Hello

ttp://profuis0.tripod.com/20060713/image01.jpg

CExtControlBar is the present.
Is it connected to the left?
Is it connected to the right?
Is it connected to the top?
Is it connected to the bottom?

I want to examine it.

It is not examined in IsDockedAtRight, IsDockedAtLeft well.

Thanking you in advance.

Do you set it in Postion at the time of MiniDock?

Hello

Will contents of a question be illegible?

et us assume we have the following:

CExtControlBar * pSomeBar = . . .
CFrameWnd * pMainFrame = . . .
CFrameWnd * pParentFrame = pSomeBar->GetParentFrame();

Then we can compute this:

bool bSingleFloatingBarInItsMiniFrame = pSomeBar->IsFloating();
    if( bSingleFloatingBarInItsMiniFrame )
        return; // the pSomeBar bar is alone in its floating mini frame window
    if( pParentFrame == pMainFrame )
        return; // the pSomeBar bar is docked inside the main frame window

Now we know that the pSomeBar bar is inside a complex mini frame window. Its parent window is an CExtDockBar object. But we need to find the nearest CExtDockDynBar parent window which can be either a dynamic horizontal/vertical bar container or a tabbed bar container:

CWnd * pParentWnd = pSomeBar->GetParent();
CExtDockDynBar * pDynDockBar = NULL;
    for( ; pParentWnd != pParentFrame; pParentWnd = pParentWnd->GetParent() )
    {
            pDynDockBar = DYNAMIC_DOWNCAST( CExtDockDynBar, pParentWnd );
            if( pDynDockBar != NULL)
                break;
    }
    if( pDynDockBar == NULL )
        return;

You should not face a situation when the pDynDockBar is NULL. You may come across this only when the resizable bar is being drag-and-dropped.

Now we should check whether the pDynDockBar window is a dynamic tabbed bar container:

CExtDockDynTabBar * pTabbedGroupContainer = DYNAMIC_DOWNCAST( CExtDockDynTabBar, pDynDockBar );
    if( pTabbedGroupContainer != NULL )
        return; // this is not interesting for us

Now we know that the

pDynDockBar

window is a container for one row or one column of bars and we can walk though all the bars in this container and check where each bar in this container is:

// first check the horizontal or vertical orientation
DWORD dwWndID = (DWORD)pDynDockBar->GetDlgCtrlID();
bool bContainerOrientationIsHorizontal =
        ( dwWndID == AFX_IDW_DOCKBAR_TOP || dwWndID == AFX_IDW_DOCKBAR_BOTTOM ) ? true : false;
 
// this pre-processor function is needed for the next step
#if _MFC_VER >= 0x710
    #define __ARRAY_ENTRY_IS_PLACEHODLER_MARKER__( __CB__ )         ( ( DWORD_PTR(__CB__) ) <= 0x0FFFF )
#else
    #define __ARRAY_ENTRY_IS_PLACEHODLER_MARKER__( __CB__ )         ( ( HIWORD(__CB__) ) == 0 )
#endif

// now we will walk through all the bars in the container
INT nIndexInArray, nCountOfArrayEntries = pDynDockBar->m_arrBars.GetSize();
    for( nIndexInArray = 0; nIndexInArray < nCountOfArrayEntries; nIndexInArray ++ )
    {
        CExtControlBar * pBar = (CExtControlBar *)pDynDockBar->m_arrBars[nIndexInArray];
        if( pBar == NULL || __ARRAY_ENTRY_IS_PLACEHODLER_MARKER__( pBar ) )
            continue; // pBar is not a valid pointer
        //
        //
        // You can analyze pBar here and detect which of your bars are
        // at left/top/right/bottom relative to your other bars
        //
        //
    }
