Multiline text on View

[d0153030]

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

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);
}

Helper fxn - if you are using A4 paper change the paper size in this fxn

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;
}

//An example OnDraw()

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();	
}

Hope this helps.
