After obtaining the information for each type of font, we create a font using this information by calling
function CFont::CreateFontIndirect(…). The addresses of these font objects are stored in array
CGDIView::m_ptrFont.
In function CGDIView::OnDraw(…), the face names of all fonts are output to the client window:
void CGDIView::OnDraw(CDC* pDC)
{
CGDIDoc *pDoc=GetDocument();
ASSERT_VALID(pDoc);
CString szStr;
CFont *ptrFtOld;
CFont *ptrFont;
int nYPos;
int i;
nYPos=10;
szStr.Format("Number of raster fonts: %d", m_nFontCount[0]);
pDC->TextOut(10, nYPos, szStr);
nYPos+=20;
ptrFont=m_ptrFont;
for(i=0; iGetSafeHandle() != NULL);
ptrFtOld=pDC->SelectObject(ptrFont);
pDC->TextOut(10, nYPos, (m_lpLf[0]+i)->lfFaceName);
nYPos+=(m_lpLf[0]+i)->lfHeight;
pDC->SelectObject(ptrFtOld);
ptrFont++;
}
nYPos+=20;
szStr.Format("Number of vector fonts: %d", m_nFontCount[1]);
pDC->TextOut(10, nYPos, szStr);
nYPos+=20;
