CDC::DrawText Not doing as it's told

softwaremonkey

Guys, I have a problem with CDC::DrawText() and I have been sitting here wasting away my Sunday trying to figure it out. The problem is that it does not draw the text in the position I expect it to be. The following code is supposed to draw a rectangle, then draw the text in the box, using the style (DT_LEFT, DT_CENTER or DT_RIGHT).

CBrush brush(m\_background\[nIndex\]);
CBrush\* pOldBrush = pDC->SelectObject(&brush);
pDC->SetBkColor(m\_background\[nIndex\]);
pDC->SetBkMode(OPAQUE);
pDC->SelectStockObject(NULL\_PEN);
pDC->Rectangle(m\_hitRect);
pDC->SelectObject(pOldBrush);
pDC->SetBkMode(TRANSPARENT);
pDC->DrawText(txt,m\_hitRect, m\_nStyle | DT\_SINGLELINE | DT\_VCENTER);

The text appears in the box (but not in the correct position) when I use DT_CENTER or DT_RIGHT but is not drwn at all with DT_LEFT (I think its outside the rect). Please help, I really should be cutting the grass! :-D Tony

Check the values in m_hitRect, I don't think we can guess what they are. [edit]It is also worth checking the return value from the DrawText() call to verify that it did what you expect.[/edit]

You don't show the values of variables so it's hard to guess. If you strip it down and hardcode values it works fine...

CString txt = \_T("This is the text!");
CRect m\_hitRect(10,10,200,40);
//CBrush brush(RGB(0xFF,0x00,0x00));//(m\_background\[nIndex\]);
//CBrush\* pOldBrush = dc.SelectObject(&brush);
//dc.SetBkColor(RGB(0x80,0x80,0x80));
//dc.SetBkMode(OPAQUE);
//dc.SelectStockObject(NULL\_PEN);
dc.Rectangle(m\_hitRect);
//dc.SelectObject(pOldBrush);
//dc.SetBkMode(TRANSPARENT);
dc.DrawText(txt,m\_hitRect, DT\_LEFT | DT\_SINGLELINE | DT\_VCENTER);

Hi thanks for the reply. I figured out what it was, and as usual its something dumb and not in the area I was looking in. A long, long time ago I had padded out the right hand side of the string with spaces (not sure why I did this). Anyway, as you can imagine, this would totally screw up the justification. Oh well, that grass wont mow itself :laugh: Thanks
