I know how to set separator position. I need to catch separator position changed event.
I can call function from views OnSize functions, but I would like to use better solution.

There is no such "event"/message.
Handle WM_SIZE, then use CSplitterWnd::SetColumnInfo/SetRowInfo followed by CSplitterWnd::RecalcLayout

I try

Code:

---

BOOL CChildFrame::PreTranslateMessage(MSG *pMsg)
{
    switch(pMsg->message)
    {
    case WM_SIZE:
        MessageBox("");
        break;
    }

    return CMDIChildWnd::PreTranslateMessage(pMsg);

---

But MessageBox appear only when window created. It does not work even when I resize window. What i did wrong?

What does PreTranslateMessage have to do with your splitter? :confused:
Why are you using it?
You have to directly handle WM_SIZE message!

I do not understand what means 'directly handle WM_SIZE message'.
I thought it means do not use MESSAGE_MAP and OnSize and use Win32 ways. What means 'directly handle message'?

It means:

1. GET RID OF PreTranslateMessage
2. Implement message handler for WM_SIZE

What did I do.

Code:

---

BEGIN_MESSAGE_MAP(CChildFrame, CMDIChildWnd)
    ON_WM_SIZE()
END_MESSAGE_MAP()


void CChildFrame::OnSize(UINT nType, int cx, int cy)
{
    CMDIChildWnd::OnSize(nType, cx, cy);
    //...

---

But OnSize called only when framewnd is changing size. It does not called when separators changed position.

Yes! And AFAIR it is exactly what you wanted!

I am sorry for my English. Probably I explained the problem poorly.
1. Separator changed postition - call function which calculate where is locate separators relativity them clients. For example 0.5 - in the middle.
2. When framewnd sizing separator get new positions by calculated values multiplied by new clients dimensions.

Your English is pretty good (much better than mine)!
But your problem explanation is very poor.

As for 1. and 2.... I already wrote you what to do in the post#6:

I know how to solve 2. And it works.
Do you mean to handle WM_SIZE in view? I understand it will work. But I am trying to catch event in framewnd, and do not call dynamic_cast<CChildFrame *>(GetParentFrame())->calculate() from all views. Do you mean this?

I already wrote you in another thread what you could do

Thanks.
