Dear Support,


I would like to create an owner-draw CExtGridCell. I have overridden the OnPaintForeground method, but cannot seem to get anything in this cell. The code is below. Any suggestions would be much appriciated.



class
{
string m_strErrorWarningTooltip;
string m_strAoTooltip;
VRApproOrientation::ERROR_TYPE m_nErrType;
 
CExtBitmap m_bmpAoNoError;
CExtBitmap m_bmpAoWarning;
CExtBitmap m_bmpAoError;
CExtBitmap m_bmpLandscapeA1Away;
CExtBitmap m_bmpLandscapeA1Toward;
CExtBitmap m_bmpPortraitA1Away;
CExtBitmap m_bmpPortraitA1Toward;
CExtBitmap m_bmpRighty;
CExtBitmap m_bmpLefty;
 VRCellErrWarnAndAo : public CExtGridCellint m_nAoId;
public
DECLARE_SERIAL( VRCellErrWarnAndAo );

VRCellErrWarnAndAo(CExtGridDataProvider * pDataProvider = NULL);

};

The lines of code in your message are messed up. Please do not use MS Word for copying text from and paste it here.

We looked into the source code of the VRCellErrWarnAndAo::OnPaintForeground() method you sent us via e-mail. It uses zero values as top/left corner of the grid cell. This is not correct. Please use the rcCell method parameter. It describes cell location in the client coordinates of the grid window. So, the following code:

   dc.MoveTo(0,0);
            dc.LineTo(5,5);

Should be replaced with the following:
   dc.MoveTo( rcCell.left, rcCell.top );
            dc.LineTo( rcCell.left + 5, rcCell.top + 5 );
