【CSplitterWnd技巧二】使分割窗口不能改变大小

作者：周焱

有时候，需要保持分割窗口中每个小窗口的尺寸或者比例，不允许用户拖动分割条。我考虑了有两种方法可以实现。效果如下，鼠标在分割条上，没有出现可以改变大小的箭头。

方法1:
================================================
//CMySplitter.h
#pragma once

#include "stdafx.h"

class CMySplitter:public CSplitterWnd
{
 DECLARE_DYNAMIC(CMySplitter)
public:
 DECLARE_MESSAGE_MAP()
protected:

 //重载进行非客户区鼠标测试函数
 afx_msg UINT OnNcHitTest(CPoint point);
};
================================================
//CMySplitter.cpp
#include "Cmysplitter.h"

IMPLEMENT_DYNAMIC(CMySplitter,CSplitterWnd)

BEGIN_MESSAGE_MAP(CMySplitter,CSplitterWnd)
 ON_WM_NCHITTEST()
END_MESSAGE_MAP()

UINT CMySplitter::OnNcHitTest(CPoint point)
{
 //返回HTNOWHERE...
 return HTNOWHERE;
}
================================================

方法2：
================================================
//CMySplitter.h
#pragma once
#include "stdafx.h"

class CMySplitter : public CSplitterWnd
{
 DECLARE_DYNCREATE(CMySplitter)

protected:
 afx_msg void OnLButtonDown(UINT nFlags, CPoint point);
 afx_msg BOOL OnSetCursor(CWnd* pWnd, UINT nHitTest, UINT message);
 afx_msg void OnMouseMove(UINT nFlags, CPoint point);

 DECLARE_MESSAGE_MAP()
};
================================================
//CMySplitter.cpp

#include "CMySplitter.h"

IMPLEMENT_DYNCREATE(CMySplitter, CSplitterWnd)

BEGIN_MESSAGE_MAP(CMySplitter, CSplitterWnd)
