Hello

Not a mouse, I want to change expression contents of these CExtBarButton by processing in the program.

Thanks,

Your code looks absolutely correct. You can use the CExtToolControlBar::CommandToIndex() method instead of the for() loop in your ScanCommandItems() method.

Hello.

I seem not to be able to ask you a question well.
Not dynamic, I want to change it into appointed CmdID from the program inside.
I seem to be able to do it by the following programs.
If there is the method that is better than this, please teach it

    CExtBarButton * pExtBarButton;
    pExtBarButton = ScanCommandItems( nGrpCmdID );
    if ( pExtBarButton != NULL ){
        CExtRibbonButton * pNodeGrid;
        pNodeGrid = (CExtRibbonButton *)pExtBarButton;
        pNodeGrid->SetCmdID ( ID_LINE3 , true , true );
    }

----------------------------------------------------------------

CExtBarButton * CMuRibbonBar::ScanCommandItems( UINT nCmdID )
{

    if( ! IsVisible() )
        return 0;

    INT nBtnsCount = GetButtonsCount();
    if( nBtnsCount == 0 )
        return 0;

    INT nUpdateBtnsCount = 0;
    bool bUpdateBar = false;
    for( INT nBtnIdx = 0; nBtnIdx < nBtnsCount; nBtnIdx++ )
    {
        CExtBarButton * pTBB = NULL;

        pTBB = ( ( CExtRibbonPage * )( this ) ) -> GetButton( nBtnIdx );
        ASSERT_VALID( pTBB );
        UINT nTbbCmdID = pTBB->GetCmdID( false );
        if(    nTbbCmdID != nCmdID )
            continue;
        return pTBB;
    } // for( INT nBtnIdx = 0; nBtnIdx < nBtnsCount; nBtnIdx++ )

    return NULL;
}

The ribbon bar buttons display exactly the same menus like toolbar buttons. If you need fully dynamic menus, then you can choose one of the following ways:

1) Change command tree nodes describing popup menu structure under ribbon bar’s button.

2) Make this menu containing only one command item and handle the CExtPopupMenuWnd::g_nMsgPrepareMenu (or CExtPopupMenuWnd::g_nMsgPrepareOneMenuLevel) registered windows message like demonstrated in the ProfUIS_Controls sample application. This will allow you to find a single command item in a popup menu, remove it and insert a set of other menu items instead.

Hello.

I know how to use __ECTN_TBB_SEPARATED_DROPDOWN| __ECTN_TBB_AUTOCHANGE_ID.

What I want to hear.
It was generated in the ribbon bar inside.
pTBB = new CExtBarButton

With pTBB, I want to operate a menu from the program side.

Please apply the __ECTN_TBB_SEPARATED_DROPDOWN|__ECTN_TBB_AUTOCHANGE_ID styles to the ribbon command tree node which represents the ribbon button with line widths menu. As a result, this button will automatically change its icon and its effective command part to the last invoked menu item’s icon and command identifier.
