Printable View
Hello
MFC+SDI application
I want to put multiline text on the view.
User enters text into edit box and then clicks insert comments button.
Comments has to be printed over the defaults Comments place.
If text is more than that fits to a A-4 page setup then it has to be wrapped and to be in multiline
How to do this?
I am using CDC's function DrawText with format set as DT_TOP|DT_LEFT
Use a scrolling view, not a CView
//Set up your page, scroll sizes in OnInitialUpdate
Helper fxn - if you are using A4 paper change the paper size in this fxnCode:void CScrollTextView::OnInitialUpdate()
{
CScrollView::OnInitialUpdate();
CDC* pDC = GetDC();
ASSERT_VALID(pDC);
CRect rcPrint;
//getMargins() is inline - returns 50, 50, 50, 50 Rect
// 1/2" margins
ASSERT(getPrintRect(pDC, rcPrint, getMargins()));
ReleaseDC(pDC);
//Total print area
CSize sizeTotal(rcPrint.Width(), rcPrint.Height());
//A scrolling page will be 1/2 the total print area
CSize sizePage(sizeTotal.cx / 2, sizeTotal.cy / 2);
//A line scroll will be 25th of the total print area
CSize sizeLine(sizeTotal.cx / 25, sizeTotal.cy / 25);
SetScrollSizes(MM_TEXT, sizeTotal, sizePage, sizeLine);
}
//An example OnDraw()Code:BOOL CScrollTextView::getPrintRect(CDC* pDC, CRect & rcPrint,
const CRect & rcLoEnglishMargins)
{
ASSERT_VALID(pDC);
//Logical inches
int logX = pDC->GetDeviceCaps(LOGPIXELSX);
int logY = pDC->GetDeviceCaps(LOGPIXELSY);
//8.5 X 11 paper
CRect rcPage(0, 0, MulDiv(logX, 17, 2), logY * 11);
//Printable portion of page
rcPrint.left = rcPage.left + MulDiv(rcLoEnglishMargins.left, logX, 100);
rcPrint.top = rcPage.top + MulDiv(rcLoEnglishMargins.top, logY, 100);
rcPrint.right = rcPage.right - MulDiv(rcLoEnglishMargins.right, logX, 100);
rcPrint.bottom = rcPage.bottom - MulDiv(rcLoEnglishMargins.bottom, logY, 100);
if (pDC->IsPrinting())
{
//Adjust for physical offset of printer. Usually this shifts
//toward left and top. Calling fxn doesn't need to adjust
//viewport origin
int xOffset = pDC->GetDeviceCaps(PHYSICALOFFSETX);
int yOffset = pDC->GetDeviceCaps(PHYSICALOFFSETY);
rcPrint.OffsetRect(-xOffset, -yOffset);
}
else
//WYSIWYG but without the margins
rcPrint.OffsetRect(-rcPrint.left, -rcPrint.top);
return TRUE;
}
Hope this helps.Code:void CScrollTextView::OnDraw(CDC* pDC)
{
CRect rcPrint;
// 1/2" margins
ASSERT(getPrintRect(pDC, rcPrint, getMargins()));
CFont font;
font.CreatePointFont(120, _T("Times New Roman"), pDC);
CFont* pOldFont = pDC->SelectObject(&font);
CString strText = _T("Now is the time for all good men to come to the"
" aid of their country. This is the mantra used in beginning typing"
" class to train the brain to distinguish right from left and "
" develop speed with accuracy.");
pDC->DrawText(strText, &rcPrint, DT_WORDBREAK);
pDC->SelectObject(pOldFont);
font.DeleteObject();
}
