Determine size of CFormView panes attached to CSplitterWnd?

I'm not certain I understand exactly. Can't you just call
SetRowInfo/SetColumnInfo and then RecalcLayout?

It's hard to say without seeing what you are describing but isn't the scroll
range determined by the CFormView? You just need to tell the splitter
window.

I am creating an SDI with a splitter and several views based on the
CFormView. I can create and attach them to the CSplitterWnd control fine,
but I want to be able to set the splitters split sizes based on the size
of the form view attached to it.
The form views are defined in a template resource and so have a fixed
size. How to I get this size and then set the splitters pane sizes? The
information must be stored somewhere as when you shrink the splitter via
the divider bar, at some point the pane containing the form view gets a
set of scroll bars added, hence the pane size must be smaller than the
original form views size.
Help much appreciated.
Cheers
David

Hi
Sorry I probably was not clear enough.

I want to be able to call the SetRowInfo/SetColumnInfo members, however
I do not know what size the CFormView is. If I try and call
GetClientRect() it simply returns the size of the splitter pane which
may be bigger or smaller than the CFormView it contains. I just want to
be able to find the size of the CFormView as set in the resource
template and then size my main window and the splitter panes appropriately.

Hope that makes more sense.

Cheers

David.

If you call GetClientRect on the view itself, you should get the right
size. Where are you calling this from?

I have tried this but I only get the size of the view after it is added
to the splitter pane.

The problem seems to be, or at least my problem which could be self
induced, is that I create a static splitter window (CSplitterWnd) and
then add the views. These views are added by a CRuntimeClass pointer,
hence there is no tangible CView at this stage to run the
GetClientRect() on. When you add the view you specify a size parameter
to AddView() which I do not know how to fill in, hence the original
problem.

To get around this I thought I could just come up with a size for the
create view and then adjust it later with the SetRowInfo(), etc calls.
So once I have added the view I can get the CWnd for the view with
GetPane() and this is then my tangible view created for the splitter.
However if I now lookup the size of this view it reports the splitter
pane size I set when I added the view rather than the original size if
the view.

Surely I am doing something obviously wrong here as this cannot be that
difficult! The problem as I see it is that I never create the view
instance in my code and hence cannot do the size lookup there. The view
create is hidden inside the splitter class AddView() call.

Cheers

You can get a pointer to the view using something like:

CMyView *m_pMyView;

m_pMyView = (CMyView*)m_wndMySplitter.GetPane(0,0);

If you know the pane where the view was added.

Yes I can do that but as I said below if you then call GetClientRect()
on the CView/CFormView returned by the GetPane(), the size returned is
the size of the pane specified when you did the AddView() on the
CSplitterWnd, that is the view has taken on the size of the splitter
pane and that is what it is returning to you not the size it was defined
as in its resource template.

Ah, sorry, I missed that part. I remember having this problem in the past
when I wanted my default view for a splitter and formview to not have the
formview scroll. I ended up using the resizable lib code to have it resize
controls, but for the default size I wanted it to fit so I ended up just
changing the values until it ran as expected. Part of the problem is that
the dialog resources is in a different type of unit than the window that is
created so I couldn't figure out a good way to calculate it from the current
size of the resource. I'm sure there is a way, but I only had to do this
once and trial and error was easier.

Tom

Tom
Yes I can do that but as I said below if you then call GetClientRect() on
the CView/CFormView returned by the GetPane(), the size returned is the
size of the pane specified when you did the AddView() on the CSplitterWnd,
that is the view has taken on the size of the splitter pane and that is
what it is returning to you not the size it was defined as in its resource
template.

I cheated. I created a CStatic frame control as large as my dialog, marked it as
invisible, changed its name from IDC_STATIC to IDC_FRAME, and then did a
GetWindowRect/ScreenToClient to find out how wide it was.

Thanks for all the suggestions, sadly most I have tried and do not
work. However by a set of coincidences I have found a partial solution
to this problem which sort of ties up with the behaviour I was seeing.

As I said originally if you resize the window or adjust the splitter
bar, at some point the CFormView added a set of scrollbars when the pane
became smaller than the views resource template defined it to be.
Therefore the CFormView must have this information somewhere inside it.

This is indeed the case and it is stored away in a CSize called
m_totalDev. Unfortunately this is protected, however the total view size
can be retrieved by a call to GetTotalSize() (or GetDeviceScrollSizes()
but this returns a hole load of other stuff as well).

With this I can get the size, which I think are in pixels (MSDN says
they are logical units), of the two CFormViews making up my splitter. I
can then use the SetColumnInfo() member to set the widths of the panes
appropriately.

The problem I still have is that despite all of this, if I try and set
the parent window size with MoveWindow() to the pane width or heights,
there must be a few pixels I am missing in the calculation somewhere as
the panes still get scrollbars added.

I first get the CFormView size with GetTotalSize(). Then I get the main
frames client size with GetClientRect(). I then get the windows actual
screen size with GetWindowRect(). From the main frames client rect and
the windows rect I can calculate the extra width and height of the
window borders. This I can add onto the height of my largest CFormView
and also the combined width of my two CFormViews (as they are setup 2
columns 1 row in the splitter).

The problem seems to be however that the CStatusBar in my SDI is not
taken into account by the GetWindowRect() calculation. Also the width
calculation I do does not include the width of the splitter bar, in fact
I have no idea how to find the width of this. NOTE: If you do a
GetClientRect() on the two CFormViews you get the same cumulative value
as the the GetClientRect() lookup on the main frame, therefore the
client rectangle as retrieved does not seem to take into account the
splitter bar either.

In summary. The partial solution to the problem is to use
GetTotalSize(), however this only works on a CFormView derived class.

David.

I think that if you use something like

RECT screen;

BOOL rv = SystemParametersInfo ( SPI_GETWORKAREA, 0, & screen, 0 );

you get a more accurate size of what you are using for your splitter
window.

I have found that including the size in CreateView gives a better result
than using SetRowInfo etc.

(I do find split windows a bit confusing sometimes. They seem to have a
mind of their own)
