Hello,

i've follow code.
    CXTPDockingPaneTabbedContainer* pContainer = GetParentContainer(pWnd);
    if (pContainer && pContainer->GetPanes().GetCount() > 1)
        {
        CXTPDockingPane* pSelected = dynamic_cast<CXTPDockingPane*>(pContainer->GetPanes().GetHead());

after dynamic cast i get error
Eine Ausnahme (erste Chance) bei 0x10227827 (msvcr71d.dll) in Lasal2.exe: 0xC0000005: Zugriffsverletzung-Leseposition 0x00000004.
Eine Ausnahme (erste Chance) bei 0x7c812aeb (kernel32.dll) in Lasal2.exe: Microsoft C++ exception: __non_rtti_object @ 0x0012f20c.

Hi Oleg,

CXTPDockingPaneTabbedContainer *GetParentContainer(CWnd* pParentWnd)
{
    if (pParentWnd == NULL || pParentWnd->GetSafeHwnd() == NULL) // no Window attached
        return NULL;

    while (pParentWnd != NULL)
    {
        CXTPDockingPaneTabbedContainer *pContainer = DYNAMIC_DOWNCAST(CXTPDockingPaneTabbedContainer, pParentWnd);
        if (pContainer)
            return pContainer;
        pParentWnd = pParentWnd->GetParent();
    }
    return NULL;
}

Hi Oleg,

After i add this, it will be work.

class CExXTPDockingPane : public CXTPDockingPane
{
public:
    CExXTPDockingPane(CXTPDockingPaneLayout* pLayout) : CXTPDockingPane(pLayout)
    { }
};

class CExDockingPaneManager : public CXTPDockingPaneManager
{
public:
    CXTPDockingPaneLayout *GetLayoutCurrent()        { return m_pLayout; }

    virtual CXTPDockingPaneBase *OnCreatePane(XTPDockingPaneType type, CXTPDockingPaneLayout* pLayout)
    {
        if (type == xtpPaneTypeDockingPane)
        {
            return new CExXTPDockingPane(pLayout);
        }
        return __super::OnCreatePane(type, pLayout);
    }
};

Hi Oleg,

i see rtti is not activated in Tookit DLL.
Think, this is the problem.

Hi,

You can use C style cast. CXTPDockingPaneTabbedContainer always has only CXTPDockingPane:

CXTPDockingPane* pSelected = (CXTPDockingPane*)pContainer->GetPanes().GetHead());

or if you need selected:

CXTPDockingPane* pSelected = pContainer->GetSelected()
