DoPropExchange DockingPane Taskpanel

Hi,

i use the CXTPTaskPanel as childwindow in CXTPDockingPane.
Now, when i use PaneManager.SetLayout after a successful Layout->LoadFromFile
the following problem occurs:

my first trial:
creating a taskpanel in CXTPDockingPaneManager::OnCreatePane
and calling the dockingpanes attach method, the setparent message in the attach method failed (i know the dockingpanes copy-method sets the child handle pointer to 0; there i destroy and create new the taskpanel). Seems that the dockingpane is not ready.


second trial:
i create my panel on OnDockingPaneNotify/XTP_DPN_SHOWWINDOW. then the DoPropExchange-method is not called to restore my taskpanelgroupitems.


Please help with ideas.

Thanks in advance

i read the nuber of panes from xml so I don't know how many panes/panels i have to create. So i overwrote the Clone-method:

CXTPDockingPaneBase* MyXTPDockingPane::Clone(CXTPDockingPaneLayout* pLayout, CXTPPaneToPaneMap* pMap, DWORD /*dwIgnoredOptions*/)
{
    ASSERT(pMap);

    MyXTPDockingPane* pPane = (MyXTPDockingPane*)GetDockingPaneManager()->OnCreatePane( GetType(), pLayout);

    MyXTPTaskPanel* pPanel = dynamic_cast<MyXTPTaskPanel*>(pPane->GetChild());

    if(pPanel)
    {
        pPanel->DestroyWindow();
        pPanel = NULL;
    }

    pPane->Copy(this);
    pPane->Attach(GetChild());

    m_hwndChild = 0;

    pMap->SetAt(this, pPane);


    return pPane;
}

This works as far as i can see and hope this won't result in other problems.


with regards

Andreas
