects. Now you have two splitter windows (inside the one main splitter window), with two panes each. In those four panes can be whatever CView-derived objects you need. Make sense?

But can I create something else than a CView derived object in a splitter window pane?

What class is used for generic window/panels? Is it CWnd?

Can I add a CWnd to a splitetr pane and then add an additional CWnd inside that CWnd? I'm at work atm so I can't test for myself :P

Maybe, but having never done otherwise, I can't say for sure.

A CView-derived object, I presume.

That's what I eluded to in my last response. The main splitter window had two panes, each of which was a CSplitterWnd object. Both of those splitter windows had two panes, and the resulting four panes held other (CView) objects.

ANSI C Standard Library in VC8 [modified]

Is there a way of using the ANSI C Library in VC8?

Basically can I use fopen and so on?
In a normal Win32 project it says the methods are deprecated (yes I know I can use fopen_s but for project reasons I have to use fopen (and would rather not write a whole bunch of macros).

deprecated doesn't mean unusable...

it is only an advice not to do so, but yes, you still can use them.

Hmm... I seem to remember (from yesterday) that when I tried to open a stream using fopen it returned a null, even though the file was valid (tried the same code on my home workstation using gcc and it worked fine).

I will investigate anyway, thanks a lot.
