Remarks

The ribbon color button displays a color bar when a user presses it. By default, this color bar contains a color selection palette called the regular color area. Optionally, the color bar can display an Automatic button, which allows the user to select a default color, and an Other button, which displays a popup color palette that contains additional colors.

Example

The following example demonstrates how to use various methods in the CMFCRibbonColorButton class. The example shows how to construct a CMFCRibbonColorButton object, set the large image, enable the Automatic button, enable the Other button, set the number of columns, set the size of all the color elements that appear on the color bar, add a group of colors to the regular color area, and specify a list of RGB values to display in the document color area. This code snippet is part of the Draw Client sample.

    // Create the "Paper Color" button
    CMFCRibbonColorButton* pBtnPaperColor = new CMFCRibbonColorButton(ID_VIEW_PAPERCOLOR, _T("Paper Color\ng"), TRUE, 13, 1);
    pBtnPaperColor->SetAlwaysLargeImage();
    pBtnPaperColor->EnableAutomaticButton(_T("&Automatic"), RGB(255, 255, 255));
    pBtnPaperColor->EnableOtherButton(_T("&More Colors..."), _T("More Colors"));
    pBtnPaperColor->SetColumns(10);
    pBtnPaperColor->SetColorBoxSize(CSize(17, 17));
    // CList<COLORREF,COLORREF> m_lstMainColors
    pBtnPaperColor->AddColorsGroup(_T("Theme Colors"), m_lstMainColors, TRUE);
    // CList<COLORREF,COLORREF> m_lstAdditionalColors
    pBtnPaperColor->AddColorsGroup(_T(""), m_lstAdditionalColors, FALSE);
    // CList<COLORREF,COLORREF> m_lstStandardColors
    pBtnPaperColor->AddColorsGroup(_T("Standard Colors"), m_lstStandardColors, TRUE);
    CList<COLORREF,COLORREF> lstColors;
    lstColors.AddTail(RGB(255,0,0));
    lstColors.AddTail(RGB(0,255,0));
