Can you not create the cache and remove the panes and then create and save the layout?

Have you changed the xml to verify it is the count?

Hi All

When I'm saving the layout of my docking panes I want to filter out unwanted panes so that they don't get modified when I do a restore later on. In the following code snippet I'm attempting to do this. I'm creating a new pane layout object, removing the docking panes I don't want from the pane list, and then doing a property exchange on that.

CXTPPropExchangeSection pxDockingPane(pPX->GetSection(_T("DockingPane")));
if (!pPX->IsLoading ())
  {
  CXTPDockingPaneLayout *pLayout = m_paneManager.CreateLayout ();
  m_paneManager.GetLayout (pLayout);
  if (pLayout)
    {
    std::set<int> idSet;
    idSet.insert (ID_PANE_1);
    idSet.insert (ID_PANE_2);
    idSet.insert (ID_PANE_3);

    // Remove unwanted panes before exchange.
    CXTPDockingPaneInfoList cache;
    CXTPDockingPaneInfoList &paneList = pLayout->GetPaneList ();
    POSITION pos = paneList.GetTailPosition();
    while (pos)
      {
      CXTPDockingPane* pPane = paneList.GetAt (pos);
      if (idSet.find (pPane->GetID ()) != idSet.end ())
        {
        cache.AddTail (paneList.GetAt (pos));
        paneList.RemoveAt (pos);
        }
      paneList.GetPrev (pos);
      }
    pLayout->DoPropExchange (&pxDockingPane);
    delete pLayout;
    }
  }

And here is the generated layout…

<Settings CompactMode="1">
  <CustomLayout>
    <DockingPane>
      <Summary Panes="21" TopContainer="4" Client="9"/>
      <Pane-1 Type="0" DockingCX="220" DockingCY="150" Title="Forms\n" ID="40" DockingHolder="7" LastHolder="7" MinTrackX="100" MinTrackY="100"/>
      <Pane-2 Type="0" DockingCX="200" DockingCY="120" Title="MyApplication:2\n\n" ID="501" Options="16" DockingHolder="10" FloatingHolder="13" LastHolder="13"/>
      <Pane-3 Type="5" Direction="0" Panes="0"/>
      <Pane-4 Type="2" Panes="1" Pane-1="5"/>
      <Pane-5 Type="2" DockingCX="1280" DockingCY="723" Horiz="1" Panes="2" Pane-1="6" Pane-2="8"/>
      <Pane-6 Type="2" DockingCX="223" DockingCY="876" Panes="1" Pane-1="7"/>
      <Pane-7 Type="1" DockingCX="220" DockingCY="494" Panes="3" Pane-1="0" Pane-2="0" Pane-3="0"/>
      <Pane-8 Type="2" DockingCX="1178" Panes="2" Pane-1="9" Pane-2="10"/>
      <Pane-9 Type="4"/>
      <Pane-10 Type="1" DockingCX="200" DockingCY="120" Panes="0"/>
      <Pane-11 Type="3" WindowRectTopPos="49" WindowRectBottomPos="429" WindowRectLeftPos="775" WindowRectRightPos="1359" TopContaner="12"/>
      <Pane-12 Type="2" DockingCX="200" DockingCY="120" Horiz="1" Panes="1" Pane-1="13"/>
      <Pane-13 Type="1" DockingCX="200" DockingCY="120" Panes="1" Selected="2" Pane-1="2"/>
    </DockingPane>
  </CustomLayout>
</Settings>

All good so far. So now for my problem.

Loading the saved layout crashes. I think that it's because <Summary Panes="21" TopContainer="4" Client="9"/> is wrong (it is still referring to the original number of panes before I removed some of them). Unfortunately that value is retrieved from a private member in the CXTPDockingPaneLayout class so I can't change it. I guess I could just change the XML but that seems pretty hacky.

Any thoughts / ideas? Ideally I'd like to override CXTPDockingPaneLayout::_Save but obviously that has been abstracted away for good reasons.]]> Thu, 14 Feb 2013 01:25:03 +0000 http://forum.codejock.com/forum_posts.asp?TID=20611&PID=69700&title=cxtpdockingpanelayoutdopropexchange-filtering#69700
