Has anyone used MfcGridCtrl, if you want to use different colors for different characters in a cell, is there any way?

MfcGridCtrl is said to be the best grid

ayasakura

To achieve your requirements, you must modify the setting text function in gridctrl
An additional parameter must be added to pass the font color you want in the past. It is estimated that it will be more troublesome to modify
You must be familiar with gridctrl class

ayasakura

I think it is really troublesome to modify
The GridCtrl class itself is very cumbersome. To realize the function you mentioned, it is not clear in a sentence or two.
So everyone can't answer
I think it’s better to write a CWnd to draw a grid and fill CRichEdit in each cell
You can download this MultilineListControl on codeproject to see

zgw716

Upstairs is right, but filling RichEdit in each cell takes up resources.
Let me see what you said MultilineListControl

westevil

he is right.

Why don't you redraw on the basis of listctrl?
That's low resources.

gkbbao

BOOL CGridCellBase::Draw(CDC* pDC, int nRow, int nCol, CRect rect, BOOL bEraseBkgnd /*=TRUE*/)
{
.....
  //pDC->SetTextColor(); modify the color of the character, add your code here
   DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);//Text output

    pDC->RestoreDC(nSavedDC);

    return TRUE;
}

The upstairs seems to have used the MFCGridCtrl control, but your method just changed the font color of the entire Cell.
I want to use different colors for different characters in a cell (multi-line display) (for example, the searched characters use red).

I spy a program written by others (implement the function I said), can the experts see how others do it?

He uses WM_CTLCOLORBTN for message reflection to modify the background color of the control
This cannot meet your requirements in MFCGridCtrl
Try the method I said for yourself
Replace this code
CString strText = GetText();
CString strTemp = strText.Left(1);
if (strTemp == "1")
{
CSize szText = pDC->GetTextExtent( strTemp );
for (int x = 0; x <strText.GetLength(); x++)
{
strTemp = strText.Mid(x, 1);
rect.left += szText.cx*x;
if (x% 2)
{
pDC->SetTextColor( 0x00ff0000);
} else
{
pDC->SetTextColor( 0x0000ff00);
}

DrawText(pDC->m_hDC, strTemp, -1, rect, GetFormat() | DT_NOPREFIX);
}
} else DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);
   


The original
DrawText(pDC->m_hDC, GetText(), -1, rect, GetFormat() | DT_NOPREFIX);

See if the characters in the demo are displayed in color?
