Dear ProfUIS-Team,
there seems to occur some strange behaviour with your Ribbon(MDI) demo. It could be reproduced without code modifications for versions 2.82 and 2.85.
Opening the about-dialog (which is obviously meant to be modal) and leaving the focus of this dialog, i.e. moving mouse pointer outside, you can wheel-scroll through the ribbon tabpages. Also, if being fast enough, you can catch some focus within the ribbonbar, i.e. some of the buttons appear to be active for a short time.
As I can’t imagine that this is an intended feature, I’d like to let you know.
Best regards,
Martin

Thank you for reporting this issue. We fixed it in the following method:
bool CExtRibbonBar::OnRibbonProcessMouseWheel( UINT fFlags, short zDelta, CPoint point )
{
ASSERT_VALID( this );
fFlags;
point;
if( GetSafeHwnd() == NULL )
return false;
if( zDelta == 0 )
return false;
if( ! RibbonPage_ExpandedModeGet() )
return false;
if( m_bFlatTracking )
return false;
if( ( GetStyle() & WS_DISABLED ) != 0 )
return false;
CWnd * pWnd = GetParent();
if( pWnd != NULL
&& ( pWnd->GetStyle() & WS_DISABLED ) != 0
)
return false;
INT nIndex, nCount = RibbonTabPageButton_GetCount();
if( nCount <= 1 )
return false;
HWND hWndFocus = ::GetFocus();
if( hWndFocus != NULL
&& ( hWndFocus == m_hWnd
|| ::IsChild( m_hWnd, hWndFocus )
)
)
return false;
bool bNext = ( int(zDelta) < 0 ) ? true : false;
CExtRibbonButtonTabPage * pNewSelTBB = NULL;
bool bSelPassed = false;
for( nIndex = 0; nIndex < nCount; nIndex ++ )
{
CExtRibbonButtonTabPage * pTBB = RibbonTabPageButton_GetAt( nIndex );
ASSERT_VALID( pTBB );
if( pTBB->IsSelectedRibbonPage() )
{
bSelPassed = true;
continue;
}
if( ! pTBB->OnQueryFlatTrackingEnabled() )
continue;
if( bSelPassed )
{
if( bNext )
{
if( pNewSelTBB == NULL )
{
pNewSelTBB = pTBB;
break;
}
}
else
break;
} // if( bSelPassed )
else
{
if( bNext )
continue;
pNewSelTBB = pTBB;
} // else from if( bSelPassed )
} // for( nIndex = 0; nIndex < nCount; nIndex ++ )
if( pNewSelTBB == NULL )
return false;
Invalidate();
if( m_bFlatTracking )
{
m_bFlatTracking = false;
OnFlatTrackingStop();
} // if( m_bFlatTracking )
_UpdateFlatTracking( false );
INT nPageIndex, nPageCount = RibbonTabPageButton_GetCount();
for( nPageIndex = 0; nPageIndex < nPageCount; nPageIndex ++ )
{
CExtRibbonButtonTabPage * pTabPageTBB = RibbonTabPageButton_GetAt( nPageIndex );
ASSERT( pTabPageTBB );
pTabPageTBB->SetHover( false );
pTabPageTBB->ModifyStyle( 0, TBBS_PRESSED|TBBS_CHECKED );
} // for( . . .
_UpdateHoverButton( CPoint(-1,-1), false );
pNewSelTBB->OnDeliverCmd();
return true;
}
