有VC做一个特殊字符的选择控件

翻译|其它|编辑：郝浩|2007-08-20 09:18:31.000|阅读 1804 次

概述：

1.在 Office 里面有一个特殊字符的对话框

我们也自己做一个这个类似的控件来插入那些特殊字符.

2.说做就做,begin...........

用从 CStatic 派生一个新的类,我命名为 CStcImageFont,头文件如下.

#pragma once

// CStcImageFont

class CStcImageFont : public CStatic
...{
    DECLARE_DYNAMIC(CStcImageFont)

public:
    CStcImageFont();
    virtual ~CStcImageFont();

protected:
    DECLARE_MESSAGE_MAP()
public:
    afx_msg void OnPaint();
private:
    CDC        *m_dcFont ;
    CBitmap *m_bmFont ;
    int      m_iRowX ;
    int      m_iRowY ;
    int      m_iCurPos ;
    //垂直滚动条
    CScrollBar*        m_pScrollBar;
    CStringList     m_strList ;
    CRect           m_rClient ;
    CString  m_strSelText ;
    double     m_dXSpace ;
    double     m_dYSpace ;
public:
    void     SetRowXY(int iRowX , int iRowY ) ;
    int      GetRowX( void ) ;
    int      GetRowY( void ) ;
    void     SetCurPos(int iPos ) ;
    int      GetCurPos(void ) ;
    void     Init() ;
    CString  GetSelText(void) ;

    afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
    afx_msg void OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar);
    afx_msg void OnLButtonDblClk(UINT nFlags, CPoint point);
    afx_msg UINT OnNcHitTest(CPoint point);
};

实现文件如下 CPP

#include "stdafx.h"
#include "TestImageSymbol.h"
#include "StcImageFont.h"
#include ".stcimagefont.h"
