This is MFC version of grid I originally wrote in OWL. All about grid is in PageWnd.h (cpp) file (which does not mean it is too long). CPageWnd provides public members for getting/setting cell text, color, alignment and font, column width, row height and similar. It is easy to derive CPageWnd and add additional functionality. This code is build with Visual C++ 5.0 (it should work with 4.x version). To integrate in existing project just insert PageWnd.cpp file in your project. How to use CPageWnd find is shown in TestPageView.cpp. If you are interested for OWL version of grid, e-mail me.

  • Grid Control in C?

    Is it possible to implement a grid control in plain C rather than C++ or MFC and if so how is it done?

  • Suggests and paint errors

    You class is nice but if you create GDIs object to each cell and hold all of them created, if you have many and many
    cells the systems resources will go down because the GDI resources (pens, fonts, brushes, etc) are limited !
    You can hold to each cell only the infomation about the GDI objects like font typeface, size, color etc, brush color, etc and create them when you will paint the cell and after the cell paint process, free then. I know that this process is a little bit slower but this is the better solution to your case.

    The paint errors are not logical errors. The problem are when you use SelectObject CDC function, you must hold the returned object pointer and call SelectObject again with the held object before release the dc. If you don't do this, even if you destroy the objects before you program exits (I see that you are doing this!) the Windows will not free the object because it was selected in a dc but not deselected !!

  • Error & Fix

     1. Mark cell A1 as the active cell

     2. Scroll to right (by mouse) to hide current active cell

     3. Click on any cell (let's say B2)

     4. Notice that the old col/row markers are not cleared (i.e., Still shown in BOLD).


    Fix:

     1. In function MarkActiveCell() do:

     ...

     if(fprev)

     {

        MarkHeader(false); //This is new place of this call   

        if(m_pScrollData->XPos < m_colEditEx && m_pScrollData >YPos < m_rowEditEx)

        {

           CPen inactivePen(PS_SOLID, 2, GetCellColor(m_rowEditEx, m_colEditEx));

           dc.SelectObject(&inactivePen);

           CRect r(m_EditRect.left + 2, m_EditRect.top + 2, m_EditRect.right, m_EditRect.bottom);

           dc.Rectangle(r);

           //MarkHeader(false); // This is old place of this call

        }

     }

     ...


     2. Retype function MarkHeader() as follows :

    void CPageWnd::MarkHeader(bool mark)

    {

    	CRect rowRect(0, m_EditRect.top, m_width[0], m_EditRect.bottom);

    	CRect colRect(m_EditRect.left, 0, m_EditRect.right, m_height[0]);


    	CClientDC dc(this);


    	SetCellFont(m_rowEditEx, 0, *m_pDefFont);

    	SetCellFont(0, m_colEditEx, *m_pDefFont);


    	SetCellFont(m_rowEdit, 0, *m_pDefFontBold);

    	SetCellFont(0, m_colEdit, *m_pDefFontBold);


    	if(!mark)  {

    		if(m_rowEditEx > m_pScrollData->YPos && m_rowEditEx < m_pScrollData->YPos + m_pScrollData->YPage)

    			dc.DrawEdge(rowRect, BDR_RAISEDINNER, BF_RECT | BF_MIDDLE);


    		CellEntry(dc, m_rowEditEx, 0, rowRect);

    		

    		if(m_colEditEx > m_pScrollData->XPos && m_colEditEx < m_pScrollData->XPos + m_pScrollData->XPage)

    			dc.DrawEdge(colRect, BDR_RAISEDINNER, BF_RECT | BF_MIDDLE);    


    		CellEntry(dc, 0, m_colEditEx, colRect);

    	}

    	else {

    		dc.DrawEdge(rowRect, EDGE_RAISED ,  BF_RECT | BF_MIDDLE);  //BDR_RAISED  

    		CellEntry(dc, m_rowEdit, 0, rowRect);

    		

    		dc.DrawEdge(colRect, EDGE_RAISED,  BF_RECT | BF_MIDDLE); //BDR_RAISED    

    		CellEntry(dc, 0, m_colEdit, colRect);

    	}

    }
