由于控件是也是窗口，用户可以调用CWnd: : SetFont指定新字体。该函数用一个Cfont指针，要保证在控件撤消之前不能撤消字体对象。下例将下压按钮的字体改为8点Arial字体：<Br>
//Declare font object in class declaration (.H file ).<Br>
private : Cfont m_font<Br>
// Set font in class implementation (.Cpp file ). Note m_wndButton is a<Br>
//member variable added by ClassWizard.DDX routines hook the member<Br>
//variable to a dialog button contrlo.<Br>
BOOL CSampleDialog : : OnInitDialog ( )<Br>
{<Br>
…<Br>
//Create an 8-point Arial font<Br>
m_font . CreateFont (MulDiv (8 , -pDC<Br>
—> GetDeviceCaps(LOGPIXELSY) ,72). 0 , 0 , 0 , FW_NORMAL , 0 , 0,0, ANSI_CHARSER, OUT_STROKE_PRECIS ,<Br>
</Br>
CLIP_STROKE _PRECIS , DRAFT _QUALITY<Br>
VARIABLE_PITCH ｜FF_SWISS, _T("Arial") )<Br>
</Br>
//Set font for push button .<Br>
m_wndButton . SetFont (&m _font )<Br>
