OnDrawItemConstraint Question

Hello,

Copy this code to your application:

class CPropertyGridItemColorList : public CXTPPropertyGridItemColor
{
public:
    CPropertyGridItemColorList(const CString& strCaption, COLORREF clr)
        : CXTPPropertyGridItemColor(strCaption, clr)
    {
        SetFlags(xtpGridItemHasComboButton | xtpGridItemHasEdit);
        GetConstraints()->AddConstraint(_T("Red"), RGB(0xFF, 0, 0));
        GetConstraints()->AddConstraint(_T("Green"), RGB(0, 0xFF, 0));
        GetConstraints()->AddConstraint(_T("Blue"), RGB(0, 0, 0xFF));
    }

    virtual void OnInplaceButtonDown()
    {
        CXTPPropertyGridItem::OnInplaceButtonDown();  &nbs p;    
    }

    virtual void OnValueChanged(CString strValue)
    {
        for (int i = 0; i < GetConstraints()->GetCount(); i++)
        {
             CXTPPropertyGridItemConstraint* pContstraint = GetConstraints()->GetConstraintAt(i);
             if (strValue == pContstraint->m_strConstraint)
             {
                 CXTPPropertyGridItemColor::OnValueChanged(RGBToString(pConts traint->m_dwData));
                 return;
             }
        }
        CXTPPropertyGridItemColor::OnValueChanged(strValue);
    }
   
    void OnDrawItemConstraint(CDC* pDC, CXTPPropertyGridItemConstraint* pConstraint, CRect rc, BOOL bSelected)
    {
        CRect rcColor(rc.left + 1, rc.top + 1, rc.left + 19, rc.bottom - 1);
        pDC->FillSolidRect(rcColor, pConstraint->m_dwData);
        pDC->Draw3dRect(rcColor, 0, 0);

        rc.left += 20;
        CXTPPropertyGridItemColor::OnDrawItemConstraint(pDC, pConstraint, rc, bSelected);
       
    }

};

usage:

pSettings->AddChildItem(new CPropertyGridItemColorList(_T("BackColor"), clr));

Thank you...oleg

I solve my problem for your help

It works Great...
