CDC中的竖排文本?


在OnDraw成员函数中我想让文本竖直对齐,但CDC类似乎不支持该处理
A:如果你的竖直对齐是指旋转文本的话,下面的代码会对你有帮助: 该代码检
查一个Check box控制,查看文本是否需要旋转.


// m_pcfYTitle is a Cfont* to the selected font.
// m_bTotateYTitle is a bool (==TRUE if  rotated)

void CPage1::OnRotateytitle()
{
LOGFONT lgf;
m_pcfYTitle->GetLogFont(&lgf);
m_bRotateYTitle=
        ((Cbutton*)GetDlgItem(IDC_ROTATEYTITLE))->GetCheck()>0;

// escapement is reckoned clockwise in 1/10ths of a degree:
lgf.lfEscapement=-(m_bRotateYTitle*900);
m_pcfYTitle->DeleteObject();

m_pcfYTitle->CreateFontIndirect(&lgf);
DrawSampleChart();
}
注意如果你从CFontDialog中选择了不同的字体,你应该自己设定LOGFONT的

lfEscapement成员.将初始化后的lfEscapement值传到CFontDialog中.

A2:还有一段代码可参考:

LOGFONT  LocalLogFont;

strcpy(LocalLogFont.lfFaceName, TypeFace);

LocalLogFont.lfWeight = fWeight;
LocalLogFont.lfEscapement = Orient;
LocalLogFont.lfOrientation  = Orient;

if (MyFont.CreateFontIndirect(&LocalLogFont))
   {
   cMyOldFont = cdc->SelectObject(&MyFont);
   }
