菜鸟问题（关于ondraw)

[xingliwei]

建立多文档筐架后在Cxlw01view.cpp的ondraw中加入如下代码
switch(m_nFlagFont=1)
{
case 1:
LOGFONT logFont;
logFont.lfHeight=3;
logFont.lfWidth=0;
logFont.lfEscapement=4;
logFont.lfWeight=FW_MEDIUM;
logFont.lfItalic=0;
logFont.lfUnderline=0;
logFont.lfStrikeOut=0;
logFont.lfCharSet=ANSI_CHARSET;
logFont.lfOutPrecision=OUT_DEFAULT_PRECIS;
logFont.lfClipPrecision=CLIP_DEFAULT_PRECIS;
logFont.lfQuality=PROOF_QUALITY;
logFont.lfPitchAndFamily=VARIABLE_PITCH|FF_ROMAN;
strcpy(logFont.lfFaceName,"Times New Roman");
UINT position=0;
CClientDC dc(this);
for(int x=0;x<8;x++)
{
logFont.lfHeight=16+(x*8);
CFont font;
font.CreateFontIndirect(&logFont);
CFont* oldFont=dc.SelectObject(&font);
position+=logFont.lfHeight;
dc.TextOut(20,position,"Test Font Size");
dc.SelectObject(oldFont);
}
}
然后建了个子菜单，在响应函数中加入如下代码：
void CXlw01View::OnMenuitem32771()
{

// TODO: Add your command handler code here
/////////////////////////////////////////////////////////////
m_nFlagFont=1;
////////////////////////////////////////////////////////////////

}

想达到点菜单即显示的功能，怎么不好用，大家给解答一下

子菜单响应函数改为：
void CXlw01View::OnMenuitem32771()
{

// TODO: Add your command handler code here
/////////////////////////////////////////////////////////////
m_nFlagFont=1;
Invalidate();
////////////////////////////////////////////////////////////////

}
