Basic concept of splitter windows is to have resizable panes.
But dont know what to do the way you want them to be!

I found the right solution
for implementation re- unchangeable size of splitter panes.
It is useful to know.
Sometimes it is needed.

Use instead of CSplitterWnd
class CSplitterWndNRS (NoReSizeable)

class CSplitterWndNRS : public CSplitterWnd
{
public:
virtual int HitTest(CPoint pt) const {return 0;};
};

Derive a class from CSplitterWnd. In your header file, put


BOOL m_bLockedSplBars;

inline void SetSplBarLock(const BOOL bLocked) {m_bLockedSplBars = bLocked;}
inline BOOL GetSplBarLock() const {return m_bLockedSplBars;}




Use the class wizard to make handlers for WM_LBUTTONDOWN, WM_MOUSEMOVE, and WMSETCURSOR. In the cpp file, add code to the handlers as below.


// --------------------------------------------------------------------------
void CSplWndFixed::OnLButtonDown(UINT nFlags, CPoint point)
{
if (m_bLockedSplBars)
{ // CWnd doesn't do splitter bars.
CWnd::OnLButtonDown(nFlags, point);
}
else
{ // CSplitterWnd handles splitter bars.
CSplitterWnd::OnLButtonDown(nFlags, point);
}
}


// --------------------------------------------------------------------------
void CSplWndFixed::OnMouseMove(UINT nFlags, CPoint point)
{
if (m_bLockedSplBars)
{ // CWnd doesn't do splitter bars.
CWnd::OnMouseMove(nFlags, point);
}
else
{ // CSplitterWnd handles splitter bars.
CSplitterWnd::OnMouseMove(nFlags, point);
}
}


// --------------------------------------------------------------------------
BOOL CSplWndFixed::OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message)
{
if (m_bLockedSplBars)
{ // CWnd doesn't do splitter bars.
return CWnd::OnSetCursor(pWnd, nHitTest, message);
}
else
{ // CSplitterWnd handles splitter bars.
return CSplitterWnd::OnSetCursor(pWnd, nHitTest, message);
}
}




Initialize m_bLockedSplBars in your constructor or elsewhere.
